redis集群配置类

在spring boot项目中整合了redis，redis采用集群的方式，在项目中怎么实现配置类呢？里面的序列化是什么？
@Configuration
public class AppConfig {
    @Autowired
    ClusterConfigurationProperties clusterProperties;

    @Bean
    public RedisConnectionFactory connectionFactory() {
        return new JedisConnectionFactory(new RedisClusterConfiguration(clusterProperties.getNodes()));
    }

    @Bean
    public RedisSerializer<?> fastJsonRedisSerializer() {
        return new FastJsonRedisSerializer<>(Object.class);
    }

    @Bean("stringRedisTemplate")
    public RedisTemplate stringRedisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<String,?> redisTemplate = new StringRedisTemplate();
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }



}



@Component
@ConfigurationProperties(prefix = "spring.redis.cluster")
public class ClusterConfigurationProperties {
    // spring.redis.cluster.nodes=127.0.0.1:7000,127.0.0.1:7001,127.0.0.1:7002,127.0.0.1:7003,127.0.0.1:7004,127.0.0.1:7005
    List<String> nodes;

    public List<String> getNodes() {
        return nodes;
    }

    public void setNodes(List<String> nodes) {
        this.nodes = nodes;
    }



}
