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

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:
