我正试图用SpringCloudStream向Kafka发送消息,但是 send
方法产生以下错误:
Caused by: java.lang.IllegalArgumentException: Magic v1 does not support record headers
at org.apache.kafka.common.record.MemoryRecordsBuilder.appendWithOffset(MemoryRecordsBuilder.java:403) ~[kafka-clients-1.0.0.jar:na]

我在docker容器中运行kafka,发出命令:
docker run -p 2181:2181 -p 9092:9092 --env ADVERTISED_HOST=127.0.0.1 --env ADVERTISED_PORT=9092 spotify/kafka
但是如果我使用springkafka而不是springcloudstream,我就能够消费和生成消息。那么,Spring Cloud流有什么问题呢?

发生这种情况是因为客户端/代理版本不匹配。我猜您使用的是ApacheKafka版本0.10.x。必须使用ApacheKafka0.11.x或更高版本才能与SpringCloudStream(来自版本2)一起使用。
