Can @RabbitListener apply by condition

Question

I want create a RabbitListener when a property is present, but @ConditionOnProperty cannot combine with @RabbitListener. Now I have a workaround below. Does it exist any better method?

@Bean
@ConditionalOnProperty(name = "pmc.multiple.hypervisor.reply.routerkey.kvm")
public SimpleMessageListenerContainer kvmReplyQueueConsumer() {
    return getSimpleMessageListenerContainer(environment
            .getProperty("pmc.multiple.hypervisor.reply.routerkey.kvm"));
}

Did you actually try it? This works fine for me...

public static class ConditionalListener {

    @RabbitListener(queues="test.queue")
    public void listen(String foo) {
        System.out.println(foo);
    }

}

@ConditionalOnProperty("foo.enabled")
@Bean
public ConditionalListener foo() {
    return new ConditionalListener();
}

When run with -Dfoo.enabled=true I get messages; otherwise the bean is not declared.
