使用spring boot数据redis连接到redis集群问题

Question

我使用Spring Boot数据redis，使用版本2.1.3连接到redis集群。配置如下：

@Bean
@Primary
public RedisConnectionFactory myLettuceConnectionFactory(GenericObjectPoolConfig poolConfig) {
    RedisClusterConfiguration redisClusterConfiguration = new RedisClusterConfiguration();
    final List<String> nodeList = redisProperties.getCluster().getNodes();
    Set<RedisNode> nodes = new HashSet<RedisNode>();
    for (String ipPort : nodeList) {
        String[] ipAndPort = ipPort.split(":");
        nodes.add(new RedisNode(ipAndPort[0].trim(), Integer.valueOf(ipAndPort[1])));
    }
    redisClusterConfiguration.setPassword(RedisPassword.of(redisProperties.getPassword()));
    redisClusterConfiguration.setClusterNodes(nodes);
    redisClusterConfiguration.setMaxRedirects(redisProperties.getCluster().getMaxRedirects());
    LettuceClientConfiguration clientConfig = LettucePoolingClientConfiguration.builder()
            .commandTimeout(redisProperties.getTimeout())
            .poolConfig(poolConfig)
            .build();

    RedisClusterClient clusterClient ;

    LettuceConnectionFactory factory = new LettuceConnectionFactory(redisClusterConfiguration,clientConfig);
    return factory;
}

但是，在操作过程中，始终会按以下方式接收到WARN异常消息：

好吧，这似乎是莴苣How to map remote host & port to localhost using Lettuce的问题，但我不知道如何在spring boot数据redis中使用它。欢迎任何解决方案，谢谢

我已经找到了答案，所以让我们定义一个ClinentRourse：

 MappingSocketAddressResolver resolver = MappingSocketAddressResolver.create(DnsResolvers.UNRESOLVED ,
            hostAndPort -> {
                if(hostAndPort.getHostText().startsWith("172.31")){
                    return HostAndPort.of(ipStr, hostAndPort.getPort());
                }
                return hostAndPort;
            });

    ClientResources clientResources = ClientResources.builder()
            .socketAddressResolver(resolver)
            .build();

然后通过LettuceClientConfiguration.clientResources方法设置，使生菜正常工作。
