list根据字段排序java java list根据某个值排序

例子：Java中对list map根据map某个key值进行排序的方法

List<Map<String, Object>> productAttributeColors = new ArrayList<>();

//productAttributeColors 按 position 重新排序 start
Collections.sort(productAttributeColors, new Comparator<Map<String, Object>>() {
    public int compare(Map<String, Object> map1, Map<String, Object> map2) {
    Integer position1 = Integer.valueOf(map1.get("position").toString()) ;
    Integer position2 = Integer.valueOf(map2.get("position").toString()) ;
    return position1.compareTo(position2);
    }
});
//productAttributeColors 按 position 重新排序 end
