对java中的Hazelcast json值进行排序

import com.hazelcast.config.Config;
import com.hazelcast.core.Hazelcast;
import com.hazelcast.core.HazelcastInstance;
import com.hazelcast.core.IMap;
import com.hazelcast.query.Predicates;

import java.util.Map;

public class HazelcastJsonSortingExample {
    public static void main(String[] args) {
        // 创建Hazelcast实例
        Config config = new Config();
        HazelcastInstance hazelcastInstance = Hazelcast.newHazelcastInstance(config);

        // 获取一个分布式Map
        IMap<String, String> map = hazelcastInstance.getMap("myMap");

        // 添加JSON值到Map中
        map.put("1", "{\"name\":\"John\", \"age\":30}");
        map.put("2", "{\"name\":\"Alice\", \"age\":25}");
        map.put("3", "{\"name\":\"Bob\", \"age\":35}");

        // 使用Hazelcast的Predicates进行排序
        Map<String, String> sortedMap = map.entrySet()
                .stream()
                .sorted(Map.Entry.comparingByValue(Predicates.comparableJsonValue("age")))
                .collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue,
                        (oldValue, newValue) -> oldValue, LinkedHashMap::new));

        // 输出排序后的Map
        for (Map.Entry<String, String> entry : sortedMap.entrySet()) {
            System.out.println("Key: " + entry.getKey() + ", Value: " + entry.getValue());
        }

        // 关闭Hazelcast实例
        hazelcastInstance.shutdown();
    }
