안녕하세요. forward(request, response) 할때, process(request, response) 할때 괄호안에 (request, response) 보내 줍니다. 이거에 대한 자세한 이유를 모르겠습니다. 그 메서드 안에 매개변수로 HttpServletRequest request, HttpServletResponse response) 를 받기 위해서 이고, 이, request, response 가 웹 브라우저에서의 요청과 응답을 해주기 위해? 자세히 설명을 못하겠어서 이렇게 질문 올립니다. 

왜 에러가 나오는지 모르겠습니다. Controller에서 Mapping 할 때 그냥 hello로 하면 404가 나오고 /hello 로 하게 되면 500 에러가 나오게 됩니다.   022-05-04 12:15:15.062 ERROR 5008 --- [nio-8080-exec-9] o.a.c.c.C.[.[.[/].[dispatcherServlet]    : Servlet.service()

안녕하세요.  BindingResult를 배우기 전에는 검증 로직을 작성할 때 Service에 작성을 했는데, BindingResult를 도입하고 나서부터는 Controller에 검증 로직이 들어가는데, 그렇다면 검증 로직이 들어가야 하는 부분이 이제는 Controller가 되는건가요?   Controller는 모델과 뷰의 중간 역할을 하고 Service에서 비즈니스 로직을 처리한다고 하면, 검증 로직이 service에 들어가야 할 것 같은데 이 부분이 조금 헷갈리네요..

로그인 세션을 생성할때 해당하는 유저의 객체를 그대로 담아서 생성해도 괜찮은지 궁금합니다.   제가 토이프로젝트를 하면서 로그인의 경우는 사용자가 로그인 요청을 했을때 정보가 일치하다면 해당 객체를 session.addAttribute("user",유저객체); 이런 식으로 세션을 생성했고 로그인이 필요한 로직(글,댓글,예약 등)의 경우는 컨트롤러에서 @sessionAttribute를 사용하여 해당 세션이 유효한지를 체크하고 해당 객체의 PK를 가져와 해당 로직을 수행할 수 있는 유저인지 확인하는 방식을 수행했습니다. 제가 생각하는게 맞는지 모르겠지만 이 경우엔 유저의 개인정보가 고스란히 담겨있어서 안전하지 못하다는 생각이 드는데 사용자는 단순히 세션ID만 알고 있으니 상관이 없는지 아니면 보안상의 문제가 있는지 궁금합니다.   이런 방식보다는 사용자의 PK만 세션으로 생성해서 보내는게 좋을까요? 아니면 더 좋은 방식이 있을까요?

안녕하세요. 스프링 1,2편 듣고 JPA학습중에 Entity를 만들고 2편에서 배운 검증 로직을 대입해 보려고 하는데 막히는 부분이 있어서 질문드립니다. Entity를 강의에서 Setter를 지양하라고 해서 builer를 사용했는데 검증로직파트 보고 검증로직을 적용하려고 하니 View에서 DTO로 값을 받아 Entity.builder()에 넣지 않고 HttpServletRequest로 request.getParameter로 넣어서 따라해 봐도 적용이 안 되네요..  생각해 본 방법은 mvc2편처럼 DTO로 그냥 받아와서 builder에 request가 아닌 DTO값을 받아 넣기..정도인데 따로 JPA, builder 검증하는 힌트가 있을까요?..   강의 보고 따라할 때는 무난하다 했는데 조금만 변형해서 적용하려고 하면 어렵네요..

안녕하세요 강의 잘 듣고 있습니다. 그런데 WAS,서블릿 컨테이너, 서블릿 객체가 헷갈려서 질문드립니다. 강의 중, 서블릿 컨테이너는 톰캣처럼 서블릿을 지원하는 WAS라고 하셨습니다.  더불어, 다른 학생의 질문에 대한 영한님의 답변 중 "request 객체를 만들어서 서블릿에 넘겨주는 것은 서블릿 컨테이너의 역할입니다. response도 마찬가지로 서블릿 컨테이너가 합니다. 그리고 서블릿 컨테이너가 서블릿을 호출해주는 것이지요." 라고 하셨습니다. 그런데 그림에서는 request,response 객체를 생성하고 서블릿 객체를 호출하는 "웹 애플리케이션 서버(WAS)"와 서블릿 객체를 생성하고 관리하는 "서블릿 컨테이너"로 나뉘어져 있네요.  그림에서 "WAS"와 "서블릿 컨테이너"가 사실 같은 큰 서블릿 컨테이너인데 역할에 따라 구분해놓으신건가요??

(예)[질문 내용]안녕하세요. @InitBinder를 넣으면 해당 컨트롤러에서는 어떤 메소드가 실행되도 검증기가 작동한다고 하셨는데 그 중에서 @Validated를 선언한 값만 검증을 수행하나요?   그러면 Controller 윗 줄에 @InitBinder 코드를 적어도 @Validated가 적힌 Item이 없다면 작동을 안하는거로 이해하면 될까요?   감사합니다.

안녕하세요 강사님 맥북 에어 m1 에 intelli j 설치후 따라 가고 있는데 너무 버벅이거나 렉 이 많이 걸립니다 intelli j 메모리 할당도 2기가로 늘려보았는데 작업할때 렉이 심하고 코딩하고있을때 cpu 점유율을 보면 150% 까지 올라가고 그럽니다.. 혹시 해결 방법이 없을까요? 램은 16기가고 구매한지 3개월 됐습니다
