회원(3) - 비밀번호 변경

지금까지 회원가입과 로그인 기능을 구현했는데요

 

이제 사용자의 비밀번호를 변경하는 기능을 구현해보도록 하겠습니다.

 

1. userMapper

 

<?xml version="1.0" encoding="UTF-8"?>

<!-- DTD 선언 -->
<!DOCTYPE mapper
	PUBLIC "-//mybatis.org/DTD Mapper 3.0//EN"
	"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
	
<mapper namespace="userMapper">
	
   <insert id="register">
   		insert into user(identification, password, name)
   		values( #{identification}, #{password}, #{name})
   </insert>
   
   <select id="login" resultType="UserVO">
   		select identification, name, password
   		from user
   		where identification = #{identification} and password = #{password}
   </select>
   
   <update id="modify">
   		update user
   		set password = #{password}
   		where identification = #{identification}
   </update>
    	
</mapper>

 

비밀번호를 변경하는 조건으로 아이디를 사용했습니다.

 

2. UserDAO 작성

 

package kr.co.web.persistence;

import kr.co.web.domain.UserVO;

public interface UserDAO {

	public void register(UserVO vo) throws Exception;
	public UserVO login(UserVO vo) throws Exception;
	public void modify(UserVO vo) throws Exception;
}

 

package kr.co.web.persistence;

import javax.inject.Inject;

import org.apache.ibatis.session.SqlSession;
import org.springframework.stereotype.Repository;

import kr.co.web.domain.UserVO;

@Repository
public class UserDAOImpl implements UserDAO{
	
	@Inject
	private SqlSession session;
	
	private static final String NS = "userMapper";
	private static final String REGISTER = NS + ".register";
	private static final String LOGIN = NS + ".login";
	private static final String MODIFY = NS + ".modify";
	
	@Override
	public void register(UserVO vo) throws Exception {
		session.insert(REGISTER, vo);
	}
	
	@Override
	public UserVO login(UserVO vo) throws Exception {
		return session.selectOne(LOGIN, vo);
	}
	
	@Override
	public void modify(UserVO vo) throws Exception {
		session.update(MODIFY, vo);
	}

}

 

 

3. SERVICE 작성

 

package kr.co.web.service;

import kr.co.web.domain.UserVO;

public interface UserService {

	public void register(UserVO vo) throws Exception;
	public UserVO login(UserVO vo) throws Exception;
	public void modify(UserVO vo) throws Exception;
}

 

package kr.co.web.service;

import javax.inject.Inject;

import org.springframework.stereotype.Service;

import kr.co.web.domain.UserVO;
import kr.co.web.persistence.UserDAO;

@Service
public class UserServiceImpl implements UserService {
	
	@Inject
	private UserDAO user;
	
	@Override
	public void register(UserVO vo) throws Exception {
		user.register(vo);
	}
	
	@Override
	public UserVO login(UserVO vo) throws Exception {
		return user.login(vo);
	}
	
	@Override
	public void modify(UserVO vo) throws Exception {
		user.modify(vo);
	}
	
}

 

 

4. Controller 작성

 

package kr.co.web.controller;

import javax.inject.Inject;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.mvc.support.RedirectAttributes;

import kr.co.web.domain.UserVO;
import kr.co.web.service.UserService;

@Controller
@RequestMapping("/user/*")
public class UserController {

	@Inject
	private UserService service;
	
	private static final Logger logger = LoggerFactory.getLogger(UserController.class);
	
	@RequestMapping(value = "/register", method = RequestMethod.GET)
	public void registerGET() throws Exception {
		logger.info("registerGET");
	}
	
	@RequestMapping(value = "/register", method = RequestMethod.POST)
	public String registerPOST(UserVO vo, RedirectAttributes ra) throws Exception {
		logger.info("registerPOST");
		service.register(vo);
		ra.addFlashAttribute("result", "registerOK");
		
		return "redirect:/";
	}
	
	@RequestMapping(value = "/login", method = RequestMethod.POST)
	public String loginPOST(UserVO vo, HttpServletRequest req, RedirectAttributes ra) throws Exception {
		logger.info("post login");
		
		// HttpServletRequest를 사용하면 값을 받아 올수 있다.
		HttpSession session = req.getSession();
		
		UserVO login = service.login(vo);
		
		if(login == null) {
			session.setAttribute("user", null);
			ra.addFlashAttribute("result", "loginFalse");
		} else {
			session.setAttribute("user", login);
			String id = req.getParameter("identification"); // 확인용
			ra.addFlashAttribute("result", "loginOK");
		}
		return "redirect:/";
	}
	
	@RequestMapping(value ="/logout", method = RequestMethod.GET)
	public String logout(HttpSession session) throws Exception {
		logger.info("logout");
		session.invalidate();
		return "redirect:/";
	}
	
	@RequestMapping(value ="/modify", method = RequestMethod.GET)
	public void modifyGET() throws Exception {
		logger.info("modifyGET");
	}
	
	@RequestMapping(value ="/modify", method = RequestMethod.POST)
	public String modifyPOST(HttpSession session, UserVO vo, RedirectAttributes ra) throws Exception {
		logger.info("modifyPOST");		
		service.modify(vo);
		session.invalidate();
		ra.addFlashAttribute("result", "updateOK");
		return "redirect:/";
	}
	
}

 

5. modify.jsp 생성

 

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<html>
<head>
 <title>게시판</title> 
 
</head>
<body>

<form method="post" autocomplete="off">
 	
 	<div>
 		<label for="identification">아이디</label>
 		<input type="text" id="identification" name="identification" value="${user.identification}" readonly/>
 	</div>
 	
 	<div>
 		<label for="password">새 비밀번호</label>
 		<input type="password" id="password" name="password" />
 	</div>
 	
 	<div>
 		<button type="submit">회원정보 수정</button>
 	</div>
 	
</form>

	<div>
		<button onclick ="location.href='/'">처음</button>
	</div>
</body>
</html>

 

뭔가 익숙하지 않나요?

회원가입할 때 작성했던 코드와 비슷한데요.

저희는 회원변경을 할것이기 때문에 

아이디부분에 아까 세션 "user"로 보낸것을 

아이디부분에 넣어주고 변경할 수 없도록 readonly를 적어주었습니다.

 

이제 home.jsp로 돌아가서 로그인을 했을 때 회원정보 수정이 있어야 하기에

추가해주도록 합니다.

 

<button type="button" onclick="location.href='/user/modify'">회원정보 수정</button>

 

 

 

비밀번호를 aaas 로 변경하겠습니다.

 

 

 

 

정상적으로 변경되었습니다.
