Question

我可以使用收件人列表路由器从HTTP入站端点路由到2个JMS队列吗？我的目标是将消息从HTTP入站端点路由到2个jms队列，即订单和项目队列。我想使用收件人列表路由器来做到这一点。我不想使用pub子通道解决方案。

说实话，你的问题并不清楚。

<recipient-list-router>完全确实。

您指定了多个<recipient>，并且每个{}都将接收相同的消息。如果它是JMS适配器或其他任何东西都无关紧要。

阅读您的问题即使只使用<publish-subscribe-channel>，您也可以这样做：您需要使用相同的<int-jms:outbound-channel-adapter>引用指定多个channel。

你真的必须从日志和错误配置开始......

所以，让我们再来看看StackTrace吧！

org.springframework.beans.factory.BeanCreationException: Error creating bean wit h name 'org.springframework.integration.handler.MessageHandlerChain#0': Invocati on of init method failed; nested exception is java.lang.IllegalArgumentException : All handlers except for the last one in the chain must implement the MessagePr oducer interface. Object of class [org.springframework.integration.router.RecipientListRouter] must be an instance of interface org.springframework.integration. core.MessageProducer

因此，它表示您的RecipientListRouter必须MessageProducer才能将邮件转移到<chain>中的下一个处理程序，或者它必须是<chain>中的最后一个组件}。

根据Router架构，它不是AbstractReplyProducingMessageHandler，例如ServiceActivatingHandler。

在路由器配置上有多种选择，合乎逻辑的是我们没有正常的回复行为。

因此，为了完成您的任务，您应该再将一个处理程序移动到<recipient-list-router>映射！
