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

可能由于root的权限不够，可以进行如下操作

1)      以root进入mysql

2)      赋予root权限：

（在mysql   Command Line Client中输入以下命令）

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost'
->     IDENTIFIED BY 'some_pass' WITH GRANT OPTION; 
//本地操作的权限
mysql> GRANTALL PRIVILEGES ON *.* TO ' root '@'%'
->     IDENTIFIEDBY 'some_pass' WITH GRANT OPTION;
                    //远程操作的权限

例如：

create database OTHERWebPlatform;

grant all on OTHERWebPlatform.* to lucy@localhost identified by '142857';
//设置字符类型

ALTER DATABASE `OTHERWebPlatform` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
