报错Cause: java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES)

在搭建mybatis框架调试的时候出现了如下错误：

org.apache.ibatis.exceptions.PersistenceException: 
### Error querying database.  Cause: java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES)
### The error may exist in sqlmap/User.xml
### The error may involve test.findUserById
### The error occurred while executing a query
### Cause: java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES)

 

经过查询发现是config里面的配置文件数据库的密码写错了，修改即可。
