IDE：IntelliJ IDEA Ultimate .3 （我用的是学生版，只要大学邮箱能用就可以的）
报错信息全文附在最后。其中关键的信息就是：
Root Cause
java.sql.SQLException: Access denied for user ‘root’@‘localhost’ (using password: YES)
解决方法
1.首先，如果项目是你下载的，数据库的账户密码一定都要改好。
2.设置Mysql初始化root密码和允许远程访问：
（1）进入mysql数据库
mysql>update user set password=PASSWORD(‘123456’) where User='root';
（2）授权使Mysql被允许远程访问
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;mysql>FLUSH PRIVILEGES;
