OrderServiceTest 테스트 중 오류

Question

OrderServiceTest의 상품주문 부분을 따라하던 중에 계속 오류가 나서 질문 올립니다. 우선 제가 작성한 상품주문 코드는 아래와 같습니다. @Test public void 상품주문 () throws Exception { Member member = new Member (); member . setName ( " 회원 1" ); member . setAddress ( new Address ( " 서울 " , " 강가 " , "123-123" )); em . persist ( member ); Item item = new Book (); item . setName ( " 시골 JPA" ); item . setPrice ( 10000 ); item . setStockQuantity ( 10 ); em . persist ( item ); int orderCount = 2 ; Long orderId = orderService . order ( member . getId (), item . getId (), orderCount ); Order getOrder = orderRepository . findOne ( orderId ); assertEquals ( " 상품 주문시 상태는 ORDER" , OrderStatus . ORDER , getOrder . getStatus ()); assertEquals ( " 주문한 상품 종류 수가 정확해야 한다 ." , 1 , getOrder . getOrderItems (). size ()); assertEquals ( " 주문 가격은 가격 * 수량이다 ." , 10000 * 2 , getOrder . getTotalPrice ()); assertEquals ( " 주문 수량만큼 재고가 줄어야 한다 ." , 8 , item . getStockQuantity ()); } 테스트를 돌려보면 orderService.order() 이 부분에서 오류가 발생하고 오류를 타고 들어가보면 orderRepository.save()에서 오류가 납니다. 아래는 OrderService와 OrderRepository 코드 입니다. @Service @Transactional ( readOnly = true ) @RequiredArgsConstructor public class OrderService { private final MemberRepository memberRepository ; private final OrderRepository orderRepository ; private final ItemRepository itemRepository ; @Transactional public Long order ( Long memberId , Long itemId , int count ) { Member member = memberRepository . findOne ( memberId ); Item item = itemRepository . findOne ( itemId ); Delivery delivery = new Delivery (); delivery . setAddress ( member . getAddress ()); delivery . setStatus ( DeliveryStatus . READY ); OrderItem orderItem = OrderItem . createOrderItem ( item , item . getPrice (), count ); Order order = Order . createOrder ( member , delivery , orderItem ); orderRepository . save ( order ); // because of cascade option return order . getId (); } @Transactional public void cancelOrder ( Long orderId ) { Order order = orderRepository . findOne ( orderId ); order . cancel (); } // public List findOrders(OrderSearch orderSearch) {} } @Repository @RequiredArgsConstructor public class OrderRepository { private final EntityManager em ; public void save ( Order order ) { em . persist ( order ); } public Order findOne ( Long id ) { return em . find ( Order . class , id ); } // public List findAll(OrderSearch orderSearch) {} } h2 DB는 켜져있고, test용 application.yml도 아래처럼 해당 옵션만 적어놓은 상태인데 어느 부분이 잘못되어 있는 걸까요? logging.level : org.hibernate.SQL : debug 아래는 오류 내용입니다. org.springframework.orm.jpa.JpaSystemException: Unknown integral data type for ids : java.lang.String; nested exception is

다른 부분에 문제가 있는 걸까요?

안녕하세요. 민준님 오류 메시지를 보니 Order 엔티티에 @Id 매핑이 Long 타입인지 확인해주세요. 감사합니다. Unknown integral data type for ids : java.lang.String; nested exception is org.hibernate.id.IdentifierGenerationException: Unknown integral data type for ids : java.lang.String
