무엇을 했는가?

Order 엔티티

@Getter
@NoArgsConstructor
@Entity
@Table(name = "ORDERS")
public class Order {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private String id;
    @OneToMany(cascade = CascadeType.ALL)
    @JoinColumn(name = "ORDER_ID")
    private List<OrderItem> orderItems;
}

Payment 엔티티

@Getter
@NoArgsConstructor
@Entity
@Table(name = "PAYMENTS")
public class Payment {
    public enum State {
        PREPARE, PAYED, COMPLETE
    }

    @Id
    private String id;
    @Enumerated(value = EnumType.STRING)
    private State state;
    @OneToOne
    @JoinColumn(name = "ORDER_ID")
    private Order order;
}

Order Service

@Transactional
public PayRequest placeOrder(List<OrderItem> orderItems) {
    log.info("order service: {}", Thread.currentThread().getId());

    Order order = Order.builder()
        .id(UUID.randomUUID().toString())
        .orderItems(orderItems)
        .build();

    orderRepository.save(order);

    PayReady payReady = kakaoPay.prepare(order);

    return PayRequest.builder()
        .payReady(payReady)
        .order(order)
        .build();
}

Payment Service

@Transactional(propagation = Propagation.MANDATORY)
public PayReady prepare(Order order) {
    log.info("pay: {}", Thread.currentThread().getId());

    Payment payment = Payment.builder()
        .id(UUID.randomUUID().toString())
        .order(order)
        .build();

    paymentRepository.save(payment);

    return prepareKakaoPay(payment);
}

어떤일이 있었는가?

발생한 예외 메시지

어떻게 하였는가?

Order 엔티티를 영속화 하고 Payment를 영속화 했는데, Payment를 영속화 하는 과정에서 Order 엔티티를 찾을 수 없다고 예외가 발생했다.

트랜잭션 전파 문제인가 싶어 여러 설정을 해보았는데도 마찬가지였고, cascade 옵션을 줘봤는데 update 쿼리가 나가면서 Order 엔티티가 2개가 생겼다.

아.. Id를 지정해줬는데 @GeneratedValue를 사용해버렸다.

@GeneratedValue를 제거해준다.

IDENTITY : 데이터베이스에 위임(MYSQL)
- Auto_Increment
SEQUENCE : 데이터베이스 시퀀스 오브젝트 사용(ORACLE)
- @SequenceGenerator 필요
TABLE : 키 생성용 테이블 사용, 모든 DB에서 사용
- @TableGenerator 필요
AUTO : 방언에 따라 자동 지정, 기본값
