对List <Map <String,Object >>进行排序

import java.util.*;

public class Main {
    public static void main(String[] args) {
        List<Map<String, Object>> list = new ArrayList<>();

        Map<String, Object> map1 = new HashMap<>();
        map1.put("name", "Alice");
        map1.put("age", 30);
        list.add(map1);

        Map<String, Object> map2 = new HashMap<>();
        map2.put("name", "Bob");
        map2.put("age", 25);
        list.add(map2);

        Map<String, Object> map3 = new HashMap<>();
        map3.put("name", "Charlie");
        map3.put("age", 35);
        list.add(map3);

        // 根据 "age" 键进行排序
        list.sort(Comparator.comparing(m -> (Integer) m.get("age")));

        // 如果你想要降序排序，可以使用 reversed() 方法
        // list.sort(Comparator.comparing(m -> (Integer) m.get("age")).reversed());

        System.out.println(list);
    }
