在Spring-WS中将子元素添加到自定义SOAP标头中

Question

我正在使用Spring-WS调用SOAP Web服务.有问题的webservice要求我在SOAP头中传递一些信息,如下所示:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Header>
      <CustomHeaderElement>
         <clientID>xyz</clientID>
         <wsdlVersion>1.0</wsdlVersion>
         <serviceType>ExampleService_v1</serviceType>
      </CustomHeaderElement>
   </soapenv:Header>
   <soapenv:Body>
   ...
   </soapenv:Body>
</soapenv:Envelope>

我已经弄清楚如何使用顶级CustomHeaderElement,但我没有在Spring-WS API中看到任何允许我添加子元素的内容.这是我到目前为止:

WebServiceTemplate template = ...;

template.marshalSendAndReceive(request, new WebServiceMessageCallback(){
    public void doWithMessage(WebServiceMessage message) throws IOException, TransformerException{
        SoapMessage soapMessage = (SoapMessage)message;
        SoapHeader soapHeader = soapMessage.getSoapHeader();
        QName qName = new QName("CustomHeaderElement");
        SOAPHeaderElement headerElement = soapHeader.addHeaderElement(qName);
        //would like to do something like headerElement.addChild(clientIdNode);
    }
});

问题是headerElement似乎没有暴露任何实际添加子的方法.我知道我可以添加一个属性,但这不是我需要的服务调用.有谁知道如何将必要的子元素添加到我的自定义标题？

我遇到了同样的问题,这是我的解决方案,但它只适用于复杂的简单元素:

template.marshalSendAndReceive(request, new WebServiceMessageCallback(){
    public void doWithMessage(WebServiceMessage message) throws IOException, TransformerException{
        SaajSoapMessage soapMessage = (SaajSoapMessage) message;
        SoapHeaderElement messageId =  soapMessage.getSoapHeader().addHeaderElement(new QName("http://www.w3.org/2005/08/addressing", "MessageID", "wsa"));
        messageId.setText("urn:abcdef1234");
    }
});

它产生以下XML:

<SOAP-ENV:Header>
  <wsa:MessageID>urn:abcdef1234</wsa:MessageID>
</SOAP-ENV:Header>

BTW javax.xml.soap.SOAPMessage也可以工作,请看这里:http://docs.oracle.com/javaee/5/tutorial/doc/bnbhr.html#bnbia

我对这个解决方案并不满意，但事实证明您实际上可以将消息转换为 SOAPMessage，这样您就可以完全访问所有 SAAJ api。从那里您可以在标题中构建您想要的任何元素。
