Spring framework3.2整合hibernate4.1报错：No S?报错

  最近在自己捣鼓这个东西，使用的spring-framework-3.2.0 和 hibernate4.1。

  想自己写个通用dao，结果在getCurrentSession()的时候报错了。但是使用openSession()是正常的。

   请教下各位OSCER，这是什么情况，谢谢。

/**

	@Autowired
	@Qualifier("sessionFactory")  
	private SessionFactory  sessionFactory;
	
	protected Session d(){
		return sessionFactory.getCurrentSession();
	}

   在网上找了很多资料，有的说是要加

<prop key="current_session_context_class">thread</prop>

但是加了也不可以。。。。

在线等各位回答，谢谢！
