Jedis-2.7.2 版本雖然支援連線叢集 Redis，但是僅僅支援 String 字串的儲存，並不支援 Map、Set、List，在這裡分享一個能夠支援複雜操作的方法。

import java.util.Set;

import org.apache.commons.pool2.impl.GenericObjectPoolConfig;

import redis.clients.jedis.HostAndPort;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisClusterCommand;
import
 
 redis.clients.jedis.JedisClusterConnectionHandler;
import redis.clients.jedis.JedisSlotBasedConnectionHandler;

public class BinaryJedisCluster {

    private int maxRedirections;
    private JedisClusterConnectionHandler connectionHandler;

    public BinaryJedisCluster(Set<HostAndPort> nodes, int
 
 timeout, int maxRedirections) {
        this(nodes, timeout, maxRedirections, new GenericObjectPoolConfig());
    }

    public BinaryJedisCluster(Set<HostAndPort> jedisClusterNode, int timeout, int maxRedirections,
            final GenericObjectPoolConfig poolConfig) {
        this.connectionHandler = new
 
 JedisSlotBasedConnectionHandler(jedisClusterNode, poolConfig, timeout);
        this.maxRedirections = maxRedirections;
    }

    public String set(final String key, final String value) {
        return new JedisClusterCommand<String>(connectionHandler, maxRedirections) {

            @Override
            public String execute(Jedis connection) {
                return connection.set(key, value);
            }
        }.run(key);
    }

    public String get(final String key) {
        return new JedisClusterCommand<String>(connectionHandler, maxRedirections) {

            @Override
            public String execute(Jedis connection) {
                return connection.get(key);
            }
        }.run(key);
    }
}

（注：這是簡化版的，具體程式碼並非原創，就不貼了。）

Map、Set、List 等類似 String，在 execute 方法中通過 Jedis 直接操作 Redis 即可。

在與 Spring 結合使用時，可以通過繼承 InitializingBean 來實現初始化注入。

    private BinaryJedisCluster jc;

    @Override
    public void afterPropertiesSet() throws Exception {
        Set<HostAndPort> set = new HashSet<HostAndPort>();
        set.add(new HostAndPort(host,port));
        ...
        jc = new BinaryJedisCluster(set, 5000, 6);
    }
