SpringBoot集成Mybatis-plus并实现自动生成相关文件的示例代码怎么写

这篇文章给大家介绍SpringBoot集成mybatis-plus并实现自动生成相关文件的示例代码怎么写，内容非常详细，感兴趣的小伙伴们可以参考借鉴，希望对大家能有所帮助。

Mybatis-Plus是一个优秀的Mybatis增强工具，目前更新到3.1.1。Mybatis-Plus原生提供了很多单表操作的方法，极大简化了繁琐的curd的操作，同时又支持xml配置、自定义sql的编写。这篇文章介绍springBoot2集成Mybatis-Plus 3.1.0，同时介绍mybatis提供MysqlGenerator.java，你可以通过指定的数据库表生成对应的bean、mapper.xml、mapper.java、service.java、serviceImpl.java，甚至controller

pom.xml添加相关依赖，请注意版本号：
