Exception in thread "main" org.apache.ibatis.binding.BindingException: Type interface com.yihaomen.mybatis.inter.IUserOperation is not known to the MapperRegistry.
at org.apache.ibatis.binding.MapperRegistry.getMapper(MapperRegistry.java:21)

at org.apache.ibatis.session.defaults.DefaultSqlSession.getMapper(DefaultSqlSession.java:180)
at com.yihaomen.test.Test.main(Test.java:33)
原因：User.xml 文件中 mapper中：错误如下红色字体为错误命名空间，接口编程中应对应接口所在路径 ，绿色为正确配置。
