파일 업로드

enctype="multipart/form-data">    form 태그에 꼭 멀티파트를 추가한다!
 
<inputtype="file"class="inp_txt w100p"name="certBusiFile"id="certBusiFile"capture="certBusiFile"accept="image/*"/><br>

이렇게 input으로 값을 가져와서....

java객체로 돌립니다.

            List<HashMap<String, String>> fileList = FileUtil.uploadFile(mutipartRequest);
           
            for(int i=0; i<fileList.size(); i++){
                fileVO.setFileType(fileList.get(i).get("fileType"));
                fileVO.setUserNo(userNo.getUserNo());
                fileVO.setFileNm(fileList.get(i).get("fileNm"));
                fileVO.setFilePath(fileList.get(i).get("filePath"));
                fileVO.setRegUser(userNo.getUserNm());
                fileService.userAttachfile(fileVO);
            }

 

이때ㄴ, 
MultipartHttpServletRequest mutipartRequest, FileVO fileVO ,  의 파라미터를 받아오고....
 

fileutil은...  아래
