声明式事务管理时总报异常！用的spring-3.0与hibernate-3.5整合
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！！！
用Junit测试时的出错信息如下：
