Spring rabbitmq 将新队列附加到现有侦听器
Spring rabbitmq attaching new queue to existing listener
我需要动态声明新队列并将其分配给我现有的侦听器。
我有一个这样声明的监听器:
@Component
public class AccountListener {
@RabbitListener(id = "foobar")
public String foo(String a) {
System.out.println(a);
return a + "xxx";
}
}
我可以使用 RabbitListenerEndpointRegistry
检索此侦听器,但如何通过队列公开它?
@Autowired
private AmqpAdmin rabbit;
@Autowired
private RabbitListenerEndpointRegistry registry;
public void exposeQueue(String queueName) throws Exception {
Queue queue = new Queue(queueName, false);
rabbit.declareQueue(queue);
SimpleMessageListenerContainer listener = (SimpleMessageListenerContainer) registry.getListenerContainer("foobar");
// Attach $listener to $queue here
}
您应该将队列添加到容器的队列列表中:
listener.addQueueNames(queueName);
addQueueNames() method will add the queue to the container at runtime. See here 了解更多信息。
