是否可以在远程代理上获取队列列表？ [英] Is it possible to get a list of queues on a remote broker?

问题描述

我正在试图找出如何获取远程代理上现有队列的列表。

I'm trying to figure out how to get a list of existing queues on a remote broker.

看起来我可以在创建队列时收听它们/通过添加一条建议消息（我还没有工作）来销毁，但我需要在启动时获得所有现有队列。

It looks like I can listen to queues as they are created/destroyed by adding an advisory message (which I don't yet have working) but I need to get all EXISTING queues on startup.

看起来我可以这样做使用getDestinationMap：

It looks like I can do this with getDestinationMap:

http://activemq.apache.org/maven/apidocs/org/apache/activemq/broker/region/Region.html#getDestinationMap（）

但这似乎只能从嵌入式和进程内代理调用。

But that seems like it can only be called from an embedded and in-process broker.

我的意思是......我愿意走那条路，但似乎更有意义的是为activemq设置正常的init / daemon，然后有一个远程进程像普通的JMS使用者一样连接到它。

I mean... I'm willing to go that route but it seems to make more sense to just have the normal init/daemon setup for activemq and then have a remote process connect to it like a normal JMS consumer.

这个文档似乎暗示它是可能的：

This documentation seems to imply that it's possible:

http://activemq.apache.org/how -can-i-see-what-destinations-are-used.html

但这是通过使用Region对象而且只有在你看来才有可能与activemq在同一个JVM中。

But that's by using a Region object and that only seems possible if you're in the same JVM as activemq.

推荐答案

    // Create a ConnectionFactory
ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:61616");

// Create a Connection
ActiveMQConnection connection = (ActiveMQConnection) connectionFactory.createConnection();


//Important point that was missed in the above answer
connection.start();

DestinationSource ds = connection.getDestinationSource();
Set<ActiveMQQueue> queues = ds.getQueues();

for(ActiveMQQueue queue : queues){
    try {
        System.out.println(queue.getQueueName());
    } catch (JMSException e) {
        e.printStackTrace();
    }
}
