Question

我正在尝试在camel中创建一个简单的路由，从rest uri接收消息并将消息存储在缓存中，我已经完成了以下操作

我的路线如下

<camel:endpoint id="fooCache1" uri="cache:TestCache1"/>  <camel:from uri="cxfrs://bean://rsServer" />
        <camel:to uri="log:output?showAll=true" />
        <camel:to uri="bean:payProcessor" />
        <camel:to uri="direct:start" />
        </camel:route>
               <camel:route>
    <camel:from uri="direct:start" />   
    <camel:setHeader headerName="CamelCacheOperation">
            <camel:constant>CamelCacheAdd</camel:constant>
        </camel:setHeader>
        <camel:setHeader headerName="CamelCacheKey">
            <camel:constant>myCache</camel:constant>
        </camel:setHeader>
     <camel:to  ref="fooCache1"/>
<camel:to uri="log:output?showAll=true" />
     </camel:route>

当试图通过mvn camel在驼峰上运行它时：运行我得到以下错误

有人可以让我知道我错在哪里以及为什么没有创建缓存bean。我对这个错误感到茫然。提前谢谢。

Answer 1

检查camel-spring和camel-core组件的版本，在您的情况下似乎存在兼容性问题。使用两个库的相同版本。
