Redis java client ==> Jedis

https://github.com/xetorthio/jedis

Jedis is a blazingly small and sane Redis java client.

Jedis was conceived to be EASY to use.

Jedis is fully compatible with redis 2.8.x and 3.0.x.

小、功能健全、简单易用、全面兼容

1. 单客户端

<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>2.7.2</version>
</dependency>

Jedis jedis = new Jedis("localhost");
jedis.set("foo", "bar");
String value = jedis.get("foo");

2. 集群

Set<HostAndPort> jedisClusterNodes = new HashSet<HostAndPort>();
//Jedis Cluster will attempt to discover cluster nodes automatically
jedisClusterNodes.add(new HostAndPort("127.0.0.1", 7379));
JedisCluster jc = new JedisCluster(jedisClusterNodes);
jc.set("foo", "bar");
String value = jc.get("foo");

Spring 集成
