根据不同的返回码来处理

//timestamp验证
Integer timestampResult = commonService.timestampValidDate(timestamp);
if(timestampResult == ConstantConfig.TIMESTAMP_VALIDDATE_FORMAT_ERROR){
ResponseUtil.responseObject2App(response, map, ResponseUtil.STATUS_ERROR_PARAM, "timestamp format  error" ,callback);
return;
}

if(timestampResult == ConstantConfig.TIMESTAMP_VALIDDATE_TIME_OUT){
ResponseUtil.responseObject2App(response, map, ResponseUtil.STATUS_TIME_OUT, "Time must be within 5 minutes" ,callback);
return;
}
if(timestampResult == ConstantConfig.TIMESTAMP_VALIDDATE_SYSTEM_ERROR){
ResponseUtil.responseObject2App(response, map, ResponseUtil.STATUS_FAIL, "system error" ,callback);
return;
}
