[v2] Spring 게시판 조금 알고 따라하기-3

회원가입 기능 구현

1. 컨트롤러 설정

@Controller
public class UserController {

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

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

2. 헤더에 링크 추가

3. 저장 기능 구현

  @Transactional
    public void save(String username, String password, String email) {
        Timestamp now = Timestamp.valueOf(LocalDateTime.now());

        User user = new User();
        user.setUsername(username);
        user.setPassword(password);
        user.setEmail(email);
        user.setCreatedAt(now);
        em.persist(user);

    }

// User(entity)
@CreationTimestamp
private Timestamp createdAt;

4. 테스트

@DataJpaTest // h2, em
@Import(UserRepository.class) // br
class UserRepositoryTest {

    @Autowired
    private UserRepository userRepository;

    @Test
    public void save_test() {
        String username = "haha";
        String password = "1234";
        String email = "haha@nate.com";

        userRepository.save(username, password, email);
    }
}

5. 컨트롤러 작성

  @Autowired
    UserRepository userRepository;

    @PostMapping("/join")
    public String join(@RequestParam("username") String username, @RequestParam("password") String password, @RequestParam("email") String email) {
        userRepository.save(username, password, email);
        return "user/join-form";
    }
