对List<Map<String, Object>>集合排序

private void mySort(List<Map<String, Object>> list) {
        //list为待排序的集合，按SEQ字段排序
        Comparator<Map<String, String>> mapComprator = new Comparator<Map<String, String>>() {
            @Override
            public int compare(Map<String, String> o1,
                    Map<String, String> o2) {
                if (Integer.valueOf(o1.get("SEQ").toString()) > Integer.valueOf(o2.get("SEQ").toString())) {
                    return 1;  //此处是按降序排序
                } else {
                    return -1;
                }
            }
        };
        Collections.sort((List)list, mapComprator);
    }
