Hi,
I’m trying to integrate my Axon application with Spring cloud, and I see there’s a axon-distributed-commandbus-springcloud providing the router & connector for DistributedCommandBus.
I used the below configuration for the DistributedCommandBus:
@Primary
@Bean
public DistributedCommandBus distributedCommandBus(CommandRouter router, CommandBusConnector connector) {
DistributedCommandBus commandBus = new DistributedCommandBus(router, connector);
return commandBus;
}
@Bean
public SpringCloudCommandRouter springCloudCommandRouter(DiscoveryClient discoveryClient) {
return new SpringCloudCommandRouter(discoveryClient, new AnnotationRoutingStrategy());
}
@Bean
public SpringHttpCommandBusConnector springHttpCommandBusConnector(@Qualifier("localSegment") CommandBus localSegment,
RestTemplate restTemplate,
Serializer serializer) {
return new SpringHttpCommandBusConnector(localSegment, restTemplate, serializer);
}
But,during the integration, I got the error
17:41:53.273 [main] ERROR o.s.boot.SpringApplication - Application startup failed
