介绍

Mybatis training, such as common operation, paging, Mybatis Plus, generator etc.

核心模块

• mybatis-generator

基于mybatis-generator实现根据数据库表自动生成对应的Entity、Mapper、Service、ServiceImpl、Controller、映射文件，通过自定义CommentGenerator以及PluginAdapter自动生成Java文件的版权信息、类注释、属性注释、方法注释等。

• mybatis-plus-generator

基于mybatis-plus-generator实现根据数据库表自动生成对应的Entity、Mapper、Service、ServiceImpl、Controller等，支持通过配置文件定制多个模块的代码生成策略。配置类参考MpGeneratorConfig，配置文件参考generatorConfig.yml，示例如下：
