通过客户端存根访问WSDL时Java InaccessibleWSDLException

导读:我正在尝试为Exchange Web服务编写自定义 Java客户端. 我已经使用wsimport工具生成了客户端存根,如EWS的Services.wsdl文件中的 here所述.现在我编写了使用这些存根的代码.我得到以下异常: Exception in thread "main" com.sun.xml.internal.ws.wsdl.parser.

我已经使用wsimport工具生成了客户端存根,如EWS的Services.wsdl文件中的 here所述.现在我编写了使用这些存根的代码.我得到以下异常:

at com.xyz.abc.test.ExchangeDevelopmentTest.main(ExchangeDevelopmentTest.java:35)

正如我们在上面所看到的,ExchangeDevelopmentTest是一个使用另一个类ExchangeAuthenticator的客户端,后者又使用生成的客户端存根ExchangeWebService.但是在堆栈跟踪中我得到了来自Unknown Sources的错误,大概是JDK的JAR.

IOException表示它有HTTP响应代码:401,用于未经授权的访问.但我已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.这个异常的来源,我完全没有方向性.

我写的类的代码:

ExchangeAuthenticator

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;
    }
}

ExchangeDevelopmentTest

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());
        }
    }
}

ExchangeWebService

由JAX-WS使用wsimport工具生成,删除了其他构造函数和方法.只保留第58行中调用super(此处为Service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);
    }    
}

解决方法

为什么在可以拥有本地副本时访问远程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,您需要根据环境加载类.

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

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

接下来,在项目中本地存储WSDL文档文件的副本(以及方案文件,如果需要).

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,则最基本的形式如下:

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

如果你需要处理证书等等,最好看看Securing WebLogic Web Services.
