SAE java应用读写文件（TmpFS和Storage）-----绝世好代码

public void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        request.setCharacterEncoding("gbk");
        PrintWriter out = response.getWriter();
        // 使用SaeUserInfo拿到改请求可写的路径
        String realPath = SaeUserInfo.getSaeTmpPath() + "/";
        try {
            // 使用common-upload上传文件至这个路径中
            boolean isMultipart = ServletFileUpload.isMultipartContent(request);
            if (!isMultipart)
                return;
            DiskFileItemFactory factory = new DiskFileItemFactory();
            ServletFileUpload upload = new ServletFileUpload(factory);
            upload.setFileSizeMax(1024 * 1024);
            List<FileItem> items = null;
            items = upload.parseRequest(request);
            for (FileItem item : items) {
                if (!item.isFormField()) {
                    File fullFile = new File(item.getName());
                    File uploadFile = new File(realPath, fullFile.getName());
                    item.write(uploadFile);
                    // 上传完毕后 使用SaeStorage往storage里面写
                    SaeStorage ss = new SaeStorage();
                    // 使用upload方法上传到域为image下
                    ss.upload("image", realPath + fullFile.getName(),
                            fullFile.getName());

                    out.print("upload file:" + realPath + fullFile.getName()
                            + "</br>");
                }
            }
            out.print("upload end...");
        } catch (Exception e) {
            out.print("ERROR:" + e.getMessage() + "</br>");
        } finally {
            out.flush();
            out.close();
        }
    }
