具有分布式查询模型的Axon Register Tracking Processor

Question

我使用axon和spring-boot实现了CQRS + ES应用程序。我使用单独的查询模型和命令模型应用程序。我使用rabbitmq从命令模式发布事件。它的工作正确。但跟踪处理器实现在我的应用程序中不起作用。

这是我的查询模型

@SpringBootApplication
public class SeatQueryPart1Application {
    public static void main(String[] args) {
        SpringApplication.run(SeatQueryPart1Application.class, args);
    }

    @Bean
    public SpringAMQPMessageSource statisticsQueue(Serializer serializer) {
        return new SpringAMQPMessageSource(new DefaultAMQPMessageConverter(serializer)) {
            @RabbitListener(exclusive = false, bindings = @QueueBinding(value = @Queue, exchange = @Exchange(value = "ExchangeTypesTests.FanoutExchange", type = ExchangeTypes.FANOUT), key = "orderRoutingKey"))
            @Override
            public void onMessage(Message arg0, Channel arg1) throws Exception {
                super.onMessage(arg0, arg1);
            }
        };
    }

    @Autowired
    public void conf(EventHandlingConfiguration configuration) {
        configuration.registerTrackingProcessor("statistics");
    }

}

这是一个事件处理程序类

@ProcessingGroup("statistics")
@Component
public class EventLoggingHandler {


    private SeatReservationRepository seatReservationRepo;
    public EventLoggingHandler(final SeatReservationRepository e) {
        this.seatReservationRepo = e;
    }

    @EventHandler
    protected void on(SeatResurvationCreateEvent event) {
        Timestamp timestamp = new Timestamp(System.currentTimeMillis());
        Seat seat=new Seat(event.getId(), event.getSeatId(), event.getDate(),timestamp ,true);
        seatReservationRepo.save(seat);
    }

}

这是yml配置

axon:
  eventhandling:
    processors:
      statistics.source: statisticsQueue

我该怎么做才对。（任何人都可以建议教程或代码示例）
