Description:
1. service domain data model base
The business domain data model base in the application uses the business model entity object driving development as a guiding thought, and mainly combines general domain knowledge, enterprise business domain knowledge and the existing application system to analyze and precipitate, so as to form a business domain data model base which is built for the self business development requirement of the enterprise.
As shown in fig. 4 to 7, the model entity object data in the business domain data model library is stored in a database, such as: and the MySql database is used for adding, modifying and deleting entity data for maintaining the service domain data model database in the service domain data model system function by service personnel or technicians. The business model entity object is stored in a database in the form of data table structured information, and mainly comprises a business major class, a business minor class, entity basic information, entity structured attribute, entity relation information, entity version information, entity authorization management, entity reference record, entity text attribute, entity history record and other structured data tables, wherein the entity basic information is the business model entity object.
2. Conversion of MOM object files based on business model entity objects
According to the method, the system and the device, the business model entity object in the business domain data model library is quoted, the business model entity object is converted into the MOM object file, the business model entity object is easy to correct in a model tool, the problem that business and the business model entity object accurately correspond to each other is well solved, the MOM object file information of the method stores a local working space in an XML format, and platform independence and portability of the method are achieved.
1) As shown in fig. 8, first, a local development tool is opened, such as: eclipse, configuring business domain data model base information in attribute configuration, such as: model library address, port, user information, etc.
2) As shown in fig. 9, next, a business domain data model library is opened through a local development tool menu wizard, and among query conditions, query conditions are input, such as: and the personnel basic information is that personnel basic information entity objects are selected in the query result, and introduced into the model tool by clicking the introduction button.
3) As shown in fig. 10, when the introduce button is clicked, basic information entity object information of personnel is obtained through an interface API service of the business domain data model library, and a MOM object file readable or maintainable by a model tool is converted through a business model entity converter.
4) As shown in fig. 11, after the MOM object file is converted, the model tool loads the MOM object file, displays the introduced business model entity object information, and the designer or technician can adjust the model attribute information according to the business requirement, such as adding business attribute or modifying data type.
5) After the business model entity object information is adjusted, the adjusted business model entity object is synchronized to a business domain data model database by calling a business domain data model database interface API service.
6) And storing MOM object file information.
3. MOM object file storage format
As shown in fig. 12 and 13, the whole MOM object file information is stored in an XML structure, and is converted into the XML structure by the business model entity converter for storage in the process of introducing the business model entity object. The XML structure is wholly divided into two parts, wherein the first part is information required by a model tool page, such as version information, basic information, style information and the like, and the second part is introduced business model entity object information, such as a business domain to which a business model entity object belongs, business model entity object attribute information and the like. The MOM object file information and the business model entity object information are in one-to-many relation, and a plurality of business model entity objects can be introduced at a time or a plurality of times according to business needs. The maintenance system of the business domain data model base can be convenient for inputting, expanding and maintaining business model entity object information.
4. Generating micro-service code based on MOM object files

Inputting the converted MOM object file into a source code generator, and sequentially analyzing the MOM object file, selecting page style, binding page attribute and matching a pre-generated technical framework in the source code generator, wherein the technical framework comprises the following steps: and finally outputting the generated micro application or micro service source code structure information by the micro service, wherein the details are as follows:
1) First, in the development tool project catalog, a MOM object file is selected, a right click mouse selects conversion source codes in a menu, and information such as a service name, a service catalog structure and the like is input in a pop-up interface.
2) As shown in fig. 15, next, the source code generator obtains MOM object file information, parses the MOM object file according to XML tag definition, puts the MOM object file into a cache, generates a wizard according to the source code, and selects a service display interface style, such as: a tree structure, a multi-Tab structure, or a list structure, clicking on the next step.
3) As shown in fig. 16, after the interface presentation style is confirmed, binding is performed with the service model entity object attribute extracted by the analysis MOM object file, for example: the user name corresponds to the user_name, and the next step is clicked after the binding is completed.
4) After the business model entity object attribute is bound, matching the source code generation architecture according to project technical architecture requirements, such as: micro services, micro applications, monolithic structures, etc.
5) As shown in fig. 17, the source code structure information is finally output by the source code generator.
And the application code of the micro-service architecture is generated by using the MOM object file converted by the business model entity converter, so that the development efficiency of the micro-service is improved. The code generation engine in the application is based on a template mode, and templates are provided: the micro-service, micro-application and monomer structure provides complete code templates of data access layer, business logic layer, control layer and presentation layer for the developer to select. The developer can choose to generate only the back-end service codes, the codes containing the data access layer and the business logic layer, or generate complete front-end display codes and back-end service codes according to the use scene of the micro-service, wherein the front-end display codes contain the codes of the display layer and the control layer.
