Assertions.assertEquals(result,member); 하고 assertThat(member).isEqualTo(result); 에서.. 위 메소드는 실행시간이 23ms이고 아래 메소드는 실행시간이 70ms로 나오는거 같은데.. 아래 문법이 더 좋은점이 있나요?..
안녕하세요 질문 사항이 있어 글을 남깁니다. 구글링을 통해 Member findMember = memberService . findOne ( savId ). get (); 부분이 오류가 있다는 것을 알았습니다. 그리고 나서 다시 로직을 보면서 다시 하여도 똑같은 오류가 발생해 글을 올립니다.

@Around에서 리턴값을 바꾸면 ClassCastException이 발생합니다. Controller에 aop를 적용해서 target controller는 String을 반환하게 했고 advice에서는 ResponseEntity를 반환하게 설정했는데요... 다음과 같은 오류가 발생합니다.. 디버깅을 찍어봐도 이유를 모르겠습니다. 원인이 무엇인지 알려주시면 감사하겠습니다!!!

책 381쪽에 보면 페치 조인 대상에는 별칭을 줄 수 없다라고 나오고, 대신 하이버네이트같은 몇몇 구현체는 지원해 준다고 나와있더라구요 "select distinct o from Order o" + " join fetch o.member m" + " join fetch o.delivery d" + " join fetch o.orderItems oi" + " join fetch oi.item i", 위와 같은 JPQL에서 o.orderItems 과 페치조인하고 oi로 별칭을 주었는데, 이 별칭을 활용하여 join fetch oi.item i 처럼 또 페치조인을 하는데... JPA에서 공식 스펙은 아니지만 하이버네이트가 잘 지원해주는 것 맞나요? 최종 질문은 저렇게 페치조인 대상에 별칭주고 거기서 또 페치조인해서... 잘 써도 되는지 궁금합니다. JPA의 공식스펙이 아닌것 같은데 문제없이 동작하는지.. (위 같은 경우는 당연 일대일이나 다대일에서만 쓸것입니다)
윈도우는 h2.bat으로 접속을 했습니다. 2:08 부분에서 ll 와 ls - arlth 명령어를 통해 jpashop.mv.db가 생성되는 것을 확인할 때 윈도우 명령어로는 어떻게 진행해야 할까요? 보시는 것처럼 연결하게 되면 키 입력이 먹히지 않아 확인을 어떻게 해야할지... 윈도우 명령어랑 리눅스 명령어 비교를 해보려고 찾아봤는데 딱 맞는게 없는거 같아서 질문드립니다.
