我正在尝试测试 ActiveMQ 的队列持久性。
我有一个具有独特消费者的嵌入式 ActiveMQ 服务器。此嵌入式服务器从许多其他 JVM 应用程序接收 JMS 消息。
它工作正常，消费者应用程序接收通知。
所以我试图测试消息的持久性。我在消费者的 MessageListener 上放置了一个（远程）断点，以便我可以将许多消息排入队列并使 ActiveMQ 服务器崩溃。在服务器重新启动时，我希望所有排队的消息都能够被使用，而不是丢失。
然后我尝试了那个测试。我在第一条消息发送时进入了那个断点。但是对于我尝试发送的所有消息，我在生产者端得到以下堆栈跟踪：

我不明白为什么当我的消费者处于断点时我的生产者会被阻止。
我的经纪人 uri 是：mobilepush.activemq.broker.transport.connector.uri=tcp://0.0.0.0:61616
生产者通过 tcp 连接到代理。与代理共处一地的消费者通过vm://localhost.
我的配置很简单：
SERVER:
<!-- lets create an embedded ActiveMQ Broker -->
<amq:broker useJmx="false" persistent="true">
<amq:transportConnectors>
<amq:transportConnector uri="${mobilepush.activemq.broker.transport.connector.uri}" />
</amq:transportConnectors>
<amq:persistenceAdapter>
<amq:kahaPersistenceAdapter directory="${mobilepush.activemq.broker.queue.persistence.directory}" maxDataFileLength="100 Mb"/>
</amq:persistenceAdapter>
</amq:broker>
