Developers still need to do a lot of manual coding work, and they also need to modify, test and integrate in the target business scenarios, which results in a lot of complex and tedious development work, affecting the progress of software development.

[0020] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings.

[0021] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0022] It should be noted that in the technical solution of the present disclosure, the collection, storage, use, processing, transmission, provision and disclosure of user personal information are all carried out with the user's consent, and are in compliance with the relevant laws and regulations and do not violate public order and good morals.

[0023] In view of the above problems, the present disclosure proposes a code generation method and device.

[0024] The code generation method and device according to the embodiments of the present disclosure are described below with reference to the accompanying drawings.

[0025] Figure 1 A flowchart of a code generation method provided by an embodiment of the present disclosure.

[0026] like Figure 1 As shown, the code generation method includes the following steps:

[0027] Step 101: Obtain a target business model under a target business scenario.

[0028] It can be understood that the business scenario is the construction environment in which the business is located, for example, the financial business scenario is the construction environment in which the financial business is located. This embodiment does not specifically limit the target business scenario.

[0029] In addition, it should be noted that business personnel related to the target business scenario analyze the information contained in the target business scenario and perform modeling to determine the business modeling results, wherein the business modeling results are the target business model.

[0030] In addition, it should be noted that different target business scenarios have different target business models under the target business scenarios.

[0031] Step 102 , based on the target business model, generate the initial source code and the code of the business service level in the microservice architecture through the pre-set code engineering scaffolding.

[0032] It should be noted that the target business model at least includes a product model, a process model and a data model, and the business service layer includes an interface layer, an application layer, a domain layer and a permanent layer.

[0033] In addition, it should be noted that the pre-set code engineering scaffolding contains multiple mapping relationships.

[0034] In order to accurately convert the target business model into the initial source code and the code at the business service level in the microservice architecture, as a possible implementation method, based on the target business model, the initial source code and the code at the business service level in the microservice architecture are generated through various mapping relationships contained in the pre-set code engineering scaffolding.

[0035] As an example, based on the first data contained in the product model, a code conversion tool is used to generate initial source code; based on the target business model, various mapping relationships contained in the code engineering scaffolding are used to determine the interface layer and application layer that have a mapping relationship with the product model in the business service layer, the domain layer that has a mapping relationship with the process model in the business service layer, and the domain layer that has a mapping relationship with the data model in the business service layer; according to the business service layer that has a mapping relationship with the product model in the business service layer, the code of the interface layer and the code of the application layer are determined, and according to the business service layer that has a mapping relationship with the process model in the business service layer and the business service layer that has a mapping relationship with the data model in the business service layer, the code of the domain layer is determined; the code of the domain layer is deduced to determine the code of the permanent layer; according to the code of the interface layer, the code of the application layer, the code of the domain layer, and the code of the permanent layer, the code of the business service layer in the microservice architecture is determined.

[0036] In order to completely generate the code of the interface layer, the application layer, the domain layer and the permanent layer, as a possible implementation method, the code of the interface layer and the application layer are determined according to the business service layer that has a mapping relationship with the product model in the business service layer, and the code of the domain layer is determined according to the business service layer that has a mapping relationship with the process model in the business service layer and the business service layer that has a mapping relationship with the data model in the business service layer.

[0037] As an example, according to the mapping relationship between the product model and the interface layer, the second data contained in the product model is mapped to the interface layer, and the code of the interface layer is generated through a code conversion tool. According to the mapping relationship between the product model and the application layer, the second data contained in the product model is mapped to the application layer, and the code of the application layer is generated through a code conversion tool. According to the mapping relationship between the process model and the domain layer, the data contained in the process model is mapped to the domain layer, and the code of the domain layer is generated through a code conversion tool. According to the mapping relationship between the data model and the domain layer, the data contained in the data model is mapped to the domain layer, and the code of the domain layer is generated through a code conversion tool.

[0038] In addition, it should be noted that the first data contained in the product model is used to represent part of the data contained in the product model. For example, assuming that the product model contains basic products, business capabilities, ancillary services, product functions, business functions and service function data, among which the basic products, business capabilities and ancillary services can be divided into a group of data, which is the first data contained in the product model, and product functions, business functions and service functions can be divided into another group of data, which is the second data contained in the product model.

[0039] Step 103: Generate a service configuration file associated with the code at the business service level according to the code at the business service level in the microservice architecture.

[0040] The service configuration file is used to represent the file loaded when executing the code at the business service level in the microservice architecture.

[0041] Step 104 , encapsulate the business service level code and service configuration files in the microservice architecture into the initial source code to determine an executable target source code for satisfying the target business model.

[0042] In order to quickly execute the code at the business service level in the microservice architecture by loading the service configuration file, as an example, the service configuration file is encapsulated into the microservice architecture; and the code at the business service level in the microservice architecture and the service configuration file are encapsulated into the initial source code.

[0043] In summary, the target business model under the target business scenario is obtained; based on the target business model, the initial source code and the code of the business service level in the microservice architecture are generated through the pre-set code engineering scaffolding; according to the code of the business service level in the microservice architecture, a service configuration file associated with the code of the business service level is generated, wherein the service configuration file is used to represent the file loaded when the code of the business service level in the microservice architecture is executed; the code of the business service level in the microservice architecture and the service configuration file are encapsulated into the initial source code to determine the executable target source code for satisfying the target business model, thereby, based on the target business model, Through the pre-set code engineering scaffolding, since the code engineering scaffolding contains various mapping relationships between the target business model and the business service level in the microservice architecture, in the code generation project, there is no need for complex analysis, and the various data contained in the target business model can be mapped to the corresponding business service level, which simplifies the process of generating the target source code and avoids a large amount of complex and repetitive code coding work. Moreover, through the code engineering scaffolding, the various data contained in the target business model can be perfectly and fully converted into business service level code, so as to generate the target source code that meets the business model, thereby improving the efficiency of converting the business model into code.

[0044] In order to clearly illustrate how to generate a service configuration file associated with the code at the business service level according to the code at the business service level in the microservice architecture in the above embodiment, the present disclosure proposes another code generation method.

[0045] Figure 2 It is a flowchart of the code generation method shown in the second embodiment of the present disclosure.

[0046] like Figure 2 As shown, the code generation method includes the following steps:

[0047] Step 201: Obtain a target business model in a target business scenario.

[0048] Step 202 , based on the target business model, generates initial source code and business service level code in the microservice architecture through a pre-set code engineering scaffold.

[0049] Step 203: Determine a product model that has a mapping relationship with the interface layer code and the application layer code according to the interface layer code and the application layer code in the microservice architecture.

[0050] For example, assume that the product model includes basic products, business capabilities, ancillary services, product functions, business functions and service function data, among which there is a mapping relationship between product functions, business functions and service functions and the interface layer and application layer.

[0051] Step 204 : Determine, based on the second data included in the product model, a service configuration file in a first set format to be loaded when executing the code of the interface layer and the code of the application layer in the microservice architecture.

[0052] For example, if the business function or service function is saved in a service configuration file in json format, the service configuration file in json format can be directly loaded and run when starting the microservice architecture.

[0053] In addition, it should be noted that the specific format of the service configuration file in the first set format may be determined according to actual conditions, and this embodiment does not specifically limit it.

[0054] Step 205: According to the code of the domain layer in the microservice architecture, determine the process model that has a mapping relationship with the code of the domain layer.

[0055] For example, assume that the process model includes business activities, tasks, and processes, where there is a mapping relationship between the business activities, tasks, and processes and the domain layer.

[0056] Step 206 : Determine, based on the data included in the process model, a service configuration file in a second set format to be loaded when executing the code of the domain layer and the code of the persistent layer in the microservice architecture.

[0057] For example, business activities generate the code of the domain layer in the microservice architecture based on the target business model through the pre-set code engineering scaffolding and save it in XML format. When the microservice architecture is started, the service configuration file in XML format can be directly loaded and run.

[0058] In addition, it should be noted that the specific format of the service configuration file in the second set format may be determined according to actual conditions, and this embodiment does not specifically limit it.

[0059] It should be understood that since the code of the permanent layer is determined by deducing the code of the domain layer, when the service configuration file of the second setting format is loaded, not only the code of the domain layer in the microservice architecture can be executed, but also the code of the permanent layer in the microservice architecture can be executed.

[0060] Step 207 , encapsulate the business service level code and service configuration files in the microservice architecture into the initial source code to determine an executable target source code for satisfying the target business model.

[0061] In order to quickly execute the code of the business service level in the microservice architecture by loading the first set format service configuration file and the second set format service configuration file, as an example, the first set format service configuration file and the second set format service configuration file are encapsulated into the microservice architecture; and the first set format service configuration file and the second set format service configuration file in the microservice architecture are encapsulated into the initial source code.

[0062] It should be noted that the execution process of step 201, step 202 and step 207 can be implemented in any way in the embodiments of the present disclosure, and the embodiments of the present disclosure do not limit this and will not be described in detail.

[0063] In summary, according to the code of the interface layer and the code of the application layer in the microservice architecture, a product model that has a mapping relationship with the code of the interface layer and the code of the application layer is determined; based on the second data contained in the product model, a service configuration file of a first set format loaded when executing the code of the interface layer and the code of the application layer in the microservice architecture is determined; according to the code of the domain layer in the microservice architecture, a process model that has a mapping relationship with the code of the domain layer is determined; according to the code of the domain layer in the microservice architecture, a process model that has a mapping relationship with the code of the domain layer is determined. Therefore, when the microservice architecture is started, the execution of the code at the business service level is realized by loading the service configuration file. When the current business needs change, directly modifying the code at the business service level will cause inconsistencies between the code and the business model, and it is difficult to maintain and modify it later. By modifying the service configuration file, adaptive adjustment of the code is achieved to meet new business needs, taking into account the freshness between the code and the business model.

[0064] In order to clearly illustrate that in the above embodiment, before encapsulating the business service layer code and service configuration files in the microservice architecture into the initial source code to determine the executable target source code for satisfying the target business model, the present disclosure proposes another code generation method.

[0065] Figure 3 It is a flowchart of the code generation method shown in the third embodiment of the present disclosure.

[0066] like Figure 3 As shown, the code generation method includes the following steps:

[0067] Step 301: Obtain a target business model under a target business scenario.

[0068] Step 302 , based on the target business model, generate initial source code and business service level code in the microservice architecture through a pre-set code engineering scaffold.

[0069] Step 303: Generate a service configuration file associated with the code at the business service level according to the code at the business service level in the microservice architecture.

[0070] Step 304, based on the code of the business service layer in the microservice architecture, generate implementation classes for the interface layer, application layer and domain layer, and based on the implementation classes, generate code for the implementation layer.

[0071] It is important to understand that when generating the target source code, the code of the business service layer in the microservice architecture includes the interface layer code, application layer code, domain layer code and permanent layer code. The code of the business service layer includes the most basic interfaces and classes in the target business model of software development. This part of the code is prone to repeated development and is cumbersome. Through the code engineering scaffolding, the code of the business service layer can be quickly generated. In order to adapt to new business needs in different business scenarios, the code of the implementation layer is generated based on the code of the business service layer, and the code of the business service layer and the code of the implementation layer are separated and encapsulated into the target source code. Therefore, when migrating the target source code to a new business scenario, the code of the business service layer can be re-covered through the code engineering scaffolding. It is only necessary to modify the code of the implementation layer according to the new code of the business service layer to meet the business model in the new business scenario, and the target source code that meets the business model is efficiently generated, while further improving the flexibility of target source code generation.

[0072] Step 305: Encapsulate the code of the implementation layer into the initial source code.

[0073] In addition, it should be noted that in order to separate the implementation layer and the business service layer at the level, when encapsulating the code of the implementation layer into the initial source code, the implementation layer and the microservice architecture are respectively encapsulated into the initial source code.

[0074] Step 306 , encapsulate the business service level code and service configuration files in the microservice architecture into the initial source code to determine an executable target source code for satisfying the target business model.

[0075] It should be noted that the execution process of steps 301 to 303 and step 306 can be implemented in any manner in the embodiments of the present disclosure, and the embodiments of the present disclosure do not limit this and will not be described in detail.

[0076] In order to enable the business service layer code and the implementation layer code in the microservice architecture to be fully executed when a request instruction to execute the target source code is received, as a possible implementation method, the microservice architecture is started, and a service configuration file in a first set format and a service configuration file in a second set format are loaded to execute the business service layer code and the implementation layer code.

[0077] As an example, in response to a request instruction to execute a target source code, a microservice architecture is started; when the microservice architecture is started, a service configuration file in a first set format and a service configuration file in a second set format are loaded; according to the service configuration file in the second set format, the code of the domain layer and the code of the permanent layer are executed; according to the service configuration file in the first set format, the code of the interface layer and the code of the application layer are executed; and the code of the implementation layer is executed.

[0078] In summary, by generating implementation classes for the interface layer, application layer and domain layer according to the code of the business service layer in the microservice architecture, and generating the code of the implementation layer according to the implementation class, the code of the implementation layer is encapsulated into the initial source code, thereby separating the code of the business service layer from the code of the implementation layer in the code architecture, and the code of the business service layer is generated through the code engineering scaffolding. When the target source code is migrated to a new business scenario, the code of the business service layer can be re-covered through the code engineering scaffolding. It is only necessary to modify the code of the implementation layer according to the new business service layer code to meet the business model in the new business scenario, thereby achieving efficient generation of the target source code that meets the business model, and further improving the flexibility of target source code generation.

[0079] In order to clearly explain how to modify the first target source code when migrating the target source code to a new business scenario in the above embodiment to meet the business model in the new business scenario, the present disclosure proposes another code generation method.

[0080] Figure 4 It is a flowchart of the code generation method shown in the fourth embodiment of the present disclosure.

[0081] like Figure 4 As shown, the code generation method includes the following steps:

[0082] Step 401: Obtain a first business model in a first business scenario.

[0083] Step 402 : Based on the first business model, a first initial source code and a first code at the business service level in the microservice architecture are generated through a preset code engineering scaffold.

[0084] It should be understood that, when generating the first target source code, the code of the business service layer and the code of the implementation layer in the microservice architecture are separated and encapsulated into the first target source code. Therefore, when migrating the first target source code to a new business scenario, only the code of the implementation layer needs to be modified to meet the business model in the new business scenario, further improving the flexibility of generating source code based on the business model.

[0085] Step 403: Generate a first service configuration file associated with the first code at the business service level according to the first code at the business service level in the microservice architecture.

[0086] The first service configuration file is used to represent the file loaded when executing the first code of the business service level in the microservice architecture.

[0087] Step 404 , encapsulate the first code of the business service level in the microservice architecture and the first service configuration file into the first initial source code to determine an executable first target source code for satisfying the first business model.

[0088] Step 405: if the first target source code is migrated to the second business scenario, the first target source code is modified to determine an executable second target source code for satisfying a second business model in the second business scenario.

[0089] In order to make the modified first target source code meet the second business model under the second business scenario, as a possible implementation method, the first code of the business service layer in the first target source code is overwritten by a pre-set code engineering scaffolding, and the code of the implementation layer is modified to complete the modification of the first target source code.

[0090] As an example, a second business model under a second business scenario is obtained; based on the second business model, a second initial source code and a second code at the business service level in a microservice architecture are generated through a pre-set code engineering scaffold; according to the newly generated second code at the business service level in the microservice architecture, the first code at the business service level in the first target source code is overwritten to determine the second code at the business service level in the first target source code; according to the second code at the business service level in the first target source code, a second service configuration file associated with the second code at the business service level is generated; the first service configuration file in the first target source code is modified into a second service configuration file to complete the modification of the first target source code, and the modified first target source code is used as the second target source code.

[0091] In addition, it should be noted that the first code of the business service level is not the same as the second code of the business service level, and the first service configuration file is not the same as the second service configuration file.

[0092] It should be noted that the execution process of steps 401 to 405 can be implemented in any manner in the embodiments of the present disclosure, and the embodiments of the present disclosure do not limit this and will not be described in detail.

[0093] In summary, a first business model in a first business scenario is obtained, and based on the first business model, a first initial source code and a first code at the business service level in a microservice architecture are generated through a pre-set code engineering scaffolding. According to the first code at the business service level in the microservice architecture, a first service configuration file associated with the first code at the business service level is generated, and the first code at the business service level in the microservice architecture and the first service configuration file are encapsulated into the first initial source code to determine an executable first target source code for satisfying the first business model. If the first target source code is migrated to a second business scenario, the first target source code is modified to determine an executable second target source code for satisfying the second business model in the second business scenario. Thus, not only the business needs in the target business scenario are met, but also when the target business scenario changes, the corresponding code can be generated through the pre-set code engineering scaffolding to adapt to the new business needs in the changed target business scenario, thereby avoiding a large amount of complex and repetitive code coding work and improving the efficiency of converting business models into codes.

[0094] For example, the framework diagram corresponding to the mapping relationship between the business model contained in the code engineering scaffold and the microservice architecture can be as follows: Figure 5As shown, it is assumed that the target business model is a financial business model, wherein there is a mapping relationship between the second data (product function, business function and service function) contained in the product model and the interface layer, there is a mapping relationship between the product model and the application layer (application service), there is a mapping relationship between the data (steps) contained in the process model and the domain layer (domain service), and there is a mapping relationship between the data model and the domain layer (domain model).

[0095] As an example, based on the first data (basic products, business capabilities and ancillary services) contained in the product model, a code conversion tool is used to generate initial source code; according to the mapping relationship between the second data (product functions, business functions and service functions) contained in the product model and the interface layer, the second data (product functions, business functions and service functions) contained in the product model is mapped to the interface layer, and the code of the interface layer is generated by the code conversion tool; and according to the mapping relationship between the product model and the application layer (application service), the second data contained in the product model is mapped to the application layer, and the code of the application layer is generated by the code conversion tool; according to the data (steps) contained in the process model The mapping relationship between the data model and the domain layer (domain service) is used to map the data (steps) contained in the process model to the domain layer (domain service), and the code of the domain layer (domain service) is generated through a code conversion tool. According to the mapping relationship between the data model and the domain layer (domain model), the business object entities contained in the data model are mapped to the domain layer (domain model), and the code of the domain layer (domain model) is generated through a code conversion tool to determine the code of the domain layer; the code of the domain layer is deduced to determine the code of the permanent layer; according to the code of the interface layer, the code of the application layer, the code of the domain layer and the code of the permanent layer, the code of the business service level in the microservice architecture is determined.

[0096] In addition, it should be noted that if the business function or service function is saved in a service configuration file in json format, the service configuration file in json format can be directly loaded and run when starting the microservice architecture.

[0097] In addition, it should be noted that business activities are saved in XML format, so when starting the microservice architecture, the service configuration file in XML format can be directly loaded and run.

[0098] In addition, it should be noted that the process engine is used to parse the service configuration file when starting the microservice architecture.

[0099] In addition, it should be noted that Figure 5The financial business model is divided into three categories: product model, process model, and data model. The product model includes basic products, business capabilities, ancillary services, product functions, business functions, and service functions. Basic products are a group of financial saleable products with similar product functions and business processing rules. Business capabilities are a group of business objects associated together according to certain specific rules and a closed set of multiple logical processing of these business objects. Ancillary services are a group of service functions attached to financial saleable products, with similar service functions and business processing rules. Product functions are the necessary functions of products that can be provided to customers independently, for example, account opening, account closing, deposit and withdrawal of deposit products. Business functions are non-product functions that can be provided to customers independently, for example, adding new customers, accumulating customer limits, updating account status, and stopping / unstopping accounts. Service functions are optional functions attached to products that can be provided to customers independently, for example, distributing media, changing passwords, and changing authentication methods of deposit products.

[0100] In addition, it should be noted that the process model includes business activities, tasks and processes. Business activities are triggered by business events and include a series of tasks. Through the arrangement of tasks, end-to-end operations in different scenarios can be met. Tasks are operations that roles complete to create or update specified business entities during the execution of business activities. Steps are the most granular description of the process model, including business rules and business information.

[0101] In addition, it should be noted that the data model includes business objects and entities. Business objects are a set of highly cohesive and loosely coupled business entities, which are composed of basic entities and all their subordinate attribute entities and relationship entities. Entities are derived from business information needs. They are abstract or concrete things managed and maintained by business needs. They are the basic data concepts for storing business information.
