hibernate5.x版本hello world

Configurationconfig =newConfiguration().configure("hibernate.cfg.xml");

 ServiceRegistry  serviceRegistry=newStandardServiceRegistryBuilder()

                              .applySettings(config.getProperties()).build();

SessionFactory  sessionFactory= config.addClass(News.class).addClass(User.class)

                               .buildSessionFactory(serviceRegistry);

Session session=sessionFactory.openSession();

Transaction transaction=session.beginTransaction();

一定要记得调用 addClass方法指明所要操作的实体class对象
