커멘드와 쿼리 분리에 대해
안녕하세요 항상 강의 잘 듣고 있습니다! 제가 이해력이 부족하여 모든 질문을 보았음에도 이해가 가지않아 질문 합니다! ㅜ 현재 강의의 예시에는 -------- orderV3 컨트롤러 -> 읽기전용 @Transactional이 설정된 OrderQueryService -> OrderRepository 이렇게 호출이 되어 있는데요 -------- 이 예시는 핵심 비즈니스 로직 없이 OrderQueryService 즉 화면이나 API에 맞춘 서비스만 있는 예시인건가요 ? 아니면 Repository 호출을 OrderService가 있다고 치고 OrderQueryService안에 OrderService(핵심비즈니스로직)이 있고 그안에 OrderRepository를 호출 했다고 치는건가요 ? -------- (예를들면 이렇게 ) orderV3 컨트롤러 -> OrderQueryService -> OrderService(생략) -> OrderRepository -------- 결론은 OrderService와 OrderQueryService가 같이 어떻게 쓰여지는지 이해가 가질 않습니다..

gradle build 중 complieJava 멈춤현상
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?

미해결자바 ORM 표준 JPA 프로그래밍 - 기본편
27:10 분쯤에 "정확하게 컬렉션은 프록시는 아닌데.." 관한 질문입니다.
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..?

DTO 조회 방식 질문있습니다!
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!
[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

해결됨자바(Java) 알고리즘 문제풀이 입문: 코딩테스트 대비
풀이과정 질문합니다.
안녕하세요!! 이번 문제는 강의를 보기전에 혼자서 풀어봤습니다. 저는 이문제를 2중for문으로 해결했습니다. 그리고 강의를 시청했는데 풀이 방법이 다르더군요... 그래서 갑자기 궁금해졌는데 코딩테스트문제를 풀때 언어에 내장되있는 기능들을 사용해도 되는건가요?? 아니면 하나하나 직접 만들면서 풀어야하는건가요?? 갑자기 궁금하네요.. ㅎㅎ

연관관계와 관계가 없다?
영속성 전이가 연관 관계 세팅과 전혀 관계가 없다는 설명이 잘 이해가 되지 않습니다. 연관 관계가 맺어져 있어야 영속성 전이도 이루어질텐데 어떤 의미에서 이렇게 설명하신건지 궁금합니다. 감사합니다.

여러곳에서 한 테이블의 list가 필요한 경우엔?
만약 다음과 같이 여러곳에서 image라는 테이블을 참조한다면.. 그땐 어떻게 코드를 구현해야하는건가요?프로젝트와 이미지는 1:n관계지만 이를 일대다로도 다대일로도 구현할 수있잖아요?1. 만약에 다대일 양방향으로 구현 2. 일대다 단방향으로 구현 >>첫번째질문 : 어느것으로 해도 상관없나요? 근데 2번 방법을 지양하라고 하셨던 것 같아요 그래서 만약 1번 방법으로 한다고 가정할게요. 이미지 테이블같은경우 어떨땐 프로젝트의 이미지가 될수있고 (그러면 게시글의 이미지는 아닐테니 게시글_id값은 null이 되겠죠) 어떨땐 게시글의 이미지가 되겠죠..? >>두번째질문 : 근데 이 이미지가 게시글의 이미지인지 프로젝트의 이미지인지가 중요할까요..? >>세번째질문 : 만약에 중요하다면 enum을 사용하여 어떤 것의 이미지인지를 반환하는 메서드를 만들어주면되는건가요/?

미해결스프링 시큐리티
SecurityContextHolder 관련 질문이 있습니다!
안녕하세요. 항상 좋은 강의 감사드립니다! SecurityContextholder 관련 질문이 있어 글을 적게 되었습니다. SecurityContext는 ThreadLocal 기반이고, 이를 전역에서 사용할 수 있도록 Static 변수인 SecurityContextHolder에 저장된다고 이해를 했습니다. (강의 내용을 참고, 혹시.. SecurityContextHolder가 Static 변수가 아니라면 정정해주시면 감사하겠습니다!) 여기서 궁금한 부분은... 멀티 쓰레딩 환경입니다. 스프링 MVC는 결국 요청마다 쓰레드가 할당되는 쓰레딩풀 환경이라 멀티 쓰레드로 동작을 하고 있는 것으로 알고 있습니다. 그렇다면 동시에 사용자로부터 인증 요청이 온다면, 동시에 SecurityContextHolder에 SecurityContext가 각각 저장된다는 것인데.. 이런 환경에서 어떻게 동작하는지 잘 이해하기가 어렵습니다. 예를 들어 동시에 인증 요청이 오게 되면, SecurityContextHolder의 동시성 문제는 어떻게 처리되는 걸까요? 항상 좋은 강의 감사드립니다 좋은 하루 되세요!

컨트롤러 view 호출
안녕하세요 강의 듣고 혼자 이것저것 해보고있는데 타임리프 의존성을 추가하지 않으면 컨트롤러에서 view를 호출을 못하던데 스프링 부트로 컨트롤러로 view를 호출하려면 무조건 타임리프 의존성을 추가해야하는지 궁금해서 질문드립니다.

CQS 관련 질문
안녕하세요 선생님 강의 정말 재밌게 듣고 있습니다 다름이 아니라 Service에 join메서드에서 id(Long) 값을 반환해주고 있는데 선생님께서 앞서 질문에서 CQS라고 말씀해주셨습니다. 서비스에서는 테스트의 용이성 등등 여러 장점때문에 Id값을 반환하는게 좋다고 말씀해주셨는데 컨트롤러에서는 join 이나 혹은 다른 Command쿼리를 날리는 메서드들에서 반환값은 어떤게 좋을까요.. id를 반환해 줄 수도 있는거고 void를 반환할 수 도 있는데 어떤게 best practice 인지 궁금합니다.
