解决方案
你service自己编写测试成功了是吧？
List users = us.findAllUser();在这里加人断点，看看us是否真的实例化了。同时可以验证是否真的拦截了
解决方案二：
在daoImpl中的类中,有:
private static final Log logger = LogFactory.getLog(UserDaoHibernateImpl.class);
相应方法中有:
logger.info("dao update");
控制台可以打印这条信息.
所以担心是事务没有配置好.
controller中的相应方法中也打印了浏览器发来的信息.
解决方案三：
service测试成功了，而control报错，应该就是对象创建实例化某个地方出问题了！
