SpringMVC+hibernate获取数据报错??

想使用hibernate来获取数据库里的数据,但是浏览器访问的时候 就报错了.
eclipse没有提示语法错误,但是控制台报错了.
MvcController.java

package qiye.web;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;

import qiye.entity.Service;

@Controller
public class MvcController {
    private static SessionFactory sessionFactory;
    static{
        Configuration configuraction = new Configuration().configure();
        sessionFactory = configuraction.buildSessionFactory();
    }
    public static Session getSession(){
        return sessionFactory.openSession();
    }
    
    
    @RequestMapping("/index")
    public String index(){
        
        Session session = MvcController.getSession();
        Service service = (Service)session.get(Service.class, new Integer(1));
        System.out.println(service.getTitle());
        
        return "index";
    }
    
}

控制台的错误信息

这个用法有错误，hibernate 是对dao层进行操作，service是操作业务逻辑代码，controller是空气器，这是要明确分工，下面是个简单的小demo //新建UserDao package com.purchase.dao; import com.purchase.domain.User; public interface UserDao { public void addUser(User user); } //新建实现类UserDaoImpl public class UserDaoImpl implements UserDao{ private SessionFactory sessionFactory; public void setSessionFactory(SessionFactory sessionFactory) { this.sessionFactory = sessionFactory; } @Override public void addUser(User user) {//添加用户 sessionFactory.getCurrentSession().save(user); } } //新建service类 public interface UserService { public void addUser(User user); } //新建service实现类 public class UserServiceImpl implements UserService { public UserDao userDao; @Override public void addUser(User user) { userDao = new UserDaoImpl(); userDao.addUser(user); } } //新建controller控制类 @Controller @RequestMapping("/user") public class UserController { @Resource(name="userService")// 获取spring配置文件中bean的id为userService的，并注入 private UserService userService; @RequestMapping("/addUser")// 请求url地址映射，类似Struts的action-mapping public String addUser(User user){ userService.addUser(user); return "redirect:/user/success"; } }
