Springboot 集成Mybatisz自动化报错：XML fragments parsed from previous mappers already contains value for com.onepoint.ams.dao.mapper.***.Example_Where_Clause

== SpringBoot集成Mybatis自动化生成pojo和*.Mapper.xml过程中重复操作，造成mapper.xml中内容重复，造成该错误；在mapper.xml中查询#id=“Example_Where_Clause”#可发现存在多处，且重复的内容不止此一处；类似的错误还有：Result Maps collection already contains value for com.onepoint.ams.dao.mapper.EnumManagerMapper.BaseResultMap ，都是同一个原因造成的。 ==

** 下面贴下具体的报错如下 **
