Apache Camel 路由性能

Question

我正在使用 Camel Restlet 进行一般路由，响应时间为 300 毫秒，我可以做任何设置来减少响应时间。

我的路由配置

 <route id="retriveEntry">
                <from uri="restlet:/user/{cachename}/{userId}?restletMethod=GET"/>
                <setHeader headerName="Content-Type">
                  <constant>application/xml</constant>
                </setHeader>
                <!-- <process ref="requestTimeProc"/> -->
                <to uri="restlet:http://hostname:8180/rest/{cachename}/{userId}?restletMethod=GET"/>
                <!-- <process ref="responseTimeProc"/> -->
            </route>

Response time By hitting the backend URL directly is :40 ms http://hostname:8180/rest/{cachename}/{userId}

我还在骆驼日志中看到了这些警告，不知道为什么：

WARNING: Addition of the standard header "Content-Length" is not allowed. Please use the equivalent property in the Restlet API.

Answer 1

由于您只是将请求路由到后端服务，因此您不需要使用 camel-rest 来完成此类工作。您可以使用 camel-jetty 和 camel-http 来定义这样的路线

<route>
    <from uri="jetty:xxx"/>
    <to uri="http://xxx"/>
</route>

对于警告消息，它应该在CAMEL-6590中解析
