Question

在我们尝试将spring-jms-4.0.2升级到4.3.8并且activemq保持在5.13.0之后，我们遇到了一个奇怪的问题。

我们目睹的是在spring-jms或activemq方面的连续循环，并且在我们在Tomcat中启动应用程序后，CPU始终固定在20-40左右的范围内。

如果我们回去并且只是用4.0.2版本替换lib中的spring-jms 4.3.8，那么一切都在开始后正常运行。

并发使用者为2，缓存级别设置为3，用于＆＃34; DefaultMessageListenerContainer＆＃34;在春天。

以下是几个指标：

我们启用了springframework和activemq的调试日志记录，我们在spring log中看到的只有3行，而不管spring jms jar版本。

2017-06-22T12:09:02,928 DEBUG [org.springframework.jms.listener.DefaultMessageListenerContainer] Established shared JMS Connection
2017-06-22T12:09:02,930 DEBUG [org.springframework.jms.listener.DefaultMessageListenerContainer] Resumed paused task: org.springframework.jms.listener.DefaultMessageListenerContainer$AsyncMessageListenerInvoker@bd71008

但这是activemq日志之间的区别

当我们使用spring-jms-4.0.2时

如果我们查看两个activemq日志之间的区别，

它显示队列订阅行正在打印一次或两次，然后在30秒的间隔后，到期时间开始并且循环继续

但是在第二个日志中，到期时间从未开始，并且每隔ms打印一次队列订阅行，并且日志会在几分钟内进入GB，因此会出现某种循环。

我们正在尝试对此进行调试，但如果有人有任何想法或建议，请通过。

感谢。

Answer 1

发现问题，升级后的4.3.8版本现在有0为receivetimeout而不是早于-1等待它获取我们曾经使用的新消息，以及为什么它试图从代理获取消息（activemq））在循环中并用那些导致CPU持续使用的调用轰炸它。

来自JmsDestinationAccessor类的代码片段。

protected Message receiveFromConsumer(MessageConsumer consumer, long timeout) throws JMSException {
    if (timeout > 0) {
        return consumer.receive(timeout);
    }
    else if (timeout < 0) {
        return consumer.receiveNoWait();
    }
    else {
        return consumer.receive();
    }
}

Spring jms 4.3.8 vs 4.0.2 with activemq 5.13.0 issue
