图片上传流提交的一种方式。

String urlFilePath = new String();urlFilePath = "图片路径";File direct = new File(filePath);DiskFileUpload dfu = new DiskFileUpload();dfu.setSizeMax(1024 * 1024 * 500);dfu.setSizeThreshold(1024 * 1024 * 5);dfu.setHeaderEncoding("UTF-8");dfu.setRepositoryPath(this.getServletContext().getRealPath("/"));List list = dfu.parseRequest(request);Iterator it = list.iterator();String lstr = Long.toString(System.currentTimeMillis());String fileName="";String imageUrl="";boolean flag=false;int i = 1;while (it.hasNext()) {try {FileItem item = (FileItem) it.next();if (!item.isFormField()) {fileName = lstr.substring(7)+i+item.getName().substring(item.getName().lastIndexOf("."));if (!direct.exists()) {direct.mkdirs();}InputStream choosestream = item.getInputStream();BufferedImage chooseimage = ImageUtils.getImage(choosestream);FileOutputStream fos = new FileOutputStream(filePath+ "/" + fileName);ImageIO.write(chooseimage, "jpg", fos);fos.close();choosestream.close();flag=true;i++;}else {if ("id".equals(item.getFieldName())) {new String(item.getString().getBytes("ISO-8859-1"), "UTF-8");}}} catch (Exception e) {System.err.println(e);}
