Question

我正在尝试使用Spring-Integration JMS的示例项目进行JMS集成，我已经成功完成了这项工作。我怎么会有一个稍微不同的要求。我需要使用Publish Subscribe模式从1个JMS代理监听，我需要将相同的侦听JMS消息发送到另一个Kafak Queue /或其他队列。我正在努力配置，截至目前我只配置了请求和响应队列。这是配置。请帮忙。

Answer 1

看起来你没有足够的理论知识，所以你应该去关于Spring Integration的文档和书籍。你还没有感觉到MessageChannel还有什么。

<jms:message-driven-channel-adapter id="jmsIn"
        destination="requestQueue"
        channel="jmsInChannel" />

表示：侦听requestQueue目标并将Spring Integration消息发送到jmsInChannel。

如果您只想将该消息发送到另一个JMS目的地，您应该执行以下操作：

<jms:outbound-channel-adapter id="jmsout" channel="jmsInChannel" destination="replyQueue"/>

请确保jmsInChannel没有其他订阅者，因为它是DirectChannel。

根据您当前的配置，您有其他订阅者<bridge>。在这种情况下，Round-Robin平衡器适用于jmsInChannel，第一个消息将发送给第一个订阅者，而第二个消息将发送到第二个订阅者，依此类推。

如果您希望两个订阅者都接受该消息，则应将jmsInChannel更改为<publish-subscribe-channel>。

您可以从文档中找到更多信息。
