회원가입을 위한 DTO 만들기

SignUpRequest.java

@Data
@AllArgsConstructor
@NoArgsConstructor
public class SignUpRequest {
    private String username;
    private String password;
}

회원 정보를 저장하기 위한 Entity 생성

Account.java

@Data
@NoArgsConstructor
@AllArgsConstructor
@Entity
@Builder
public class Account {
    @Id @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;

    @Column(unique = true)
    private String username;

    private String password;

    private Role role;
}

Account를 저장하기 위한 Repository 생성

@Repository
public interface AccountRepository extends JpaRepository<Account, String> {
}

회원 가입 요청을 처리하기 위한 Service 생성

@Service
@RequiredArgsConstructor
public class AccountService {

    private final AccountRepository accountRepository;

    public Account saveAccount(SignUpRequest signUpRequest) {
        Account newAccount = Account.builder()
                .username(signUpRequest.getUsername())
                .password(signUpRequest.getPassword())
                .role(Role.USER)
                .build();

        return accountRepository.save(newAccount);
    }
}

Controller

회원가입에 필요한 Username과 Password를 갖고 /api/user/signup에 Post 요청을 보내면 회원가입이 정상적으로 이루어진 경우 Status Code : 200이 반환되게 된다.

JwtController.java

@RestController
@RequestMapping("/api/user")
@RequiredArgsConstructor
public class UserController {

    private final AccountService accountService;

    @PostMapping("/signup")
    public ResponseEntity signup(@RequestBody SignUpRequest signUpRequest){
        accountService.saveAccount(signUpRequest);
        return ResponseEntity.ok().build();
    }
}
