在经过maxInactivityDuration设置后，ActiveMQ InactivityMonitor未关闭

我在我的应用程序中实现了ActiveMQ。我有一个用例，当远程侦听队列中没有消息时，我需要关闭activeMQ连接，当有消息时我必须重新打开连接。我知道设置maxInactivityDuration = 30000不会帮助我实现这个用例，但至少它在经过30秒超时设置后没有关闭连接。请告诉我这方面有什么问题，也让我知道如何实现我的用例。谢谢你的解决方案。

根据您的代码，您已经为连接注册了一个侦听器，因此它不会处于空闲状态，因此不会被关闭。

但是如果你想强行关闭连接，那么你可能需要为你的连接设置maxTimeout。
