Hello @joram
it’s really simple at the moment.
I have the following channel
{
"type": "kafka",
"channelType": "inbound",
"deserializerType": "json",
"topics": [
"settlementOrderFile-in-0"
],
"channelEventKeyDetection": {
"jsonField": "eventName"
},
"name": "Settlement Order File",
"key": "settlementOrderFile"
}
and the following event
{
"payload": [
{
"name": "filename",
"type": "string"
},
{
"name": "file",
"type": "json"
},
{
"name": "eventName",
"type": "string"
}
],
"name": "Test Event Name",
"key": "testEvent-Name"
}
I can successfully subscribe to the topic via code with the following two classes
@Configuration
public class KafkaChannelRegistrationConfig {
final EventRegistry eventRegistry;
final EventRepositoryService eventRepositoryService;
final KafkaChannelDefinitionProcessor kafkaChannelDefinitionProcessor;
@Autowired
public KafkaChannelRegistrationConfig(
BeanFactory beanFactory,
KafkaChannelDefinitionProcessor kafkaChannelDefinitionProcessor
) {
this.kafkaChannelDefinitionProcessor = kafkaChannelDefinitionProcessor;
this.kafkaChannelDefinitionProcessor.setBeanFactory(beanFactory);
EventRegistryEngine eventRegistryEngine = EventRegistryEngines.getDefaultEventRegistryEngine();
this.eventRepositoryService = eventRegistryEngine.getEventRepositoryService();
this.eventRegistry = eventRegistryEngine.getEventRegistry();
}
@Bean
public SettlementOrderFileTopicCreator settlementOrderFileTopicCreator() {
return new SettlementOrderFileTopicCreator(eventRepositoryService, eventRegistry, kafkaChannelDefinitionProcessor);
}
}
@Slf4j
public class SettlementOrderFileTopicCreator {
public SettlementOrderFileTopicCreator(
EventRepositoryService eventRepositoryService,
EventRegistry eventRegistry,
KafkaChannelDefinitionProcessor kafkaChannelDefinitionProcessor
) {
ChannelModel channelModel = eventRepositoryService.getChannelModelByKey("settlementOrderFile");
kafkaChannelDefinitionProcessor.registerChannelModel(channelModel, "", eventRegistry, eventRepositoryService, false);
}
}
Then I try to catch the event with the following two classes
but that didn’t work, no event arrived.
@SpringBootApplication
public class SettlementFileServiceApplication {
public static void main(String[] args) {
SpringApplication.run(SettlementFileServiceApplication.class, args);
}
@Bean
public EngineConfigurationConfigurer<SpringAppEngineConfiguration> customAppEngineConfigurer(SettlementFileProcessingService settlementFileProcessingService) {
return engineConfiguration -> {
engineConfiguration.addEventRegistryEventConsumer(settlementFileProcessingService.getConsumerKey(), settlementFileProcessingService);
};
}
}
@SpringBootApplication
public class SettlementFileServiceApplication {
public static void main(String[] args) {
SpringApplication.run(SettlementFileServiceApplication.class, args);
}
@Bean
public EngineConfigurationConfigurer<SpringAppEngineConfiguration> customAppEngineConfigurer(SettlementFileProcessingService settlementFileProcessingService) {
return engineConfiguration -> {
engineConfiguration.addEventRegistryEventConsumer(settlementFileProcessingService.getConsumerKey(), settlementFileProcessingService);
};
}
}
Up to this point I do not use the *.event and *.channel Files. I subscribe to the topic via code.
On the log-output i can see that my application successfully subscribe to the topic

If i put the two files (*.channel and *.event i postet before) into the eventregistry-folder on the classpath all works fine.
The Process looks like this
