안녕하세요.실전예제 4 - 상속관계 매핑 11:05 부분에서 'json으로 말아넣는다'는 의미가 어떻게 넣는다는 의미인가요?

안녕하세요.@MappedSuperclass 어노테이션을 사용하는 BaseEntity 클래스는 아래와 같은 필드를 갖고 있습니다.CREATEDBY  CREATEDDATE  LASTMODIFIEDBY  LASTMODIFIEDDATE여기서 궁금한 점이 하나 생겼는데요.만약 처음에 100개의 클래스 중 100개 클래스 모두가 BaseEntity 클래스를 상속받아서 공통 필드를 사용하고 있습니다.그런데 운영중에 100개 중 50개의 클래스에서만 사용하는 공통 필드가 추가되면 이런 경우에는 어떻게 처리하면 좋을까요?자바에서 상속은 1개만 할 수 있어서 고민이 됩니다.50개의 클래스에 노가다로 필드를 입력해야 좋을지,,

안녕하세요! 강의 잘 듣고 있습니다 감사합니다.강의를 따라가다가 잘 안되는 부분이 있어서 질문글 하나 남겨봅니다.Gradle -> Tasks -> build -> cleanGradle -> Tasks -> other -> compileQuerydsl실행 시에 정상적으로 Q타입 클래스가 생성이 됩니다.그런데 이후에 테스트 코드를 돌려보면이런 오류가 뜹니다.이것저것 해보다가 build파일이 없는 상태에서(삭제 후에) 테스트를 돌리면 돌아가긴 합니다.정상적으로 빌드해서 돌려보고 싶은데 설정을 어떻게 바꿔야 할까요?https://drive.google.com/file/d/1H7Sz9Z994odDceIhuTp9S4bpfvhDjxAr/view?usp=sharing구글 드라이브 링크입니다.

안녕하세요, 값 타입을 불변 객체를 만들 때 궁금한 점이 생겨 질문드립니다. 상황을 가정해서 질문드리겠습니다.상황값 타입을 불변 객체로 만들어서 값을 수정하기 위해, 새로운 불변 객체를 만들어 엔티티의 필드값을 변경합니다.질문위 상황에서 "JPA 관점에서는 어쨌든 컬럼값이 변경되어야 하니까 변경 감지는 계속 일어나고 있다." 처럼 이해해도 괜찮을까요?

localhost로 바꾸고 jdbc:h2:~/datajpa로 작성하고 해도 저렇게 뜨네요권한도 755로 변경했습니다어떻게 해야 할까요?

안녕하세요비즈니스 메서드에 관해 궁금한 게 생겨서 질문드립니다.강의 중에 엔티티를 변경할 때는 Setter대신 비즈니스 메서드를 별도 작성하여 제공하라고 해주셨는데1) 등록이나 수정(save, update) 같은 것을 할 때 domain 쪽에 비즈니스 메서드를 작성하라는 뜻이 맞나요?2) 구글링을 해보니 빌더 패턴, 정적펙토리 메소드 라는 기술도 존재하던데 비즈니스 메서드를 포함한 3가지는 궁극적으로 하는일이 비슷하다고 생각하는데 다른가요?

 안녕하세요. 질문이 있습니다,@Id@GeneratedValue(...)private Long id; 이렇게는 사용해봤는데 처음에 =null 을 사용하신 이유가 궁금합니다.

우선 2개의 질문을 참고하였습니다.이것과이것입니다.  두개의 글을 종합해 보면, V1에서 Order리스트를 반환할때는 Lazy방식이기 때문에 Member객체가 프록시 객체이고, Jackson이 해당 해당 객체를 접근하는 순간 초기화한다는 것입니다. 그리고 해당 프록시 객체를 JSON으로 읽을수 있도록 도와주는 것이 하이버네이트5모듈이라는 것입니다. 여기서 궁금한 점이//강제 지연 로딩 설정 hibernate5Module.configure(Hibernate5Module.Feature.FORCE_LAZY_LOADING, true);이 코드입니다. 해당 코드는 강제 지연 로딩 설정이라고 하는데강의 21분 20초경 LAZY를 강제 초기화 한다고 나와있습니다.저는 위의 코드와 for (Order order : orders) { order.getMember().getName(); order.getDelivery().getAddress(); }이 코드가 같은 역할을 한다고 이해했습니다. 위의 두개의 코드를 삭제하면, 포스트맨으로 요청을 보냈을 때,Member, orderItems, Delivery에는 null 값이 들어갑니다. 두개의 코드중 하나를 넣으면 요청을 넣었을때 Member, orderItems, Delivery에 실제 값이 들어가게 됩니다. 하지만 위의 두 글을 종합한 내용을 보면Jackson이 해당 해당 객체를 접근하는 순간 초기화라는 내용이 있습니다. 그렇다면 이미 초기화 된 프록시 객체일텐데 왜 위의 강제초기화 코드를 넣어야 실제 값이 들어가게 되는지 궁금합니다. jackson이 프록시 객체에 접근할때 초기화가 되어서 두 코드를 넣지 않아도 null이 아닌 실제 값이 나와야하는 것 아닌가요?   글이 너무 길어 죄송합니다..ㅠㅠ   

 안녕하세요. 선생님따라서 코딩중인데 구글링결과대로 시도해봐도 딱히 해결되지 않아서 질문 남겼습니다... 제목 그대로 import 자체가 되지 않아요 ㅠ

<요구사항>사용자가 맘에 드는 장소를 저장 할 수 있다.Place 에서 FavoritePlace 를 Join 하고 싶다.<관계도>Place(1) - (N)FavoritePlace(N) - (1)User<질문내용>Place 에는 FavoritePlace 필드가 없기 때문에 join 을 사용 할 수 가 없어서 , 양방향 매핑을 이용 하였습니다.이럴 경우 양방향 매핑을 사용하는것이 맞는지 궁금하고,FavoirtePlace 의 상태가 변경될때의,연관관계 편의메서드를 구현하였는데 흐름은Place 가 가지고 있는 list 를 순회하여, 바뀌기전의 FavoirtePlace 를 삭제하고 새로운 FavoirtePlace 를 add 하는 로직을 선택하였습니다.그러다보니 수많은 List 중 FavoirtePlace 하나를 순회하여 찾아 제거 하는 작업이 조금 버거울거같다는 고민이 생겼습니다.제가 이해한 양방향을 써야 하는 상황이 이부분이 맞는지, 위와 같은 상황에서 어떻게 해결하는게 조금 더 현명할지 조언 듣고 싶습니다! 감사합니다

 BookMemoryRepository랑 BookMysqlRepository에 @Repository를 모두 붙이면 빨간줄이 강의상에선 나는데 저는 이상이 없는 데 혹시 스프링 버전 차이인건지 궁금합니다.

학습하는 분들께 도움이 되고, 더 좋은 답변을 드릴 수 있도록 질문전에 다음을 꼭 확인해주세요.1. 강의 내용과 관련된 질문을 남겨주세요.2. 인프런의 질문 게시판과 자주 하는 질문(링크)을 먼저 확인해주세요.(자주 하는 질문 링크: https://bit.ly/3fX6ygx)3. 질문 잘하기 메뉴얼(링크)을 먼저 읽어주세요.(질문 잘하기 메뉴얼 링크: https://bit.ly/2UfeqCG)질문 시에는 위 내용은 삭제하고 다음 내용을 남겨주세요.=========================================[질문 템플릿]1. 강의 내용과 관련된 질문인가요?

(예)[질문 내용]Joincolumn의 name속성은 그저 member테이블의 조인컬럼의 컬럼명을 지정하는것뿐 team과 매핑하는것과는 관련이없다. member와 team을 연관관계맺는것은 referencedColumnName속성이 하지만 이것을 생략하면 자동으로 team의 pk값으로 연관관계를 맺어줘서 생략한다. 이게 맞을까요?

안녕하세요, 주제와는 좀 다른 질문인데요.강의하시는거 보면 맥에서 intelij 를 상당히 잘 활용하신다고 느꼈습니다. 특히, 9강에서 ide 화면을 4분할로 빠르게 구성하는게 인상적이었는데, 혹시 그 방법과 단축키 알려주실수 있나요?

따라치기에 바쁘고 코드를 적으시는데 이해못하면 잘못 듣고있는건가요? 자바 강의는 다 들었는데 뭘하시는지를 모르겠고 따라적기만 하고있습니다..

해당 에러를 고치기 위해 세팅의 자바 컴파일러 버전을 11로 바꾸었는데 이렇게 진행하여도 괜찮은가요??

Caused by: org.h2.jdbc.JdbcSQLSyntaxErrorException: Cannot drop "PRODUCT" because "FKR3MKF1FYVW50W5N52XQ1B8A4B" depends on it; SQL statement: 참조때문에 drop이 안되어서 create를 다시할떄 문제가 생기는 것같습니다.

강사님 새해 인사 조금 늦졌지만 건강하세요 강사님의 지식을 뛰어난 전달력으로 강의 해주셔서 고맙습니다.. 

강의 잘 듣고 있습니다! 이것저것 해보다가 궁금한게 생겼어요. 19번째 줄이 실행되는 순간 customerList의 fee 값이 바뀌어야 하는거 아닌가요? 20번째 줄을 안쓸때는 아래처럼 fee값이 안바뀐채로 출력되는데 챈 50 0 레 45 0 모 40 0 벤 20 0 제 10 020번째 줄을 쓰니까 이렇게 나오는 이유가 궁금합니다!챈 50 2000 레 45 2000 모 40 2000 벤 20 0 제 10 0
