Java 8 如何快速的将List<T>转换成List<Map<String,Object>>

实际开发过程中，经常会遇到需要将List<T>转换List<Map<String,Object>>的情况，那么你们都是用什么方法实现的呢？

下面是我开发过程中使用的方法，还望大佬看后轻喷。

List<Map<String,Object>> monitorVoMapList = Optional.ofNullable(monitorVoLists).orElseGet(ArrayList::new)
                .stream().map(monitorVO -> {
                    Map<String, Object> monitorVoMap = BeanCopyUtil.beanToMap(monitorVO);
                    List<Map<String, Object>> sensorDataList = sensorService
                            .listMaps(new LambdaQueryWrapper<SensorDetail>()
                                    .select(SensorDetail::getDataInfo, SensorDetail::getSensorType)
                                    .eq(SensorDetail::getStationSn, monitorVO.getStationSn()));
                    sensorDataList.forEach(sensorData -> {
                        JSONObject data = new JSONObject();
                        JSONObject json = JSON.parseObject(sensorData.get("data_info") + "");
                        json.keySet().forEach(key -> data.put(key, json.getJSONObject(key).getString("value")));
                        monitorVoMap.put(sensorData.get("sensor_type") + "", data);
                    });
                    return monitorVoMap;
                }).collect(Collectors.toList())

    public static <T> Map<String, Object> beanToMap(T bean) {
        Map<String, Object> map = Maps.newHashMap();
        if (bean != null) {
            BeanMap beanMap = BeanMap.create(bean);
            for (Object key : beanMap.keySet()) {
                map.put(key + "", beanMap.get(key));
            }
        }
        return map;
    }

上面的方法没有数据结构看起来可能比较吃力，下面就将数据贴出来

sensorDataLists数据格式

    "data_info": {
      "03H_C": {
        "time": "2022-08-23 10:55:00",

        "value": "1.021"
      }
    },
    "sensor_type": "H1600"

最终处理后返回数据格式
