OrderServiceTest 테스트 중 오류

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("회원1");
        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<Order> 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<Order> findAll(OrderSearch orderSearch) {}
}

h2 DB는 켜져있고, test용 application.yml도 아래처럼 해당 옵션만 적어놓은 상태인데 어느 부분이 잘못되어 있는 걸까요?

OrderServiceTest에서 상품주문_재고수량초과 테스트는 정상 동작합니다. 이 테스트에서도 orderService.order()를 호출하는데 잘 동작하는 거면 다른 부분에 문제가 있는 걸까요?

안녕하세요. 민준님

오류 메시지를 보니 Order 엔티티에 @Id 매핑이 Long 타입인지 확인해주세요.

감사합니다.
