jedis 连接redis

一，  单机版连接

@Test
    public void testJedis() {
        //1. 创建jedis 对象
        Jedis jedis = new Jedis("192.168.88.142", 6379);
        //2. 直接调用 jedis对象的方法，  方法名称和 redis的命令一致
        jedis.set("k1", "v1");
        System.out.println(jedis.get("k1"));
        //3.关闭jedis
        jedis.close();
    }

/**
     * 使用连接池
     */
    public void TestJedisPool() {
        //创建连接池
        JedisPool pool = new JedisPool("192.168.88.142", 6379);

        //从连接池中获得jedis对象
        Jedis jedis = pool.getResource();

        System.out.println(jedis.get("k1"));
        //关闭jedis
        jedis.close();
        //关闭连接池
        pool.close();
    }

二，  连接集群

/**
     * 链接集群
     */
    @Test
    public void testJedisCluster() {
        HashSet<HostAndPort> node = new HashSet();
        node.add(new HostAndPort("192.168.88.142",7001));
        node.add(new HostAndPort("192.168.88.142",7002));
        node.add(new HostAndPort("192.168.88.142",7003));
        node.add(new HostAndPort("192.168.88.142",7004));
        node.add(new HostAndPort("192.168.88.142",7005));
        node.add(new HostAndPort("192.168.88.142",7006));

        JedisCluster cluster = new JedisCluster(node);
        System.out.println(cluster.get("k1"));
        cluster.close();
    }
