Question

我有一个带有Spring AMQP的AMQP项目。 RabbitMQ服务器不是我的，所以我无法控制它。当我的应用程序启动时，它会创建一个这样的私有响应队列：

@Bean(name="myAnonymousResponseQueue")
public Queue myAnonymousResponseQueue() 
{       
    Queue q = myAmqpAdmin().declareQueue();
    return q;
}

我有一个像这样的SimpleMessageListenerContariner：

    @Bean 
    public SimpleMessageListenerContainer myResponseMessageListenerContainer() 
    {
        SimpleMessageListenerContainer container = new SimpleMessageListenerContainer(myConnectionFactory());
        container.setQueues(myAnonymousResponseQueue());
        container.setMessageListener(myRabbitTemplate());
        container.setAcknowledgeMode(AcknowledgeMode.AUTO);
        container.setMessageConverter(myMessageConverter());
        container.setErrorHandler(myResponseErrorHandler());
        container.setAutoStartup(true);
        container.setRabbitAdmin(myAmqpAdmin());
        return container;
    }

我最近遇到了连接问题（ShutdownSignalException）。问题是我无法重新生成私有队列。首先，这是连接错误：

但是，当连接恢复后，无法重新创建专用队列：

最后我有了这个：

    at com.rabbitmq.client.impl.ChannelN.close(ChannelN.java:554)

    at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source)
    at java.lang.Thread.run(Unknown Source)

因此AMQP连接正常，但私有队列不是。

我不明白为什么会这样。我如何获得更多信息？是否可以从此错误中恢复？

由于

----------------（28/11/2016）-----------

我以这种方式定义匿名队列的原因是：

@Bean(name="myAnonymousResponseQueue")
    public Queue myAnonymousResponseQueue() 
    {       
        return new AnonymousQueue(new Base64UrlNamingStrategy("amq.gen-")); 
    }

服务器不允许我创建它，我收到以下错误：

|28-11-2016 08:43:13.203|INFO |org.springframework.amqp.rabbit.core.RabbitAdmin|initialize|RabbitAdmin.java|493||Auto-declaring a non-durable, auto-delete, or exclusive Queue (amq.gen-JUYnhLX2SpqNoJT6ioB8GA) durable:false, auto-delete:true, exclusive:true.

那么，AmqpAdmin（）。declareQueue（）和AnonymousQueue之间的区别是什么？经纪人不允许为队列命名是否可行？

现在我觉得我理解这个问题。我认为我的用户只能创建名为“amq.gen-”的队列。如果我尝试使用任何其他名称：

com.rabbitmq.client.ShutdownSignalException: channel error; protocol method: #method<channel.close>(reply-code=403, reply-text=ACCESS_REFUSED - access to queue '4788a39b-fffe-4eae-b252-8d842234a018' in vhost 'sob' refused for user 'USER', class-id=50, method-id=10)

com.rabbitmq.client.ShutdownSignalException: channel error; protocol method: #method<channel.close>(reply-code=403, reply-text=ACCESS_REFUSED - access to queue 'amq-_zoOEt5jTcqMduGWNyJ4Zg' in vhost 'sob' refused for user 'USER', class-id=50, method-id=10)

所以，如果我只能使用经纪人生成队列，我需要在重新接收时重新声明它，我该怎么办？

再次感谢你。

修改

我正在尝试应用解决方法。我已经使用：

声明了一个ConnectionListener

@Override
public void onCreate(Connection arg0) 
{
    myResponseMessageListenerContainer.stop();
    String[] colaAnterior = myResponseMessageListenerContainer.getQueueNames();

    Queue q = myAmqpAdmin.declareQueue();
    q.setAdminsThatShouldDeclare(myAmqpAdmin);
    q.setShouldDeclare(true);

    myResponseMessageListenerContainer.addQueueNames(q.getName());

    myResponseMessageListenerContainer.removeQueueNames(colaAnterior);
    myResponseMessageListenerContainer.initialize();
    myResponseMessageListenerContainer.start(); 
}

但现在我有这个错误：

我一直在努力，但有关如何修复它的任何想法？

由于

编辑2

现在我有了这个：

@Override
    public void onCreate(Connection arg0) 
    {
        myResponseMessageListenerContainer.stop();

        String[] colaAnterior = myResponseMessageListenerContainer.getQueueNames();
        Queue q = myAmqpAdmin.declareQueue();

        log.info(" ------ RESPONSE QUEUE -> OLD NAME: " + Arrays.asList(colaAnterior) + " NEW NAME: " + q.getName());

        myResponseMessageListenerContainer.addQueueNames(q.getName());
        myRabbitTemplate.setReplyAddress(q.getName());
        myRabbitTemplate.setQueue(q.getName());

        myResponseMessageListenerContainer.removeQueueNames(colaAnterior);

        myResponseMessageListenerContainer.shutdown();
        myResponseMessageListenerContainer.initialize();
        myResponseMessageListenerContainer.start(); 
    }

但是容器不会停留在最后定义的队列中：

|30-11-2016 16:32:19.996|INFO |es.omie.amqp.config.listener.XBIDConnectionListener|onCreate|XBIDConnectionListener.java|42|| ------ RESPONSE QUEUE -> OLD NAME: [amq.gen-uTp6TCP66x2AlXUmQzqz8g] NEW NAME: amq.gen-DOwEn8WKz_9ymCBQFiMDNg

我看不到新的队列名称。

我可以在日志中看到在创建连接之前重启容器：

Restarting Consumer: tags=[{amq.ctag-KYCURTkS4EevXHQtrpYV9Q=amq.gen-uTp6TCP66x2AlXUmQzqz8g}]

但不是在启动方法之后。

Answer 1

由于这个原因，Spring AMQP提供了自己的AnonymousQueue;它的随机名称将被保留，因此，当重新建立连接时，将重新创建声明。您的代码允许代理命名队列。

但是，您应该让RabbitAdmin自动处理声明，而不是自己处理。

@Bean
public Queue myAnonymousResponseQueue() {
    return new AnonymousQueue();
}

当admin（也必须是@Bean）检测到初始连接（或重新连接）时，它将声明所有此类队列。

请参阅Configuring the Broker。

修改

如果您的管理员不允许您为队列命名（您不能使用amq.gen-作为前缀），则必须重新声明代理生成的队列并使用新的队列更新容器队列中。

将ConnectionListener添加到连接工厂;当调用onCreate()时（因为建立了新连接），停止容器，重新声明队列，将容器的队列更新为新名称;启动容器。

请记住，删除连接后，临时队列中的所有邮件都将丢失。

由于可能在容器线程上调用侦听器，因此您应该将此工作移交给另一个线程;否则会有延迟。
