JavaWeb_(Hibernate框架)使用Hibernate开发用户注册功能

 

 

 

使用Hibernate开发用户注册功能：

　　用户在register.jsp表单成功后，页面跳转到login.html，数据库中会存放用户注册的信息

        //创建sessionFactiory对象
        SessionFactory sessionFactory = config.buildSessionFactory();
        //获取session
        Session session = sessionFactory.openSession();
        
        //打开事务
        Transaction transaction = session.beginTransaction();
        
        //存储User对象
        session.save(user);
        
        //提交事务
        transaction.commit();
