안녕하세요 선생님. 좋은 강의 너무 감사드립니다 ^^! 질문 드릴 게 있는데, 채점 사이트에서 답안을 제출할 때, solution 메소드를 System.out.print로 꼭 감싸서 "출력"을 해줘야 하는건가요? 기업 코딩테스트에서 answer로 return 되는 값이 정답의 기준이 되는 것 같았는데 헷갈려서요..! 아니면 문제에 출력 "선생님이 볼 수 있는 최대학생수를 출력한다."라고 명시되어 있는 경우 기업 코딩테스트에서도 System.out으로 출력해줘야 하는 건가용?? 좀 바보 같은 질문인데 도움 부탁드립니다! 감사합니다.

stream이 아닌 querydsl transform을 이용하는 방법에대한 문의

미해결

실전! 스프링 부트와 JPA 활용2 - API 개발과 성능 최적화

안녕하세요 8:30초대 강의를 보면 1:N관계의 list형태를 mapping하기 위해 flats .stream ~ .collect ~ 형태를 이용하고 있는데요 실무에서도 비슷한 사례가있어, 처음에 강사님처럼 어플리케이션단에 코드를 짰다가, 코드가 너무 복잡해져서 QueryDsl에서 transform + GroupBy.list를 이용하는식으로 변경해봤는데요. (아래 예시참조) from(Entity) // 1:N 관계의 List<Object> 를 추출, key : Entity.Id .transform( groupBy(Entity.Id) .list( Projections.fields(Example.class, Entity.Id, list( Projections.fields(Detail.class, Detail.id Detail.name ) ).as("DetailList") ) ) ) 문제는 구글링을 해보니, 해당 방식이 쿼리결과를 memory에서 리스트형태로 만들어내는것이라고 하더라구요. 예전에 강사님의 강의에서 '컬렉션 fetch join은 페이징을 이용할 수 없다'는 내용을 설명해주실 때, 해당 동작이 메모리에서 일어나기때문에 OOM이 발생할 수 있다 라고 말씀해주셨는데 이와 마찬가지로 transform , Groupby.list를 이용하는 것 역시 문제가 발생할까봐 우려스럽네요 아래 두가지 질문에 답변 부탁드립니다. Q1) 강사님의 application단에서 짜는 방식이 나을지 아니면 querydsl단에서 transform & Groupby.list를 이용하는게 나을지 고민되는데 두가지 방법중 무엇을 선택하는게 좋을까요? 후자의 경우 OOM이 발생하지는 않을지도 궁금합니다.. Q2) memory에서 작업하는게 위험한 이유가 뭔가요? 강사님처럼 application단에서 로직을 수행하는것도 memory에서 동작하는것 아닌가요? 친절하고 유익한 강의 늘 감사드립니다. 답변 부탁드립니다!

선생님 저 코드에서 최단거리인지 판별하는 것은 dis[7][7]에 어떤 수가 들어가면 바로 코드가 종료되는 조건도 없는데 어떻게 판별하는 것인가요...? 이 문제는 도착지점까지 도착하는 경로가 2개 뿐이라서 while(!Q.isEmpty()) 이 조건때문에 둘 중에 먼저 도착하면 자동으로 다른 경로를 계산할 때, Queue가 비어있게 되어서 반복문이 종료되어서 그게 가능하지만 도착하는 경로가 3개 이상일 경우에는 불가능 할 것 같은데 그때는 따로 조건을 추가해줘야 되나요...?

안녕하세요. ec2 로 인스턴스를 생성 후 git 에 있는 springboot 기반의 프로젝트를 clone 후 .jar 로 배포를 시키려던 참이였습니다. ec2에는 openjdk11, mysql-server, git 설치 후 clone을 진행하고, 프로젝트 내부에 gradlew 파일에 chmod로 777 권한을 주고 build 를 진행시켰습니다. 보통 전에 하던 프로젝트는 빌드시간이 1분채 걸리지 않았는데, build 중에 complieJava 에서 지금 45분째 넘어가지 않고, 서버가 멈춘듯 합니다. 어떤 문제를 살펴봐야 할까요?

select t from Team t join fetch t.members m 을 할시에List<Members> 컬렉션에는 프록시들로 채워지는게 아닌가요? 디버깅을 해보고 싶지만 디버깅 하는 순간 해당 variable을 조회하기에 바로 db에서 진짜를 가져오는 것 같습니다. (Lazy임에도 불구하고) 제가 이해한바로는 위의 쿼리 실행 직후에는 List<Members>에 프록시 객체들로 채워질 것 같은데 맞나요? 아니라면 뭘 공부해보면 좋을까요..?

안녕하세요! 강의 너무 잘 듣고 있습니다! 강의를 듣다가 DTO 조회 방식에 대해 헷갈리는 부분이 있어 질문드립니다. DTO 조회 방식은 엔티티가 아니기 때문에 지연로딩이나 페치 조인을 사용할 수 없다고 알고있습니다. 그럼 DTO 조회 방식은 단순히 DB에서 데이터를 가져와서 DTO의 필드에 값을 채워주는 방식이고, 이 때, 엔티티에는 값을 따로 할당하지 않는건가요?? 그렇다면 영속성 컨텍스트에도 DB에서 조회한 데이터가 들어가지 않나요?

LazyLoading 시 가져오는 객체에 대해 질문이있습니다!

미해결

실전! 스프링 데이터 JPA

[질문 내용] 안녕하세요 영한님 JPA 를 공부하다가 LazyLoading 관련해서 의문점이 생겨 질문남깁니다. 연관관계에서의 LazyLoading 은 실제 entity를 가져오는것이 아닌 프록시객체의 target이 entity와 연결되어있는것으로 알고있습니다. 그래서 Team(1) <-> Member(n) 의 관계라고 가정했을때 Member 에서의 @ManyToOne 관계에서의 LazyLoading 으로 객체를 가져오게 되면 Team은 `Team$HibernateProxy$95RMKfgq@13875` 이런 형식으로 프록시 객체를 갖고있는것을 확인했습니다. 다만 Team에서 @OneToMany 관계의 Member를 LazyLoading 호출하게되면 List<Member> 의 형식이 PersistentBag 의 객체형식을 가지고있는것까지는 이해했는데 컬렉션 내의 객체는 제가 생각했던 `Member$HibernateProxy$95RMKfgq@13875` 와 같은 프록시 객체의 형태가 아닌 `Member@13867` 과 같은 실제 객체를 가지고 있는것으로 확인했습니다. 이와 관련해서 PersistenceCollection 이나 StatefulPersistenceContext 클래스의 관련된 문서를 찾아봤지만 답을 찾지못해 여쭤봅니다ㅠㅜ 추가로 entityManagerFactory getPersistenceUnitUtil().isLoaded 메소드를 이용해서 List 객체를 조회했을땐 false 로 확인했습니다. 다만 디버그모드로 봤을때는 ManyToOne 과 다르게 실제객체형태로 보이네요ㅠㅜ 디버그모드로 확인시 값을조회해야해서 의도치않게 추가쿼리가 발생되는것은 인지하고있지만 이 케이스는 이해가 되질 않네요 ㅎㅎ
