 자료받고 푸니까실행시킬때마다 오류코드가 다르게 나옵니다.MYSQL 8.0을 원래 있던 거 사용하고 있었는데 MYSQL 문제일수도 있나요??오류코드가 똑같으면 알겠는데 이건 뭐 실행시킬때마다 다르게 나와서 당황스럽네여...

<property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect"/> 에서 Mysql방언 변경 <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect"/MySQL5Dialect로 바꾸니까 안됩니다.

@Test void theta_join() { em.persist(new Member("teamA")); em.persist(new Member("teamB")); em.persist(new Member("teamC")); List<Member> result = queryFactory .select(member) .from(member) .join(member.team, team) .where(member.username.eq(team.name)) .fetch(); System.out.println("result = " + result); // => result = [] assertThat(result).extracting("username").containsExactly("teamA","teamB"); }위와 같은 쿼리문의 결과는 빈 결과값이 나오는데 이유를 모르겠습니다. 바로 밑의 질문이랑 비슷한데 답변이 잘 이해가 되지 않아 질문을 올렸습니다.

강사님은 member 테이블 필드값에 order 리스트를 없애서 단방향 연관관계를 보통 한다고 하시는데(6:22초) 어떤 상황에서 그렇게 되나요 ??? ADMIN쪽 개발 관련된 부분인가요 ?? 예를 들면 배송사이트에서 나의 주문정보 보기 와 같은 페이지는 오히려 member 테이블 필드값에 order 리스트가 필요하지 않나요 ??

안녕하세요 수업을 듣다 궁금한 게 생겨 질문합니다!!detach와 remove 메서드를 비교하면서 헷갈리는 부분이 생겨났습니다!!원래는 persist가 호출된 시점에 SQL 쓰기지연 저장소에 insert 쿼리가 저장되는 것으로 이해했지만 detach()가 호출됐을 때 insert문이 나가지 않는 것을 보고 저는 persist가 호출됐을 때 SQL 쓰기지연 저장소에 insert 쿼리가 저장되는 것이 아니라 flush를 호출할 때 1차 캐시에서의 변경사항(스냅샷 비교 또는 새로운 엔티티 등록)으로 인해 insert 쿼리가 나가는 것이 아닌가로 생각했습니다.하지만 remove를 호출했을 때 insert문이 나가고 delete문이 따로 나가는 것을 보고 헷갈리기 시작했습니다. 만약 변경 감지 기능이라는 것이 기존의 1차 캐시에 저장된 엔티티와 스냅샷을 비교하여 다른 부분을 update 쿼리를 자동으로 실행해주는 기능이라 생각한다면 위의 remove 실행 시 DB로 보내진 쿼리가 이해가 됩니다. 새로 등록한 것과 삭제하는 것은 스냅샷으로 비교할 수 없기 때문에 persist나 remove 호출 시점에 따로 SQL 쓰기지연 저장소에 쿼리를 저장할 수 밖에 없다라고 생각하기 때문입니다. 하지만 이렇게 생각했을 경우 위의 detach 실행 시 쿼리가 이해가 안됩니다.. 제가 어디서 헷갈리고 있는 걸까요??

안녕하세요 영한님 강의 잘 듣고 있습니다^^전부터 궁금해 왔던 것인데요, 팩토리를 만들 때 정적으로 올리는 이유에 대해서 궁금합니다영한님이 다른 QnA에서 추천해 주신 내용들을 읽어보았으나 굳이 왜 "정적"영역으로 보내는 가에 대한 의문은 쉽게 풀리지 않습니다 ㅜㅜ일단 정적 팩토리 메서드로 보내면 생성자들에 대한 응집도가 크게 떨어지는 느낌입니다. "엘레강트 오브젝트"라는 책을 보면 생성자는 10~15개 까지도 만들고 퍼블릭 메서드를 최대한 적게 가져가라고 가이드를 주는데요, 정적 영역으로 보내면 주/부 생성자로 보낼 수 없기 때문에 그 많은 생성자들이 다 흩어지고, 생성자들 간 관계를 맺을 수 없기 때문에 유연성이 떨어지고 코드 중복이 자주 일어나는 효과가 나는 것 같습니다이는 굳이 정적 영역으로 보내지 않고 주/부 생성자로 구분하면 쉽게 해결될 일이 아닌가? 하는 생각도 들어 질문을 드립니다

bootstrap.yml파일에는 암호화할 때 사용하는 개인키 위치만 알려줬는데 어떻게 복호화를 할 수 있는 건가요?디렉토리에 공개키를 생성했다고는 하지만 yml파일에 위치를 설정하진 않았는데 어떻게 복호화를 할 수 있는지 궁금합니다.
