可以以某种方式查看AMQ主题的内容吗? [英] Can the contents of an AMQ topic be viewed somehow?

问题描述

我正在尝试使用activemq-admin查看主题的内容.

I'm trying to view the contents of a topic using activemq-admin.

这是我正在尝试的:

./activemq-admin browse --amqurl tcp://localhost:61616 my.topic

这是我得到的输出:

Java Runtime: Sun Microsystems Inc. 1.6.0_24 /usr/lib/jvm/java-6-sun-1.6.0.24/jre
Heap sizes: current=62848k  free=62190k  max=932096k
JVM args: -Dactivemq.classpath=/home/pc/dev/apache-activemq-5.3.1/conf; -Dactivemq.home=/home/pc/dev/apache-activemq-5.3.1 -Dactivemq.base=/home/pc/dev/apache-activemq-5.3.1
ACTIVEMQ_HOME: /home/pc/dev/apache-activemq-5.3.1
ACTIVEMQ_BASE: /home/pc/dev/apache-activemq-5.3.1

这不是我想要的.我想以某种方式查看队列中的消息.有可能吗?

Which is not what I want. I want to see the messages in the queue in raw form somehow. Is that possible ?

谢谢

推荐答案

由于主题的性质，您无法浏览主题的内容.发送消息，并且如果有任何订阅者，每个订阅者都会在该时间点接收到一条消息.消息通常不保留(这里有一些不相关的例外).

You cannot browse the contents of topics due to the nature of what a topic is. Messages are sent in, and if there are any subscribers, each receives a message at that point in time. Messages are generally not retained (with some exceptions that aren't relevant here).

但是，有时出于调试目的，查看发送到主题的消息很有用.最简单的方法是设置虚拟目的地，该副本会复制发送的每条消息将该主题排入队列.

However, sometimes for debugging purposes it's useful to see messages that were sent to a topic. The easiest way to do so is to set up a virtual destination, that copies each message sent to the topic into a queue.

<destinationInterceptors>
    <virtualDestinationInterceptor>
        <virtualDestinations>
            <compositeTopic name="events" forwardOnly="false">
                <forwardTo>
                    <queue physicalName="events.thatHaveHappened" />
                </forwardTo>
            </compositeTopic>
        </virtualDestinations>
    </virtualDestinationInterceptor>
</destinationInterceptors>

然后您可以通过JMX或Web控制台浏览队列.

You can then browse the queue via JMX or the web console.
