JSON.toJSONString 对象日期变为了时间戳

 ProduceJobLog produceJobLog = produceJobLogService.getProduceJobLog(user.getCompanyId(), produceJobLogId);
        outMap.put("fieldList", confProduceJobLogList);
        outMap.put("produceJobLogJSON",JSON.toJSONStringWithDateFormat(produceJobLog, "yyyy-MM-dd", SerializerFeature.WriteDateUseDateFormat));

使用

toJSONStringWithDateFormat()解决
