Question

我正在尝试在启动ActiveMQ时设置主题。我们将拥有Durable订阅者，但他们尚未推出。

Startup Config说要添加：

<destinations>
  <queue physicalName="FOO.BAR" />
  <topic physicalName="SOME.TOPIC" />
</destinations>

我已将此添加到activemq.xml但没有运气。在ActiveMQ启动时没有创建主题。我们正在运行5.7。

想法？

编辑：

我正在尝试在ActiveMQ的启动时设置主题。重新启动（或关闭并启动）ActiveMQ时，会删除主题，因为它们位于内存中。我想在XML配置中添加一个主题，以便在AMQ启动时即时创建。通过这种方式，我们的ESB可以直接访问它并开始工作。 ESB将是Durable订户，但尚未订购。仍在实施。文档说在XML配置中添加到上面的行。但我没有运气。启动时不会创建主题。

所以我会把它们添加到任何地方？

Answer 1

我刚刚将它们放入一个普通的5.7 AMQ安装（在MacOS上），我通过Web控制台看到了队列和主题......

你应该再次尝试使用干净安装的AMQ来尝试缩小问题范围

Answer 2

我自己的解决方案有效。虽然在我们的Linux环境中我们有多个实例。一个在/ user / share下，一个在/ home / activemq /

下

所以当我编辑corret文件时它就起作用了。

感谢您的努力。

Answer 3

将目的地放在<destinations>标签内，如

<destinations>
   <queue physicalName="FOO.BAR" />
   <topic physicalName="SOME.TOPIC" />
</destinations>

内
