category와 item 은 서로 다대다 관계인데, 관계형 db는 다대다관계인경우 중간테이블을 설정해야 해서 category_item테이블이 온다 라고 이해하면 될까요? 앞으로 추후 플젝 할때 다대다 관계이면 무조건 중간테이블을 설정해야지만 정상작동을 하는건지도 궁금해요

자바 ORM 표준 JPA 프로그래밍 - 기본편
회원을 수정하고, 회원의 닉네임이 중복되는 경우를 검증하고 싶었습니다. 더티체킹은 트랜잭션이 종료됐을 때 영속성 컨텍스트에서 변경된 것이 있는지 확인하고 변경된 것을 확인되면 업데이트 되는 것으로 알고 있는데요. @Transactional public void update(Long id, String name) { Member member = findOne(id); member.setName(name); validateDuplicateMember(member); } private void validateDuplicateMember(Member member) { // NullPointerException 발생 X List<Member> findMembers = memberRepository.findByName(member.getName()); if (!findMembers.isEmpty()) { throw new IllegalStateException("이미 존재하는 회원입니다."); } } 제가 의도한 목적은 다음과 같습니다. 회원을 조회 -> 영속성 컨텍스트 영속상태 회원 객체에 대한 이름을 변경 -> 트랜잭션 종료 시 더티체킹 예상 현재 객체 전달 전달 된 회원의 이름을 가진 회원을 조회 중복 시 Rollback, 아니라면 commit 후 더티체킹 이후 회원 엔티티 수정 하지만 중복이 아님에도 중복 예외가 발생하길래 log를 확인해본 결과 List<Member> findMembers = memberRepository.findByName(member.getName()); 를 수행하기 전에 flush()가 되는 부분을 확인 할 수 있었습니다. 의심되는 부분은 4번에서 회원을 조회하는 과정에서 쿼리를 수행해야해서, 그 과정에서 쓰기 지연 저장소에 있던 쿼리들이 flush() 된 것이 아닌가 하는 의심이 듭니다. 그럼 제가 원하는 목적을 수행하기 위해서는 메서드를 아래와 같이 변경해야만 하는지.. @Transactional public void update(Long id, String name) { validateDuplicateMember(name); Member member = findOne(id); member.setName(name); } private void validateDuplicateMember(String name) { // NullPointerException 발생 X List<Member> findMembers = memberRepository.findByName(name); if (!findMembers.isEmpty()) { throw new IllegalStateException("이미 존재하는 회원입니다."); } } 다른 질문에서 중복 검증 시 영한님의 다음과 같은 답변을 확인 할 수 있었는데요. @Transactional public void update(Long id, String name) { Member member = findOne(id); validateDuplicateMember(member); member.setName(name); } private void validateDuplicateMember(Member member) { // NullPointerException 발생 X List<Member> findMembers = memberRepository.findByName(member.getName()); if (!findMembers.isEmpty()) { throw new IllegalStateException("이미 존재하는 회원입니다."); } } 이 부분은 변경되기 전이고 이미 등록된 상태의 Member를 가져오는 것이기 때문에 회원 이름 수정 시 중복 가능성에 대한 예외를 검증하는 것이 아니지 않나 하는 생각이 들어서 질문드립니다..!

실전! 스프링 데이터 JPA
안녕하세요, [메소드 이름으로 쿼리 생성 메소드] 강의 중 메소드 이름을 분석해서 JPQL 쿼리 실행 부분에 질문이 있습니다. 예를 들어 findByUsernameAndEmail()과 같이 이름을 정의하였을 때, 내부적으로 SQL을 어떻게 생성하는지 궁금합니다. '자바 ORM 표준 JPA 기본편' 강의에서 em.persist()를 실행하면 영속성 컨텍스트 내부에서 SQL을 생성하고, SQL 쓰기 지연 저장소에 저장하는 것을 설명해주셨습니다. 즉, 컴파일 시점이 아닌, 런타임 시점 동적으로 쿼리를 생성하는 것으로 이해하였습니다. 위에서 말씀 드린 findByUsernameAndEmail()과 같은 경우 jpql로 변환되어서 쿼리가 실행된다고 말씀해주셨습니다. 어떠한 방법을 통해, 내부적으로 어떠한 로직을 거쳐 런타임에 jpql로 변환이 될 수 있는지 궁금합니다. 감사합니다.

안녕하세요! 선생님의 강의를 너무나 재밌게 잘 듣고 있는 수강생입니다. 현재 배포 준비하기 전까지 강의를 들었는데요, 강의와 함께 구현된 기능 외에 추가적인 기능을 구현해보고 싶어서 질문드립니다! 유저의 대출 기록을 보여준다거나 하는 다양한 기능들을 프론트엔드 부분에서도 추가하여 만들어보고 싶은데 저희 프로젝트의 index.html, main.d4f24480.js 등을 둘러봐도 어떻게 건드려야 할지 전혀 감이 안오더라구요! 목록에서 유저들 정보가 뿌려지는 부분의 코드도 못찾아서요ㅠ 괜찮으시다면 저희 프로젝트에서 프론트적인 부분을 어떻게 만드셨는지나, 동작하는 큰 흐름 혹은 간략한 설명이라도 부탁드려도 될까요??ㅜㅜ 좋은 강의 만들어주셔서 감사합니다:)

Practical Testing: 실용적인 테스트 가이드
안녕하세요! PresentationLayer 테스트(1) 수강하며 문득 든 궁금증이 있어서 질문을 드립니다. 강의 36:03 쯔음에서 Product 가 하나도 저장되지 않은 상태를 테스트할 때, 새로운 Product 의 최신 번호를 조회하게 되면 "001" 이 되는 과정에서 ActiveProfile 을 test 로 해주지 않아 DB에 데이터가 임의로 들어가 있던 것 때문에 테스트 통과가 되지 않았는데요. 그러면 그 전에 진행했던 createProduct 테스트의 given에서 Product 를 하나 저장한다면 여기서도 ActiveProfile 이 test 이지 않았던 상태였기 때문에 저장한 데이터가 4번째 데이터가 되어야 하고 그랬다면 테스트 통과가 안 되어야 하는게 맞지 않았나..? 하는 갑작스러운 의문이 들었습니다. 제가 놓치고 있는게 무엇일까요?

Practical Testing: 실용적인 테스트 가이드
안녕하세요 강사님, 우선 꿀팁 가득차있는 강의 너무너무 잘 들었습니다. Spring REST Docs 관련해서 질문이 있습니다. 강의에서는 이미 레이어별로 테스트 코드를 작성하였는데요. Spring REST Docs 적용하면서 별도의 ProductControllerDocsTest 클래스를 만들어 createProduct()의 동일한 테스트 코드가 문서를 위해 또 들어가는 것 같아 관리해야할 테스트 코드가 두배가 되는게 아닌가 궁금해서 질문드립니다! 실무에서는 이렇게 테스트 전용 테스트코드와 문서용 테스트 코드를 별도 분리하는지, 아니면 둘을 함께 포함하여 하나로 작성하는 방식인가요? ~ 감사합니다.

JPA를 활용할때 JPA코드로 만들어진 테이블이 아닌 기존에 DDL로 만들어진 테이블 조회도 가능 할까요 ? - 이건 아직 제가 조회 부분을 안봐서 질문하는것일수도 있네요 ㅠ 실행하면서 JPA로 만들어진 테이블이 구성되는데 그럼 매번 실행할때마다 테이블을 지우고 생성되는건지 아니면 중복테이블을 체크하고 생성되는것일까요 ? ManyTOMany를 실무에선 안쓴다는 말이 다대다 구성을 안한다는 말씀이신거 같은데 그럼 다대다와 같은 경우를 중간테이블로 두어서 1대다 형식으로 구성하는 방안이 좋을까요 ?

public class student { public int score; public int getScore() { return this.score; } } 위와 같은 코드가 있고 연관관계 매핑이 되어있어 현재 프록시 상태라고 가정했을 때 점수를 얻기 위해 student.score를 사용 하면 영속성 컨텍스트로부터 초기화를 받지 못하고, student.getScoret()를 하면 초기화를 받는 건가요 ? 만약 프로퍼티 접근을 사용했을 때 초기화를 받지 모한다면 studnet.score 안에는 무슨 값이 들어있게 되는 건가요 ?

JPA에서 제공하는 어노테이션을 이용해 Java 코드로 정의된 엔티티 클래스 간 연관 관계를 설정하면, JPA가 이 코드를 기반으로 테이블을 생성하게 된다. 이때, Member과 Team 엔티티 클래스 중 하나는 무조건 연관 관계 주인으로 지정해주어야 한다. 기본적으로 데이터베이스의 테이블은 외래 키를 통해 두 테이블 간의 관계를 설정할 수 있고, 한 쪽의 테이블에만 (관계를 맺을 테이블에 대한) 외래 키가 존재하면 JOIN을 통해 자유롭게 양쪽 테이블을 참조할 수 있다. (→ 단방향, 양방향(단방향*2) 연관 관계라는 개념이 테이블 간에는 존재하지 않는다.) 그런데 Member 엔티티 클래스의 필드에 member_id, name이 있고, Team 엔티티 클래스의 필드에 team_id, name 존재하고, 일대다 연관 관계를 JPA 통해 설정했을 때 JPA가 매핑 정보를 기반으로 테이블을 생성하는 상황을 생각해본다. JPA는 기본적으로 MEMBER 테이블, TEAM 테이블을 생성할 것이다. 그리고 MEMBER 테이블에는 member_id, name 컬럼이, TEAM 테이블에는 team_id, name 필드가 컬럼이 존재할 것이다. 그리고 JPA를 통해 설정한 연관 관계 또한 두 테이블에 반영해야할텐데, 이를 위해선 두 테이블 중 하나에 (관계를 맺을 테이블에 대한) 외래 키 필드를 추가해야 한다. 외래 키를 통해 테이블 사이의 관계를 설정할 수 있기 때문이다. 그런데 JPA는 이 외래 키 필드를 어느 테이블에 추가해야할지 자체적으로 결정을 내릴 수 없다. 회원 테이블에 팀 테이블로 접근할 수 있는 외래 키 필드를 생성하는 것이나 팀 테이블에 회원 테이블로 접근할 수 있는 외래 키 필드를 생성하는 것이나 결국 (단방향/양방향 연관 관계 개념 자체가 없는) 데이터베이스 테이블 입장에선 차이가 없기 때문이다. 그래서 JPA를 이용해 연관 관계를 지정해주어야, JPA가 어떠한 엔티티가 다른 엔티티를 참조하는 주체가 되는지 파악할 수 있고, JPA가 테이블을 생성할 때 다른 엔티티를 참조하는 주체 엔티티와 매핑될 테이블에 외래 키 필드를 추가할 수 있게 된다. Member, Team와 같은 다대일 연관 관계를 양방향으로 설정한 후, Team을 연관 관계의 주인으로 지정했을 때, Team 수정 시 모든 Member를 향한 불필요한 (UPDATE 등의) 쿼리가 발생할 수 있다는 게 잘 다가오지 않습니다... ㅠㅠ Member를 연관 관계의 주인으로 지정했을 때 Team 수정하는 경우와 비교해서 조금 더 자세히 설명해주시면 정말 감사하겠습니다!

Practical Testing: 실용적인 테스트 가이드
안녕하세요~ 양방향 매핑을 사용하면 엔티티 간의 결합도를 높이기 때문에 가급적 단방향으로 만들면 좋다는 의견도 많은 것 같더라구요. 심지어는 양방향 매핑을 만들어야 한다면 엔티티가 아니라 id 값을 넣어서 참조를 하는게 더 좋다는 의견도 있구요. 강의에서는 양방향 매핑을 사용하셨는데 실무에서도 자주 양방향 매핑으로 설계하시나요? 사용하신다면 이러한 단점이 있지만 편의성이 더 크기 때문인가요?
