根据这个主题：
Kafka Spring Integration: Headers not coming for kafka consumer - 这对Kafka没有头文件支持
spring.cloud.stream.kafka.binder.headers将由 Binders 传输的自定义标头列表 . 默认值：空 .
我 can't 使用spring-cloud-stream-binder-kafka：1.2.0.RELEASE

我希望在接收端看到相同的消息 id 并获得 correlationId .
application.properties：
spring.cloud.stream.kafka.binder.headers=correlationId
spring.cloud.stream.bindings.newTest.destination=new_test
spring.cloud.stream.bindings.newTestCreated.destination=new_test
spring.cloud.stream.default.consumer.headerMode=embeddedHeaders
spring.cloud.stream.default.producer.headerMode=embeddedHeaders
发送消息：
@Publisher(channel = "testChannel")
public Object newTest(Object param) {
...
return myObject;
}

是的，它确实：http://docs.spring.io/spring-cloud-stream/docs/Chelsea.SR2/reference/htmlsingle/index.html#_consumer_properties
但这已经是Spring Cloud Stream的故事，而不是Spring Kafka本身 .
