1、Jsp: 上傳文件 至文件夾 默認文件夾 確定 取消 紅色的地方標注：可以上傳文件夾的參數Js：/Dropzone實現上傳文件 var AcceptedFilesLength = 0; var count = -1; var flag = true;Dropzone.options.myDropzone = /添加上傳取消和刪除預覽的鏈接，默認不添加 addRemoveLinks: true, /關閉自動上傳功能，默認會true會自動上傳 /也就是添加一個文件向服務器發送一次請求 autoProcessQueue: false, /用于傳輸文件的名稱 paramName: myFile, /允

2、許上傳多個照片 uploadMultiple: false, /MB maxFilesize: 20, /最大上傳數量 maxFiles: 5, dictFileTooBig: 圖片超出最大20M約束, dictMaxFilesExceeded: 超出最大上傳數量, /限制上傳文件大小的節 parallelUploads: 100, init: function () var submitButton = document.querySelector(#btn-cfmupload) myDropzone = this; / closure /為上傳按鈕添加點擊事件 submitButton.a

3、ddEventListener(click, function () /手動上傳所有文件 myDcessQueue(); ); /當上傳完成后的事件，接受的數據為JSON格式 this.on(complete, function (file) myDropzone.removeFile(file); /alert(this.getAcceptedFiles().length); if(flag) AcceptedFilesLength = this.getUploadingFiles().length; flag = false; if(count = AcceptedF

4、ilesLength) count = -1; flag = true; toast(上傳成功！); refreshLeftLibaryFolder(); Submit(); /alert(this.getUploadingFiles().length= + this.getUploadingFiles().length); /alert(this.getQueuedFiles().length= + this.getQueuedFiles().length); if(this.getRejectedFiles().length != 0) count = -1; Alert(上傳失敗); r

5、eturn; ); this.on(success, function(file,data) var obj = JSON.parse(data); if(obj.result = 1) count+; ); ;Action:/* * 將上傳的文件保存到數據庫 * param model gll * return */ RequestMapping(value = /insertfile,method=RequestMethod.POST) ResponseBody public String insertfile(RequestParam(myFile) CommonsMultipartFi

6、le myFile,HttpServletRequest request,HttpSession session) JSONObject json = new JSONObject(); try int result = 0; String listFolderId = request.getParameter(folderId); String path=ListLibaryController.upload(myFile, request, Const.uploadFolder.listLibary.getValue(), listFolderId); if(null != path) D

7、ecimalFormat df2 = new DecimalFormat(#.0); String size = null; if(Integer.valueOf(path2)0) if(Integer.valueOf(path2)/1024=1024)/如果大于1M size = df2.format(Integer.valueOf(path3)/(1024*1024)+MB; else if(Integer.valueOf(path2)/1024=1024*1024)/如果大于1024MB size = df2.format(Integer.valueOf(path2)/(1024*102

8、4*1024)+G; YtList ytlist=new YtList(); ytlist.setListName(path0); ytlist.setListAddtime(new Date(); ytlist.setListPath(path1); ytlist.setListSize(size); User user = (User)session.getAttribute(Const.SESSION_USER); user = userService.getUserAndRoleById(user.getUserId(); ytlist.setUserId(user.getUserId

9、(); result=ytListService.insertSelective(ytlist); savefolderLink(session,String.valueOf(ytlist.getListId(),Integer.valueOf(listFolderId);/加入文件夾 json.put(result, result); catch (Exception e) logger.error(ListLibaryController.insertfile：異常：+ExceptionUtils.stackTraceInfo2String(e); return json.toString

10、(); /* * List庫上傳功能 * param model gll * return */ public static String upload(CommonsMultipartFile file,HttpServletRequest request,String folderName,RequestParam(folderId) String folderId) String uploadPath = request.getSession().getServletContext().getRealPath(/upload/+/+folderName+/); String arr =

11、new String3; try if(!file.isEmpty() arr0= file.getOriginalFilename(); arr2=String.valueOf(file.getSize(); /定義上傳路徑+時間 String path = uploadPath+DateTypeUtil.getTimeStamp()+; folderId=request.getParameter(folderId); /重命名文件，時間 String rename = DateTypeUtil.getTimeStampMs()+DateTypeUtil.getRandom(4)+arr0.

12、substring(arr0.lastIndexOf(.); File filedir =new File(path);/創建上傳文件 /如果文件夾不存在則創建 . if(!filedir.exists() filedir.mkdirs(); arr1 = path; /拿到輸出流，同時重命名上傳的文件 FileOutputStream os = new FileOutputStream(uploadPath+DateTypeUtil.getTimeStamp()+rename); /拿到上傳文件的輸入流 InputStream in = file.getInputStream(); /以寫字節的方式寫文件 int b = 0; while(b=in.read() != -1) os.write(b); os.flush(); os.close(); in.close(); arr1=/upload
