resteasy 上傳圖檔

用作備忘，

代碼如下：

@POST
  @Path("upload")
  @Consumes(MediaType.MULTIPART_FORM_DATA)
  @Produces(MediaType.APPLICATION_JSON)
  public JSONObject upload1(MultipartFormDataInput formDataInput) {
    JSONObject json = new JSONObject();
    Integer isSuccess = Constants.INTEGER_ZERO;
    FileOutputStream fop = null;
    InputStream inputStream = null;
    try {
      //送出的form表單
      Map<String, List<InputPart>> uploadForm = formDataInput.getFormDataMap();
      //      //如果有中文參數的話，用下面方法防止亂碼
      //      //中文表單資料
      //      InputPart zhongweninputParts = uploadForm.get("title").get(0);
      //      //解決中文亂碼
      //      zhongweninputParts.setMediaType(MediaType.TEXT_PLAIN_TYPE);
      //圖檔
      InputPart imgfileInputParts = uploadForm.get("imgfile").get(0);
      inputStream = imgfileInputParts.getBody(InputStream.class, null);
      String img = "D:\\" + System.currentTimeMillis() + ".png";
      byte[] bytes = IOUtils.toByteArray(inputStream);
      fop = new FileOutputStream(img);
      fop.write(bytes);
      json.put("img", img);
    } catch (Exception e) {
      json.put("isSuccess", Constants.INTEGER_ZERO.toString());
      logger.info("上傳圖檔出錯");
      logger.info(e);
    } finally {
      try {
        fop.flush();
        fop.close();
        inputStream.close();
      } catch (IOException e) {
        e.printStackTrace();
      }
      json.put("isSuccess", isSuccess.toString());
    }
    return json;
  }
