2.頁面html
<div id="images_" class="file_img"> <input type="file" class="form-control btn-3.導入js <script src="${pageContext.request.contextPath}/resource/js/jquery/jquery.js" type="text/javascript"></script><script src="${pageContext.request.contextPath}/resource/js/layer/layer.js" type="text/Javascript"></script><script src="${pageContext.request.contextPath}/resource/js/upload/Ajaxfileupload.js" type="text/javascript"></script><script src="${pageContext.request.contextPath}/resource/js/upload/uploadFile.js" type="text/javascript"></script>function saveFile_cover(imgid,target_img) { $.ajaxFileUpload({ url : '../upload/saveUploadFile.html', secureuri : false, fileElementId : [ imgid ], dataType : 'text', success : function(data) { var url = data.substring(data.indexOf("[")+1,data.indexOf("]")); $("."+target_img).css({"background":"url('../../"+url+"') no-repeat center","background-size":"500px"}); $("#cover").val(url); }, error : function(data) { alert("error"); } });}4.后臺java
@RequestMapping("/saveUploadFile") @ResponseBody public void saveUploadFile(HttpServletResponse response , HttpServletRequest request) throws Exception{ String imagePath = null; List<String> fileList = new ArrayList<String>(); CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver(request.getsession().getServletContext()); if (multipartResolver.isMultipart(request)) { MultipartHttpServletRequest multiRequest = (MultipartHttpServletRequest) request; Iterator<String> iter = multiRequest.getFileNames(); while (iter.hasNext()) { MultipartFile file = multiRequest.getFile(iter.next()); if (!file.isEmpty()) { String originalFileName = file.getOriginalFilename(); //原文件名 //前綴 String prefixString = UUID.randomUUID().toString().replace("-","")+UUID.randomUUID().toString().replace("-","").substring(2,7); //后綴 String suffixString = originalFileName .substring(originalFileName.lastIndexOf(".") + 1); //判斷后綴類型 返回 下載路徑 String suffixType = FileUtil.getTypeBySuffixName(suffixString); String[] suffixType_ = suffixType.split(","); String filetype = suffixType_[0]; String suffixTypeStr = suffixType_[1]; String fileName = prefixString + StringUtil.getCharAndNumr(6,"03") + "." + suffixString; String uploadUrl = request.getSession().getServletContext().getRealPath("/") + "/" + suffixTypeStr; File dir = new File(uploadUrl); if (!dir.exists()) { dir.mkdirs(); } File targetFile = new File(uploadUrl + fileName); imagePath = suffixTypeStr + fileName; fileList.add(imagePath); if (!targetFile.exists()) { try { targetFile.createNewFile(); } catch (IOException e) { e.printStackTrace(); } try { file.transferTo(targetFile); /*YhFile yhFile = new YhFile(); yhFile.setCreatetime(new Date()); yhFile.setDelflg(Global.DELFLG_00); yhFile.setFilename(originalFileName); //原文件名稱 yhFile.setFileplace(imagePath); //存儲路徑 Long l = FileUtil.getFileSizes(targetFile); yhFile.setFilesize(FileUtil.FormetFileSize(l)); //文件大小 yhFile.setFiletype(filetype); yhFile.setParentid(parentid); yhFile.setStatus(Global.STATUS_USABLE); yhFile.setSuffixname(suffixString); fileService.addFile(yhFile); int fileId = yhFile.getId(); int userId = 1; UserFile userFile = new UserFile(); userFile.setFileid(fileId); userFile.setUserid(userId); userFileService.addUserFile(userFile);*/ } catch (IllegalStateException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } } request.setCharacterEncoding("UTF-8"); response.setContentType("text/html; charset=UTF-8"); response.getWriter().print(fileList); } } }5、添加新一個html
