use spring boot data redis 连接redis集群问题

Question

我使用springboot data redis连接redis集群，使用2.1.3版本，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;
}

但是在运行过程中，总会收到如下WARN异常信息：

嗯，这个好像是lettuce的问题，How to map remote host & port to localhost using Lettuce，但是不知道如何在spring boot data redis中使用。欢迎任何解决方案，谢谢

我已经找到答案了，那么让我们像这样定义一个 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方法设置进去，生菜就正常工作了。
