Mybatis-generator-maven-plugin plug-in extensions add a custom method

After using Mybatis-generator-maven-plugin for code generation, it may be found that some common methods are not generated, such as delete operations, the data in the database is meaningful, delete as far as possible is the logical delete operation, If you use the code generator's Delete method, then the data is physically deleted, this method is not what we need, then we need to add a method Deletelogicbyids in the code generation process, so that all the code generation process, if you can automatically generate this method, then, The amount of code we have is pretty low.


After we created the table structure, the process of generating the code through the MVN command automatically generated one of our custom methods, what a wonderful thing.

First Git:http://git.oschina.net/alexgaoyh/mutimodule-parent.

Which, in the Generatorconfig.xml file, adds

<plugin type= "com. MutiModule.common.mybatis.plugin.PaginationPlugin "></plugin><plugin type=" com. MutiModule.common.mybatis.plugin.DeleteLogicByIdsPlugin "></plugin>
