你用的是Hibernate5.0及以上版本，不需要ServiceRegistry了，视频老师用的是4.X版本的Hibernate。

将代码改为下面的就可以了

@Before
   public void init()
   {
       /*
       * hibernate 5.0以上版本，不通过ServiceRegistry
       */
       //创建配置对象
       Configuration configuration=new Configuration().configure();
       //创建会话工厂对象
       sessionFactory = configuration.buildSessionFactory();
       //创建会话对象
       session=sessionFactory.openSession();
       //开启事务
       transation= session.beginTransaction();
   }

我也是出现这个问题，后来在评论区找到的答案，框架学起来有点吃力啊！！！
