自己创建一个类JedisClusterFactory：

            ex.load(this.addressConfig.getInputStream());
            HashSet haps = new HashSet();

                    haps.add(hap);

            }

            return haps;

        } catch (Exception var10) {
            throw new Exception("解析 jedis 配置文件失败", var10);
        }
    }

    public void afterPropertiesSet() throws Exception {
        Set haps = this.parseHostAndPort();

redis-config.properties：

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

Java调用：

@Autowiredprivate 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"));
