连接mysql被拒绝连接Access denied for user
idea连接mysql报错：[28000][1045] Access denied for user ‘root’@‘localhost’ (using password:YES)导致错误的原因，无论using password后的是yes还是no，都是因为密码不正确，区别如下：
[28000][1045] Access denied for user ‘root’@‘localhost’ (using password: NO) 没有填写密码
Access denied for user ‘root’@‘localhost’ (using password: YES) 填写了密码，但密码是错误的
