实体类：

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

import org.hibernate.annotations.GenericGenerator;


@Entity
@Table(name="T_USER")

	@Id
	@GeneratedValue(strategy=GenerationType.AUTO)

	public String getAge() {

持久层dao接口：

package com.springmvc.dao;

import java.util.List;

import com.springmvc.entity.User;

public interface  UserDao {
      public User getUser(Integer id);
      public List<User> getAllUser();
      public void addUser(User user);
      public boolean delUser(Integer id);
      public boolean updateUser(User user);
}

dao实现类：

package com.springmvc.dao;

import java.util.List;

import org.hibernate.Query;
import org.hibernate.SessionFactory;

import com.springmvc.entity.User;

public class UserDaoImpl implements UserDao {

	private SessionFactory sessionFactory;
	
	
	public void setSessionFactory(SessionFactory sessionFactory) {

	    query.setInteger(2, user.getId());
	    //query.setString(2, user.getId());
	   return (query.executeUpdate()>0);
	}

}

service业务层接口:

package com.springmvc.service;

import java.util.List;

import com.springmvc.entity.User;

public interface UserManager {
      public User getUser(Integer id);
      public List<User> getAllUser();
      public void addUser(User user);
      public boolean delUser(Integer id);
      public boolean updateUser(User user);
}

service层实现类：

package com.springmvc.service;

import java.util.List;

import com.springmvc.dao.UserDao;
import com.springmvc.entity.User;

public class UserManagerImpl implements UserManager {

	private UserDao userDao;
	
	public void setUserDao(UserDao userDao) {
		this.userDao = userDao;
	}

	public void addUser(User user) {
		userDao.addUser(user);
	}

	@Override
	public boolean delUser(Integer id) {
		
		return userDao.delUser(id);
	}

	@Override
	public List<User> getAllUser() {
		
		return userDao.getAllUser();
	}

	@Override
	public User getUser(Integer id) {
		return userDao.getUser(id);
	}

	@Override
	public boolean updateUser(User user) {
		
		return userDao.updateUser(user);
	}

}

controller控制层：

package com.springmvc.controller;

import java.io.IOException;
import java.io.PrintWriter;

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

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import com.springmvc.entity.User;
import com.springmvc.service.UserManager;


@Controller
