Question

我正在尝试连接到使用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：org.apache.cxf.ws.policy.PolicyException：没有任何策略选择可以满足。也许还有另一种方法可以进行身份验证。

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();
    }
}

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

专有的ws-policy标记http:NtlmAuthentication存在问题。问题是cxf试图自动满足开箱即用的ws-policy要求。由于此标记是专有的而非标准的，因此失败，因此例外。

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。
