这里是我的项目列表

这是我的控制类的代码

package handlers;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;


import Service.VipService;
import beans.Vip;
@Controller
@RequestMapping("/index")
public class VipController   {
    
    @Autowired
    @Qualifier("VipService")
    
    private VipService service;
    public void setService(VipService service) {
        this.service = service;
    }



    @RequestMapping("/register.do")
    public String doRegister(int phone, String password) throws Exception {    
        Vip vip=new Vip(phone,password);
         service.addVip(vip);      
         return "/welcome.jsp";
        
    }

}

这是我的服务类的代码

package Service;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import beans.Vip;
import dao.VipDao;

//@里内的名字要与控制类vipcontroller内的调用的service名字一样
@Service("VipService")
public class VipServiceImpl implements VipService {
    @Resource(name="VipDao")
    
    private VipDao dao;
    
     
    public void setDao(VipDao dao) {
        this.dao = dao;
    }


    @Transactional
    public void addVip(Vip vip) {
        dao.insertVip(vip);

    }

}

缺少bean vipDao，你这个是没在配置文件配置这个bean,spring没办法帮你注入。
