        .buildServiceRegistry();
        //配置我们的SessionFactory
        SessionFactory sf = conf.buildSessionFactory(sr);
        //获取我们的Session
        Session sess = sf.openSession();
        //开始我们的事务
        Transaction tx = sess.beginTransaction();
       
        News n = new News();
        n.setTitle("ITkezhan");
        n.setContent("IT客栈");
       
        //保存持久化对象
        sess.save(n);

        tx.commit();
        //关闭Session
        sess.close();
        //关闭SessionFactory
        sf.close();
