前臺頁面：引入js和css

2：腳本內容： css

以下參數你還沒搞懂的話，請查閱官方文檔，地址：http://www.uploadify.com/documentation/ html

2：<body>內容： jquery

<body >
<input id="file_upload" type="file" name="file"/>
<a href="javascript:$('#file_upload').uploadify('upload', '*')">上傳文件</a> | <a href="javascript:$('#file_upload').uploadify('stop')">中止上傳!</a>
</body> app

3：後臺controller： dom

@RequestMapping(value = "/shop/upload",method=RequestMethod.POST)
   @ResponseBody
   public Object uploadHandlerForUploadify(String picHref,HttpServletRequest request)
           throws Exception {
       Integer userID = 0;
       MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
       MultipartFile multipartFile = multipartRequest.getFile("Filedata");
       /** 寫文件前先讀出圖片原始高寬 **/
       byte[] bytes = multipartFile.getBytes();
       InputStream is = new ByteArrayInputStream(bytes);
       int width = 0; // 原始圖片寬
       int height = 0; // 原始圖片高
       try {
           BufferedImage bufimg = ImageIO.read(is);
           // 只有圖片才獲取高寬
           if (bufimg != null) {
               width = bufimg.getWidth();
               height = bufimg.getHeight();
           }
           is.close();
       } catch (Exception e) {
           e.printStackTrace();
           loger.error(e.getMessage());
           is.close();
           throw new Exception("uploadify上傳圖片讀取圖片高寬時發生異常!");
       }

       /** 拼成完整的文件保存路徑加文件 **/
       String originalFilename = multipartFile.getOriginalFilename(); // 文件全名
       String suffix = StringUtil.substringAfter(originalFilename, "."); // 後綴
       // 文件名轉碼
       // fileName = Base64.StringToBase64(fileName);
       // fileName = StringUtil.join(fileName, suffix);
       UploadFilePathVO uploadFile = UploadFilePathUtil.initFileUpload(userID, "test", suffix, width, height);
       File file = new File(uploadFile.getRealPath());
       multipartFile.transferTo(file); 工具

return uploadFile;
} post

4：自定義的上傳路徑工具類： spa

/**
   * 獲取圖片上傳路徑(處理高寬)
   *
   * @return
   */
   public static UploadFilePathVO initFileUpload(Integer userID, String imageType, String suffix, int width, int height) {
       String randomKey = RandomUtil.getRandomString(6);
       Date date = new Date();
       String dateStr = new SimpleDateFormat("yyyyMMdd").format(date);
       String timeStr = new SimpleDateFormat("HHmmssSSS").format(date);
       int hashcode = Math.abs(userID.hashCode() % 256);

       String relativePath = StringUtil.join(imageType, "/", hashcode, "/", userID, "/", dateStr, "/");
       String realPath = StringUtil.join(Constants.UPLOAD_REALPATH, "/", relativePath);

       File logoSaveFile = new File(realPath);
       if (!logoSaveFile.exists()) {
           logoSaveFile.mkdirs();
       }
       // 圖片文件名: 時間戳 + 隨機串 + 高寬
       String fileName = StringUtil.join(timeStr, randomKey, '_', height, '_', width, '.', suffix);
       UploadFilePathVO uploadFile = new UploadFilePathVO();
       uploadFile.setRelativePath(StringUtil.join(relativePath, fileName));
       uploadFile.setRealPath(StringUtil.join(realPath, fileName));
       return uploadFile;
   }
