文件上传示例（上传到amazon s3服务器）
action调用上传工具类
@Action(value = "files-upload", results = {@Result(name = SUCCESS, location = COMMON_PAGES_ROOT + "/noData.jsp")}) public String filesUpload() { try {// 拦截器生成的临时文件 baseLog.info("===start to upload:"+uploadFile.getName()); ...... if (StringUtils.isEmpty(upload(FILE_ACTION_URL))) { setStatus(ERROR_CODE_SYSTEM); return SUCCESS; } JSONArray array = JSONArray.fromObject(upload(FILE_ACTION_URL)); List<TwitterFile> allFiles = new ArrayList<>(); for (Object o : array) { JSONObject json = JSONObject.fromObject(o); if (json != null) { TwitterFile allFile = jsonToFiles(json.optString("url"), uploadFile.length()); allFiles.add(allFile); break; } } ......FILE_ACTION_URL 是本地临时存放的相对路径，如： FILE_ACTION_URL= /upload/file
