Error creating bean with name 'sqlSessionFactory' defined in class path resource [spring-mybatis.xm

今天在使用反向生成数据库的时候，连续运行了两次方法。刷新之后得到的mapper和pojo文件，利用它进行一系列操作最后得到：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘sqlSessionFactory’ defined in class path resource [spring-mybatis.xml]: Invocation of init method failed; nested exception is org.springframework.core.NestedIOException: Failed to parse mapping resource: ‘file [E:\eclipse\fast\target\classes\com\zhiyou100\mapper\ItemsMapper.xml]’; nested exception is org.apache.ibatis.builder.BuilderException: Error parsing Mapper XML. Cause: java.lang.IllegalArgumentException: Result Maps collection already contains value for com.zhiyou100.mapper.ItemsMapper.BaseResultMap

这是生成两次导致的，删除文件重新生成逆向就OK了
