Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0036] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this invention are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0037] Example 1

[0038] Figure 1 This is a flowchart illustrating a data pagination query method provided in Embodiment 1 of the present invention. This embodiment is applicable to scenarios involving paginated data queries. The data pagination query method can be executed by a data pagination query device, which can be implemented in hardware and / or software. This data pagination query device can be configured in electronic devices such as computers or servers, for example, in electronic devices that provide data pagination query functionality. Figure 1 As shown, the method in this embodiment includes:

[0039] S110. In response to the data pagination query request, modify the initial pagination parameters corresponding to the data pagination query request to custom pagination parameters.

[0040] The data pagination query request can be understood as a request used to perform data pagination queries. There are several ways to obtain a data pagination query request, such as receiving a click operation on the data pagination query control and generating a data pagination query request based on the click operation; or receiving a data pagination query instruction entered in the data pagination query input box and generating a data pagination query request based on the data pagination query instruction. The data pagination query request may include the database name, query keywords, and query conditions, etc. Initial pagination parameters can be understood as default pagination parameters set for how the data query results should be paginated. In this embodiment of the invention, the initial pagination parameters are pagination parameters set in the programming for the data pagination query function. Initial pagination parameters may include the current page number, total number of records (assigned by the interceptor), total number of pages, and number of records displayed per page (initial value set to 500), etc. The number of records displayed per page can be understood as the maximum number of query data records that can be included per page. Custom pagination parameters can be understood as pagination parameters set according to actual query needs. It is understood that, in this embodiment of the invention, the custom pagination parameters may include at least one of the current page number, total number of pages, and number of items displayed per page.

[0041] Specifically, the system receives data pagination query requests. Upon receiving a data pagination query request, it can obtain custom pagination parameters and intercept the initial pagination parameters corresponding to the data pagination query request. After intercepting the initial pagination parameters, it can modify the intercepted initial pagination parameters to the obtained custom pagination parameters, thereby modifying the initial pagination parameters corresponding to the data pagination query request without modifying the code.

[0042] In this embodiment of the invention, obtaining custom pagination parameters may include: obtaining custom pagination parameters from a predefined pagination class used to create the pagination object, based on a predefined pagination object.

[0043] The predefined pagination object can be an object created based on a predefined pagination class. In other words, the predefined pagination object is an instance of a predefined pagination class. The predefined pagination object can be used to retrieve custom pagination parameters; that is, it can be used to retrieve custom pagination parameters. The predefined pagination class can be understood as a predefined class used to configure custom pagination parameters.

[0044] Specifically, a predefined pagination class is used. A pagination object is created based on this pagination class. After the pagination object is created, its methods and / or properties for setting pagination parameters can be called through the pagination object created from the pagination class; that is, the methods and / or variables in the pagination class used for setting pagination parameters can be called. This allows the access to custom pagination parameters configured in the pagination class. It is understood that custom pagination parameters can be configured in the methods and / or variables in the pagination class used for setting pagination parameters. It should be noted that after creating a pagination object based on the pagination class, the methods and / or variables in the pagination class used for setting pagination parameters can be used as methods and / or properties in the pagination object used for setting pagination parameters.

[0045] Optionally, modifying the initial pagination parameter corresponding to the data pagination query request to a custom pagination parameter may include: intercepting the pagination method corresponding to the data pagination query request; determining the initial pagination parameter in the pagination method; and modifying the initial pagination parameter to a custom pagination parameter.

[0046] The pagination method can be understood as a method with paginated query functionality. It can be used to query data and paginate the query results. The pagination method can have initial pagination parameters set.

[0047] Specifically, upon receiving a data query request, the pagination method corresponding to the request can be determined. This pagination method is then loaded into memory. After the pagination method is loaded into memory but before it runs, it can be intercepted. Upon interception, the initial pagination parameters within the method can be determined. These initial pagination parameters can then be modified to custom pagination parameters.

[0048] Optionally, intercepting the pagination method corresponding to the data pagination query request may include: invoking a predefined pagination interceptor to intercept the pagination method corresponding to the data pagination query request. The predefined pagination interceptor can be understood as a predefined interceptor used to intercept the pagination method before its execution.

[0049] Furthermore, the step of intercepting the pagination method corresponding to the data pagination query request by calling a predefined pagination interceptor may include: determining the method to be executed; if the method to be executed is determined to be the pagination method corresponding to the data pagination query request, then calling the predefined pagination interceptor to intercept the pagination method.

[0050] The method to be executed can be understood as the method that is about to be executed, that is, the method that needs to be executed in the next moment after the current moment.

[0051] In this embodiment of the invention, a method to be executed is determined. This allows the identification of the method to be executed to be determined. The identification of the method to be executed can then be compared with the identification of a pagination method. If the identification of the method to be executed matches the identification of the pagination method, then the method to be executed can be determined to be the pagination method corresponding to the data pagination query request. Therefore, a predefined pagination interceptor can be invoked to intercept the method to be executed; that is, a predefined pagination interceptor can be invoked to intercept the pagination method.

[0052] Based on the above embodiments, before invoking the predefined pagination interceptor, the method further includes: registering the pagination interceptor to facilitate efficient loading of the pagination interceptor, thereby enabling the use of the interceptor.

[0053] S120. Based on the custom pagination parameters, generate a data pagination query statement and execute the data pagination query statement to perform data pagination query in the database.

[0054] Among them, the pagination query statement can be a database execution statement generated based on custom pagination parameters, which can be used to query data in the database and paginate the query results.

[0055] Specifically, after modifying the initial pagination parameters corresponding to the data pagination query request to custom pagination parameters, a data pagination query statement can be generated based on the custom pagination parameters. This data pagination query statement can then be applied to the database and executed within the database. This allows for data querying and pagination of the query results within the database.

[0056] In this embodiment of the invention, generating a data pagination query statement based on the custom pagination parameters may include: reassigning the custom pagination parameters to the input parameters of the pagination query statement generation method corresponding to the data pagination query request based on a predefined parameter setting object; and after the assignment is completed, calling the pagination query statement generation method to generate the data pagination query statement.

[0057] The parameter setting object can be used to reassign custom parameters to the input parameters of the pagination query generation method. The pagination query generation method can be a predefined method for generating pagination queries. The input parameters of the pagination query generation method can be understood as the formal parameters of the pagination query generation method. Reassigning custom pagination parameters to the input parameters of the pagination query generation method can be understood as assigning the custom pagination parameters as actual parameters to the formal parameters of the pagination query generation method.

[0058] The technical solution of this invention receives a data pagination query request and modifies the initial pagination parameters corresponding to the request to custom pagination parameters. Then, based on the custom pagination parameters, a data pagination query statement can be generated and executed to perform data pagination queries in the database. This technical solution not only enables more flexible data pagination queries but also avoids data pagination query anomalies caused by version conflicts.

[0059] Example 2

[0060] Embodiment 3 of this invention provides an optional embodiment of a data pagination query method, taking the built-in pagination plugin of MybatisPlus as an example, and performing data pagination queries based on the built-in pagination plugin of MybatisPlus. Specific implementation details can be found in the following embodiments. Technical terms that are the same as or corresponding to those in the above embodiments will not be repeated here.

[0061] The method in this embodiment specifically includes the following steps:

[0062] 1. When the MybatisPlus built-in pagination plugin receives a data pagination query request, it can determine the method to be executed. If the method to be executed is a pagination method corresponding to the data pagination query request, a predefined pagination interceptor can be called to intercept the pagination method.

[0063] 2. After intercepting the pagination method, custom pagination parameters can be obtained from the predefined pagination class (Page class) used to create the pagination object, based on a predefined pagination object (Page object). The initial pagination parameters in the pagination method can also be determined. Furthermore, the initial pagination parameters can be modified to custom pagination parameters. In other words, the initial pagination parameters in the pagination method can be modified to custom pagination parameters.

[0064] 3. After modification, the custom pagination parameters can be reassigned to the entry parameters of the pagination query statement (pagination query SQL) generation method corresponding to the data pagination query request based on the predefined parameter setting object (StatementHandler).

[0065] 4. After the assignment is complete, the pagination query statement generation method is called to generate the data pagination query statement. The data pagination query statement can then be executed to perform data pagination queries in the database.

[0066] The technical solution of this invention, based on the built-in pagination plugin of MybatisPlus, can intercept the database pagination query statement that needs to be paginated from the source, and concatenate the database pagination query statement that meets the business requirements to realize a new pagination plugin. This not only enables more flexible pagination querying of data, but also avoids the situation where data pagination query is abnormal due to version conflicts.

[0067] Example 3

[0068] Figure 2 This is a schematic diagram of a data pagination query device provided in Embodiment 3 of the present invention. Figure 2 As shown, the device includes a parameter modification module 210 and a pagination query module 220.

[0069] The parameter modification module 210 is used to modify the initial pagination parameters corresponding to the data pagination query request to custom pagination parameters in response to the data pagination query request; the pagination query module 220 is used to generate a data pagination query statement based on the custom pagination parameters and execute the data pagination query statement to perform data pagination query in the database.

[0070] The technical solution of this invention receives a data pagination query request through a parameter modification module, and modifies the initial pagination parameters corresponding to the data pagination query request to custom pagination parameters. Then, a pagination query module can generate a data pagination query statement based on the custom pagination parameters, and execute the data pagination query statement to perform data pagination queries in the database. The technical solution of this invention not only enables more flexible data pagination queries but also avoids data pagination query anomalies caused by version conflicts.

[0071] Optionally, the device further includes a custom parameter acquisition module, used to acquire custom paging parameters from a predefined paging class used to create the paging object, based on a predefined paging object.

[0072] Optionally, a custom parameter acquisition module is specifically used to intercept the pagination method corresponding to the data pagination query request; determine the initial pagination parameters in the pagination method; and modify the initial pagination parameters to custom pagination parameters.

[0073] Optionally, the custom parameter acquisition module includes a method interception unit, which is used to call a predefined pagination interceptor to intercept the pagination method corresponding to the data pagination query request.

[0074] Optionally, the method interception unit is specifically used to determine the method to be executed. If the method to be executed is determined to be a pagination method corresponding to the data pagination query request, then a predefined pagination interceptor is invoked to intercept the pagination method.

[0075] Optionally, the device further includes an interceptor registration module for registering the pagination interceptor before the predefined pagination interceptor is invoked.

[0076] Optionally, the pagination query module 220 is specifically used to reassign the custom pagination parameters to the entry parameters of the pagination query statement generation method corresponding to the data pagination query request based on a predefined parameter setting object; after the assignment is completed, the pagination query statement generation method is called to generate the data pagination query statement.

[0077] The data pagination query device provided in this embodiment of the invention can execute the data pagination query method provided in any embodiment of the invention, and has the corresponding functional modules and beneficial effects of the execution method.

[0078] It is worth noting that the various units and modules included in the above-mentioned data pagination query device are only divided according to functional logic, but are not limited to the above division, as long as the corresponding functions can be achieved; in addition, the specific names of each functional unit are only for easy differentiation and are not used to limit the protection scope of the embodiments of the present invention.
