public Binding binding(FanoutExchange fanoutExchange, Queue autoDeleteQueue) {
return BindingBuilder.bind(autoDeleteQueue).to(fanoutExchange);
}
}
The client listens class
@Component
public class ConsumerListener {
@RabbitListener(queues = "my_queue")
public void reciveMessage(Message message){
String msg=new String(message.getBody());
