✅ 구조

✅ 코드 작성하기

user-service에서 아래 코드 작성하기

1. PointClient 코드 작성하기
포인트 서비스에 API 요청을 보내는 코드를 작성하자.
application.yml

server:
  port: 8080

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/user-db
    username: root
    password: password
    driver-class-name: com.mysql.cj.jdbc.Driver
  jpa:
    hibernate:
      ddl-auto: update
    show-sql: true

client:
  point-service:
    url: http://localhost:8082

 
dto/AddPointsRequestDto

public class AddPointsRequestDto {
  private Long userId;
  private int amount;

  public AddPointsRequestDto(Long userId, int amount) {
    this.userId = userId;
    this.amount = amount;
  }

  public Long getUserId() {
    return userId;
  }

  public int getAmount() {
    return amount;
  }
}

 
client/PointClient

@Component
public class PointClient {

  private final RestClient restClient;

  public PointClient(
      @Value("${client.point-service.url}") String pointServiceUrl
  ) {
    this.restClient = RestClient.builder()
        .baseUrl(pointServiceUrl)
        .build();
  }

  public void addPoints(Long userId, int amount) {
    AddPointsRequestDto addPointsRequestDto 
        = new AddPointsRequestDto(userId, amount);
    this.restClient.post()
        .uri("/points/add")
        .contentType(MediaType.APPLICATION_JSON)
        .body(addPointsRequestDto)
        .retrieve()
        .toBodilessEntity();
  }
}

 

2. Service 코드 작성하기
회원 가입 로직에 포인트 적립 로직을 추가해야 한다.
service/UserService

@Service
public class UserService {
  private final UserRepository boardRepository;
  private final PointClient pointClient;
  
  public UserService(UserRepository userRepository, PointClient pointClient) {
    this.userRepository = userRepository;
    this.pointClient = pointClient;
  }

  public void signUp(SignUpRequestDto signUpRequestDto) {
    User user = new User(
        signUpRequestDto.getEmail(),
        signUpRequestDto.getName(),
        signUpRequestDto.getPassword()
    );
    
    User savedUser = this.userRepository.save(user);
    
    // 회원가입하면 포인트 1000점 적립
    pointClient.addPoints(savedUser.getUserId(), 1000);
  }
  
  ...
  
}

 

3. 서버 다시 실행시키기
 

4. 서버 실행시켜서 API 테스트해보기
