Question

我在JMS项目中工作，我们使用Message Driven bean（@MessageDriven），Server是JBoss 7.我们在会话中添加了作业，我们添加了JmsProducer＆amp; JmsConsumer。现在我们想要获取当前队列的状态（如当前队列计数，等待计数，顺序，优先级）。这些所有细节都在JmsProducer中设置。

我们尝试使用CLI脚本和JBoss管理控制台获取这些详细信息。 Cli方法的工作原理如下所示。

使用的队列是HornetQ。

  "address" => [ 
     ("subsystem" => "messaging"), 
     ("hornetq-server" => "default"), 
     ("jms-queue" => "transmit_postprocessing") 
 ],
 "outcome" => "success",
 "result" => { 
     "consumer-count" => 1, 
     "dead-letter-address" => "jms.queue.DLQ", 
     "delivering-count" => 0, 
     "durable" => true, 
     "entries" => ["java:jboss/queue/transmit_postprocessing"], 
     "expiry-address" => "jms.queue.ExpiryQueue", 
     "message-count" => 0L, 
     "messages-added" => 4L, 
     "paused" => false, 
     "queue-address" => "jms.queue.transmit_postprocessing", 
     "scheduled-count" => 0L, 
     "selector" => undefined, 
     "temporary" => false 

 }

JmsProducer :(工作）

Context context = new InitialContext(); 
ConnectionFactory connectionFactory = (ConnectionFactory)context.lookup("java:/ConnectionFactory");
Connection connection = connectionFactory.createConnection(); 
Session jmsSession = connection.createSession(false, Session.AUTO_ACKNOWLEDGE); 
Destination destination = (Destination) context.lookup("java:jboss/queue/preprocessing"); 

MessageProducer messageProducer = jmsSession.createProducer(destination); 

ObjectMessage objectMessage = jmsSession.createObjectMessage(); 

         for (String key: payload.keySet()) { 
            String value = payload.get(key).toString();    
            objectMessage.setStringProperty(key, value); 
         }

有没有其他方法可以在JmsConsumer中获取队列详细信息？

我们以前的消费者代码现在不能正常工作（可能因为JBoss版本的chnage为7）。

我尝试了很多方法但是Enumeration总是为null（尽管会话/队列在JBoss上运行）

例如：

ConnectionFactory connectionFactory =  (ConnectionFactory)context.lookup("java:/ConnectionFactory");
Queue queue = (Queue)context.lookup("java:jboss/queue/preprocessing"); 
QueueBrowser browser = session.createBrowser(queue); 
ArrayList<QueueMessage> messages = new ArrayList<QueueMessage>(); 
Enumeration e = browser.getEnumeration();

任何可能的方法/方法/想法都会有用。提前谢谢。
