Spring引导执行器：为什么Redis集群的健康状态不正确？

Question

我有一个使用Jedis配置redis集群的Spring Boot项目。配置文件如下：

application.yml文件：

redisclusterconfig.java文件：

@Configuration

private final Logger logger = LoggerFactory.getLogger(this.getClass());

@Value("${redis.cluster.host1}") private String HOST1;
@Value("${redis.cluster.port1}") private Integer PORT1;

@Value("${redis.cluster.host2}") private String HOST2;
@Value("${redis.cluster.port2}") private Integer PORT2;

@Value("${redis.cluster.host3}") private String HOST3;
@Value("${redis.cluster.port3}") private Integer PORT3;

@Value("${redis.cluster.host4}") private String HOST4;
@Value("${redis.cluster.port4}") private Integer PORT4;

@Value("${redis.cluster.host5}") private String HOST5;
@Value("${redis.cluster.port5}") private Integer PORT5;

@Value("${redis.cluster.host6}") private String HOST6;
@Value("${redis.cluster.port6}") private Integer PORT6;

@Bean
public JedisCluster jedisCluster() {
    Set<HostAndPort> jedisClusterNodes = new HashSet<HostAndPort>();
    //Jedis Cluster will attempt to discover cluster nodes automatically
    jedisClusterNodes.add(new HostAndPort(HOST1, PORT1));
    jedisClusterNodes.add(new HostAndPort(HOST2, PORT2));
    jedisClusterNodes.add(new HostAndPort(HOST3, PORT3));

    if(StringUtils.isNotBlank(HOST4)){
        jedisClusterNodes.add(new HostAndPort(HOST4, PORT4));
    }else{
        logger.warn("jedis cluster HOST4 not configured.");
    }

    if(StringUtils.isNotBlank(HOST5)){
        jedisClusterNodes.add(new HostAndPort(HOST5, PORT5));
    }else{
        logger.warn("jedis cluster HOST5 not configured.");
    }

    if(StringUtils.isNotBlank(HOST6)){
        jedisClusterNodes.add(new HostAndPort(HOST6, PORT6));
    }else{
        logger.warn("jedis cluster HOST6 not configured.");
    }
    JedisCluster jc = new JedisCluster(jedisClusterNodes, new JedisPoolConfig());
    return jc;
}

有没有什么东西我可能会错过使/健康状态恢复到“上升”状态？谢谢！

更多信息：我跟踪了启动，发现RedisHealthIndicator通过了一个错误的工厂，Host=localhost和port=6379，这应该是配置的集群主机和端口？

public RedisHealthIndicator(RedisConnectionFactory connectionFactory) {
    Assert.notNull(connectionFactory, "ConnectionFactory must not be null");
    this.redisConnectionFactory = connectionFactory;
}

最后，我通过重新配置redis来解决问题，如下所示：

Spring:Redis:Cluster:Nodes:-192.168.0.17:6390-192.168.0.17:6391-192.168.0.17:6392-192.168.0.9:6390-192.168.0.9:6391-192.168.0.9:6391-192.168.0.9:6391-192.168.0.9:6391-192.168.0.9:6391-192.168.0.9:6391-192.168.0.9:6391-192.168.0.9:6391-192.168.0.9:6391-192.168.0.9:6391-192.168.0.9:6391-19
