**IDEA搭建Mybatis入门案例时出现错误：Exception in thread “main” org.apache.ibatis.exceptions.PersistenceException:

Error building SqlSession.

The error may exist in com.itheima.dao.IUserDao.xml

Cause: org.apache.ibatis.builder.BuilderException: Error parsing SQL Mapper Configuration. Cause: java.io.IOException: Could not find resource com.itheima.dao.IUserDao.xml**

可是我已经在SqlMapConfig.xml配置好了IUserDao.xml映射配置文件的全限定性类名的位置

后来改成

就好了
