駱駝休息，DSL請求返回404

遵循一個簡單的駱駝休息，DSL駱駝休息，DSL請求返回404

<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:camel="http://camel.apache.org/schema/spring" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd 
    http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd"> 


<camelContext xmlns="http://camel.apache.org/schema/spring"> 
    <restConfiguration bindingMode="auto" component="netty4-http" port="8080" host="localhost"/> 
    <rest path="/mycontext"> 
     <get uri="/foo"> 
      <to uri="direct:fooService"/> 
     </get> 
    </rest> 

    <route> 
     <from uri="direct:fooService"/> 
     <to uri="netty4-http:http://localhost:9773/services/foo"/> 
    </route> 

</camelContext>

當調用curl localhost:8080/mycontext/foo始終與下面的異常返回404：

org.apache.camel.component.netty4.http.NettyHttpOperationFailedException: Netty HTTP operation failed invoking http://localhost:9773/services/foo with statusCode: 404 
at org.apache.camel.component.netty4.http.NettyHttpHelper.populateNettyHttpOperationFailedException(NettyHttpHelper.java:160) 
at org.apache.camel.component.netty4.http.NettyHttpProducer$NettyHttpProducerCallback.done(NettyHttpProducer.java:111) 
at org.apache.camel.component.netty4.NettyProducer$NettyProducerCallback.done(NettyProducer.java:491) 
at org.apache.camel.component.netty4.handlers.ClientChannelHandler.channelRead0(ClientChannelHandler.java:189) 
at io.netty.channel.SimpleChannelInboundHandler.channelRead(SimpleChannelInboundHandler.java:105)

當我採取了數據包捕獲，我看到請求行不正確

GET http://localhost:9773/services/foo HTTP/1.1

，但是當我打的後端直接請求行是GET /services/foo HTTP/1.1

可能有人請幫我找出這個問題

您可以嘗試設置要在'Exchange.HTTP_URI'標頭內調用的URI，或嘗試將'＆bridgeEndpoint = true'設置爲屬性。作爲[記錄]（http://camel.apache.org/netty4-http.html）駱駝將調用實際的URI之前刪除任何組件屬性。不知道如果這能解決你的問題 –

不幸的是，問題仍然存在:( – user392919

您的代碼是不正確的。

<to uri="netty4-http:http://localhost:9773/services/foo"/>

文檔中提到的netty組件處理TCP/UDP通信，而不是HTTP。在任何情況下，URI也是錯誤的。

比如，你可以寫TCP：

<from uri="netty4:tcp://localhost:5022?textline=true&amp;sync=true&amp;workerPool=#sharedPool&amp;usingExecutorService=false"/> 
    <to uri="log:result"/>

看http://camel.apache.org/netty4.html對這種解釋。如果您確實想要進行HTTP通信，請使用jetty或Restlet。
