org.hibernate.HibernateException: 'hibernate.dialect' must be set when no Connection avalable

今天早上一来一运行程序就报了上面的错误，昨天还好好的。查了半天问题，大多都是说conf.buildSessionFactory();改
conf.configure().buildSessionFactory();不过我的不是读取hibernate.cfg.郁闷中。后来连了下数据库，发现服务器不知道让谁给关了，

这个火大。服务器启动，数据库能正常连接，一切ok。连接不到数据库好像也会报这个错误，暂时不知道为什么。
