Jedis

Redis给Java语言提供了客户端API，称之为Jedis。Jedis API和Redis命令几乎是一样的。​ Jedis API特别简单，基本上都是创建对象调用方法即可。

（1）单机版

public void testStandalone()
{
    Jedis jedis = new Jedis("192.168.1.129",6379);
    jedis.set("name" ,"standalone");
    String value = jedis.get("name");
    System.out.println(value);
}

（2）带有连接池

public void testJedisPool()
{
    JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
    jedisPoolConfig.setMaxTotal(20);
    jedisPoolConfig.setMaxIdle(5);
    jedisPoolConfig.setMinIdle(3);

    JedisPool jedisPool = new JedisPool(jedisPoolConfig , "192.168.1.129",6379 );

    Jedis jedis = jedisPool.getResource();
    jedis.set("name" , "pool");

    String poolvalue = jedis.get("name");
    System.out.println(poolvalue);
}

（3）集群

public void testCluster()
{
    Set set = new HashSet();
    set.add(new HostAndPort("192.168.1.129",7001));
    set.add(new HostAndPort("192.168.1.129",7002));
    set.add(new HostAndPort("192.168.1.129",7003));
    set.add(new HostAndPort("192.168.1.129",7004));
    set.add(new HostAndPort("192.168.1.129",7005));
    set.add(new HostAndPort("192.168.1.129",7006));

    JedisCluster jedisCluster = new JedisCluster(set);
    jedisCluster.set("name" , "colony");

    String value = jedisCluster.get("name");
    System.out.println(value);
}
