Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of computer technology, and in particular to a singleton object loading method and device, a storage medium and an electronic device. BACKGROUND

[0002] In modern software development, the singleton pattern is a common design pattern that aims to ensure that only one instance of a class exists and provides a global access point. This pattern is widely used in many applications, especially in scenarios that require shared state or resource management. However, traditional singleton object creation methods often face a series of problems, affecting the performance and resource utilization efficiency of the application.

[0003] However, existing singleton object creation methods usually require all singleton objects to be initialized during the program startup phase. Although this approach can ensure the availability of singleton objects to some extent, it also causes significant resource waste and performance overhead. Especially in large-scale applications, many singleton objects may not be accessed or needed during the actual use of the user, which leads to waste of memory and computing resources.

[0049] Exemplary embodiments of the present application will be described herein below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it is understood that the present application can be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

[0050] In modern software development, singleton pattern is a design pattern that aims to ensure that a class has only one instance and provides a global access point. While this pattern is very common in scenarios that require sharing state or managing resources, traditional singleton object creation methods often have problems of performance and resource utilization efficiency. Generally, existing methods require all singleton objects to be initialized in the program startup phase, which, while ensuring the availability of objects, also leads to resource waste and performance overhead. Especially in large applications, many singleton objects may not be accessed or needed during actual use, resulting in unnecessary consumption of memory and computing resources.

[0051] To solve this problem, the industry has proposed some on-demand loading strategies. A common approach is to hardcode the singleton object creation logic into the page to achieve on-demand loading of singletons. However, this method has obvious shortcomings. First, the hardcoding approach creates singleton objects according to fixed logic every time the page is loaded, even if these objects are not necessarily needed in the current user's context. Such an approach not only reduces the flexibility of the system, but also increases the complexity of maintenance. In the case of changes in business requirements or different user contexts, it is difficult to effectively adjust the hard-coded logic, making it difficult for the system to adapt to real-time changing requirements.

[0052] In summary, the resource waste and performance overhead caused by the traditional method of loading singleton objects in bulk at program startup, and the lack of flexibility in existing technologies through hardcoding to achieve on-demand loading of singletons, both indicate that the current singleton management strategy needs to be improved.

[0053] Based on this, in the embodiments of the present application, a singleton object loading method is provided. When a terminal device starts a target application, the page routing configuration table of the application is first loaded asynchronously. The table contains multiple page routing definitions, corresponding page singleton service information, and the business function enablement status thereof. When a user accesses a page, the page routing configuration table is checked to confirm whether there is a corresponding page routing definition. If there is, the singleton service information related thereto is identified. For singleton services that have been enabled, the corresponding singleton object is searched in a preset object pool. If found, the object is loaded, and the preset object pool stores multiple singleton objects configured in advance. It can be seen that the present application optimizes the creation and management mode of singleton objects through the page routing configuration table, which not only improves the performance of the system, but also enhances the adaptability of the system to business demands, and realizes more efficient resource utilization.

[0054] As Figure 1 shown, the flowchart of an embodiment of the singleton object loading method provided by the embodiments of the present application, the method can include:

[0055] S100, in the case of starting a target application in a terminal device, the page routing configuration table of the target application is loaded asynchronously, wherein the page routing configuration table includes the page singleton object information of the target application, the page singleton object information includes the page routing definition information of each page in the target application, at least one page singleton service information in a mapping relationship with the page routing definition information, and the business function enablement status corresponding to the page singleton service information.

[0056] Wherein, the terminal device refers to the hardware device used by the user, such as smart phone, tablet computer, personal computer, etc. The terminal device can run application program, process user input and display content.

[0057] Wherein, the target application refers to the specific software or program started by the user on the terminal device, such as social media application, e-commerce platform, game or other functional application. The target application provides specific functions and interfaces to meet the needs of users.

[0058] Wherein, asynchronous loading is a programming technique that allows an application to perform certain operations in the background without blocking the main thread or user interface.

[0059] Wherein, the page routing configuration table is a data structure containing the routing information of each page in the target application. The page routing configuration table records all the pages of the application and their corresponding access paths (routes), as well as the service and function status related to these pages.

[0060] The page singleton object information refers to the detailed information of the singleton object associated with a page in the application. A singleton object is an object that will only have one instance created during the application's runtime. Singleton objects usually contain the state and behavior of a page, ensuring that they can be efficiently used and accessed in different contexts.

[0061] The page route definition information refers to a specific entry in the page route configuration table, describing the unique identifier or access path of a certain page. Page route definition information defines how a user navigates to the corresponding page and usually includes a URL or a specific path string.

[0062] The page singleton service information refers to the service information associated with a specific page route definition information. These services are usually components that handle the business logic of the page and can include data acquisition, state management, etc. Page singleton services exist in singleton mode, ensuring that only one instance handles specific page logic throughout the application's lifecycle.

[0063] The business function enablement status refers to whether the function related to the page singleton service information is enabled in the current application environment. It is usually represented by a Boolean value (such as "enabled" or "disabled"). The business function enablement status determines whether a specific function can be used when a user accesses the relevant page, affecting the behavior of the page and the user experience.

[0064] Specifically, when the user starts the target application on a mobile device, the embodiment of the application can use a library that handles network requests (such as URLSession (iOS) or OkHttp (Android)) to perform asynchronous HTTP requests and handle server responses through callback functions to asynchronously obtain the latest page route configuration table of the target application from the server.

[0065] Optionally, in the case of network fluctuations or server failures causing the page route configuration table acquisition request to fail, the embodiment of the application can automatically retry the page route configuration table acquisition request. After retrying a preset number of times, if the acquisition request still fails, switch to the page route configuration table in the local cache of the last successful request to ensure that the application can run smoothly and provide a good user experience.

[0066] S110, in the case of opening the target page of the target application, query whether the target page route definition information of the target page exists in the page route configuration table, if so, execute step S120.

[0067] Specifically, when a user opens a target page of a target application, the embodiment of the application queries a page routing configuration table to determine whether there is page routing definition information of the target page. If the corresponding page routing definition information is found, it means that the target page is supported and can be loaded, and then the next step is executed.

[0068] Optionally, the embodiment of the application can normally load the target page in the case where the page routing configuration table query does not find the target page routing definition information of the target page, that is, the target page does not involve singleton creation logic. The embodiment of the application provides normal page loading logic for the scenario where the target page does not involve singleton creation logic, and can ensure that the user normally experiences the target page.

[0069] S120, confirming each target page singleton service information that has a mapping relationship with the target page routing definition information.

[0070] Specifically, the embodiment of the application confirms all singleton service information related to the target page routing definition information, that is, the singleton service associated with the current page, to identify the page service component that needs to be loaded.

[0071] S130, for the target page singleton service information whose business function enablement state is enabled, querying whether there is a target page singleton object corresponding to the target page singleton service information in a preset object pool, and if so, performing step S140.

[0072] The preset object pool stores a plurality of singleton objects that have been configured.

[0073] Specifically, the embodiment of the application finds whether there is a page singleton object corresponding to the service in a preset object pool for the page singleton service whose business function enablement state is enabled. If the page singleton object is found in the object pool, the page singleton object does not need to be re-created and can be directly used. The embodiment of the application maintains a pool of created singleton objects to ensure that each singleton object is created only once, thereby avoiding resource waste caused by repeated creation of the same singleton object.

[0074] S140, loading the target page singleton object.

[0075] Specifically, the embodiment of the application can load the page singleton object found in the preset object pool for the target page to be used for operation of the target page. The embodiment of the application loads the singleton object only when the routing has been configured and the business function is in an activated state, thereby effectively avoiding application performance degradation and invalid resource consumption.

[0076] In actual applications, due to business logic reasons (such as AB testing or function offline, etc.), some singleton objects do not need to be created, and the corresponding target page singleton service information can be set to the disabled state of the business function to indicate that the corresponding singleton object does not need to be created.

[0077] The scenario of the business function being set to the disabled state can include product testing phase, certain user groups not opening some functions, or temporary function offline, etc. The purpose of setting the "enable switch" is to flexibly control the release and disablement of functions, thereby avoiding unnecessary resource occupation and user experience confusion, and ensuring reasonable and efficient management of singleton objects in the application. For example, during the audit of the application program, if a certain business function cannot pass the audit due to some reasons, the business function enable state can be configured as "disabled", thereby prohibiting the creation of related singleton objects and achieving service disablement.

[0078] It can be understood that the page routing definition information can have a mapping relationship with a plurality of page singleton service information, and in these page singleton service information, the application embodiment can skip the creation of the page singleton object whose business function enable state is disabled, and continue to load the page singleton object whose business function enable state is enabled. For the uncreated page singleton object, the application embodiment can hide the content or prompt related to the function of the page singleton object in the loaded target page, and ensure the normal operation of the functions of other created page singleton objects.

[0079] Optionally, in the case where the business function enable state of any page singleton service information of the target application is disabled, the application embodiment can guide the user to view a preset error page or a preset default page, or prompt the user to perform application check and update, so as to ensure that the user experience is not affected. Under the dynamic on-demand loading mechanism, the application embodiment provides a corresponding bottom strategy for a plurality of singleton object creation scenarios that do not need to be created, can maintain the robustness of the underlying code, and guarantee the service experience of the user.

[0080] The application provides a singleton object loading method, which comprises the following steps: in the case that a terminal device starts a target application, asynchronously loading a page route configuration table of the target application, wherein the page route configuration table comprises a plurality of page route definition information, at least one page singleton service information in a mapping relationship with the page route definition information, and a business function enabling state corresponding to the page singleton service information; in the case that a target page of the target application is opened, querying whether there is target page route definition information of the target page in the page route configuration table, and if yes, confirming each target page singleton service information in a mapping relationship with the target page route definition information; for the target page singleton service information with the business function enabling state being enabled, querying whether there is a target page singleton object corresponding to the target page singleton service information in a preset object pool, and if yes, loading the target page singleton object, wherein the preset object pool stores a plurality of singleton objects configured in advance. The application realizes dynamic on-demand loading of singleton objects through the page route configuration table, can reasonably utilize computer resources to manage the creation and loading of singleton objects, and thus effectively improves the system resource utilization efficiency and the starting performance.

[0081] Optionally, in the above Figure 1 Based on one or more embodiments, another optional embodiment provided by the application comprises the following steps:

[0082] In the case that it is queried that there is no target page singleton object corresponding to the target page singleton service information in the preset object pool, the target page singleton object is created by using the target page singleton service information; after the target page singleton object is created, the target page singleton object is loaded, and the target page singleton object is added to the preset object pool.

[0083] In the case that it is queried that there is no target page singleton object corresponding to the target page singleton service information in the preset object pool, the target page singleton object is created by using the target page singleton service information; after the target page singleton object is created, the target page singleton object is loaded, and the target page singleton object is added to the preset object pool.

[0084] Specifically, the singleton service information for a page typically includes configuration information, dependencies, and initialization parameters required for the page's business logic. This embodiment of the invention reads this information and initializes the singleton object according to a predetermined creation process. This creation process may include: First, obtaining the initial configuration required by the target page from the singleton service information, such as specific business rules, database connections, and external dependent services. Second, initializing other resources or objects that the singleton object depends on, such as configuration loading and service calls, based on the description in the singleton service information. Finally, using the initial configuration and dependencies, calling the constructor or factory method of the target singleton object to instantiate it.

[0085] In this embodiment of the invention, after the singleton object is created, it is loaded into memory, ready for use by the target page. Simultaneously, to avoid duplicate creation, the singleton object is stored in a preset object pool so that subsequent requests for the same page can reuse the singleton object.

[0086] This invention, through page route definition information in the page route configuration table, can dynamically create and load singleton objects when needed, thereby avoiding the pre-allocation of unnecessary resources during application startup. Simultaneously, it maintains a pool of created singleton objects, ensuring that each singleton object is created only once, thus avoiding resource waste caused by duplicate creation.

[0087] For example, taking the MGTV APP as an example, its homepage tab contains multiple channel pages. Using the singleton object loading method provided in this embodiment of the invention, recommendation algorithm singletons related to each page can be dynamically loaded according to the page routing configuration table. When a user visits the "Homepage," only the recommendation algorithm singleton corresponding to the homepage is created and loaded; while when the user switches to the "TV Series" channel, the singleton corresponding to that channel is created and loaded, thus effectively avoiding the preloading of useless singletons and improving the application's efficiency and response speed.

[0088] In traditional on-demand loading methods, failure to create a singleton object can lead to business errors or UI chaos. However, in scenarios where singletons are dynamically created based on page routes, the code already fully considers the possibility of the singleton not being enabled. Therefore, even if singleton object creation fails, a fallback strategy can be implemented by referencing an interface where the singleton is not enabled. This can be done by skipping the creation of the singleton object, guiding the user to view a preset error page or default page, or prompting the user to check for application updates, thus ensuring that the user experience is not affected.

[0089] Optional, based on Figure 1 The method shown is as follows: Figure 2As shown, the flowchart of another embodiment of the singleton object loading method provided by the embodiment of the application is shown, and before loading the page route configuration table of the target application asynchronously, the method can further include:

[0090] S200, obtaining page route definition information of each page in the target application.

[0091] Specifically, the embodiment of the application can collect and organize the URL path, page class name and other key information of all pages in the target application, so as to obtain the page route definition information of each page in the target application.

[0092] S210, respectively constructing a mapping relationship between the page route definition information and the at least one page singleton service information, and setting a business function enablement state corresponding to the page singleton service information, so as to generate page singleton object information of the target application.

[0093] Specifically, the embodiment of the application can determine the singleton object (service or component) required by each page, and set the enablement state of the singleton object according to the business requirement. By constructing the mapping relationship between the page route definition information and the page singleton service information, the singleton object required by each page at runtime is determined, and the corresponding page singleton object information is generated.

[0094] S220, creating a page route configuration table of the target application by using at least the page singleton object information.

[0095] Specifically, the embodiment of the application can use the generated page singleton object information to construct the page route configuration table of the target application, so as to summarize the route information of each page, the corresponding singleton object and the enablement state thereof.

[0096] The embodiment of the application can dynamically manage the relationship between the application page and the singleton object by creating the page route configuration table of the target application, so as to facilitate the creation of the singleton object on demand, so as to improve the resource utilization efficiency and adapt to the change of the business requirement.

[0097] Optionally, in the above Figure 2 Based on one or more embodiments corresponding thereto, another optional embodiment provided by the embodiment of the application can further include:

[0098] Setting a singleton object destruction attribute corresponding to the page singleton service information. In the case of exiting the target page, destroying the singleton object destruction attribute of the target page singleton object.

[0099] The singleton object destruction attribute refers to an attribute for indicating whether a certain singleton object should be destroyed or release its resource under the condition of exiting the target page.

[0100] In particular, the embodiment of the present application defines a singleton object destroy attribute for each page singleton service information. The singleton object destroy attribute is usually a Boolean value, and can be named "destroyOnExit" or similar identifiers.

[0101] When the user exits from the target page or navigates to other pages, the embodiment of the present application can determine the singleton object destroy attribute of the singleton object used in the current page. If the singleton object destroy attribute is set to a true value (for example, true), the singleton object is destroyed to release the resources occupied by the singleton object, thereby avoiding unnecessary memory occupation.

[0102] The embodiment of the present application can effectively manage the life cycle of the singleton object by setting the singleton object destroy attribute, so that the application can maintain high efficiency and performance while reasonably using system resources.

[0103] Optionally, based on the method shown in FIG. 2, the embodiment of the present application provides another embodiment of a singleton object loading method, and a flowchart of the method is shown in FIG. 3. Before asynchronously loading the page routing configuration table of the target application, the method can further include: Figure 2 Figure 3 The embodiment of the present application provides another embodiment of a singleton object loading method, and a flowchart of the method is shown in FIG. 3. Before asynchronously loading the page routing configuration table of the target application, the method can further include:

[0104] S300, obtaining at least one global singleton service information of a target application.

[0105] The global singleton service information refers to instance service or object information defined by the target application in the entire application range. The global singleton service information includes some core functions or states of the target application, so that each part of the entire application can be accessed and used.

[0106] In particular, the embodiment of the present application can obtain the global singleton service information of the target application from the configuration file, the service registry center or other sources of the target application.

[0107] S310, respectively setting the business function enable states corresponding to each global singleton service information to generate global singleton object information of the target application.

[0108] The global singleton object information refers to detailed information of a specific instance or object associated with the global singleton service information.

[0109] In particular, the embodiment of the present application sets the business function enable state corresponding to the global singleton service information after obtaining the global singleton service information, and determines the global singleton object required by the application at runtime, thereby generating the corresponding global singleton object information.

[0110] Step S220 can be specifically step S320. ​

[0111] S320, constructing a page routing configuration table of the target application by using the page singleton object information and the global singleton object information.

[0112] The page routing configuration table constructed by the page singleton object information and the global singleton object information can be as shown in the following table. Figure 4 The page routing configuration table is requested from the server only at the cold start of the application, and therefore the page routing configuration table does not change during the running of the application. This means that the state of the singleton object is not affected by the configuration change during the running of the application. If the page routing configuration table is changed after the cold start, the changes will take effect at the next cold start. Therefore, the runtime does not need to handle the "expiration" problem of the singleton object. The singleton object is only recreated or initialized according to the new page routing configuration table at the cold start, thereby ensuring the stability of the system and the effective use of resources.

[0113] The instance structure pseudo code of the page routing configuration table can be as follows.

[0114]

[0115] The embodiments of the application uniformly manage the page singleton object information and the global singleton object information of the application pages by the page routing configuration table, which is beneficial to flexibly adjusting the creation and loading of the singleton objects related to the application pages, thereby helping to adapt to the real-time changes of the business requirements.

[0116] Optionally, on the basis of one or more embodiments described above, Figure 3 According to another optional embodiment of the application, the method further comprises the following steps:

[0117] In the case of opening the target page of the target application, each global singleton service information in the global singleton object information is obtained from the page routing configuration table. For the global singleton service information whose business function enablement state is enabled, it is queried whether the target global singleton object corresponding to the global singleton service information exists in the preset object pool. If yes, the target global singleton object is loaded, and if no, the target global singleton object is created by using the global singleton service information, and the target global singleton object is added to the preset object pool.

[0118] Specifically, when the user opens the target page of the target application, the embodiments of the application query the page routing configuration table to obtain each global singleton service information in the global singleton object information of the target application, i.e., the global singleton service associated with the target application, so as to identify the global service component that needs to be loaded.

[0119] Specifically, the embodiment of the present application finds whether the global singleton object corresponding to the service exists in the preset object pool for the service function enabled state being enabled. If the global singleton object is found in the object pool, the global singleton object is directly used without re-creation. The embodiment of the present application ensures that each singleton object is only created once by maintaining the pool of created singleton objects, thereby avoiding the resource waste caused by repeated creation of the same singleton object.

[0120] Specifically, the embodiment of the present application can load the global singleton object for the operation of the target page after finding the global singleton object of the target application in the preset object pool. The embodiment of the present application loads the singleton object only when the global service is configured and the business function is in the activated state, thereby effectively avoiding the application performance decline and invalid resource consumption.

[0121] It can be understood that, similar to the page singleton service information, for the global singleton service information, the embodiment of the present application can skip the global singleton object creation with the business function enabled state being disabled, and continue to load the global singleton object with the business function enabled state being enabled. The embodiment of the present application can hide the content or prompt related to the function of the global singleton object in the target page to be loaded, and ensure the normal operation of the function of other created global singleton objects.

[0122] The embodiment of the present application manages the global singleton object through the preset object pool, and loads or creates the global singleton object only when needed, which can avoid the overhead of repeated object creation, reduce resource consumption, thereby improving the response speed of the application and enhancing the overall performance of the application.

[0123] Optionally, in the above Figure 1 Based on one or more embodiments, in another optional embodiment of the present application, the page route definition information includes the page path and the page class name of the target application, and in the case of opening the target page of the target application, it is queried whether the target page route definition information of the target page exists in the page route configuration table, which can specifically include:

[0124] In the case that the user accesses the target page of the target application through the routing mechanism, the page path of the target page is obtained; the page path is used as a query condition to query whether the page route definition information matched with the page path exists in the page route configuration table, and if yes, the page route definition information is confirmed as the target page route definition information of the target page.

[0125] The page path refers to the URL path required by the user when accessing the page in the application. For example, “ / home”, “ / about” and “ / products” and the like.

[0126] Specifically, the user can navigate to the target page in the target application through clicking a link, bookmarking, or manually entering a URL, etc. The embodiment of the application uses the obtained page path as a condition to query the page routing configuration table in response to the user's request for the complete page path, and checks whether there is page routing definition information matching the path. If the query result contains a matching page path, the corresponding page routing definition information is confirmed as the target page routing definition information of the target page. This means that the application successfully found the page logic corresponding to the user's request path.

[0127] In the case where the target page accessed by the user is a hard-coded page, the page class name of the target page is obtained; the page class name is used as a query condition to query whether there is page routing definition information matching the page class name in the page routing configuration table, and if so, the page routing definition information is confirmed as the target page routing definition information of the target page.

[0128] Among them, the page class name refers to the class name corresponding to the page logic, which is usually a class defined in JavaScript or other languages, used to render and manage the logic of the page. For example: "HomePage" and "AboutPage" and the like.

[0129] In some cases, the page may not be generated by dynamic routing, but is hard-coded (for example: a page defined directly in the code). For this case, the embodiment of the application can obtain the corresponding page class name from the accessed page, and use the obtained page class name as a query condition to query the page routing configuration table, and check whether there is page routing definition information matching the page class name. If a matching page class name is found, the corresponding routing definition information is confirmed as the target page routing definition information of the target page.

[0130] The embodiment of the application confirms the routing definition information of the target page requested by the user through the page path and the page class name, so that the target application can flexibly handle different types of page access requests, which is conducive to supporting multiple access methods (path and class name) and adapting to diversified application requirements, thereby helping to improve the maintainability and user experience of the application.

[0131] To facilitate understanding of the overall process of singleton object management of the singleton object loading method provided by the embodiments of the present application, the following is described by way of example: first, initialize the singleton pool. When the application is cold started, the global singleton pool is initialized according to the globalSingletons configuration item in the page routing configuration table, and all global singleton objects such as LoggerService and DatabaseService are created and stored for shared use during application running. When processing page loading, the required singleton objects are created and managed according to the corresponding configuration matched according to different scenarios.

[0132] For a routing scenario: when a user accesses a certain page through a routing mechanism (such as UniversalLink of iPhone), a matching item is found in the path field in the configuration table according to the request path (for example: / home). The path field in the configuration table is searched for a matching request path. If a matching item is found, the corresponding page and the singleton objects required by the page are loaded. For example: a user accesses the / home route through myapp: / / home, the HomePage page is found according to the path field, and it is checked whether the UserService singleton object needs to be loaded. If the UserService does not exist in the singleton pool, the system creates and adds it to the pool.

[0133] For a non-routing scenario: for a page instantiated by a hardcoding method (for example: directly using the new keyword), the page class name (such as HomePage) is matched with the page field in the configuration table. The page class name is matched with the page field in the configuration table to determine whether the corresponding singleton object needs to be created and loaded. For example: when the HomePage is instantiated in the code, the corresponding page configuration is found according to the page field, and it is checked whether the UserService singleton object needs to be created. If the UserService does not exist in the singleton pool, the object is created and initialized.

[0134] When the page disappears, it is determined whether to destroy the singleton object according to the destroyOnExit attribute of the singleton object. If the destroyOnExit attribute is true, the singleton object is destroyed and removed from the preset object pool. If the destroyOnExit attribute is false, the singleton object is retained for subsequent use by other pages. For example: when the / profile page is accessed, if the destroyOnExit attribute of the ProfileService is true, the ProfileService instance is destroyed and removed from the object pool after the page disappears.

[0135] The embodiment of the present application avoids the situation that the singleton object occupies the memory for a long time in the prior art by dynamically loading on demand, and in particular, the resource waste is reduced by automatic destruction when the object is no longer needed. Meanwhile, the resource utilization efficiency is improved and the complexity of manual management is reduced by intelligently managing the life cycle of the singleton object.

[0136] The singleton object loading method provided by the embodiment of the present application adopts the singleton mode with flexible configuration, and in principle, is not limited by specific businesses, and is particularly suitable for large multifunctional application scenarios requiring global resource sharing and complex business logic management, and can ensure efficient and stable use of resources and improve user experience.

[0137] Although each operation is described in a particular order, this should not be understood as requiring the operations to be performed in the particular order shown or in a sequential order. In certain circumstances, multitasking and parallel processing can be advantageous.
