@layer base { #__next { display: contents; } }#__next를 레이어 두어 스타일링 명시도를 낮춘 것에 대한 이유가 궁금합니다.혹시 next.js 내부에서 (프레임워크 내부에서) id : __next 를 스타일링하면 내가 작성한 코드보다 우선시 되도록 하기 위함인가요??

ItemService에서는 ItemRepository의 기능을 위임받아 저장 및 검색 기능을 구현했는데OrderService에서는 검색기능을 구현하지 않았더라구요. ItemService에서 위임 받는 것 처럼 하면 간단할 것 같은데 굳이 만들지 않고 OrderRepository의 findOne기능을 사용하는 이유가 따로 있는 것일까요?

안녕하세요 선생님,yarn을 사용중이었는데, Ubuntu에서 npm이 아니라 yarn을 설치하면 되겠죠?

https://drive.google.com/file/d/1tCpv16Aj0Q-U95EPxE43t-Y-8L1lidhy/view?usp=share_link Letter과 Member을 ManyToOne로 매핑하려고 했는데 데이터베이스를 보니 자꾸 null이 떠서 올립니다.. 파일은 에러가 생기기 전 잘 실행이 되는 파일입니다.

 tobyspring.config.MyAutoConfiguration.imports 파일 생성 후 포맷이 변경되지 않는 것 같습니다.그냥 파일이 된 것 같습니다. imports 포맷의 파일로 생성이 되지 않는 것 같아서 따로 다운받거나 설정해야 할 것이 있을까요?

안녕하십니까.깃발을 클릭해서 미션을 수행하라 하셨는데, 깃발이 보이지 않습니다..

//API 호출 Response res = await Dio().get( "https://www.googleapis.com/books/v1/volumes?q=$q&startIndex=0&maxResults=40"); //정상적으로 작성... 그런데 값이 리턴이 안된다 . 에러 ..  [ Book Stor 실습 ] 부분Exception has occurred. DioError (DioError [unknown]: null Error: SocketException: Failed host lookup: 'www.googleapis.com' (OS Error: No address associated with hostname, errno = 7)) 작성하고 나서 .. 사이트 접속하니 . 오류 404 (찾을 수 없음)!! 1 (www.googleapis.com)상태입니다 ... 안드로이드 매니페스트등 공부할 부분많았는데 .. 너무 아쉽습니다.

질문 내용]여기에 질문 내용을 남겨주세요. 일단 두 사진 보시면, 예외 처리를 해주면 예외 처리가 try 내부 코드가 예외를 안던지니까 catch 빼라고 하고,예외 처리를 안해주면, IOException이 예외처리가 안됐다고 하네요..뭐가 문제죠..?람다를 사용했다고 해서 안될리가 없어보이는데 ㅠㅠ 추가로 out.write();가 Writer 추상 클래스의 write(); 메서드고 checked예외를 던지던데, try-catch로 안잡아줘도 되는 이유가 뭔가요??

저같은경우 opt/java/openjdk였습니다

[질문 전 답변]1. 강의 내용과 관련된 질문인가요? [예 ]2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? [예 ]3. 질문 잘하기 법을 읽어보셨나요? [예 ](https://www.inflearn.com/blogs/1719)4. 잠깐! 인프런 서비스 운영 관련 문의는 1:1 문의하기를 이용해주세요.[질문 하기]CentOS 사이트가 변경 되면서 다운로드 하는 방법이 변경 된 듯 합니다.강의에서 사용하는 CentOS 버전을 다운로드 하는 링크나 파일을 있으면 공유 부탁드립니다. 

강의자료/완성사이트 접속 모두 안되네요. 서비스 안하시는건가요?

woohakim@naver.com 강의자료 부탁드립니다! 감사합니다.

안녕하세요 선생님 bat 스크립트 파일을 unix 환경에서 실행시킬 수 있도록 sh 파일로 바꾸고 싶습니다.단순히 파일 이름만 bat에서 sh로 바꿔도 될까요?변환하려면 어떻게 해야할까요?좋은 하루 보내세요

안녕하세요!선생님 강의를 재밌고 유익하게 수강하고 있는 학생입니다.스프링 MVC 2편 - 백엔드 웹 개발 활용 기술 강의의 bean validation - HTTP 메시지 컨버터 부분을 수강하던 중 강의 내용과 제 결과 케이스의 다른 부분이 있어 다른 결과가 나오게 된 원인이 궁금하여 질문 드립니다!강의와 결과가 달랐던 부분은 postman으로 실패 요청을 send했을 때의 응답 결과 입니다.강의의 결과입니다.{ "timestamp": "2021-04-20T00:00:00.000+00:00", "status": 400, "error": "Bad Request", "message": "", "path": "/validation/api/items/add" }제가 실행한 결과입니다.{ "timestamp": "2021-04-20T00:00:00.000+00:00", "status": 400, "error": "Bad Request", "path": "/validation/api/items/add" }보이는 바와 같이, 제가 실행한 결과에서는 message에 대한 json 객체가 존재하지 않습니다. 혹시 스프링 부트의 버전과 관련된 부분에 있어서 차이가 있을까요?현재 사용 중인 스프링 부트 버전은 2.7.11 버전입니다.

아래처럼 if문에 return 없이 코드를 짜도 괜찮을까요??function solution(n) { let answer = ""; function DFS(n) { if (n === 1) answer += 1; else { DFS(Math.floor(n / 2)); answer += n % 2; } } DFS(n); return answer; }

안녕하세요.강의를 보면 강의자님의 VSCODE 에서는 백틱 내에서도변수, 함수 등이 글자 색상이 각각 다르게 표현됩니다.그런데 제 VSCODE에서는 백틱 내에서는 모두주황색으로 나옵니다.이 부분은 어떻게 옵션을 바꿔야하나요?구글링해도 못 찾겠네요. 

안녕하세요!headless를 이용하면 안되는 사이트도 있는거 같아서.그냥 크롬창을 띄워놓고 작업을 하는데요.탭을 2개 열어 놓고 작업을 시켰습니다.근데 탭을 변경하면 최소화된 크롬창이 자꾸 활성화 되면서 모니터 앞으로 튀어나오는데요..탭 변경시driver.switch_to.window(driver.window_handles[0])이 코드를 사용하는데요.0에서 작업하다가 1로 넘기면,넘길 때 마다 크롬창이 앞으로 팍 튀어나옵니다!해결 방법이 있을까요?headless를 사용하지 않고, 크롬창이 열리는 대신, 그냥 최소화 해놓고 작업을 하고 싶습니다!
