토비님이랑 같은 의존성 주입 받았는데 전 HikariDataSource라는 class가 존재하지 않습니다. 제가 잘못한게 있을까요

사용자가 login페이지에 처음 접근한다고 가정해요그럼 그 사용자는 loginId나 비번을 입력하지 않은채로 페이지를 보여달라고 요청하는거겟죠그러면 어차피 loginId나 비밀번호는 null일거예요근데 왜 parameter로 loginForm을 받고있는건가요?제가 그 이유를 추측해봤어요 제 생각이 맞는지 봐주세요!modelAttribute를 사용해서 model에 만든 객체가 등록됨form이 null이면 form.loginId로접근할때 null참조 에러가 발생해서 서버죽음.그상황을 막기위해서 model에 객체생성해서 넘겨줌

 혹시 과제 풀이를 볼수 있는곳이 있을까요?

로그인 할 때 Member 객체의 password 값에 ,(쉼표) 가 포함되어지는데 왜그런지 모르겠습니다. ㅠ  memPassword12 는 테스트 용으로 만들어 봤습니다. debug 를 찍어서 데이터를 확인 했는데 memPassword 부분에서 ,( 쉼표)가 포함됩니다. 테스트로 만든 memPassword12 에는 쉼표가 포함되지있지 않습니다. 컨트롤러에서 debug 를 찍어서 확인 했는데 넘어 올 때 왜 쉼표가 붙는지 모르겠습니다 ㅠ Member 클래스 입니다. UI 에서도 똑같이 1234를 적고 로그인 버튼을 클릭했는데 Member 의 password 에는 쉼표가 붙고String 으로 받은 password 는 정상적으로 나오는데 무슨 차이가 있는지 모르겠네요 ㅠㅠ

요금제 사려는데 구매중지되어 있다고 하는건 개인문제인가요

안녕하세요 단위심화 강의 중 두 번째 실습 과정 중, 두 번째 줄에 사진이 3개만 들어가는데 왜 그런건지요..?? flex-wrap: wrap; 까지 적용시켰는데 영상과는 다르게 되네요..  

맛비님 안녕하세요, 10장 counter 강의를 듣고 질문 사항이 생겨 글 남기게 되었습니다.counter를 설계할때 sw 처럼 cnt = cnt + 1; 설계하면 안된다고 Combinational Logic의 정의와 함께 설명해주셨습니다.이때 Combinational Logic은 입력과 동시에 출력이 결정되기 때문에 저장공간 없이 같은 변수 cnt를 사용하면 안된다고 이해하면 될까요 ? 좋은 하루 되세요.

제가 겪었던 문제는node를 생각없이 치고 terminal에서 위와 같은 오류값을 얻었는데요. 원인은 아래와 같았습니다.Terminal 옆에 "2: node"로 되어있는 부분이 Terminla에 node를 실행시키면 나오던데 node 환경에서node test.js 가 안 먹는 모양입니다.node가 아닌 bash나 zsh 콘솔에서 실행해야 코드가 정상적으로 작동되는 것 같아요. 

회원가입을 하려고 할때 이런 오류가 뜨는대요 완성본 파일에서 ChatPage의 Manipanel을 가져오면 이런 오류가 사라집니다.오류내용을 번역하면 소스를 통해 호스팅에 배포되지 않은 경우 옵션을 제공해야 합니다. (app/no-timeout).이게 뭘 의미하는지 모르겠습니다답변 부탁드립니다!  

관련 에러를 찾아보니 ip주소를 0000이나 내 컴퓨터 ip를 입력해봐서 해결한 경우를 보았으나 제 경우는 해결되지 않습니다. 어떻게 해결할 수 있을까요? 아래 오류 코드입니다.  MongoServerError: bad auth : authentication failed at Connection.onMessage (/Users/shinheejin/Documents/boiler-plate/node_modules/mongodb/lib/cmap/connection.js:227:30) at MessageStream.<anonymous> (/Users/shinheejin/Documents/boiler-plate/node_modules/mongodb/lib/cmap/connection.js:60:60) at MessageStream.emit (node:events:513:28) at processIncomingData (/Users/shinheejin/Documents/boiler-plate/node_modules/mongodb/lib/cmap/message_stream.js:125:16) at MessageStream._write (/Users/shinheejin/Documents/boiler-plate/node_modules/mongodb/lib/cmap/message_stream.js:33:9) at writeOrBuffer (node:internal/streams/writable:392:12) at _write (node:internal/streams/writable:333:10) at Writable.write (node:internal/streams/writable:337:10) at TLSSocket.ondata (node:internal/streams/readable:766:22) at TLSSocket.emit (node:events:513:28) { ok: 0, code: 8000, codeName: 'AtlasError', connectionGeneration: 0, [Symbol(errorLabels)]: Set(2) { 'HandshakeError', 'ResetPool' }} 

MYSQL 트랜잭션이 열리고 UPDATE 쿼리가 나가고커밋이나 롤백이 되기전까지는 LOCK이라고 설명주셨는대요.여기서 이 트랜잭션안의 변경시 발생하는 락이랑조회시 사용하는 select for update 락이랑 같은 종류의 락인가요?햇갈리는 부분이 있어서요.강의서 설명된 MYSQL 락이랑 관적락과 비관적락이랑 전혀 다른 개념인가해서요. 본 질문의 의도는 그래서 어떤게 MYSQL 자체의 락이고 그 명칭은 뭐라 불리는건지 그리고 그것이 낙관락 비관락과 연관된건지? 아님 다른건지

@Query(native = true)로 하게되면은 JdbcTemplate과 비슷한 효과를 가지면서 정적 쿼리를 수행할수있잖아요그런대 jdbTemplate을 별도로 사용하는건 어떤 이유 인지 궁금합니다.@Query를 이용한 네이티브 쿼리에서 할수 없는 특별한 기능이 있다면 그게 무엇 때문인지 궁금하네요.

아무리봐도 강의랑 똑같이 쳤다고 생각했는데 하트가 안바뀌어서 질문올릴까 말까 고민하다가 오타발견해서 해결하였네요 ㅠㅠ setPostList(prevList => { return prevList.map(currentPost => currentPost === post ? { ...currentPost, is_Like: isLike } : currentPost ); }); is_like is_Like isLike 너무 똑같은 변수명이고 post , postlist 에서 같이 쓰다보니깐 헷갈리는데 혹시 같은문제로 안되시는분 있을까해서 올립니다

스프링 트랜잭션매니저에서 지원하는 전파(propagation)는스프링에서 지원하는 자체 기능인거죠?아무리봐도 MYSQL에서 지원하는 기능으로보이진 않아서요맞는지 궁금합니다

 안녕하세요. 수강생입니다. 다름이 아니라 메뉴 등록시 조회가 되고 어쩔 땐 등록페이지로 갑니다. http://localhost:8080/menu?start_date=&end_date=&name=&kind=ALL 원인을 못찾겠어서 문의드립니다. 감사합니다.
