em.persist(book); 이게 빠졌었네요 해결했습니다 감사합니다 강사님!

안녕하세요. 민동댕동님 오류 메시지를 보면 다음 두줄에서 힌트를 얻을 수 있습니다. Caused by: java.lang.IllegalArgumentException: id to load is required for loading -> 데이터를 로드 하려면 id가 필요합니다. at jpabook.jpashop.repository.ItemRepository.findOne(ItemRepository.java:25) -> itemRepository.findOne의 25번 줄을 호출하면서 예외가 발생했습니다. 그렇다면 여기서 book.getId()에 데이터가 있는지 없는지 보면 되겠지요^^? Long orderId = orderService.order(member.getId(), book.getId(), orderCount);
