启动后报这个错误 谁能告诉我为什么啊？

问题解答：

org.hibernate.util.JDBCExceptionReporter] - Cannot create PoolableConnectionFactory (Access denied for user 'root'@'localhost' (using password: YES))
楼主，这个错误很清楚不关Tomcat的事，应该是数据库username和password没有写对（或者是hibernate配置的用户名和密码没有写对的缘故）用户名是root，密码要写正确。

MS是数据源配置问题,建议不要用自带的Tomcat,用自己另外装的吧..

还是自己另外安装一个Tomcat,这样比较好

建议单独装一个Tomcat
