안녕하세요. 친절하고 좋은 설명 덕택에 저번 기본편부터 이번 실전편까지 강의를 재미있게 듣고 있습니다. 제목 그대로, @Component가 아니라 @Repository 애너테이션을 붙이는 편이 더 낫지 않나 해서 질문 드립니다:@Repository 애너테이션을 붙임으로써, 스프링에서 Data Access 과정에서 발생하는 예외들을 스프링 예외들로 번역해주는 기능을 제공한다는 점에서해당 빈이 @Repository 임을 명시해주는 편이 해당 빈이 어떤 역할을 수행하는가에 대한 설명이 되기 때문에그렇다고 생각했습니다. 저번 시간의 경우 QueryDslRepo를 interface로 만들고, 해당 인터페이스를 이용해 기존 Repo와 연결하는 방식을 사용했었는데, 그 경우에는 @Repository 애너테이션이 붙는 것으로 처리된다(최종적으로는 `@JpaRepository`를 extends한 것이 빈으로 등록되니까요)고 알고 있습니다. QueryDSL 2편과 마지막 편에서 QueryDslRepository에 @Component를 붙이신 것이 어떤 이유인지 궁금합니다. 감사합니다.

영상 강의랑 똑같이 했는데 (')(' te'b'st) 전부 삽입해보았는데 이런 식으로 떠요Posts does not exist. 뜨네요참고로 test 도 작성 했습니다          -______________________________________________해결안료! 매직쿼터 지피시 on 을 off로 햇씁니당 ㅎㅎ 제가 환경구성 강의하나 빼먹었네요 ㅜㅜㅋㅋㅋㅋ

그냥 변수명을 int true = 1, false = 0;이라고 지어서 printf("True is %d\n",true); printf("False is %d\n", false);이렇게 출력하는거랑 똑같지 않나요?왜 사람들이 bool타입을 만들어서 사용하는건가요?

본 강의에서 사용된 fabs() 말인데요.fabs()를 사용하지 않고그냥 while ((guess - PI) > 0.01)이라고 코드를 짜면왜 제대로 돌아가지 않는건가요?guess도 PI도 다 double로 선언되어 있으니까 두 변수를 뺀 값도 double 타입을 가져서 소수점 자리수가 상세하게 저장되지 않나요? 그래서 (guess - PI) > 0.001이 제대로 계산될 줄 알았는데, fabs를 사용하지 않으면 결과값이 제대로 출력되지 않네요...?

안녕하세요 선생님, 개인 포트폴리오 홈페이지를 포함해서 반응형 웹 사이트 작업물들에 대한 HTML, CSS 유효성 검사도 하나씩 다 해야 하나요?초반에 몇 번 검사를 해서 img태그의 alt속성 오류 및 h태그 중복 등 오류가 많이 떠서 일일이 고쳤었지만, 양이 방대해서 중단했습니다. 개인 홈페이지 제작 중 웹 접근성, 웹 표준을 지킨다는 문장을 넣으려다 보니 괜히 마음에 조금 거슬리네요..

안녕하세요. 강의 교재건으로 거듭 문의드려 죄송합니다만 공유 일정 한 번만 더 확인을 부탁드리겠습니다. 감사합니다.  

- 학습 관련 질문을 남겨주세요. 상세히 작성하면 더 좋아요! - 먼저 유사한 질문이 있었는지 검색해보세요. - 서로 예의를 지키며 존중하는 문화를 만들어가요. - 잠깐! 인프런 서비스 운영 관련 문의는 1:1 문의하기를 이용해주세요.빨간 줄이 그어진 저 구문에서 오류가 납니다.. 404값으로 돌려주지 않을 때는 정상 작동하였는데저 구문에서 오류가 발생합니다 무엇이 문제일까요 .. 막히는 부분은 구글링으로 거의 대다수 해결이 됐는데,, 이번에는 검색해봐도 알 수가 없어 질문드립니다 ㅜㅜ
