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?

프로그래밍을 공부한지 얼마 안된 학생입니다. 자바스크립트로 무언가를 구현하는 강의를 듣는게 거의 처음인데요,   강의를 적어도 2회는 볼 생각인데, 처음 볼때 강의하시는내용을 함꼐 따라 코딩하면서 공부해야할지 아니면 처음에는 강의에 집중하고 2회차 볼때 따라서 만들며 해야할지 잘 모르겠습니다.   더듬더듬 따라서 강의를 보는 중인데, 똑같이 타이핑하는거에 너무 집착하는거같기도해서요.. 어느게 좋을지 추천 부탁드립니다.

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??

item과 itemForm 분리 이유는 아래 링크를 통해 이해하였습니다. https://www.inflearn.com/questions/246930   수업 시간에 이미지 수정에 대해서는 다루지 않았지만 혼자 해보고 싶어서 하는중입니다.   [이해하고 있는 플로우] 1. itemForm에 담겨있던 이미지를 통으로 저장하지 않고 item에 이름만 저장한다. 2. item 상세페이지로 리다이렉션을 한다. 3. item 상세페이지에서는 itemId를 사용하여 저장되어 있는 item을 model에 담아 넘겨주고 화면을 구성한다.   [질문] 이미지를 수정하려면 UploadFile이 아닌 MultipartFile이 필요하다고 생각합니다. 이미지를 수정할 때는 보통 MultipartFile을 따로 저장하는 작업을 추가하는지 궁금합니다.    

<div th:replace="/fragments/header.html :: fragment-header"></div> 이렇게 헤더, nav, 사이드바를 대체하고 있는데요  도메인/edit 에서는 잘 적용되던 html,css 들이  도메인/edit/1 등등 이렇게 구체적으로 들어가면 100% 똑같은 뷰를 반환해도 절대 적용이 안됩니다.. 5시간째 이유를 못찾고 있습니다 @GetMapping("/project/edit/1")public String Edit1(Model model){ //1번 return "editProject";}@GetMapping("/edit")public String Edit2(Model model){ //2번 return "editProject"; } 1번과 2번의 뷰가 각각  1. 2. 이렇게 나타납니다. 똑같은 뷰를 써도 저렇게 나오는 이유가 무엇인가요? Edit1(), Edit2()는 필수부분만 캡처한겁니다  똑같은 뷰를 반환하는데도 url에 따라 css가 다르게 적용 되는 이유가 무엇일까요??  혼자서해보려했는데 너무 안되서 질문드립니다. --헤더 내부-- <link rel="stylesheet" href="bootstrap/css/bootstrap.min.css"> http://localhost:8080/project/edit/bootstrap/css/bootstrap.min.css   잘못된 css 경로  -< 이렇게 가네요  http://localhost:8080/bootstrap/css/bootstrap.min.css   가야하는 css 경로 빨간색 경로가 안붙게 하려면  어떻게 하나요?

[질문 템플릿]1. 강의 내용과 관련된 질문인가요? (예)2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? (예)3. 질문 잘하기 메뉴얼을 읽어보셨나요? (예)[질문 내용] 영한님 안녕하세요. 먼저 항상 이렇게 훌륭한 강의 만들어주셔서 정말 감사드립니다.   강의 중에 BindingResult 인터페이스의 구현체로 BeanPropertyBindingResult 클래스가 들어온다고 말씀해주셨는데, BindingResult 인터페이스의 구현체 종류가 많이 있는 상태에서 어떤 구현체가 들어올지 어떻게 알 수 있는지 궁금합니다.   + 여러개의 구현체를 사용해야하는 상황을 위해서 많은 클래스들을 전부 미리 빈으로 등록을 하는 것인지, 아니면 default 구현체를 autoconfiguration으로 설정해두고, 필요에 따라 bean을 추가적으로 (condition..?) 생성해내는지도 궁금합니다   + spring.factories 파일을 따라가서 springboot가 지원해주는 autoconfiguration을 따라가면서 bean으로 등록하는 위치를 찾아보는 게 맞는 방법인가요? (타고타고 가다보니 너무 파일이 방대해져서 아직 찾지못했습니다 ㅠㅠ) 

  웹페이지 만들기 부분을 수강하면서 상품 도메인 개발(Item - 상품객체) 부분에서 도메인이라는것이 다른 개념들과 헷갈립니다   도메인, 파라미터, DTO 이 3가지 개념이 지금 혼동되는데 설명해주실수 있을까요? 도메인을 파라미터 아니면 dto와 같은 개념으로 봐도 될까요?
