声明式事务管理时总报异常！用的spring-3.0与hibernate-3.5整合

Question

请各位大虾帮小弟看下，当我把UserDAOImpl.java中的Session s = sessionFactory.getCurrentSession();改为Session s = sessionFactory.openSession();不会报错，但是事务就根本没用上啊！请问是getCurrentSession()在以前的版本上改了么？我在网上搜说把配置文件beans.xml中的<prop key="hibernate.current_session_context_class">thread</prop>的thread改为jta还是不行啊！请大家帮我解决下非常感谢啊！！！

LZ,看下这个，应该对你有帮助http://liusu.javaeye.com/blog/380397

Answer 2

我也遇到这个错误了。哎，原来用spring的hibernateTemplate没有这个错

Answer 3

org.hibernate.HibernateException: save is not valid without active transaction首先明白：SessionFactory.getCurrentSession与openSession的区别
如果使用的是getCurrentSession来创建session的话，在commit后，session就自动被关闭了，
    也就是不用再session.close()了。但是如果使用的是openSession方法创建的session的话，
    那么必须显示的关闭session，也就是调用session.close()方法。这样commit后，session并没有关闭；
如果你用的是SessionFactory.getCurrentSession();你的配置文件没有错，要把<prop key="hibernate.current_session_context_class">thread</prop>加上， 到这步后问题就变得很简单了 在
  public void save(User user) {
    Session s = sessionFactory.getCurrentSession();
     //这里要开启事务
       s.save(user);
  }
  的s.save(user);前加上 session.beginTransaction();
