我正在使用SpringCloudBus将事件发布到kafka，以便另一个示例可以侦听相同的事件。事件正在触发，但未发布到Kafka。我用的是Spring Cloud巴士和Spring Cloud流。
版本：spring boot:2.0，spring cloud bus:2.0.0，spring cloud stream:2.0.1
应用程序.yml：

server:
  port: 7711
spring:
  application:
    index: ${random.uuid}
  cloud:
    bus:
      enabled: true
    stream:
      kafka:
        binder:
          brokers: localhost:9092
      bindings:

发布事件：

@Autowired
private ApplicationContext context;

@StreamListener(ConsumerStream.INPUT)
public void messageConsumer(@Payload String jsonValue, @Headers MessageHeaders header) {

    try {
        log.info("Enter in Consumer->messageConsumer()");
        final String myUniqueId = context.getId();
        context.publishEvent(new MessagingEventBus(this,myUniqueId,header));
    } catch (Exception e) {
        log.error("Exception caught while processing the request :", e);
    }
}

事件类别：

@Slf4j
public class MessagingEventBus extends RemoteApplicationEvent {

    private MessageHeaders header;

    // Must supply a default constructor and getters/setters for deserialization
    public MessagingEventBus() {
    }

    public MessagingEventBus(Object source, String originService, MessageHeaders header) {
        // source is the object that is publishing the event
        // originService is the unique context ID of the publisher
        super(source, originService);
        this.header = header;
    }

}

事件侦听器：

@Component
@Slf4j
public class MessagingEventBusListener implements ApplicationListener<MessagingEventBus> {

    @Override
    public void onApplicationEvent(MessagingEventBus messagingEventBus) {
       log.info("Messaging Event Bus Listener called");
    }
}
