안녕하세요 이 강의를 본격적으로 듣기 전에 자바강의를 충분히 이해하고 싶습니다 그래서 이것이 자바다 와 자바의 정석중에 고민이 됩니다 자바의 정석은 서점에 가도 밀봉되어있어 책 내용을 알수가없어서 고민이됩니다. 각자의 장단점이 뚜렷하겠지만 혹시 선생님이 추천해주실만한 자바 강의가 있을까요? 그리고 자바를 공부하는데 어느 부분이 제일 필요한지도 궁금합니다

안녕하세요. 현재 김영한님의 JPA관련 강의들을 수강하면서 기존 프로젝트에서 JPA 로 변경시 문제가 있어 문의드립니다.배운 것을 실적용할 경우 문제는, 테이블 설계시 제약사항이 테이블 간 연관관계 설정을 하지 않는 것입니다.이 경우 도메인클래스를 어떻게 작성해야 할지 적절한 기준과 방법을 몰라 문의드립니다.간략히 예를들어 DBA권고에 따라 외래키 설정은 모두 하지 않는다고 가정해서 아래와 같이 테이블을 생성했을 시에| COMMENT | | COMMENT_IMAGE | | comment_id(PK)| | comment_img_id(PK)| | user_name(PK) | ------- X ------ | comment_img_name | | comment_id | /* DO NOT USE CONSTRAINT foreign key() references */따라서 기존에 아래와 같은 DTO가 있다면,public class Comment { .... private Long id; private String name; private List<CommentImage> commentImages; .... }로 작성되어 있을 경우 아래와 같이 수정중인데... @IdClass(CommentId.class) public class Comment { .... @Id private Long id; @Id private String name; //@? private List<CommentImage> commentImages; .... }기존에는 따로 CommentImage List<>를 조회해서 넣어주면 됐지만cmt = DAO.getComment(id, name); cmt.setCommentImages( DAO.getCommentImageList( cmt.getId() ) ); return cmt; /* getComment SQL SELECT * FROM COMMENT WHERE COMMENT_ID = :id AND USER_NAME = :name; getCommentImageList SQL SELECT * FROM COMMENT_IMAGE WHERE COMMENT_ID = :comment_id; */ JPA의 경우 Domain 클래스에서 Join관련 어노테이션 설정이 없으면 Could not determine recommended JdbcType 오류가 발생합니다. 이 경우 연관관계 생성없이 도메인을 설계하고 사용하는 방법을 알 수 있을까요?

안녕하세요 강사님,강의 정말 잘 듣고 있습니다!40강 관련 질문입니다.git init 명령어를 터미널에서 사용하니 C:/Users/library-app/.git: Permission denied이런 오류가 발생해서 git bash에서 git init을 사용해 보았더니 되더군요.그런데 git add . 입력하면 위와 같은 Permission denied가 또 발생합니다..git status를 입력 하면 아래와 같이 나왔습니다구글링 해 보니 ssh key를 등록하라고 해서 따라서 해 보고 github repository도 삭제했다가 다시 만들어서 실행 해 보았는데도 이렇습니다.무슨 이유에서 인지 .gitignore 파일도 만들어지지 않습니다.제가 구글링으로 해결하려고 이것저것 따라 하다가 더 꼬인 것 같긴 한데....도저히 어디서 부터 잘못된 것인지 모르겠어서 질문드립니다.

spring boot project 에서 hbase 를 사용하려고 하는데요,영한님 강의를 들어보니 data-jpa 를 적용해보고 싶어졌습니다. 구글링해보니 apache-phoenix 구현체(JPA 인터페이스 구현체) 를 활용하면 된다는 이야기도 있긴하지만, 활용 사례가 많지 않아서 정보를 얻기 어려웠는데요~ 혹시 추천해주실 만한 hbase-JPA best practice가 있을까요?

sts3 사용해서 하려는데 강의를 보고 따라하는데 지원이 안되거나 지장이 있을까요 ?

[질문 내용]여기에 질문 내용을 남겨주세요.1. Tasks - other에 compileQuerydsl이 없어서 compileJava를 눌러서 했는데 괜찮은지 ??2.강사님과 다르게 build /generated 이렇게 생성되어도 문제가 없는지?저런식으로 Q파일들이 생성되었는데 import가 안되고 사용이 안되는 이유 알려주시면 감사하겠습니다.

안녕하세요기존에는 CustomUserDetailsService 로 인증처리를 완료했는데 이때 AuthenticationProvider의 anthenticate 메서드 역할은 우리가 만든 loadUserByUsername + 스프링 시큐리티가 기본으로 제공하는 역할을 이용하였고 이번에 새로 추가한 CustomAuthenticationProvider 는AuthenticationProvider의 anthenticate 역할을 커스터마이징 했다고 생각하면 되는걸까요 ?

(예)[질문 내용]강의를 보고 엔티티를 설계하여 프로젝트를 진행하고 있습니다. 강의에서 말씀해주신대로 모든 FetchType을 LAZY로 하여 개발하고 있는데 문득 지연로딩이 실제로 어떤 상황에 필요한지가 궁금해졌습니다.강의에서 말씀해주신대로 연관관계 매핑 데이터를 즉시 가져오지 않고 필요할 때 사용할 수 있도록 할 때 지연로딩을 사용한다는 것은 이해했습니다.실무에서 어떤 상황에 적용되는지 찾아보니, 여러 이미지들을 스크롤하면서 이미지를 실제로 화면에서 보게 될 때 사용하면 효율적이라는 포스팅을 보았습니다.그런데 또 실무에서는 OSIV를 off한다고 보았습니다. OSIV가 off라면 영속성 컨텍스트가 Service, Repository에서만 살아있게 되어 어쨌든 Service 단에서 모두 처리해야 하는데 그렇다면 지연로딩이나 즉시로딩이나 별 차이가 없는 것 아닌가요?? 혹시 제가 잘못 알고 있는 것이 있는지, 어떤 상황에서 지연로딩을 사용하는 것이 좋은지 궁금합니다. 감사합니다:)

(예/아니오)[질문 내용]안녕하세요. 강사님의 강의를 쭉 따라들으며 진행하던 중, 데이터베이스까지 연동을 하여 localhost:8080에 회원 목록이 뜨는 것을 확인했습니다.근데 회원 가입 페이지에서 shkim99라는 이름을 입력하고 엔터를 누른 뒤, localhost:8080 페이지로 갔다가 회원 목록을 눌러보니까 위 사진처럼 인덱스 번호가 2가 아닌 33으로 할당되어 있더라구요... 왜 그런걸까요??코드도 처음부터 끝까지 김영한 강사님과 똑같이 설정했습니다.  그리고 추가적으로 이번 강의의 내용은 실무에서 사용하지 않는 건가요?? 강사님께서 처음에 강의 시작하실 때 "고전 방식이라 우리 선배들은 이렇게 개발했구나~ 하면서 편하게 들으세요." 라고 하셨는데 이번 강의 내용 전체에 대한 말씀이신지 궁금하네요.
