Axon Register Tracking Processor with distributed query model - spring-boot

Question

I had implement CQRS+ES application using axon and spring-boot. I use separate query model and command model application. I use rabbitmq to publish event from command mode. It works correct. But tracking Processor implementation is not work in my application.
This is my query model
#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");
}
}
this is a event handler class
#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);
}
}
this is yml configuration
axon:
eventhandling:
processors:
statistics.source: statisticsQueue
How can i do it correct. (Can anyone suggest tutorial or code sample)

Answer 1

The SpringAMQPMessageSource is a SubscribableMessageSource. This means you cannot use a tracking event processor to process messages. It is only compatible with a Subscribable Event Processor.
Removing configuration.registerTrackingProcessor("statistics"); and leaving it to the default (subscribing) should do the trick.
