使用 CXF 在 Web 服务请求上添加标头

Question

如何在 Web 服务客户端请求上添加如下 XML 所示的标头？
下面的 xml 是由 SOAP UI 自动生成的请求，只要提供正确的用户名/密码，它就可以正常工作。

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:dof="http://dof.ad.com">
   <soapenv:Header>
      <dof:UserCredentials>
         <!--Optional:-->
         <dof:userName></dof:userName>
         <!--Optional:-->
         <dof:password></dof:password>
      </dof:UserCredentials>
   </soapenv:Header>
   <soapenv:Body>
      <dof:CheckService/>
   </soapenv:Body>
</soapenv:Envelope>

我想知道如何使用 apache CXF 添加标头部分。我已经使用 WSDL 中的 CXF 自动生成了代码（见下文）并检查了各种文章，但代码仍然无法正常工作。我假设发送的请求不正确或者没有标头。

public static void checkServiceMan() {
    String address = "https://WSDL_URL";

    JaxWsProxyFactoryBean jaxWsProxy = new JaxWsProxyFactoryBean();
    jaxWsProxy.setServiceClass(DOFairservice.class);
    jaxWsProxy.setAddress(address);

    DOFairservice serviceClient = (DOFairservice) jaxWsProxy.create();

    ObjectFactory factory = new ObjectFactory();
    UserCredentials uc = factory.createUserCredentials();
    uc.setUserName("username");
    uc.setPassword("password");

    List<Header> headerList = new ArrayList<Header>();
    try {

        Header testCredentialsHeader = new Header(new QName("http://DOF", "DOFairservice")
                ,uc
                ,new JAXBDataBinding(UserCredentials.class));

        headerList.add(testCredentialsHeader);

    } catch (JAXBException e) {

        e.printStackTrace();
    }
    ((BindingProvider) serviceClient).getResponseContext().put(Header.HEADER_LIST, headerList);

    Client client = ClientProxy.getClient(serviceClient);
    HTTPConduit conduit = (HTTPConduit) client.getConduit();
    HTTPClientPolicy policy = conduit.getClient();
    policy.setReceiveTimeout(10000);

    String resp = serviceClient.checkService(); **<--- ERROR HERE**
    System.out.println("Response from Customs Web Service: "+ resp);

    System.out.println("Web Service Header Test Done");
}

错误信息

我找到了一个简单的解决方案，可以在发送到 Web 服务的请求上添加标头。我所需要做的只是在我的 Maven CXF 插件构建中添加下面的额外代码。

<extendedSoapHeaders>true</extendedSoapHeaders>

仅当在 wsdl 中显式声明了肥皂头部分（在我的情况下）时，上面的额外行才有效。

<wsdl:input>
<soap:body use="literal"/>
<soap:header message="tns:CheckUserCredentials" part="UserCredentials" use="literal"/>
</wsdl:input>

我重新生成了源代码并进行了修改，请参见下文

public static void checkServiceMan() {
    String address = "https://WSDL_URL";

    JaxWsProxyFactoryBean jaxWsProxy = new JaxWsProxyFactoryBean();
    jaxWsProxy.setServiceClass(DOFairservice.class);
    jaxWsProxy.setAddress(address);

    DOFairservice serviceClient = (DOFairservice) jaxWsProxy.create();

    ObjectFactory factory = new ObjectFactory();
    UserCredentials uc = factory.createUserCredentials();
    uc.setUserName("username");
    uc.setPassword("password");

    String resp = serviceClient.checkService(uc); **<--- New Argument Here**
    System.out.println("Response from Customs Web Service: "+ resp);

    System.out.println("Web Service Header Test Done");
}

一切工作正常，标头现在已插入到发送到 Web 服务的 XML 请求中。
