自己创建一个类JedisClusterFactory：

redis-config.properties：

address1=192.168.1.36:6379address2=192.168.1.37:6379address3=192.168.1.38:6379address4=192.168.1.40:6379address5=192.168.1.41:6379address6=192.168.1.42:6379

Java调用：

@Autowired
private JedisCluster jedisCluster;　　//jedisCluster就是对应的bean id 可以自动注入
System.out.println(jedisCluster.get("foo"));
System.out.println(jedisCluster.set("qq","222"));
System.out.println(jedisCluster.get("qq"));
