從Apache Camel Blueprint調用REST服務

我想調用返回JSON的外部REST服務，REST本身具有基本身份驗證（我不知道如何發送基本身份驗證），我已閱讀了一些教程還有CXFRS組件導致我這個blueprint.xml。從Apache Camel Blueprint調用REST服務

<?xml version="1.0" encoding="UTF-8"?> 

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xmlns:cxf="http://camel.apache.org/schema/cxf" 
     xmlns:jaxrs="http://cxf.apache.org/jaxrs" 
     xsi:schemaLocation=" 
     http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd 
     http://camel.apache.org/schema/cxf http://camel.apache.org/schema/cxf/camel-cxf.xsd 
     http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.xsd"> 

    <bean id="jsonProvider" class="org.apache.cxf.jaxrs.provider.json.JSONProvider"/> 

    <cxf:rsClient id="rsClient" address="http://localhost/test.php"> 
    <cxf:providers> 
     <ref bean="jsonProvider"/> 
    </cxf:providers> 
    </cxf:rsClient> 

    <camelContext xmlns="http://camel.apache.org/schema/blueprint"> 
    <propertyPlaceholder location="classpath:sql.properties" id="placeholder"/> 

    <route> 
     <from uri="cxfrs://bean://rsClient"/> 
     <log message="${body}"/> 
    </route> 

    </camelContext> 

</blueprint>

如果它甚至相關的，我使用JBoss Developer Studio中開發和使用右鍵點擊blueprint.xml -> Run As -> Local Camel Context (without tests)測試這裏是從輸出。

除了我得到了錯誤，究竟我可以打電話或使用藍圖從Apache的駱駝調用REST服務，並得到返回的JSON？

我認爲使用其餘dsl來簡單休息操作要容易得多。看到這裏： http://camel.apache.org/rest-dsl.html。另外，你使用紅帽版本的原因是什麼？ –

Rest DSL實際上只是爲了定義或創建REST服務器服務？不消耗或調用外部REST服務？因爲我工作的公司把RedHat JBoss作爲我們集成的要求。哦，順便說一下，當看到休息DSL有'駱駝碼頭'，我可以使用它嗎？ – Adakbar

我解決了這個問題，但使用Camel HTTP組件，我可以輕鬆調用REST API並獲取JSON響應，但首先我必須先設置一些標頭。

<route> 
    <from uri="timer:foo?repeatCount=1"/> 

    <setHeader headerName="Exchange.HTTP_METHOD"> 
    <constant>GET</constant> 
    </setHeader> 

    <to uri="http:localhost/api/test"/> 
    <log message="${body}"/> 
</route>
