我正在尝试为 Exchange Web 服务编写自定义 Java 客户端。我已经使用EWS 的 Services.wsdl 文件wsimport中解释的工具生成了客户端存根。现在我已经编写了使用这些存根的代码。我收到以下异常：

Exception in thread "main" com.sun.xml.internal.ws.wsdl.parser.InaccessibleWSDLException: 2   counts of InaccessibleWSDLException.

java.io.IOException: Got Server returned HTTP response code: 401 for URL: https://host.domain.com/ews/Services.wsdl while opening stream from https://host.domain.com/ews/Services.wsdl

正如我们在上面看到的，ExchangeDevelopmentTest一个使用另一个类的客户端ExchangeAuthenticator又使用生成的客户端存根ExchangeWebService。但是在堆栈跟踪中，我收到了来自未知来源的错误，大概是 JDK 的 JAR。

IOException说它得到了，那HTTP response code: 401是未经授权的访问。但是我已经正确指定了用户名和密码，并且还在密钥库中包含了所需的证书。我完全没有方向，这个异常来自哪里。

我写的类的代码：

交换验证器 

public class ExchangeAuthenticator {    
/**
 * Obtains an authenticated ExchangeServicePortType with given credentials.
 *     
 */
    public ExchangeServicePortType getExchangeServicePort(String username, String password, String domain, URL wsdlURL) throws MalformedURLException {
        // Concatinate our domain and username for the UID needed in authentication.
        String uid = "domain" + "\\" + "uname";

        // Create an ExchangeWebService object that uses the supplied WSDL file, wsdlURL.
        ExchangeWebService exchangeWebService = new ExchangeWebService(wsdlURL, new QName("<a href=\"http://schemas.microsoft.com/exchange/services/2006/messages\">http://schemas.microsoft.com/exchange/services/2006/messages</a>", "ExchangeWebService"));
        ExchangeServicePortType port = exchangeWebService.getExchangeWebPort();
        // Supply your username and password when the ExchangeServicePortType is used for binding in the SOAP request.
        ((BindingProvider)port).getRequestContext().put(BindingProvider.USERNAME_PROPERTY, uid);
        ((BindingProvider)port).getRequestContext().put(BindingProvider.PASSWORD_PROPERTY, password);

        return port;
    }
}

交流发展测试

public class ExchangeDevelopmentTest {    
    public static void main (String[] args) {
        ExchangeAuthenticator exchangeAuthenticator = new ExchangeAuthenticator();

        // Print statement so we can easily see where our statements start in the Java console.
        System.out.println("Let's get started!");

        try {
            // Create a URL object which points at the .wsdl we deployed in the previous step.
            URL wsdlURL = new URL("https://172.17.245.196/ews/Services.wsdl");
            //URL wsdlURL = new URL("<a href=\"https://172.17.245.196/ews/Services.wsdl\">https://172.17.245.196/ews/Services.wsdl</a>");
            // Call to the class we just created to return an ExchangeServicePortType with authentication credentials.
            ExchangeServicePortType port = exchangeAuthenticator.getExchangeServicePort("uname", "password@123", "domain", wsdlURL);

            // Prints out the default toString() for the ExchangeServicePortType.
            System.out.println(port.toString());
        } catch (MalformedURLException ex) {
            // Catch any errors that may occur.
            Logger.getLogger(ExchangeDevelopmentTest.class.getName()).log(Level.SEVERE, null, ex);
            System.out.println(ex.getMessage()+"\n"+ex.getStackTrace());
        }
    }
}

交换网络服务

由 JAX-WS 使用wsimport工具生成，删除了其他构造函数和方法。仅保留第 58 行调用super（此处Service为类）构造函数的构造函数。

@WebServiceClient(name = "ExchangeWebService", targetNamespace =     "http://schemas.microsoft.com/exchange/services/2006/messages", wsdlLocation = "file:/C:/Services.wsdl")
public class ExchangeWebService extends Service
{ 
    private final static URL EXCHANGEWEBSERVICE_WSDL_LOCATION;
    private final static WebServiceException EXCHANGEWEBSERVICE_EXCEPTION;
    private final static QName EXCHANGEWEBSERVICE_QNAME = new QName("http://schemas.microsoft.com/exchange/services/2006/messages", "ExchangeWebService");

    static {
        URL url = null;
        WebServiceException e = null;
        try {
            url = new         URL("file:/C:/workspace/Server%20files/Client%20files/Services.wsdl");
        } catch (MalformedURLException ex) {
            e = new WebServiceException(ex);
        }
        EXCHANGEWEBSERVICE_WSDL_LOCATION = url;
        EXCHANGEWEBSERVICE_EXCEPTION = e;
    }

    //other constructos & methods removed
    //line 58
    public ExchangeWebService(URL wsdlLocation, QName serviceName) {
        super(wsdlLocation, serviceName);
    }    
}

当您可以拥有本地副本时，为什么还要访问远程 WSDL 文档文件（和模式文件） ？当然，访问端点仍然需要安全性。

首先，根据环境需要类加载器。

// Java EE Enviroment
ClassLoader cl = Thread.currentThread().getContextClassLoader();

// Java Standalone Enviroment
ClassLoader cl = ClassLoader.getSystemClassLoader();

接下来，在本地存储项目中 WSDL 文档文件（以及方案文件，如果需要）的副本。

URL wsdlLocation = cl.getResource("com/mahesha999/ExchangeWebService.wsdl");
QName qName = new QName(
    "http://schemas.microsoft.com/exchange/services/2006/messages", 
    "ExchangeWebService"
);

ExchangeWebService exchangeWebService = new ExchangeWebService(wsdlLocation, 
        qName);
ExchangeServicePortType port = exchangeWebService.getExchangeWebPort();

如果访问 web 服务端点需要身份验证，其最基本的形式如下：

BindingProvider provider = (BindingProvider) port;
Map<String, Object> context = provider.getRequestContext();
context.put(BindingProvider.USERNAME_PROPERTY, username);
context.put(BindingProvider.PASSWORD_PROPERTY, password);

如果您需要处理证书之类的事情，最好看看Securing WebLogic Web Services。

你是这样添加用户名和密码的吗？

    ShopingCart sc = scs.getShopingCartPort();
    Map requestContext = ((BindingProvider)sc).getRequestContext();
    requestContext.put(BindingProvider.USERNAME_PROPERTY, userName);
    requestContext.put(BindingProvider.PASSWORD_PROPERTY, password);

您没有提供有问题的客户代码。你在使用代理吗？然后你必须在上面提供你的代理用户名和密码。
