测试：
到这里，环境基本搭建完成了，写代码测试一下
首先看看代码的结构图

数据库表设计

为了方便测试环境框架就建立了一个简简单单的实体类
dao层代码

package com.tgb.dao;import java.util.List;import com.tgb.entity.User;public interface IUserDao {public User getUser(String id);public List<User> getAllUser();public void addUser(User user);public boolean delUser(String id);public boolean updateUser(User user);
}

dao实现类

package com.tgb.dao;import java.util.List;import javax.annotation.Resource;import org.hibernate.Query;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;import com.tgb.base.BaseDao;
import com.tgb.entity.User;
@Repository
public class UserDao implements IUserDao {@Autowiredprivate SessionFactory sessionFactory;@Resourceprivate BaseDao<User> baseDao;public void setSessionFactory(SessionFactory sessionFactory) {this.sessionFactory = sessionFactory;}@Overridepublic User getUser(String id) {String hql = "from User u where u.id=?";Query query = sessionFactory.getCurrentSession().createQuery(hql);query.setString(0, id);return (User)query.uniqueResult();}@Override
public List<User> getAllUser() {String hql = "from User";//baseDao.find(hql);//Query query = sessionFactory.getCurrentSession().createQuery(hql);return baseDao.find(hql);}@Overridepublic void addUser(User user) {sessionFactory.getCurrentSession().save(user);}@Overridepublic boolean delUser(String id) {String hql = "delete User u where u.id = ?";Query query = sessionFactory.getCurrentSession().createQuery(hql);query.setString(0, id);return (query.executeUpdate() > 0);}@Overridepublic boolean updateUser(User user) {String hql = "update User u set u.userName = ?,u.age=? where u.id = ?";
Query query = sessionFactory.getCurrentSession().createQuery(hql);query.setString(0, user.getUserName());query.setString(1, user.getAge());query.setString(2, user.getId());return (query.executeUpdate() > 0);}}

service层方法

package com.tgb.service;import java.util.List;import com.tgb.entity.User;public interface IUserService {public User getUser(String id);public List<User> getAllUser();public void addUser(User user);public boolean delUser(String id);public boolean updateUser(User user);}
AI写代码1234567891011121314151617181920

service实现类

package com.tgb.service;import java.util.List;import javax.annotation.Resource;import org.springframework.stereotype.Service;import com.tgb.dao.IUserDao;
import com.tgb.entity.User;
@Service
public class UserService implements IUserService {@Resourceprivate IUserDao userDao;public void setUserDao(IUserDao userDao) {this.userDao = userDao;}@Overridepublic User getUser(String id) {return userDao.getUser(id);}@Overridepublic List<User> getAllUser() {return userDao.getAllUser();}@Overridepublic void addUser(User user) {userDao.addUser(user);}@Overridepublic boolean delUser(String id) {return userDao.delUser(id);}@Override
public boolean updateUser(User user) {return userDao.updateUser(user);}}

controller层

package com.tgb.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.web.bind.annotation.RequestMapping;import com.tgb.entity.User;
import com.tgb.service.IUserService;@Controller
@RequestMapping("/user")
public class UserController {@Resourceprivate IUserService userService;@RequestMapping("/getAllUser")
public String getAllUser(HttpServletRequest request){request.setAttribute("userList", userService.getAllUser());return "/index";}@RequestMapping("/getUser")public String getUser(String id,HttpServletRequest request){request.setAttribute("user", userService.getUser(id));return "/editUser";}@RequestMapping("/toAddUser")public String toAddUser(){return "/addUser";}@RequestMapping("/addUser")public String addUser(User user,HttpServletRequest request){userService.addUser(user);return "redirect:/user/getAllUser";}@RequestMapping("/delUser")public void delUser(String id,HttpServletResponse response){String result = "{\"result\":\"error\"}";
if(userService.delUser(id)){result = "{\"result\":\"success\"}";}response.setContentType("application/json");try {PrintWriter out = response.getWriter();out.write(result);} catch (IOException e) {e.printStackTrace();}}@RequestMapping("/updateUser")public String updateUser(User user,HttpServletRequest request){if(userService.updateUser(user)){user = userService.getUser(user.getId());request.setAttribute("user", user);return "redirect:/user/getAllUser";}else{return "/error";}}
}

看看效果，虽然简单，足以说明问题
