这是我在 activeMQ 日志中得到的异常。场景:我有 10 个消费者，消费者正在监听的目标队列中有 100 条消息。消费者正在获取大约 10-20 条消息的消息，但最终停止从队列中获取消息并出现上述异常。我的理解是，消费者只会在返回确认时收到一条新消息(如果我是对的)。JMS 容器:

<jms:listener-container container-type="default" connection-factory="jmsConsumerConnectionFactory"
acknowledge="auto">
<jms:listener destination="DATA.DESTINATION" ref="jmsMessageListener" concurrency="10-15" method="onMessage"/>
</jms:listener-container>

非常感谢任何帮助，谢谢!

好吧，让我感谢我自己回答这个问题。显然，消费者在通过 httpclient 连接到数据库时遇到了一些异常，这会杀死所有消费者线程。无论如何，任何遇到此问题且没有任何异常(exception)情况的人都可以尝试通过以下方式解决，1.增加activeMQ配置“conf/activemq.xml”中的内存限制2.尝试将确认方法更改为“已交易”或在消息本身中确认消息.acknowledge();
