我在 Active MQ 文档中读到,当用于创建临时队列的连接关闭时,临时队列会被代理删除。
我正在使用 Apache NMS v1.5.0 和 Active MQ 5.1.3,即使连接超出范围,临时队列也始终存在。
我有一个客户端/服务器方案,客户端创建一个临时队列并创建一条消息,在消息的 ReplyTo 属性中指定临时队列。服务器组件然后读取消息并开始将消息发送到回复队列。
不幸的是,当客户端关闭它的连接时,它创建的临时队列不会被删除。
下面的代码片段应该说明我的意思。
我创建一个连接,并使用该连接创建一个临时队列。我关闭连接并创建第二个。我应该无法使用第二个连接创建的会话在临时队列上生成和使用消息,但我可以。
有人可以告诉我我是否在这里做错了什么。如何让 Active MQ 删除临时队列。
非常感谢任何帮助。
