SpringMVC集成休眠时出错

Question

我是Spring MVC的新手。当我做一些跟互联网有关的示例时，我在运行时遇到这样的错误，而且我不知道如何解决。我有搜索，但没有答案。请帮助我。谢谢

这是我的控制器，我在互联网上关注，所以我不知道吗？，我的UserServices只有一种方法public int addUser（User user）

package com.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import com.model.User;
import com.services.UserServices;

@Controller
public class HomeController {
    @Autowired
    private UserServices userservices;
    @RequestMapping(value = "/")
    public String showIndex() {
        return "index";
    }

    @RequestMapping(value = "/add")
    public String addUser() {
        User user = new User();
        user.setUsername("nguyen");
        user.setPassword("123");

        int id = userservices.addUser(user);
        if(id != 0) return "success";
        else return "fail";
    }
}

我的UserDaoImpl和我的UserDao也有一种方法是public int insert（User user）

package com.dao;

import javax.transaction.Transactional;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

import com.model.User;
@Repository
@Transactional
public class UserDAOImpl implements UserDAO {
    @Autowired(required = true)
    private SessionFactory sessionFactory;
    public int insert(User user) {
        Session session = sessionFactory.getCurrentSession();
        Long id = (Long) session.save(user);
        return Integer.valueOf(id.toString());
    }

}

和我的UserServicesImpl

package com.services;

import javax.transaction.Transactional;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.dao.UserDAO;
import com.model.User;
@Service
@Transactional
public class UserServicesImpl implements UserServices{
    @Autowired(required = true)
    private UserDAO userdao;
    public int addUser(User user) {

        return userdao.insert(user);
    }

}

这是我的SpringHibernate-servlet.xml
