1、启动redis集群
2、导入jedis的相关jar
3、测试代码如下

/**
     * 集群test
     * @throws Exception
     */
    @Test
    public void test8() throws Exception {
        HashSet<HostAndPort> hashSet=new HashSet<>();
        hashSet.add(new HostAndPort("123.57.36.98", 7000));
        hashSet.add(new HostAndPort("123.57.36.98", 7001));
        hashSet.add(new HostAndPort("123.57.36.98", 7002));
        hashSet.add(new HostAndPort("123.57.36.98", 7003));
        hashSet.add(new HostAndPort("123.57.36.98", 7004));
        hashSet.add(new HostAndPort("123.57.36.98", 7005));
        JedisCluster jedisCluster=new JedisCluster(hashSet);
        jedisCluster.set("duan", "100");
        String kString=jedisCluster.get("duan");
        System.out.println(kString);
    }

测试结果如下
