如何使用sadd操作检索添加后Redis集的所有密钥

我正在使用RedisCluster访问信息。这是我的代码:

package kafka;

import java.util.Collection;
import java.util.HashMap;
import java.util.HashSet;
import java.util.Map;
import java.util.Set;

import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisCluster;
import redis.clients.jedis.ScanParams;
import redis.clients.jedis.ScanResult;

public class RedisExample {

public static void main(String[] args) {
    JedisCluster connection = JedisConnection.getInstance().getconnection();
    connection.sadd("mykeys_key1", "attr1:string");
    connection.sadd("mykeys_key1", "attr2:string");
    connection.sadd("mykeys_key2", "attr1:string");
    connection.sadd("mykeys_key2", "attr2:string");
    connection.sadd("mykeys_key3", "attr1:string");
    connection.sadd("mykeys_key3", "attr2:string");
    System.out.println(connection.smembers("mykeys_key1"));

}

}

输出: [attr2:string, attr1:string]

**mykeys_*** .

我正在寻找类似的东西:

connection.smembers("mykeys_*") --- 这应该给我所有的钥匙,即。, mykeys_key3, mykeys_key2, mykeys_key1

Redis connection.smember("mykeys_key3") 获取单个集合。
