Question

鉴于我在IBM WebSphere AS 8.5.5.9中运行应用程序，通过JMS连接到IBM WebSphere MQ 7.0（通过JNDI解析），使用spring-integraion-jms（4.2.5）inbound-gateway配置如下： / p>

    <int-jms:inbound-gateway id="requestGateway"
                         connection-factory="jndiConnectionFactory"

                         request-destination="jndiQueueInput"
                         request-channel="channel.request.message"

                         reply-channel="channel.response.message"
                         default-reply-destination="jndiQueueOutput"

                         error-channel="errorChannel"/>

已处理入站邮件，状态回复邮件到达频道channel.response.message。当入站消息在异常引发之后具有不正确的jms_replyTo标头（即不存在的队列）时，忽略错误通道设置（正确处理集成流期间的任何其他异常）：

然后消息被回滚，并重新传递，从而产生无限循环。除了Handling poison messages in WebSphere MQ classes for JMS之外，是否有针对此问题的解决方法或最佳做法？

Answer 1

错误通道旨在捕获来自网关的下游流中的异常，回复的发送当前不在错误通道处理的范围内。

去年我们在将消息发送到下游流之前将范围扩展到包括消息转换，但是回复处理仍在该范围之外。

我们可以考虑添加它但是现在，唯一的解决方法是使用有害消息的东西。或者，如果您知道应用程序中哪些replyTo队列有效，您可以检查jms_replyTo标头并从您的流中抛出异常。

当replyTo设置为不存在的队列时，无限JMS消息重新传递循环
