Question

我使用 Spring Cloud Stream 1.3.2.RELEASE 向Kafka发布String消息。当我使用命令行Kafka consumer或 Spring Kafka @KafkaListener使用消息时，contentType标头始终附加到消息正文中。

问题：

有没有办法摆脱嵌入式标题？

Spring Cloud Stream作为制作人

private void send() {
    channel.test().send(MessageBuilder.withPayload("{\"foo\":\"bar\"}").build());
}

命令行Kafka消费者

$ bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic test
�
 contentType
            "text/plain"{"foo":"bar"}

Spring Kafka作为消费者

@KafkaListener(topics = "test")
public void receive(Message message){
    log.info("Message payload received: {}", message.getPayload());
}

2018-05-16 07:12:05.241  INFO 19475 --- [ntainer#0-0-C-1] com.demo.service.Listener  : Message payload received: �contentType"text/plain"{"foo":"bar"}

@KafkaListener(topics = "test")
public void receive(@Payload String message){
    log.info("Message payload received: {}", message);
}

2018-05-16 07:16:14.313  INFO 19747 --- [ntainer#0-0-C-1] com.demo.service.Listener  : Message payload received: �contentType"text/plain"{"foo":"bar"}

请参阅headerMode绑定属性：https://docs.spring.io/spring-cloud-stream/docs/Ditmars.SR3/reference/htmlsingle/#_properties_for_use_of_spring_cloud_stream。您需要为发送邮件的目的地将其设置为raw。
