Q1. 처음 new-form 에 들어오게 되면 FrontControllerServleV3에서는 Http 메세지 바디에 있는 파라미터들을 만들어서 paramMap 으로 만들고, 이것들 MemberFormControllerV3에 넘겨줄거고 여기서 "new-form"이라는 String을 가진 ModelView를 리턴받는 mv가 생기고,   이 mv.getViewName 해서 나오는 viewName은 논리이름이기 때문에 viewResolver로 상대 이름으로 바꿔주고, 이것은 MyView에 있는 render로 보내서 new-form 화면이 뜨게 되는 것인가요 ??   Q2. 그 후 MEmberListControllerV3, MemberSaveControllerV3 에서 ModelView에 있는 HashMap으로 구현 된 model에 members와 member를 넣어주는데 넣는 이유가 궁금합니다. 실제로는 memberRepository 에 저장하고, findAll를 하기때문에 사실상 MemberRepository와 ModelView에 있는 Model은 항상 같은 것 아닌가요? 맞다면 왜 굳이 2가지의 객체를 만들어서 사용하는지가 궁금합니다.

안녕하세요. @GetMapping("/hello") public void hello(Model model){ model.addAttribute("data", "hello!"); }   웹 브라우저에서 hello 경로로 접근할 때 컨트롤러에서 리턴 값으로 문자를 반환하면 뷰 리졸버가 화면을 찾아서 처리한다고 하셨는데 return 반환값이 없는 void로 해도 접근이 가능해서요. hello 경로에 접근하면 스프링 내부에서 resources -> static -> templates 순서대로 hello.html이 있는지 확인하는게 아닌가 싶어서 질문드립니다!

제목과 같이 MessageSource 변수명을 ms로 바꾸면 빨간줄이 나오는데 어떻게 해결해야 하나요? 강의 소스를 열어도 똑같이 빨간줄이 나옵니다.ㅜㅠ   @Aotuwired위에 @Qualifier("messageSource") 를 하면 되기는 하는데 왜 저는 @Qualifier을 해야 되는 걸까요?    

@Slf4jpublic class UserHandlerExceptionResolver implements HandlerExceptionResolver { private final ObjectMapper objectMapper = new ObjectMapper(); @Override public ModelAndView resolveException(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) { try { if (ex instanceof UserException) { log.info("UserException resolver to 400"); String acceptHeader = request.getHeader("accept"); response.setStatus(HttpServletResponse.SC_BAD_REQUEST); if ("application/json".equals(acceptHeader)) { Map<String, Object> errorResult = new HashMap<>(); errorResult.put("ex", ex.getClass()); errorResult.put("message", ex.getMessage()); String result = objectMapper.writeValueAsString(errorResult); response.setContentType("application/json"); response.setCharacterEncoding("utf-8"); response.getWriter().write(result); return new ModelAndView(); } else { //TEXT/HTML return new ModelAndView("error/500"); } } } catch (IOException e) { log.error("resolver ex", e); } return null; }} mvc 1편에서  ContentType : application/json은  원래 utf-8을 쓰게 되어 있어서  charset=utf-8 즉,  response.setCharacterEncoding("utf-8"); 는 의미 없는 파라미터가 추가되는 것이라고 하셨는데   여기서 response.setCharacterEncoding("utf-8"); 코드를  쓴 다른 이유가 있는 건가요 ?

강의내용중 31:24초 부분에 해당하는 질문입니다. 다른 사이트 이미지를  마우스 우클릭후, '새탭으로 이미지 열기'로 보면 제대로 이미지가 새탭으로 출력이되서 보이는데,   이 프로젝트 코드는 새 탭으로 이미지 열기를 사용하는데 31:20초  /items/1  경로의 이미지처럼 나오지않고 문자형태로 출력이되는지 궁금합니다.   또한 이처럼 31:24초처럼  이미지가 문자형태로 출력되지 않고  다른사이트(구글,네이버)처럼 새탭으로 이미지를 열어도 정상적으로 이미지가 출력되게 하기위해선 어떻게 해야하나요?

  저는 영한님이랑 다르게 user-agent 까지만 나오고 form-data 부분이 안나옵니다. 어떻게 확인할 수 있을까요?

세션 과정을 위의 표와 같이 이해했습니다. 영한님께선 세션Id가 털려도 여기에는 중요한 정보가 없다.   즉 털려도 상관없다라는 식으로 말씀하셨는데, 위 표와 같이 제가 이해한게 맞다면 결국 해커가 세션 키만 안다면 해킹을 할 수 있는게 아닌가?라고 생각이 들었습니다. 맞는 방식인지는 모르겠으나 테스트를 해봤습니다 두 개의 창을 띄워 각 다른 아이디로 로그인 했습니다. 표 처럼 B의 세션키를 A에 적용했을 때 B로 바뀌는 모습을 확인할 수 있었습니다. 근데 이게 될 때도 있고 안 될 때도 있습니다.. 정확한 이유를 모르겠네요   물론 해킹을 100% 막을 순 없겠지만 생각보다 쉽게 털리는 것이 아닌지 의문점이 생겼는데, 제가 무엇을 잘못 알고있는걸까요?  

이미지는 엑박으로 표기.->새탭에서 이미지열기시, 나오는경로-http://localhost:8080/images/C:/Users/계정/springfile/images/c3a2eedd-4364-4f3f-a275-a800512e4949.png 파일다운로드 클릭시 경로와 에러페이지,http://localhost:8080/attach/C:/Users/계정/springfile/uploadfiles/9aa381e7-6b8d-412a-bf86-28caf5b29010.pdf 으로 됩니다. ---- save시 컴퓨터 경로에 사진, 파일이 저장이되고db에도 잘 저장됩니다.. 코드 <img th:each="imageFile : ${board.attachFiles}" th:if="${imageFile.attachType.toString().equals('IMAGE')}" th:src="|/images/${imageFile.storeFileName}|" width="300" height="300" style="margin-right: 5px"/> <a th:each="uploadFile : ${board.attachFiles}" th:if="${uploadFile.attachType.toString().equals('FILE')}" th:href="@{/attach/{filename}(filename=${uploadFile.storeFileName}, originName=${uploadFile.uploadFileName})}" th:text="${uploadFile.uploadFileName}" style="margin-right: 5px"/><br/> @ResponseBody@GetMapping("/images/{filename}")public Resource processImg(@PathVariable String filename) throws MalformedURLException { return new UrlResource("file:" + fileStore.getFullPath(filename, AttachType.IMAGE));@GetMapping("/attach/{filename}")public ResponseEntity<Resource> processAttaches(@PathVariable String filename, @RequestParam String originName) throws MalformedURLException { UrlResource resource = new UrlResource("file:" + fileStore.getFullPath(filename, AttachType.FILE)); String encodedUploadFileName = UriUtils.encode(originName, StandardCharsets.UTF_8); String contentDisposition = "attachment; filename=\"" + encodedUploadFileName + "\""; return ResponseEntity.ok() .header(HttpHeaders.CONTENT_DISPOSITION, contentDisposition) .body(resource);}

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.

설명 : request.getSession()을 하면 request 정보에서 얻어온 UUID값으로 이뤄진 쿠키의 value 값을 보고 Session들을 모아둔 Session저장소에서 동일한 sessionId(=UUID) 값이 있는지 찾는다. // Session저장소에서  sessionId는  key값으로 쓰인다. 동일한 sessionId가 있으면 해당 Session을 가져오고, sessionId가 없으면 해당 Session을 새로 만들어 반환한다. session.setAttribute(SessionConst.LOGIN_MEMBER, loginMember)를 하면 request.getSession으로 가져온 특정 Session 내에 key(=SESSIONCONST.LOGIN_MEMbER)와 value(=loginMember)를 저장시켜 나중에, sessionId를 통해 특정 Session을 가져올 때 가져온 Session 내에서 key(loginMember)를 가지고 loginMember 값을 가져올 수 있다. -----------------------------------설명 끝--------------------------------------------------- HttpSession코드를 보면서 갑자기 이러저러한 의문점이 들어서 커뮤니티 질문과 답변글 보면서 위와 같이 정리했는데    맞게 이해한 건지 확인이 필요합니다..

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?
