TypeConversion例外：Apache的骆驼和CXF

问题描述

我试图与Apache集成骆驼CXF RESTful Web服务。我得到了以下异常，当我请求发送到我的web服务：

 产生的原因：org.apache.camel.NoTypeConversionAvailableException：没有可用的类型转换器从类型转换：org.apache.cxf.message.MessageContentsList到所需的类型：java.io. InputStream的值为[空]
    在org.apache.camel.impl.converter.BaseTypeConverterRegistry.mandatoryConvertTo(BaseTypeConverterRegistry.java:147)
    在org.apache.camel.impl.MessageSupport.getMandatoryBody（MessageSupport.java:100）
    ... 68更多
 

我贴我的配置XML的部分进行审核：

    ＆LT;参考豆=FooBar的/＆GT;

    ＆LT;属性名=dropRootElementVALUE =真/＆GT;
    ＆LT;属性名=supportUnwrappedVALUE =真/＆GT;

        ＆LT;骆驼：到URI =htt​​p://www.google.com/＆GT;
    ＆LT; /骆驼：路线＆GT;
＆LT; /骆驼：camelContext＆GT;
 

解决方案

解决..其实问题并没有当我的CXF服务器击中了所有的错误，它出来是当交换是在为部分...
我不得不往返之间增加一个处理器，并覆盖所有CamelHttpUri，CamelHttpMethod等....，使其工作。

 ＆LT; camelcxf：rsServer ID =rsServer地址=HTTP：//本地主机：端口/为MyApplication / REST / foobar的serviceClass =com.camel.example.FooBar/ ＆GT;＆LT;骆驼：camelContext ID =camelContext-1＆GT;＆LT;骆驼：路线＆GT;
＆LT;骆驼：从URI =cxfrs：豆：rsServer/＆GT;
＆LT;骆驼：过程REF =customInProcessor/＆GT;
＆LT;骆驼：到URI =htt​​p://www.google.com/＆GT;
 ＆LT; /骆驼：路线＆GT;
  ＆LT; /骆驼：camelContext＆GT;＆LT;豆的id =customInProcessor级=com.camel.MyInProcessor/＆GT;
 

I am trying to integrate CXF restful web services with Apache Camel. I am getting the following exception when I send a request to my web service:

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

I am pasting a section of my config xml for review:

<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>

解决方案

solved all the errors.. actually the problem was not when my cxf server was getting hit, it comes out to be when the exchange was in the "to" part...i had to add a processor in between from and to and override all the CamelHttpUri , CamelHttpMethod etc .... to make it work.

<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" />
