java 根据表名自动生成增,删,改,查程序代码, 包括Dao接口类,Dao实现类(一)

由于长期写代码, 所以在很多工具之前, 就写了自己的代码生成器.

前面的文章讲了生成 java bean 这个更直接 一把全部生成5个文件

比如 INTERFACE_ID_MAPPING 表生成:

InterfaceIdMapping.java 文件

IInterfaceIdMappingService.java 服务层接口

InterfaceIdMappingServicePojoImpl 服务层接口实现

IInterfaceIdMappingDao.java 层接口

InterfaceIdMappingDaoJdbcImpl 层接口实现

有些人问为什么要生成这么多层?  Service层主要是用来发布微服务,与dao层隔离, dao层有些内容不方便公开.

所以 Service层与 dao层是有必要的 (现在很多开源工具也能做到这点, 但是有些事件还是自己做行靠谱)

 

先来看工具代码

代码太长了, 生成的类由看下一节

关于数据源的问题, 请自己处理, 这个不是核心代码.
