java - 类型转换异常: Apache Camel and CXF

Question

我正在尝试将 CXF Restful Web 服务与 Apache Camel 集成。当我向网络服务发送请求时，出现以下异常:

Caused by: org.apache.camel.NoTypeConversionAvailableException: No type converter available to convert from type: org.apache.cxf.message.MessageContentsList to the required type: java.io.InputStream with value [null]
    at org.apache.camel.impl.converter.BaseTypeConverterRegistry.mandatoryConvertTo(BaseTypeConverterRegistry.java:147)
    at org.apache.camel.impl.MessageSupport.getMandatoryBody(MessageSupport.java:100)
    ... 68 more

我正在粘贴配置 xml 的一部分以供审核:

<jaxrs:server id="restContainer" address="/" staticSubresourceResolution="true">

<jaxrs:serviceBeans>
    <ref bean="FooBar"/>
</jaxrs:serviceBeans>

<jaxrs:providers>
    <bean class="org.apache.cxf.jaxrs.provider.JSONProvider">
    <property name="dropRootElement" value="true"/>
    <property name="supportUnwrapped" value="true"/>
</jaxrs:providers>

<camelcxf:rsServer id="rsServer" address="http://localhost:port/MyApplication/rest/foobar" serviceClass="com.camel.example.FooBar"/>

<camel:camelContext id="camelContext-1">
    <camel:route>
        <camel:from uri="cxfrs:bean:rsServer"/>
        <camel:to uri="http://www.google.com"/>
    </camel:route>
</camel:camelContext> 

Answer 1

解决了所有错误..实际上问题不是当我的cxf服务器受到攻击时，而是当交换处于“to”部分时......我必须在 from 和 to 之间添加一个处理器并覆盖所有 CamelHttpUri 、 CamelHttpMethod 等......才能使其工作。

<camelcxf:rsServer id="rsServer" address="http://localhost:port/MyApplication/rest/foobar serviceClass="com.camel.example.FooBar" />  <camel:camelContext id="camelContext-1">  <camel:route>  
<camel:from uri="cxfrs:bean:rsServer" />  
<camel:process ref="customInProcessor" />
<camel:to uri="http://www.google.com" /> 
 </camel:route>
  </camel:camelContext> 

<bean id="customInProcessor" class="com.camel.MyInProcessor" />
