我正在尝试使用Spring Integration和Docker上的Kafka实现以下场景：
轮询工作正常，我的应用程序设置似乎是正确的，因为应用程序启动时没有任何连接异常。
正如您在输出中看到的那样，KafkaProducerMessageHandler接收消息，但挂起“尝试向节点-1发送元数据请求”超过一分钟，然后抛出TimeoutException。
以下是链接所需的输出和代码：
这是我的应用程序设置：
KafkaConfig基于https://github.com/spring-projects/spring-integration-samples的Kafka示例和https://github.com/wurstmeister/kafka-docker的Kafka Docker容器。
感谢您的任何想法和建议!!!!

我们在您的日志中看到类似的内容：
227 --- [kafka-producer-network-thread | producer-1] org.apache.kafka.clients.NetworkClient : Sending metadata request ClientRequest(expectResponse=true, payload=null, request=RequestSend(header={api_key=3,api_version=0,correlation_id=23,client_id=producer-1}, body={topics=[test.topic]})) to node -1
2016-01-26 15:22:24.986 DEBUG 4227 --- [kafka-producer-network-thread | producer-1] org.apache.kafka.clients.NetworkClient : Trying to send metadata request to node -1
看起来你真的应该查看Broker日志。
首先它可能是：
kafka.common.InvalidTopicException: topic name TOPIC= is illegal, contains a character other than ASCII alphanumerics, '.', '_' and '-'
https://issues.apache.org/jira/browse/KAFKA-1884
因此，主题名称中的.是非法的。您可以将不兼容的Kafka版本与其客户端一起使用。 Spring Integration Kafka 1.3基于Kafka-0.8.2.2。
从另一方面来看，可能存在一些网络问题：Kafka 0.8.2.2 - Unable to publish messages

我是个傻瓜！
我的码头组成是：
kafka:
image: wurstmeister/kafka
ports:
- "9092:9092"
links:
- zookeeper:zk
environment:
KAFKA_ADVERTISED_HOST_NAME: 192.168.59.103
volumes:
- /var/run/docker.sock:/var/run/docker.sock
其中192.168.59.103是我的IP。我不得不把它改成localhost，现在看起来很好。
