我有一个要求，我想每 5 分钟轮询一次 JMS 队列并使用 jms 队列中的所有消息。我正在尝试在 mule 中执行以下操作：
<jms:inbound-endpoint queue="jmsqueue" exchange-pattern="one-way" >
<properties>
<spring:entry key="pollingFrequency" value="100000" />
</properties>
</jms:inbound-endpoint>
上面的代码正在工作，但它忽略了 pollingFrequency 属性。
有人可以帮我如何在 Mule 中设置 JMS 队列的轮询频率吗？
上述问题已解决。但是通过我的修复，我遇到了以下异常：
