[질문 내용]스프링 로드맵에서는 core의 Assertions를 사용했는데 여기에서는 jupiter의 Assertions를 사용해서 궁금한 점이 생겼습니다. 둘은 어떤 차이이며, 현재는 어떤것을 더 선호하는지 궁금합니다.현재 저는 스프링 로드맵에서 했던것 처럼 core의 Assertions를 사용해 하고 있는데 정상테스트와 오류테스트를 모두 core로 할 수 있다면 core로 하는게 더 좋을까요?

안녕하세요 호돌맨님 이번 강의 내용중 3번 enum을 이용한 방식에 대한 궁금증이 생겨서 질문 드립니다.제가 생각했을때 enum방식은 제한적이라 실무에서는 자주 쓰이지 않을 것 같다는 의문이 생겼습니다.제한적이라고 생각했던 부분은reflection을 이용한 인스턴스 생성이므로 스프링이 제공해주는 AOP프록시나 DI의 혜택을 받을 수 없다.입니다.예시로 들어주신 AnimalSerivce의 구현 클래스들은 트랜잭션이나 기타 AOP기능을 하용하지 않고, 주입받아야 하는 의존성도 없어서 괜찮지만 만약 Controller -> Service를 호출하는 동일한 구조로 호출 대상이 되는 Service가 AOP프록시나 DI등의 처리가 필요한 클래스라면 AOP미적용, 또는 newInstance() 호출 시 예외 발생등의 문제가 발생할 것으로 보입니다.실제로 실무에서 변수값에 따라 서로 다른 클래스 컴포넌트를 호출해야하는 상황에서 enum방식이 자주 쓰이나요??

이제 막 java, spring, mysql , 프론트 부분 기초적인 부분 공부를 끝마친 학생입니다.항상 테스트 코드의 중요성을 많은 커뮤니티에서 봐오고 강조하는 분들이 많아서언젠간 배워야겠다 싶은 찰나에 수강 결제를 미리 하게 되었습니다.혹시 선생님 수업을 듣기 전, 미리 좀 더 배워둬야 하거나알아둬야 하는 부분이 있을까요 ?

(예/아니오)[질문 내용]안녕하세요.카운트 쿼리 분리 부분을 듣는 도중에 카운트 쿼리에 LEFT JOIN이 사용되는 결과를 확인하기 위해 다음처럼 코드를 작성하였습니다.public interface MemberRepository extends JpaRepository<Member, Long> { @Query(value = "select m from Member m left join m.team t") Page<Member> findByAge(int age, Pageable pageable); ... } @Test public void paging() throws Exception { //given memberRepository.save(new Member("member1", 10)); memberRepository.save(new Member("member2", 10)); memberRepository.save(new Member("member3", 10)); memberRepository.save(new Member("member4", 10)); memberRepository.save(new Member("member5", 10)); //when PageRequest pageRequest = PageRequest.of(0, 3, Sort.by(Sort.Direction.ASC, "username")); Page<Member> page = memberRepository.findByAge(10, pageRequest); //then List<Member> content = page.getContent(); assertThat(content.size()).isEqualTo(3); assertThat(page.getTotalElements()).isEqualTo(5); assertThat(page.getNumber()).isEqualTo(0); assertThat(page.getTotalPages()).isEqualTo(2); assertThat(page.isFirst()).isTrue(); assertThat(page.hasNext()).isTrue(); }그런데 결과는 강의와는 달리 카운트 쿼리에 LEFT JOIN 이 사용되지 않았고, 심지어 JPQL select m from Member m left join m.team t 을 @Query에 작성했음에도 조회 쿼리도 LEFT JOIN을 사용하지 않은 것을 확인했습니다.이후 스프링 부트 3 이하 버전에서 동일한 코드로 실행해보니 강의와 동일한 결과를 얻을 수 있었습니다.스프링 부트 3 부터 적용된 스프링 데이터 JPA 에서는 이러한 부분의 최적화를 자동으로 제공하는 것일까요?

안녕하세요 선생님. 빌더를 사용하시는 것을 보고 흥미가 동해 질문남깁니다!선생님께서는 예제의 경우 대부분 생성자를 private으로 막아두고 빌더를 통해서만 객체를 생성하시는 것 같습니다.저는 필드 개수가 많아도 public 생성자로 열어두는 편인데, 그 이유는어떤 인자를 전달해야할지 인텔리제이의 힌트로 알아채기도 편하고필드가 null 일 수도 있는 경우 객체를 생성할 때 명시적으로 null 이 보이는게 낫다 라고 생각해서입니다. null을 명시적으로 인자로 전달하는 것이 불편하다면 텔레스코핑을 통해 생성자를 조금 더 만들어두기도 합니다 :)물론 빌더 패턴을 사용하면 이런 코드들이 전부(?) 사라지기는 하지만, 이 외에 빌더로 객체 생성을 강제하는 것에 대한 장점이 있는지 궁금합니다! 또, 선생님만의 빌더랑 생성자 선택 기준이 따로 있을까요? 마지막으로 실무에서도 자주 사용하시는지 궁금합니다. 좋은 강의 감사드립니다 :)

원문입니다.DISTINCTStarting with Hibernate ORM 6 it is no longer necessary to use distinct in JPQL and HQL to filter out the same parent entity references when join fetching a child collection. The returning duplicates of entities are now always filtered by Hibernate.Which means that for instance it is no longer necessary to set QueryHints#HINT_PASS_DISTINCT_THROUGH to false in order to skip the entity duplicates without producing a distinct in the SQL query.From Hibernate ORM 6, distinct is always passed to the SQL query and the flag QueryHints#HINT_PASS_DISTINCT_THROUGHhas been removed.

자바 ORM 표준 JPA프로그램 듣고 넘어왔습니다.이전 기본강의에서는 JPQL이 flush를 먼저 수행이 된후 JPQL쿼리가 동작한다고 배웠는데요.이게 EntityManager의 일반적인 find() 메소드의 경우clear()을 한 뒤 준영속상태에서 비로서 select쿼리가 나가는것으로 알고있습니다. (그렇지 않으면 1차 캐시에서 조회)근데 JPQL의 경우 flush는 자동으로 호출 되지만 clear 즉, 1차캐시와 연관성이 있느냐 없느냐에 대해서 궁금증이 생겼습니다.clear를 직접 해주지 않았음에도 불구하고 쿼리가 나가는 이유에 대해서 clear를 자동으로 해줘서 쿼리가 나가게 된것인지? 혹은 1차 캐시와 상관없이 자연쿼리가 나가게 되는것인지 한번 더 다잡고 가고싶습니다.답변 감사히 기다리겠습니다.
