list转list<Map<String,Object>>

直接转换，把list集合替换就好



if (CollectionUtils.isNotEmpty(list)) {
    list.forEach(item -> {
        Map<String, Object> map = null;

        try {
            map = (Map<String, Object>) PropertyUtils.describe(item);
            map.remove("class");
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        } catch (InvocationTargetException e) {
            e.printStackTrace();
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
        }
        listMap.add(map);
    });

//下面是项目业务需要代码，时间转换用
    SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    String format = null;
    for (Map<String, Object> map : listMap) {
        for (Map.Entry<String, Object> stringObjectEntry : map.entrySet()) {
            if (stringObjectEntry.getValue() instanceof Long) {
                format = simpleDateFormat.format(stringObjectEntry.getValue());
                map.put(stringObjectEntry.getKey(), format);
            }
        }
    }
}
