这是我在activeMQ日志中获得的异常。场景：我有10个消费者，我在消费者正在收听的目标队列中有100条消息。消费者正在获取大约10-20条消息的消息，但最终会因上述异常而停止从队列中获取消息。我的理解是，只有在回复确认时才会给消费者一个新的消息（如果我正确的话）。 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，让我感谢自己回答这个问题。显然，当通过httpclient连接到数据库时，消费者遇到了一些异常，这会杀死所有的消费者线程。无论如何，任何有这个问题没有任何例外的人都可以尝试解决， 1.增加activeMQ config中的内存限制＆＃34; conf / activemq.xml＆＃34; 2.尝试将确认方法更改为＆＃34;交易＆＃34;或在消息本身中确认 message.acknowledge（）;

ActiveMQ抛出不匹配的确认异常
