Question

我正在使用Apache camel在ActiveMQ和camel HTTP端点之间进行路由。路由的定义方式是将数据从camel-cxf Web服务获取到ActiveMQ，并将这些数据发布到作为HTTP端点的tomcat，然后一旦http uri命中，骆驼就会从tomcat服务器获得响应。

我们能否仅在成功路由后确认骆驼队列，我的意思是在完成 LOG_log_4 过程之后确认AMQ？如果可能的话，即使http链接断开，我也可以进行此路由而不会在队列中丢失任何数据。

我找到了此链接JMS ACKNOWLEDGE_MODE。如果我需要使用确认模式CLIENT_ACKNOWLEDGE，那么我是否需要在tomcat网站应用站点上编写消费者服务，以确认已成功接收msg。

我将Acknowledgemodename用作AUTO_ACKNOWLEDGE。

详细路线图如下：-

经纪人一经消费，便立即收到确认。即就您而言，<camel:from id="_from2" uri="amq:queue:queue1x?concurrentConsumers=2"/>

您的要求尚不明确，但是，如果您需要对队列实施请求答复，则可以将replyTo参数设置为排队，并将从tomcat收到的响应消息推送到该ReplyTo队列。或者，让我知道确切的要求。
