package com.dajiu.bean;
/**
* Created by zhangxing on 2017/4/7.
*/
public class User {
private int id;
private String name;
private String password;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
②然后再dao中定义UserDao接口
package com.dajiu.dao;
import com.dajiu.bean.User;
import org.apache.ibatis.annotations.Param;
import org.springframework.stereotype.Repository;
import java.util.List;
/**
* Created by zhangxing on 2017/4/7.
*/
@Repository
public interface UserDao {
List getAll();
User getLogin(@Param("name") String name, @Param("password") String password);
}
在user.xml中映射dao层
③接着在service中申明接口
package com.dajiu.service;
import com.dajiu.bean.User;
import java.util.List;
/**
* Created by zhangxing on 2017/4/7.
*/
public interface UserService {
List getAll();
User getLogin(String name,String password);
}
④再在service.impl中具体实现接口逻辑
package com.dajiu.service.impl;
import com.dajiu.bean.User;
import com.dajiu.dao.UserDao;
import com.dajiu.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
/**
* Created by zhangxing on 2017/4/7.
*/
@Service("UserService")
public class UserServiceImpl implements UserService {
@Autowired
UserDao userDao;
public List getAll() {
return userDao.getAll();
}
public User getLogin(String name, String password) {
return userDao.getLogin(name,password);
}
}
这里的@Autowired相当于新建一个实例
⑤在controller中实现真正的后台调用逻辑
package com.dajiu.controller;
import com.dajiu.bean.User;
import com.dajiu.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
/**
* Created by zhangxing on 2017/4/7.
*/
@Controller
@RequestMapping("/blog")
public class UserController {
@Autowired
UserService userService;
@RequestMapping("/getUser")
@ResponseBody
public Map getUser(){
Map map = new HashMap();
List list = userService.getAll();
map.put("user",list);
map.put("status",1);
map.put("success",true);
return map;
}
@RequestMapping("getLogin")
@ResponseBody
public Map getLogin(String name,String password){
Map map = new HashMap();
User user = userService.getLogin(name,password);
map.put("user",user);
map.put("isLogin",true);
map.put("status",1);
return map;
}
}
