通过注册页面访问RegistAction的regist方法就报上面的错，是不能进行初始化bean,但找了半天没有找到原因，我用测试实例可以将数据存入数据库，没有报错，测试代码如下：
@Test
public void save1(){
ApplicationContext ctx=new ClassPathXmlApplicationContext("beans.xml");
RegistService service=(RegistService)ctx.getBean("r");
User user=new User();
user.setName("YU");
user.setEmail("123");
service.add(user);
service.dayin();
}各位好心的大侠帮帮忙吧！小弟感激不尽啊！
