java - Apache CXF 3.1.6 Web 服务客户端 - NTLM 身份验证

Question

我正在尝试连接到通过 NTLM 进行身份验证的服务。我有使用 Maven cxf 插件 wsdl2java 生成的客户端。我遇到了一个异常(exception):org.apache.cxf.ws.policy.PolicyException:没有一个策略替代方案可以得到满足。也许还有另一种方法可以进行此身份验证。

public class UFENTLM1Test {

public static void main(String[] args) throws NoSuchFieldException, IllegalAccessException, ClassNotFoundException, InstantiationException {
    System.out.println("UFE SERVICE TEST (NTLM No1 WRAPPER)");
    System.out.println("PARAMS: " + args[1] + " " + args[2] + " ");
    System.out.println("START");

    Authenticator.setDefault(new Authenticator() {
        @Override
        protected PasswordAuthentication getPasswordAuthentication() {
            return (new PasswordAuthentication(args[1], args[2].toCharArray()));
        }
    });
    //LAMAccountAPI service = new LAMAccountAPI();

    URL url = LAMAccountAPI.class.getClassLoader().getResource("wsdl/ufe/ufe_account.wsdl");

    // TO AVOID SEIStub cannot be cast to ClientProxy
    LAMAccountAPI service = new LAMAccountAPI(url, LAMAccountAPI.SERVICE);
    Field delegateField = Service.class.getDeclaredField("delegate");
    delegateField.setAccessible(true);
    ServiceDelegate previousDelegate = (ServiceDelegate) delegateField.get(service);
    if (!previousDelegate.getClass().getName().contains("cxf")) {
        ServiceDelegate serviceDelegate = ((Provider) Class.forName("org.apache.cxf.jaxws.spi.ProviderImpl").newInstance())
                .createServiceDelegate(url, LAMAccountAPI.SERVICE, service.getClass());
        delegateField.set(service, serviceDelegate);
    }

    ILAMZarzadzanieKontem port = service.getBasicHttpBindingILAMZarzadzanieKontem();

    // Many various tryings
    Client client = ClientProxy.getClient(port);
    HTTPConduit http = (HTTPConduit) client.getConduit();
    http.getAuthorization().setUserName(args[1]);
    http.getAuthorization().setPassword(args[2]);
    AuthorizationPolicy policy = new AuthorizationPolicy();
    policy.setUserName(args[1]);
    policy.setPassword(args[2]);
    http.setAuthorization(policy);
    HTTPClientPolicy httpClientPolicy = new HTTPClientPolicy();
    httpClientPolicy.setConnectionTimeout(36000);
    httpClientPolicy.setAllowChunking(false);
    http.setClient(httpClientPolicy);

    List<Konto> accounts = null;
    try {
        accounts = port.pobierzKonta().getKonto();
    } catch (ILAMZarzadzanieKontemPobierzKontaSOAPExceptionFaultMessage | ILAMZarzadzanieKontemPobierzKontaDataConversionExceptionFaultMessage ilamZarzadzanieKontemPobierzKontaSOAPExceptionFaultMessage) {
        ilamZarzadzanieKontemPobierzKontaSOAPExceptionFaultMessage.printStackTrace();
    }
}

以及来自 WSDL 的策略定义:

<wsp:Policy wsu:Id="BasicHttpBinding_ILAMZarzadzanieKontem_policy">
        <wsp:ExactlyOne>
            <wsp:All>
                <http:NtlmAuthentication xmlns:http="http://schemas.microsoft.com/ws/06/2004/policy/http"/>
            </wsp:All>
        </wsp:ExactlyOne>
    </wsp:Policy>

最后，完整的堆栈跟踪:

Answer 1

这是专有 ws-policy 标记 http:NtlmAuthentication 的问题。 问题是 cxf 尝试自动满足开箱即用的 ws-policy 要求。由于此标签是专有的且非标准的，因此它会失败，因此出现异常。

从 wsdl 中删除此(整个)策略，并在没有此策略的情况下再次生成客户端。之后 ntlm 身份验证应该可以工作。
