Answer 1

java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES)
明显是你的数据库配置有问题，你的用户名为root，而密码不对，看你项目怎么配置，我不清楚你数据库配置是在hibernate.cfg.xml还是applicationcontext.xml中，把password密码修改成你自己的密码

Answer 2

检查一下以下几个要点：
1、密码是否填对；
2、项目是否包含正确的驱动包；
3、hibernate配置驱动名称是否写对

Answer 3

配置在applicationcontext.xml，还有用了连接池，里面的密码也改好了，用那个密码可以登录数据库，所以密码不会错。连接池是从一朋友那Copy过来的，他的可以连。
