**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
