이전에 혼자 ddd, 헥사고날 아키텍처를 공부하면서 느꼈던게 객체지향적인 코드 + 테스트하기 용이한 코드를 작성하기 위해서는 결국 domain layer와 persistence layer의 분리가 필수적인데 jpa entity와 domain entity를 완전히 분리했을 때 JPA가 mybatis나 jdbc template를 사용하는 것과 비교해 가지는 강점이 있는지 잘 모르겠습니다.. 그나마 jpa entity와 domain entity를 분리하지 않는다면 어떻게든 온몸 비틀기로 그나마 테스트하기 용이하고 객체지향스러운 코드를 작성해볼 수는 있지만 결국 복잡한 로직에서는 쿼리 때문에 문제가 생기고 ㅜ 지식 공유자님께서는 이 문제에 대해 어떻게 생각하시나요?
Collection.Map의 Good 케이스를 알 수 있을까요? 맵을 사용할 때 맵 안에 맵이 있고 이런 형태를 사용하지 않는게 좋은건지 아니면 따로 dto로 변환해서 사용해야하는건지 구분이 안 가서 질문 드립니다 ! 지정된 scope를 넘나들지 않는다는 것도 이해가 가지 않습니다 ㅠㅠ 조금만 더 쉽게 설명 붙여주시면 감사드리겠습니다!
강의에서는 아래와 같이 select 쿼리를 이용해 업데이트 된 회원을 조회후 response로 전달해 주었는데 @PutMapping("/api/v2/members/{id}") public UpdateMemberResponse updateMemberV2(@PathVariable("id") Long id, @RequestBody @Valid UpdateMemberRequest request) { memberService.update(id,request.getName()); Member findMember = memberService.findOne(id); return new UpdateMemberResponse(findMember.getId(), findMember.getName()); } 아래와 같이 하지 않은 이유가 있을까요?? @PutMapping("/api/v2/members/{id}") public UpdateMemberResponse updateMemberV2(@PathVariable("id") Long id, @RequestBody @Valid UpdateMemberRequest request) { memberService.update(id, request.getName()); return new UpdateMemberResponse(id, request.getName()); }
클래스의 상속과 관련된 다형성은 부모객체로 인스턴스를 생성하여 부모클래스의 메소드와 자식클래스 메소드 2가지를 업/다운캐스팅하여 자유롭게 호출할 수 있지만, 단일상속이라는 한계 때문에 다른 부모클래스의 메소드는 호출할 수가 없잖아요? 그래서 인터페이스가 존재하는 이유구요. 마찬가지로, 인스턴스를 생성할 때 다형성을 활용하여 인터페이스 객체(부모 객체)로 생성할 수는 있지만, 이것은 ISP(Interface Segregation Principle)원칙에 따라 detect(), report() 2개의 메소드를 호출하려면 Detectable, Reportable 객체 2개를 생성해야 하기 때문에 메모리가 효율적으로 관리되지 못하는거구요. 따라서 구상클래스인 FactoryCam에서 인터페이스 변수를 직접 생성하고 setter함수로 필요한 인터페이스 변수를 주입한 다음(Dependency Injection) , 주입당한 객체는 인터페이스에 의존하기 때문에(Reportable, Detectable) 동시에 기능이 다른 2가지 메소드를 호출할 수 있는거구요.(Dependency Inversion Principle) ... 과정을 이해하였지만 말로 풀어내니까 굉장히 장황하군요 사실 이 부분은 인터페이스 문법이라기보다는 디자인 패턴과 관련이 있지 않나싶습니다.
방향 그래프 무방향 그래프에 따라서 자료구조에 자료를 저장하는 방법이 다르다고 하셨습니다. 그런데 지금 이 문제에서는 방향그래프 아닌가요?? 간선,엣지들을 보면 모두 방향이 있는 거 같은데, 왜 무방향그래프를 저장할 때처럼 arraylist에 값을 저장하는지 모르겠습니다.

안녕하세요 강사님! 질문 드리기에 앞서 항상 좋은 강의 감사드립니다! 제가 강의를 수강하면서 의아한 부분이 있었는데요, 바로 OrderResponse에 List<ProductResponse> 를 추가하신 부분 입니다. 이에 따라 OrderResponse의 of() 메소드 안에서 order.getOrderProducts() 를 호출할 수 밖에 없게 되었는데요, 이때 페치조인을 하지 않는 이상 쿼리가 나가게 될 것 같습니다 (지연로딩) 저는 바로 이 측면이 개인적으로 잘못되었다 고 생각하는데요, JPA는 어떤 쿼리가 어느 타이밍에 나가는지를 파악하기 어려워서, 최대한 이 측면을 명확하게 해주는게 필요하다고 생각합니다. 그래서 저의 경우는 서비스 로직에서 사용되는 repository 메소드 들에서만 쿼리가 나가는 경우로 명확하게 제한을 해주는 편 인데요, 이런식으로 서비스 로직이 아닌(정확히는 그 안에서 사용되는 repository메소드) 다른 곳에서 지연로딩으로 인해 쿼리가 나간다면 - 어느타이밍에 어떤 쿼리가 나가는지를 코드만 보고 명확하게 파악할 수 없게 된다고 생각합니다. 그래서 결론적으로 저는 OrderResponse 안에서 order.getProducts()를 호출하여 List<ProductResponse>를 만드는게 적절하지 않다고 생각하는데요, 이부분에 대해 강사님의 생각을 말씀해주시면 감사하겠습니다! 감사합니다.
안녕하세요! 먼저 항상 좋은 강의 감사드립니다!\ 다름이 아니라, 저는 제목대로 , 테스트를 위해서 OrderSerivce의 createOrder의 파라미터로 registerDateTime을 파라미터로 받게 추가한 측면이 개인적으로 적절하지 않다고 생각 하여 질문글을 작성하였습니다. 파라미터를 사용하는 이유는 결국 외부로 부터 값을 받는다는 전제가 깔려있다고 생각하고, 이런 측면에서 보았을 때 요청값으로 시간 값을 받는다고 생각할 수 있습니다. 그렇게 생각을 했을때 개인적으로 2가지 정도의 의아한 점이 발생한다고 생각합니다. 클라이언트로 부터 넘겨받는 시간이 과연 등록 시간이라고 할 수 있는가? (network delay가 있을것 이기 때문) 그렇다고 Controller에서 now() 를 호출한 시간이라는 일종의 고정값을 받을거면 - 파라미터를 선언하는 의미가 있는가? 결론적으로 저는 createOrder의 파라미터로 registerDateTime을 선언하는것이 적합하지 않다고 생각합니다. 하지만 우리의 경우는 tdd로써 테스트를 위해 외부로 값을 추출하였는데 - 이러한 문제가 발생하였으므로, tdd 개발론이 과연 적절한 production code를 만드는게 기여하는가? 라는 측면에서 의문이 듭니다. 나아가 당연히 저의 미숙한 탓 이겠지만, 강의를 진행해주신 방식대로 온전한 비즈니스 로직을 작성하지 않고 , 테스트 - 개발 - 테스트 - 개발... 이런 플로우로 개발을 하는것이 과연 도움이 되는가? 도 조금 의아한 것 같습니다. 어쨌든 여기까지는 저의 순수한 개인적 생각인데요, 이런 부분에 대해서 강사님 께서는 어떻게 생각하시는지 말씀해주시면 정말 감사하겠습니다!

안녕하세요. 회원 탈퇴 기능을 개발하고 있습니다. 탈퇴하면 Users 테이블의 use_yn 값을 N 변경 후 14일 지나면 스케줄러로 관련 데이터를 다 지우도록 개발하려고 합니다. 스케줄러 작업 중에 있는데 테스트코드를 짜다가 막혀서요. 탈퇴 누를 때 use_yn 값을 변경하기 때문에 BaseEntity에 있는 upd_date가 알아서 변경일을 update 합니다. 근데 그래서 테스트 코드에서 upd_date 조작을 할 수가 없네요 ㅠㅠ 14일 지난 케이스로 만들어보려고 합니다. 스케줄러라 스케줄러에 파라미터를 보낼 수도 없고 이 경우에는 어떻게 테스트 하나요?

Java 에서 Final 만 사용할 수 있는게 외부 변수가 메모리에서 해제 되었을 경우, 가비지를 참조할 수 있는 것을 방지하기 위해서로 알고 있는데 코틀린은 이게 가능한게 아예 메모리를 통째로 떠와서 그런걸까요? ㅎㅎ 강의 영상에서 포획한다 라고 표현하신게 그런 의미 같아요!
