如何对List(Map)进行Stream排序

 public void sortLastOnlineList(CloudRInfoPo cloudRInfoPo, List<Map<String, Object>> result) {
        if (!StringUtils.isEmpty(cloudRInfoPo.getDuration()) || "desc".equals(cloudRInfoPo.getSort())) {
            result.sort(Comparator.comparing((Map<String, Object> h) -> ((String) h.get("lastOnlineTime"))));  //正序
        }
        if (!StringUtils.isEmpty(cloudRInfoPo.getDuration()) || "asc".equals(cloudRInfoPo.getSort())) {
            result.sort(Comparator.comparing((Map<String, Object> h) -> ((String) h.get("lastOnlineTime"))).reversed()); //倒叙
        }
    }

别把我的<map>给隐藏掉啊. 审核小姐姐...
