✅ 회원가입 API 만들기

1. User 엔티티 생성하기
User

@Entity
@Table(name = "users")
public class User {

  @Id
  @GeneratedValue(strategy = GenerationType.IDENTITY)
  private Long id;

  private String email;

  private String name;

  private String password;

  public User() {
  }

  public User(String email, String name, String password) {
    this.email = email;
    this.name = name;
    this.password = password;
  }

  public Long getId() {
    return id;
  }

  public String getEmail() {
    return email;
  }

  public String getName() {
    return name;
  }

  public String getPassword() {
    return password;
  }
}

2. UserRepository 만들기
UserRepository

public interface UserRepository extends JpaRepository<User, Long> {
}

 

3. Controller 만들기
UserController

@RestController
@RequestMapping("/api/users")
public class UserController {
  private final UserService userService;

  public UserController(UserService userService) {
    this.userService = userService;
  }
  
  @PostMapping
  public ResponseEntity<String> signUp(
      @RequestBody SignUpRequestDto signUpRequestDto
  ) {
    userService.signUp(signUpRequestDto);
    return ResponseEntity.ok("회원가입 성공");
  }
}

 

4. RequestDto 만들기
SignUpRequestDto

public class SignUpRequestDto {
  private String email;
  private String name;
  private String password;

  public String getEmail() {
    return email;
  }

  public String getName() {
    return name;
  }

  public String getPassword() {
    return password;
  }
}

 

5. Service 만들기
UserService

@Service
public class UserService {
  private final UserRepository userRepository;
  private final KafkaTemplate<String, String> kafkaTemplate;

  public UserService(UserRepository userRepository, KafkaTemplate<String, String> kafkaTemplate) {
    this.userRepository = userRepository;
    this.kafkaTemplate = kafkaTemplate;
  }

  public void signUp(SignUpRequestDto signUpRequestDto) {
    
  }
}
