目前我在同一个spring引导应用程序中配置producer和consumer，但是触发消息的spring云流没有通过kafka（我正在用kafka控制台consumer监视消息），但是consumer仍然收到消息（使用与producer相同的线程）。
如果我删除了应用程序中的consumerhandler（@streamlistener），生产者就会成功地将消息发送给kafka。
这个有什么配置吗？默认情况下，我需要spring云流向kafka发送消息。
生产者和消费者配置：

@Component
public interface NotificationProcessor {

    String EMAIL_NOTIFICATION = "email-notification";
    @Input(EMAIL_NOTIFICATION)
    SubscribableChannel receiveEmail();
    @Output(EMAIL_NOTIFICATION)
    MessageChannel sendEmail();
}

以下是我的一些配置：

spring:
  cloud:
    stream:
      kafka:
        binder:
          autoAddPartitions: true
          brokers: ${KAFKA_BROKERS:localhost:9092}
          auto-create-topics: true
          configuration:
            auto.offset.reset: latest
      bindings:
        email-notification:
          group: ${EMAIL_GROUP:email-group-notification}
          destination: ${EMAIL_TOPIC:email-notification}
          contentType: application/json
          producer:
            partitionCount: 9
          consumer:
            partitioned: true
            concurrency: 3
      instance-count: 1
      instance-index: 0

触发发送消息的api：

@RestController
@RequestMapping("/api")
public class TestResource {
    private final Logger log = LoggerFactory.getLogger(TestResource.class);

    private final NotificationProcessor notificationProcessor;
    public TestResource(NotificationProcessor notificationProcessor) {
        this.notificationProcessor = notificationProcessor;
    }

    @ApiOperation(value = "Test api")
    @GetMapping(value = "/send-email2", produces = APPLICATION_JSON_VALUE)
    public ResponseEntity<Boolean> test2() {
        EmailMessage test =  EmailMessage.builder()
                .to(Arrays.asList(Receiver.builder().email("test@nomail.com").build())
                ).type(EContentType.JSON)
                .build();
        log.info("send email message to kafka");
        notificationProcessor.sendEmail().send(MessageBuilder.withPayload(test).build());
        return ResponseEntity.ok(Boolean.TRUE);
    }
}

和使用者处理程序：

@EnableBinding(NotificationProcessor.class)
public class NotificationProducer {

    private final Logger log = LoggerFactory.getLogger(NotificationProducer.class);

    public NotificationProducer(){}

    @StreamListener(NotificationProcessor.EMAIL_NOTIFICATION)
    public void receiveEmail(@Payload Message<EmailMessage> message)  {
        log.info("Receive email message from kafka");
        EmailMessage emailMessage = message.getPayload();
    }
}
