使用RabbitMQ和Apache Camel获取AMQP消息的错误路由密钥

我很难找到骆驼路线的问题。从我所读到的，似乎这可能是我的路由密钥头信息搞砸了，但我不知道如何解决这个问题。另外，这是一个JavaOSGi项目，如果这很重要的话，但是所有的Camel文件目前都是用XML实现的。感谢您的帮助

以下是我想做的：

<!-- The first route creates an object with some info in it and drop it on a rabbitmq 
exchange called message.added -->
<route id="directIn">
    <from uri="direct:in" />
    <bean ref="connector" method="handleIncoming" />
    <marshal id="marshal-one" ref="firstObject" />
    <to uri="rabbitmq://localhost:5672/me.ex?exchangeType=topic&amp;durable=false&amp;autoDelete=true&amp;routingKey=message.added" />
</route>

<!-- This route listens to message.added, processes the data, creates a new object, and 
drops it on a different rabbitmq exchange called message.rest -->
<route id="addedOne">
    <from uri="rabbitmq://localhost:5672/me.ex?exchangeType=topic&amp;durable=false&amp;autoDelete=true&amp;routingKey=message.added" />
    <unmarshal id="unmarshal-one" ref="firstObject" />
    <bean ref="connector" method="processAndConvert" />
    <marshal id="marshal-out" ref="secondObject" />
    <to uri="rabbitmq://localhost:5672/me.ex?exchangeType=topic&amp;durable=false&amp;autoDelete=true&amp;routingKey=message.rest" />
</route>

似乎“secondObject”在某个点上正在进入“message.added”交换，并被“addedTwo”路由拾取，该路由试图将其封送到“firstObject”中。但是我没有明确告诉它在代码中的任何地方都要这样做-有什么想法吗？

在RabbitMQ Camel组件中，

routingKey

端点选项只适用于消费者（

）

生产者必须将其路由密钥明确设置为

之前的消息头。您的

addedOne

路线应如下所示：

<route id="addedOne">
    <from uri="rabbitmq://localhost:5672/me.ex?exchangeType=topic&amp;durable=false&amp;autoDelete=true&amp;routingKey=message.added" />
    <unmarshal id="unmarshal-one" ref="firstObject" />
    <bean ref="connector" method="processAndConvert" />
    <marshal id="marshal-out" ref="secondObject" />
    <setHeader headerName="rabbitmq.ROUTING_KEY">
        <constant>message.rest</constant>
    </setHeader>
    <to uri="rabbitmq://localhost:5672/me.ex?exchangeType=topic&amp;durable=false&amp;autoDelete=true" />
</route>

message.rest
