刚安装的mysql，在项目运行时出现

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

信息如下：

然后打开sql文件中的mysql.exe也是闪退，在小黑框中打开mysql，也报错误：“Access denied for user 'ODBC'@'localhost' (using password:NO)”
网上搜了一下解决方案：

在Mysql目录下my.ini文件中，最后一行添加“skip-grant-tables”，保存并关闭文件。

重启mysql服务，再执行。

问题解决！
