안녕하세요, 강의 잘 듣고 있는 학생입니다. 다름이 아니라 "스프링 통합 테스트"부분에서 기존 메모리에서 진행하던 테스트를 DB랑 연동해서 진행하는 부분에서, 테스트로 진행한 name이 들어가지 않는 중입니다. 테스트 돌릴시 fail은 따로 뜨지 않고, 잘 넘어가는 중입니다. 그리고 id 시퀀스도 하나 증가해서 잘 되는데 name이 등록이 되지 않더라고요. 따로 프로젝트를 실행해서 웹페이지에서 넣으면 문제없이 동작하는 중입니다. (따로 id 시퀀스가 증가가 잘되는 것을 확인한게 웹페이지에서 넣고, 테스트로 돌리고, 다시 웹페이지에서 넣었을시, id가 8,10이 뜨는걸로 확인했습니다.) 어떻게 수정하면 될까요..ㅎ?
안녕하세요! 강사님께서 em.clear를 한순간 끈건 아니지만 영속석 컨텍스트안에 완전히 다 지우고 새로 만든거라고 하셨는데 refMember.getUserName();을 한 순간에 DB를 조회해서 쿼리가 나가서 해당 클래스가 영속성 컨텍스안에 들어가는걸로 알고 있습니다. 근데 아직 DB 조회를 하기전( refMember.getUsername()을 하기전 )이라 영속성 컨텍스트안에 해당 클래스가 없는거 아닌가요? 항상 강의 잘보고있습니다 . 감사합니다!!
예전에는 service단에서 trasaction을 걸어서 했었는데 repository에 기본적으로 @trasantional이 적용되어있나요?? 그렇기 때문에 db에서 쿼리를 해올수잇는건지 궁금합니다 ㅎㅎ 추가적으로 repository에 transation이 걸려있다면 왜 service 클래스에 이중으로 @trasational 어노테이션을 거는건가요?
h2 데이터베이스에는 값이 제대로 들어가 있는데 회원 목록에 들어가면 오류가 뜨네요.. 그래서 회원 가입에서 등록한 값은 값이 제대로 들어오는 지 확인하려 하니 등록 버튼을 누르면 똑같이 Whitelabel Error Page 가 뜹니다.. 재부팅, db 삭제 후 재생성, 8080 포트 삭제 후 재시작, gradle 리프레쉬, 질문 확인, 코드 재확인 등 여러가지 시도해봤지만 해결이 되지 않아 질문드립니다ㅠㅠㅠ <오류 코드> org.h2.jdbc.JdbcSQLNonTransientConnectionException: Database may be already in use: null.

jpashop.mv.db파일이 생성되지 않고 , IO Exception: null [90028-200] 90028/90028 가 뜨는데 제가 이전 수업에서 사용했던 test.mv.db파일이 있어서 jpashop.mv.db파일이 생성이 안되는건지 모르겠습니다. 도움주시면 감사하겠습니다 ㅜㅜ
하이버네이트 모듈이 기본상태일때 orderItem을 DB에서 자꾸 쿼리하는게 로그상에 보여서 질문드리는데요 이 상태에서 Order엔티티에 "orderItems" 는 1대다 관계로 묶여있어서 당연히 기본이 lazy로딩이라서 orderItems에 접근하지 않는한 DB에서 쿼리하지 않을줄 알았는데 쿼리가 나가더라구요 ..? 왜 그런걸까요 ..?? 제가 배운 내용으로는 이해가 가지 않아서 ㅠㅠ
질문게시판을 많이 사용하셔서 여기다가 올립니다 죄송합니다. 학습을 이클립스로 하시는 분들을 위해 초기 세팅법을 포스팅해봤습니다. - 저도 오류잡느라 애먹었는데 다른분들에게 최대한 도움을 드리고자 합니다. https://glasowk.tistory.com/10 고생하시고 즐거운 학습하세요 ~~ 좋은 강의 감사합니다. 백기선님 화이팅 !!
안녕하세요 insert 벌크 쿼리에 관해 질문있습니다. 강의에서 말씀해주신 대로 해보니 delete와 update의 경우 한번에 처리되는 것을 확인할 수 있었습니다. 문제는 Insert 였습니다. 저는 MySQL 를 사용하면서 IDENTITY 전략을 사용해왔었는데 MySQL의 경우 벌크 INSERT 쿼리를 날리기 위해서는 찾아보니 Batch Insert를 사용하기 위해서는 IDENTITY 전략이 아니라 TABLE 전략을 사용해야 한다고 하더라구요. 제가 궁금한 점은 아래와 같습니다. 1. 다른 ENTITY들은 IDENTITY 전략을 사용하고 Batch Insert가 필요한 특정 ENTITY만 TABLE 전략으로 변경해도 괜찮을까요? 2. 실무에서는 INSERT 쿼리를 한 번에 날리기 위해서는 어떤 방식을 사용하나요?? 감사합니다 :) 2.
선생님 안녕하세요! 매번 정말 좋은 강의 감사드립니다ㅋㅋㅋㅋ 저 진짜 웹 하나도 모르는 생짜 초보인데, 갑자기 자바 스프링 실무에 투입되어서 넘 힘들었거든요ㅠㅠ 바로 선생님 강의 패키지로 싹 다 결제하고, 하나씩 들으면서 감을 잡고 있습니다. 제 구세주십니다. 감사합니다!! (다음달 월급 들어오면 선생님께 다 갈 예정입니다..?!ㅎㅎㅎ) 최근에 JPA Mapping 관련해서 공부하고 또 실무에 적용해 보고 있는데요, 현재 제가 하는 프로젝트에서는 음식 재료 바구니 기능을 구현해야 합니다. 요게 유저 - 대바구니 - 소바구니 - 음식 재료로 이어지는 계층적 구조이고, 유저 하나가 여러 대바구니, 대바구니 하나가 여러 개의 소바구니, 소바구니 하나가 여러 개의 음식 재료를 포함하는 구조입니다. 각 자식들은 하나의 부모에만 속하게 되어 있구요. 쌤 강의 듣고 일단은 ManyToOne 단방향 매핑으로 각각을 1:N으로 걸어줬는데요. 특정 대바구니 id 아래에 있는 소바구니 (혹은 그 소바구니 아래에 있는 음식 재료까지)를 조회하거나, 특정 소바구니 id 아래에 있는 음식 재료들을 조회하거나 하는 쿼리가 가끔 필요한 상황입니다. 또 대바구니 하나를 삭제하면 그 밑에 소바구니는 싹 다 지워지고, 소바구니 하나를 지우면 그 바구니에 음식 재료들은 싹 다 지워져야 하는 상황이구요. 즉 DELETE시 CASCADE + 가끔 부모 아래에 있는 자식을 부모 id로 조회하는게 필요한 상황입니다. 요럴때 양방향 매핑이 필요할까요?! 현재 고민하고 있는 옵션은 - 단방향 매핑으로 계속 가되 ON DELETE CASCADE를 DB TABLE에 걸어줘서 부모 삭제시 자식도 삭제되도록 만든다. - 아니면 양방향 매핑으로 해주고 mappedBy 있는쪽에 CASCADE.ALL, orphanRemoval 걸어준다. 인데요, 1) 성능이 단방향, 양방향 매핑에서 차이가 많이 나는지 궁금합니다. 2) 그냥 단방향 매핑으로 모든 거 처리하고, 필요할때만 sql join query 날려서 join해서 불러오면 되는거 아냐? 라는 생각도 드는데요.. 그리고 추가 질문으로, 언제 양방향 매핑을 사용하는게 좋은지 잘 모르겠습니다. 양쪽에서 참조할 일이 있을 때라고 강의에서는 말씀해 주셨는데 잘 안 와 닿더라구요. 혹시 실무 예시를 좀 들어 주실 수 있으실까요? 감사합니당!!!
시점 : 26:25 org.hibernate.dialect.Oracle12cDialect 로 변경시 쿼리가 rownum계열이 아닌 Hibernate: /* select m from Member as m */ select member0_.id as id1_0_, member0_.name as name2_0_ from Member member0_ fetch first ? rows only 와 같이 나오는데 왜그런지 궁금합니다.
안녕하세요 영한님! 강의 내용 중 궁금한 점이 있어 질문 드립니다. Team refTeam = em.getReference(Team.class, 1L); refTeam.getName(); 을 하게되면 Proxy가 비어있으므로 1. 영속성 컨텍스트에 초기화 요청을 보내고, 2. 영속성 컨텍스트가 DB를 조회해 3. 실제 엔티티 객체를 생성 은 이해가 되었습니다. 그럼 여기서 영속성 컨텍스트가 실제 엔티티 객체를 생성하고 Proxy의 target에 연결을 해줄 뿐이지, 1차 캐시에 실제 엔티티가 저장되는 것은 아닌 건가요? 1차 캐시에는 'Proxy 객체만' 있고 Proxy의 target을 통해 실제 엔티티를 접근할 수 있는 건지 궁금하여 질문 드립니다! 감사합니다.
안녕하세요. 연관관계 주인이 아닌 List로 구현된 members에서 궁금한 점이 있습니다. 먼저 지금까지 이해한 바로는, @Entity 애노테이션과 ddl-auto 속성에 의해서 @Entity를 가진 클래스의 필드들이 해당 테이블의 attribute로 만들어지는 것으로 이해했습니다. 1. @Column이 DB 테이블의 실제 컬럼 이름과 매핑을 짓는 용도라고 이해했는데 @Column을 생략해도 DB상에 해당 컬럼이 생성된 것을 확인했습니다. 이 경우, 컬럼은 생성됐지만 매핑은 이루어지지 않은건가요? 2. Team 클래스의 members 어레이리스트는 Team 테이블의 attribute로 등록되지 않는 이유가 뭔가요? 물론, 데이터베이스 상에서 하나의 attribute에 하나의 값을 가져야 하는건 맞지만 이게 컬렉션으로 구현된 필드는 JPA에서 자동으로 attribute이 아니라고 인식하는 건가요?
