CXF通过拦截器修改请求报文

最近一位做Siebel的同事需要通过Web Service接口调用另外一个系统，对方的Web Service使用的是CXF框架，并提供了WSDL文件。

Siebel通过WSDL生成请求报文时报错，而直接通过SoapUI导入WSDL测试是OK的。通过抓取报文发现，两者生成的报文namespace有所不同，Siebel生成的namespace放在节点上，SoapUI生成的namespace放在头上，具体如下：

Siebel生成的报文：

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <SOAP-ENV:Body>
      <handleCallCenterWarningInfo xmlns="http://service.webservice.kora.com/">
         <arg0>
            <handleDepartment/>
            <handleResult/>
            <handleStatus>1</handleStatus>
            <handleTime/>
            <realWarningCaseId/>
            <rescueOrderNumber>121212121</rescueOrderNumber>
         </arg0>
      </handleCallCenterWarningInfo>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Siebel调用时报错信息如下：

Unmarshalling Error: unexpected element (uri:"http://service.webservice.kora.com/", local:"arg0"). Expected elements are <{}arg0>

SoapUI生成的报文：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://server.webservice.mycompany.com/">
   <soapenv:Header/>
   <soapenv:Body>
      <ser:haha>
         <arg0>
            <handleDepartment>1</handleDepartment>
            <handleResult>2</handleResult>
            <handleStatus>3</handleStatus>
            <handleTime>4</handleTime>
            <realWarningCaseId>5</realWarningCaseId>
            <rescueOrderNumber>6</rescueOrderNumber>
         </arg0>
      </ser:haha>
   </soapenv:Body>
</soapenv:Envelope>

针对报文格式问题，准备两种尝试方式：

1、拦截请求报文，把报文修改成符合WS命名空间的结构。

2、通过CXF框架的设置，设成不校验命名空间。（此方式没有技术参考，凭空想象的。后经测试验证也没有发现该配置选项，具体的WS规范以及CXF实现后续需要更深一步的查阅文档以及源码）

后经测试验证，最终选择了方式1解决，具体调整步骤如下：

1、在WS配置文件中增加红色区域内容。

<jaxws:endpoint implementor="com.kora.webservice.service.CallCenterServiceImplPortImpl" address="/callCenterService" >

<jaxws:inInterceptors>

<constructor-arg><value>receive</value></constructor-arg>

</bean>

</jaxws:inInterceptors>

</jaxws:endpoint>

2、增加一个拦截类CallCenterServiceImplPortImpl修改报文：
