如何测试此故障转移activemq队列案例



我得到了我的activemq配置文件,我的mule使用"jms:activemq连接器"进行流,如下所示:

<jms:activemq-connector name="Active_MQ" specification="1.1" brokerURL="failover://(tcp://localhost:61616,tcp://localhost:61617)?randomize=false" validateConnections="false" maxRedelivery="1" doc:name="Active MQ"/>

这是我的activemq.xml

</beans>

看起来那些url的故障转移"有效"。

问题,我应该如何测试故障转移???有什么建议吗?这是我第一次实现这个功能。

谢谢。

根据请求:

实际上,我在单独的cmd提示符下运行了两个不同的activemq,在每个activemq文件夹中配置了conf文件。仅此而已。

它通过执行"故障切换://(tcp://localhost:61616,tcp://localhost:61617)"在骡子一侧。

关闭61616后,所有条目都将转到第二个代理,即61617。所以效果很好。
