기존 만들어져 있는 게시판, 수정시 파일첨부 기능 추가하려면..

Question

기존에 만들어져있는 게시판에 글 작성시 파일첨부기능이 있습니다.근데 제가 아직 초보자라 이해가 잘 안갑니다,수정할 때 파일첨부기능이 없는데 추가하고 싶습니다.그래서 코드를 좀 바꿔보았는데 처음보는 에러가 잡히네요,몇일째 고생하고 있습니다 .ㅠ.ㅠ 도와주세요 선배님들 boardServiceImpl.java 에서 public void contentUpdate(CompanyVO cvo, HttpServletRequest request) throws Exception { this.boardDAO.contentUpdate(cvo);//추가내용 수정 진행 여기부터 추가시켰고, List> list= selectFileList(cvo.getCompanyNo()); Map map=fileUtils.updateFileList(list, request); if(map!=null){ map.put("BOARD_IDX", cvo.getCompanyNo()); boardDAO.fileDelete(cvo.getCompanyNo()); boardDAO.insertFile(map); } } BoardController.java 부분 코드입니다.@RequestMapping({"contentUpdate.neon"}) public ModelAndView contentUpdate(HttpServletRequest request, String content, String companyNo) throws Exception{ int companyNO = Integer.parseInt(companyNo);//문자열을 순자형으로 변환 CompanyVO cvo = new CompanyVO();//업체VO 생성 content = content.replaceAll("%", "\%");//아스키코드값을 %로 변환 cvo.setCompanyNo(companyNO); cvo.setContent(content);//업체 VO에 set request.setAttribute("companyNo", Integer.valueOf(companyNO)); boardService.contentUpdate(cvo, request); return new ModelAndView("redirect:companyDetail.neon?companyNo=" + companyNO);//업체 상세페이로 이동}추가된것은 boardService.contentUpdate(cvo)에서 request를 추가시켰습니다. fileUtils 에서 받는값 FileUtils.java에 코드는 public Map updateFileList(List> list, HttpServletRequest request) throws Exception{ MultipartHttpServletRequest multipartHttpServletRequest = (MultipartHttpServletRequest)request; Iterator iterator = multipartHttpServletRequest.getFileNames(); MultipartFile multipartFile = null; String storedFileName =null; String originalFileName=null; String originalFileExtension=null; File file=null; Map map = null; while(iterator.hasNext()){ multipartFile = multipartHttpServletRequest.getFile(iterator.next()); if(!multipartFile.getOriginalFilename().equals("")){//만약 수정할 파일이 있다면 수정 진행 originalFileName = multipartFile.getOriginalFilename();//파일의 원본이름을 할당 originalFileExtension = originalFileName.substring(originalFileName.lastIndexOf("."));//원본파일의 확장자를 할당 storedFileName = CommonUtils.getRandomString() + originalFileExtension;//Commonutils객체의 32자리의 파일명을 랜덤으로 만들어 할당 file = new File(filePath + storedFileName);//업로드 파일명 설정 및 객체 생성 multipartFile.transferTo(file);//수정 파일 업로드 map=new HashMap(); map.put("ORIGINAL_FILE_NAME", originalFileName); map.put("STORED_FILE_NAME", storedFileName); map.put("FILE_SIZE", multipartFile.getSize()); if(list.size()!=0){ //수정전에 업로드된 파일 삭제 storedFileName=(String)list.get(0).get("STORED_FILE_NAME");//수정전 파일 이름 System.out.println("storedFileName : "+storedFileName ); file = new File(filePath + storedFileName);//삭제될 파일 경로 설정 및 객체 생성 file.delete();//파일 삭제 완료 //수정된 파일 업로드 진행 } } } return map; } 이러한데, 왜 수정시에 이런 오류가 뜰까요..?

MultipartHttpServletRequest 강제변환에서 나오는 오류같네요멀티파트리졸버가 없어서 그런걸까요

Mambo · Answer

찾아보니까 1. 멀티파트리졸버가 등록이 안된 경우2. 멀티타입으로 보내지 않고 변환시도하는 경우 (multipart/form-data)3. POST가 아닌경우 인것 같은데요?

jsp 에 파일 서버로 보내실 때 <form name&#61;&#34;formName&#34; method &#61; &#34;POST&#34; enctype&#61;&#34;multipart/form-data&#34;> 설정이 안되있는거 아닐까요?

String companyNo 이 Null이 들어오나보네요 int는 원시타입이기 때문에 Null은 변환이 안되는 것으로 알고있어요

안두로 · Answer

companyNO 값을 못 받아오시는거 같은데요 null 을 회피하시던지jsp 에서 companyNO 값이랑 controller에서 companyNO 값이 null이 아니도록 만드셔야 될거 같습니다.

GB · Answer

왜그런지 잘 모르겠네요,왜 cvo에서 companyNO의 자료형은 int인데 컨트롤러에선 String으로 쓸수밖에없는건지..이런 기본적인문제를 모르는 제가 참 답답하고 한심하네요.. &#64;RequestMapping({&#34;contentUpdate.neon&#34;}) public ModelAndView contentUpdate(HttpServletRequest request, String content, String companyNo) throws Exception{ int companyNO &#61; Integer.parseInt(companyNo);//문자열을 순자형으로 변환 CompanyVO cvo &#61; new CompanyVO();//업체VO 생성 content &#61; content.replaceAll(&#34;%&#34;, &#34;\%&#34;);//아스키코드값을 %로 변환 cvo.setCompanyNo(companyNO); cvo.setContent(content);//업체 VO에 set request.setAttribute(&#34;companyNo&#34;, Integer.valueOf(companyNO)); boardService.contentUpdate(cvo, request);//업체 수정 서비스 실행}

contentUpdate(HttpServletRequest request, String content, String companyNo)-> contentUpdate(HttpServletRequest request, String content, int companyNo) 이렇게 받아올 수 있어요

아 그런거라면 구지 int로 바꾸실 필요는 없을 것 같고companNo를 Integer.parsInt하기전에 companyNo가 &#34;&#34;이거나 Null일경우를 처리해주시는게 나을 것 같네요

GB · Answer

companyNo &#61; &#34;&#34;; int companyNO &#61; 0; if (!&#34;&#34;.equals(companyNo)) { companyNO &#61; Integer.parseInt(companyNo); } 이런식으로요??

Mambo · Answer

....위에 두개는 왜적으셧는지는 모르겟고..보통 변수를 왼쪽에 두지않나요.. if (!(companyNo &#61;&#61; null || companyNo.equals(&#34;&#34;))) { companyNO &#61; Integer.parseInt(companyNo); }

GB · Answer

String A; if ( A.equals(&#34;&#34;) ) { // 처리} if ( A.equals(null) ) { // 처리} 흠..

Mambo · Answer

.equals같은 함수는 그 변수 자체가 null이면 NullPointerException이 발생해요그래서 변수 &#61;&#61; null 일 경우를 먼저 확인하는게 좋아요 제가 취준생이지만 그렇게 배웠거든요
