getClusterConnection.clusterGetNodes 始终返回 1 个节点

问题描述 投票：0回答：1

我的配置如下：

spring.data.redis.password=...
spring.data.redis.username=default
spring.data.redis.ssl.enabled=false
spring.data.redis.cluster.nodes=127.0.0.1:16379,127.0.0.1:17379,127.0.0.1:18379,127.0.0.1:19379,127.0.0.1:20379,127.0.0.1:21379

豆子看起来像：

@Bean
public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
    RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
    redisTemplate.setConnectionFactory(redisConnectionFactory);
    redisTemplate.setKeySerializer(new StringRedisSerializer());
    redisTemplate.setHashKeySerializer(new StringRedisSerializer());
    redisTemplate.setHashKeySerializer(new JdkSerializationRedisSerializer());
    redisTemplate.setValueSerializer(new JdkSerializationRedisSerializer());
    redisTemplate.setEnableTransactionSupport(true);
    redisTemplate.afterPropertiesSet();
    return redisTemplate;
}

docker-compose 看起来像：

  redis-cluster_data-3:
    driver: local
  redis-cluster_data-4:
    driver: local
  redis-cluster_data-5:
    driver: local

最后当我尝试通过以下方式获取所有节点时：

    redisTemplate.getConnectionFactory().getClusterConnection()
            .clusterGetNodes()
            .forEach(x -> System.out.println(x.getHost() + ":" + x.getPort()));

它总是返回 1 个节点，如 

127.0.0.1:19379
。好的，每次运行节点都会发生变化，但我的期望是 6 个节点。有什么建议吗？

解决了添加总线端口的问题和重要注意：

bus-port = redis-port + 10000
否则它不起作用

这是我最终的 docker-compose：
