Design And Implementation Of Java Back-End Code Generator Based On SSM Framework

The development of Java Web applications in the enterprise is becoming more and more frequent.In order to reduce repetitive work and speed up front-end development,front-end frameworks such as Vue,React,and Angular provide abundant scaffolding for front-end developers.Popular back-end frameworks such as SSM(Spring + Spring MVC + Mybatis)also greatly simplify back-end development and successfully layer Web applications,and the code at the same level has some similarities,which is very beneficial for automatic code generation,using code generator to automatically generate back-end code can greatly improve the efficiency of back-end development.This paper takes the design and implementation of Java back-end code generator based on SSM framework as the subject,and studies how to use code generation technology to realize the automatic generation of back-end code,so as to save the company back-end development costs.Before development,the common code generation techniques are studied.Then,from the perspective of back-end developers,the requirements of the back-end code generator were investigated and analyzed,and the main functions of the back-end code generator were designed in detail,which include: generating code of data access layer and business layer,generating database table SQL according to the database table;generating the control layer code according to the front and rear functional interface table;generating the role permission setting SQL from the role permission details table.All of the above forms are part of the code generator and are formatted to be filled in by the user based on the actual situation of the project being developed.Finally,a code generation model based on template is designed,and each functional module is coded according to this model.Finally,the design and implementation of Java back-end code generator based on SSM framework is completed.The Java back-end code generator based on SSM framework realizes the direct transformation from project design documents to back-end code,which improves the code quality while shortening the project cycle.The entire code generator is compact and lightweight,requiring only the introduction of related jars or the addition of related dependencies.Users only need to extend part of the generated code according to the business to be copied directly into the project for use,which is ideal for back-end developers.
