org.apache.ibatis.exceptions.PersistenceException

今天在学习当中遇到以下错误:org.apache.ibatis.exceptions.PersistenceException: ### Error getting a new connection. Cause: java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES)### Cause: java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES)

PersistenceException表示持久性异常，关于数据库层的错误。

同时还有：Access denied for user ‘root’@‘localhost’ (using password: YES)

后经过我检查发现是密码写错了。
