SpringBoot集成Mybatis-plus並實現自動生成相關文件的示例代碼
Mybatis-Plus是一個優秀的Mybatis增強工具，目前更新到3.1.1。Mybatis-Plus原生提供瞭很多單表操作的方法，極大簡化瞭繁瑣的curd的操作，同時又支持xml配置、自定義sql的編寫。這篇文章介紹SpringBoot2集成Mybatis-Plus 3.1.0，同時介紹mybatis提供MysqlGenerator.java，你可以通過指定的數據庫表生成對應的bean、mapper.xml、mapper.java、service.java、serviceImpl.java，甚至controller
