2. UserRepository 에 findById() 만들기

package shop.mtcoding.blog.user;

import jakarta.persistence.EntityManager;
import jakarta.persistence.Query;
import lombok.RequiredArgsConstructor;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;
import shop.mtcoding.blog.board.Board;

@RequiredArgsConstructor
@Repository
public class UserRepository {

    private final EntityManager em;
    
    public User findById(int id) {
        User user = em.find(User.class, id);
        return user;
    }
    
    @Transactional
    public User save(User user){
        em.persist(user);
        return user;
    }

    public User findByUsernameAndPassword(UserRequest.LoginDTO reqDTO){
        Query query =
                em.createQuery("select u from User u where u.username = :username and u.password =:password", User.class);
        query.setParameter("username", reqDTO.getUsername());
        query.setParameter("password", reqDTO.getPassword());
        return (User) query.getSingleResult();
    }
}
 
  • 단위 테스트
package shop.mtcoding.blog.User;

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.orm.jpa.DataJpaTest;
import org.springframework.context.annotation.Import;
import shop.mtcoding.blog.user.User;
import shop.mtcoding.blog.user.UserRepository;
import shop.mtcoding.blog.user.UserRequest;

@Import(UserRepository.class) // IoC 등록코드
@DataJpaTest // Datasource(connection pool), EntityManager
public class UserRepositoryTest {

    @Autowired // DI
    private UserRepository userRepository;

    @Test
    public void findById_test(){
        // given
        int id = 1;
        // when
        userRepository.findById(id);
        // then
        System.out.println("findById_test : " + id);
    }
    @Test
    public void findByUsername_test(){
        // given
        UserRequest.LoginDTO reqDTO = new UserRequest.LoginDTO();
        reqDTO.setUsername("ssar");
        reqDTO.setPassword("1234");

        // when
        User user = userRepository.findByUsernameAndPassword(reqDTO);

        // then
    }
}

3. UserController 에 updateForm 수정하기

  • session(mypage)에 있으니 URL에 id가 필요 없음
  • User 객체에서 필요한 것만 session에 담음 / User 객체의 모든 정보를 다 담지 않음
  • User 객체를 넣었기 때문에 동기화 해줘야함
  • session의 값이 변동되는 것이 아니라면 DB에 변경만 해주면 됨
package shop.mtcoding.blog.user;

import jakarta.servlet.http.HttpServletRequest;
import jakarta.servlet.http.HttpSession;
import lombok.NoArgsConstructor;
import lombok.RequiredArgsConstructor;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;

@RequiredArgsConstructor
@Controller
public class UserController {

    private final UserRepository userRepository;
    private final HttpSession session;

    @PostMapping("/join")
    public String join(UserRequest.JoinDTO reqDTO) {
        User sessionUser = userRepository.save(reqDTO.toEntity());
        session.setAttribute("sessionUser", sessionUser);
        return "redirect:/";
    }

    @PostMapping("/login")
    public String login(UserRequest.LoginDTO reqDTO) {
        User sessionUser = userRepository.findByUsernameAndPassword(reqDTO);
        session.setAttribute("sessionUser", sessionUser);
        return "redirect:/";
    }

    @GetMapping("/join-form")
    public String joinForm() {
        return "user/join-form";
    }

    @GetMapping("/login-form")
    public String loginForm() {
        return "user/login-form";
    }

    @GetMapping("/user/update-form") // session(mypage)에 있으니 id가 필요 없음
    public String updateForm(HttpServletRequest request) {
        User sessionUser = (User) session.getAttribute("sessionUser");
        User user = userRepository.findById(sessionUser.getId());
        request.setAttribute("user", user);
        return "user/update-form";
    }

    @GetMapping("/logout")
    public String logout() {
        session.invalidate();
        return "redirect:/";
    }
}
 

4. view 수정해서 기존의 데이터 뿌리기

{{> /layout/header}}

<div class="container p-5">

    <!-- 요청을 하면 localhost:8080/join POST로 요청됨
    username=사용자입력값&password=사용자값&email=사용자입력값 -->

    <div class="card">
        <div class="card-header"><b>회원수정을 해주세요</b></div>
        <div class="card-body">
            <form action="/user/update" method="post" enctype="application/x-www-form-urlencoded">
                <div class="mb-3">
                    <input type="text" value="{{user.username}}" class="form-control" placeholder="Enter username" name="username" disabled>
                </div>
                <div class="mb-3">
                    <input type="password" class="form-control" placeholder="Enter password" name="password">
                </div>
                <div class="mb-3">
                    <input type="email" value="{{user.email}}" class="form-control" placeholder="Enter email" name="email" disabled>
                </div>
                <button type="submit" class="btn btn-primary form-control">회원가입수정</button>
            </form>
        </div>
    </div>
</div>

{{> /layout/footer}}

  • 수정할 값만 name값이 있으면 됨
{{> /layout/header}}

<div class="container p-5">

    <!-- 요청을 하면 localhost:8080/join POST로 요청됨
    username=사용자입력값&password=사용자값&email=사용자입력값 -->

    <div class="card">
        <div class="card-header"><b>회원수정을 해주세요</b></div>
        <div class="card-body">
            <form action="/user/update" method="post" enctype="application/x-www-form-urlencoded">
                <div class="mb-3">
                    <input type="text" value="{{user.username}}" class="form-control" placeholder="Enter username" disabled>
                </div>
                <div class="mb-3">
                    <input type="password" class="form-control" placeholder="Enter password" name="password">
                </div>
                <div class="mb-3">
                    <input type="email" value="{{user.email}}" class="form-control" placeholder="Enter email" disabled>
                </div>
                <button type="submit" class="btn btn-primary form-control">회원가입수정</button>
            </form>
        </div>
    </div>
</div>

5. password와 emil 수정하게 변경하기

  • 변경될 값에 name값이 없으면 no key라 에러가 남!!
{{> /layout/header}}

<div class="container p-5">

    <!-- 요청을 하면 localhost:8080/join POST로 요청됨
    username=사용자입력값&password=사용자값&email=사용자입력값 -->

    <div class="card">
        <div class="card-header"><b>회원수정을 해주세요</b></div>
        <div class="card-body">
            <form action="/user/update" method="post" enctype="application/x-www-form-urlencoded">
                <div class="mb-3">
                    <input type="text" value="{{sessionUser.username}}" class="form-control" placeholder="Enter username" disabled>
                </div>
                <div class="mb-3">
                    <input type="password" class="form-control" placeholder="Enter password" name="password">
                </div>
                <div class="mb-3">
                    <input type="email" value="{{sessionUser.email}}" class="form-control" placeholder="Enter email" name="email">
                </div>
                <button type="submit" class="btn btn-primary form-control">회원가입수정</button>
            </form>
        </div>
    </div>
</div>

{{> /layout/footer}}
 

6. UserRepository 에서 updateById 만들기 

package shop.mtcoding.blog.user;

import jakarta.persistence.EntityManager;
import jakarta.persistence.Query;
import lombok.RequiredArgsConstructor;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;
import shop.mtcoding.blog.board.Board;

@RequiredArgsConstructor
@Repository
public class UserRepository {

    private final EntityManager em;

    @Transactional
    public User updateById(int id, String password, String email) { // DTO를 안만들고 꺼내서 넘겨도 됨 -> 재사용 가능
        User user = findById(id);
        user.setPassword(password);
        user.setEmail(email);
        return user;
    } // 더티체킹

    public User findById(int id) { // 연관된 객체가 없음 -> 연관된 객체가 있으면 테스트 필요
        User user = em.find(User.class, id);
        return user;
    }

    @Transactional
    public User save(User user){
        em.persist(user);
        return user;
    }

    public User findByUsernameAndPassword(UserRequest.LoginDTO reqDTO){
        Query query =
                em.createQuery("select u from User u where u.username = :username and u.password =:password", User.class);
        query.setParameter("username", reqDTO.getUsername());
        query.setParameter("password", reqDTO.getPassword());
        return (User) query.getSingleResult();
    }
}

7. UserController 에서 update 만들기

  • URL에 ID가 없으므로 session에서 ID 가져오기
  • DTO에서 값을 받아 update 쿼리 실행하기
  • sessionUser 변수 만들어 mustach에 적용하기 
package shop.mtcoding.blog.user;

import jakarta.servlet.http.HttpServletRequest;
import jakarta.servlet.http.HttpSession;
import lombok.NoArgsConstructor;
import lombok.RequiredArgsConstructor;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;

@RequiredArgsConstructor
@Controller
public class UserController {

    private final UserRepository userRepository;
    private final HttpSession session;

    @PostMapping("/user/update")
    public String update(UserRequest.UpdateDTO reqDTO){
        User sessionUser = (User) session.getAttribute("sessionUser");
        User newSessionUser = userRepository.updateById(sessionUser.getId(), reqDTO.getPassword(), reqDTO.getEmail());
        session.setAttribute("sessionUser", newSessionUser);
        System.out.println(sessionUser);
        return "redirect:/";
    }

    @PostMapping("/join")
    public String join(UserRequest.JoinDTO reqDTO) {
        User sessionUser = userRepository.save(reqDTO.toEntity());
        session.setAttribute("sessionUser", sessionUser);
        return "redirect:/";
    }

    @PostMapping("/login")
    public String login(UserRequest.LoginDTO reqDTO) {
        User sessionUser = userRepository.findByUsernameAndPassword(reqDTO);
        session.setAttribute("sessionUser", sessionUser);
        return "redirect:/";
    }

    @GetMapping("/join-form")
    public String joinForm() {
        return "user/join-form";
    }

    @GetMapping("/login-form")
    public String loginForm() {
        return "user/login-form";
    }

    @GetMapping("/user/update-form") // session(mypage)에 있으니 id가 필요 없음
    public String updateForm(HttpServletRequest request) {
        User sessionUser = (User) session.getAttribute("sessionUser");
        User user = userRepository.findById(sessionUser.getId()); // 없어도 상관은 없음
        request.setAttribute("user", user);
        return "user/update-form";
    }

    @GetMapping("/logout")
    public String logout() {
        session.invalidate();
        return "redirect:/";
    }
}
