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类似于 XML 的标头？
下面的 xml 是由 SOAP UI 自动生成的请求，并且在给定正确的用户名/密码的情况下工作正常。

<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 添加标题部分。我已经使用 WSDL 的 CXF 自动生成了一段代码(见下文(，并检查了各种文章，但代码仍然不起作用。我假设发送的请求不正确或没有标头。

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 服务的请求中添加标头。 我需要做的就是在我的Maven CXF插件构建中添加下面的额外代码。

<extendedSoapHeaders>true</extendedSoapHeaders>

上面的额外行仅在 wsdl 中显式声明 soap 标头部分时才有效，在我的情况下。

<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，如下所示

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");
}

一切正常，标头现在插入到发送到 Web 服务的 XML 请求中。
