Question

我正在创建一条短信并将其放入activemq队列中，然后将其显示在日志中。现在我需要将此消息传递给cxf rs客户端以在参数中使用它。我正在使用蓝图来定义驼峰路由和cxf客户端。

        </setHeader>
        <to uri="cxfrs:bean:rsClient" />
    </route>

任何人都能帮帮我吗？感谢

两个路由都侦听 activemq：queue：LOG.ME 。 ActiveMQ中的队列将使用该消息，而任何其他队列都不会收到该消息。你需要做两件事之一：

将您的队列变为主题，以便两条路线都能收到该消息。 Topic vs Queue
安排您的路线，以便只有一条路线正在侦听 activemq：queue：LOG.ME 。

有两种方法可以实现这一目标：

将cxfrs：bean：rsClient调用转换为cxfrs：http://localhost:7171/customers/entry-point/register/nosJ并在最后附加参数。
关于此的文档不是很清楚，但您可以使用setHeader：

<setHeader headerName="CamelCxfRsQueryMap"> expression which returns a map </setHeader>

此表达式可以是<bean>，<groovy>嵌入式表达式等。
