ORDERS와 ORDER_ITEM의 관계는 하나의 주문 안에, 주문된 여러가지 아이템(book,album,movie등)이 있을 수 있기 때문에 1:N인 것 이 맞나요 ? OrderItem과 Item의 관계가 잘 이해 가지 않아서 찾아보다가 https://www.inflearn.com/course/lecture?courseSlug=ORM-JPA-Basic&unitId=21699&category=questionDetail&tab=community&q=805804 이 답변을 보고 헷갈리는 부분이 있는데요. Book을 n번 주문할 수 있기 때문에 1:N이라고 하셨는데 이 말은 즉, Book이라는 아이템 안에서도 주문된 여러가지 책(일본 책, 독일 책, 한국책) 이 있을 수 있기 때문에 1:N이라는 말일까요? 어떤 Member가 어떤 주문을 했는지 Order를 참고하는 것과 어떤 Order가 무엇을 구매했는지 Order_Item을 참고하는 것이 같은 맥락이라고 생각하는데 전자는 잘못된 설계고 후자는 괜찮은 설계인 이유는 무엇일까요?
public class Team2 { @Id @GeneratedValue @Column(name = "TEAM_ID") private int id; private String name; @OneToMany @JoinColumn(name = "MEMBER_ID") private List<Member> members = new ArrayList<>(); } public class Member2 { @Id @GeneratedValue() private Long id; @Column(name = "name") private String username; @ManyToOne(mappedBy = "members") private Team team; } 강의를 듣다가 외래키를 Team에 두면 안되는 것인가? 하고 혼자 코드를 작성해보았는데요. @ManyToOne은 mappedBy옵션을 지원하지 않는 걸로 봐서 1:N에서 N쪽이 외래키가 있어야하고, 연관관계의 주인이 되어야하는 것 같은데 연관관계의 주인이 되는 외래키는 어떤 방식으로 설정해주나요 ?
안녕하세요 선생님 다름이 아니라 제가 작성한 코드가 정답처리가 되었는데 이 코드는 정답이 되면 안되는 코드가 아닌가 해서 여쭤보고 싶어서 질문글 남깁니다. 예를들면 첫번째 문제에서는 CBA 순서로 무조건 짜야하지만 제 코드에서 str1 은 꼭 순서를 지켜야 하는 값이고 str2는 C의 순서를 알 수 없는데 정답처리가 되어서 제가 작성한 코드가 제대로 정답이 맞는건지 궁금해서 질문글을 남깁니다!
둘 다 null을 허가하지 않는 다는 의미로 쓰이는 것 같은데 어떤 차이가 있는 건가요 ? @EnumType 애노테이션을 제거하고 멤버를 추가해도 @EnumType.Ordinal 옵션을 적용 한 것처럼 Integer로 컬럼을 만들고 user = 0, admin=1 으로 잘 저장하던데 @EnumType은 어떤 역할을 하는 것인가요? EnumType.String이 필수로 써야할만큼 EnuType.Ordinal은 안좋은 옵션같은데 Default가 String이 아니라 Ordinal인 거는 따로 무슨 이유가 있는 건가요 ?
1차 캐시, 쓰기지연, 더티체킹(스냅샷), 지연로딩 영속성 컨텍스트의 특징이 이정도인 거 같은데 더티체킹은 엔티티(객체)를 컬렉션에서 관리하듯이 도와줘서 수정측면에서 도움이 많이 되는 것 같긴 한데 1차캐시나 쓰기지연 로딩은 디비에 데이터 몇 번 덜 접근한다고 해서 큰 차이 없을 것 같은데 성능적인 측면에서 많이 도움 되나요? 실무를 해본 적이 없어서 제가 잘 모르는 것일까요 ?
DB 접근 2편이나 활용1편에서는 Gradle을 사용해서application.properties를 통해 h2를 설정하고 build.gradle을 통해서 라이브러리를 받아왔던 것 같은데 이번 강의에서는 xml파일들을 사용해서 상당히 어색한데요. 최근에 Gradle을 많이 사용한다면 xml로 설정하는 방법을 따로 공부할 필요는 없을까요?
Junit5로 테스트를 생성해서 그런지 Test애노테이션에 expected 라는 옵션이 없어서 @Test() public void 상품주문_재고수량초과() throws Exception { //given Member member = createMember(); Item book = createBook(10000, 10, "시골 JPA"); int orderCount = 11; //when Assertions.assertThatThrownBy(() ->orderService.order(member.getId(), book.getId(), orderCount)) .isInstanceOf(NotEnoughStockException.class); } 이렇게 만들어서 돌렸는데 테스트가 통과했다면 그냥 넘어가도 되는 것일까요? @Test() public void 상품주문_재고수량초과() throws Exception { //given Member member = createMember(); Item book = createBook(10000, 10, "시골 JPA"); int orderCount = 11; //when Assertions.assertThatThrownBy(() ->orderService.order(member.getId(), book.getId(), orderCount)) .isInstanceOf(NotEnoughStockException.class); fail("재고 수량 부족 예외가 발생해야 한다."); } 이렇게 돌리면 재고 수량 부족 예외가 발생해야 한다. java.lang.AssertionError: 재고 수량 부족 예외가 발생해야 한다. 라는 예외가 발생했습니다.
public int getTotalPrice() { return orderPrice * count; } public int getTotalPrice() { return getOrderPrice() * getCount(); } 주문 아이템의 가격을 반환해야할 때 당연히 위처럼 코드를 작성해야겠다고 생각했는데, 강의를 보니 아래처럼 하시더라구요 결국 같은 값을 반환하는 것 같은데 어떤 차이가 있는지 알 수 있을까요 ?

안녕하세요 현재 파이썬을 공부중인 학생입니다. 이전까지는 태그의 값을 텍스트로 출력하고 있었는데 태그안에 속성값을 텍스트로 출력할일이 생겨서 여러 방면으로 검색 및 시도를 해보고 있는데 잘 안되네요 여기서 data-taitle="BLACK(99)" 의 BLACK(99) 를 텍스트로 출력하고 싶습니다. 어떻게 하면 될까요? #python

안녕하세요! 제가 강의를 다 듣고 난 뒤 추가로 공부를 해볼 생각으로 catalog-service 에서 example-catalog-topic 를 받은 뒤 상품의 개수를 파악 후 재고 유무의 따라 order-service 에 주문 상태를 전달 해주는 example-order-topic 를 만들어 구독 중인 order-service 에서 example-order-topic 에서 전달 받은 주문 상태를 업데이트 하는 로직을 구현하려고 했습니다. 로컬에서 order-service 와 catalog-service 의 consumer groupId 를 consumerGroupId 로 통일해서 사용 했을 때는 괜찮았으나, docker 에 올리니 example-order-topic 이 생성은 됐으나 구독 및 전달이 되지 않더라구요.... 혹시나 해서 order-service 의 consumer groupId 를 consumerGroupId2 로 변경하여 docker 에 올리니 정상 작동이 됩니다. 혹시 각각의 service 는 groupId 를 다르게 해주어야 할까요??
author이랑 isbn이 null로 나와있는데 싱글테이블에서 Album이랑 Movie에 관련된 컬럼은 안나오고 딱 Book이랑만 관련된 author이랑 isbn 만 null로 표시됐는데 이건 JPA가 Book인 걸 알아서 그것만 표시해주는건가요 ?? 어떻게 author이랑 isbn만 표시해주게 되는건지 궁금합니다 ..
안녕하세요 나도코딩님 오늘도 열심히 공부중인 학생입니다 ㅠㅠㅠ 복수전공 과목 중 자바로 배우는 자료구조를 수강중인데 사전에 자바 공부도 없이 듣는 수업이라 도통 무슨 소린지 이해가 가질 않네요.. 그래서 현재 고급편 결제하고 섹션9 추상클래스 까지 들은 상태인데 뒤로 갈수록 내용이 어려워져서 복습한다고 속도가 너무 늦어지는 상태에요.. 자료구조 내용을 이해하려면 일단 어떤 파트를 필수적으로 빨리 들어야 하고 어떤 파트는 빼도 되는지 알려주실 수 있을까요??ㅜ 답변 주시는데 도움이 될 지 모르겠지만 교재 한 챕터에 {자바 데이터 타입(기본타입, 참조타입), 제어문(조건문,반복문), 메소드(호출문,메인), try문} 이렇게만 존재하긴 하는데 중간중간 책에는 없는 추상클래스, 입력문 같은 파트도 보여서 감이 안잡히네요..
안녕하세요~ 강사님, 인터페이스(후반전) 강의를 듣고 있는데, 왜 인터페이스 변수를 만드는지 이해가 가지 않습니다. 수업 내용에서 FactoryCam이 인터페이스 Detectable과 Reportable을 구현하여 인터페이스에 있는 메소드를 FacstoryCam에서 구현해야한다는 것은 이해했습니다. 그리고 다른 클래스의 detect 메소드와 report 메소드를 호출하는것이라서 public void detect(){detecter.detect();} 이고, detecter은 객체이잖아요. 여기서 막힙니다. 이 객체랑 인터페이스 변수랑 무슨 상관인지? FactoryCam 의 인터페이스 변수를 생성해서 변수에 값 저장하는 걸로 하면 되지 않는지? 왜 인터페이스 변수를 선언해서 거기다가 값을 저장하는지, 잘 이해가 안 됩니다.... ㅠㅠ 그리고 추가로, 인터페이스로 다중 상속이 가능하다고 하셨는데, 수업 내용 중 어떤 것이 다중 상속이 되고 있는지 파악하기가 어렵습니다. 혹시, 다른 클래스의 메소드를 호출할 수 있는 부분때문에 다중 상속이 가능한 것인가요? 후반부로 갈수록 어렵네요 ㅠㅠ
