Added default spring boot added Enable binding

@EnableBinding({MessageChannels.class})
@SpringBootApplication
public class Configissue1124Application {

    public static void main(String[] args) {
        SpringApplication.run(Configissue1124Application.class, args);
    }

}

Now simple straightforward massage channel to to dispatch massage

interface MessageChannels {


    @Input("saviyntSampleQueueA")
    SubscribableChannel queueA();

    @Input("saviyntSampleQueueB")
    SubscribableChannel queueB();
}

Answer 1

The AMQP protocol (or RabbitMQ REST API) provides no mechanism to provision virtual hosts from the client.

Virtual hosts must be provisioned manually on the server.
