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 stub ,如 here 所述来自 EWS 的 Services.wsdl 文件。现在我已经编写了使用这些 stub 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

at com.xyz.abc.test.ExchangeDevelopmentTest.main(ExchangeDevelopmentTest.java:35)
正如我们在上面看到的那样,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 stub 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
表示它得到了 HTTP 响应代码:401
,这是针对未经授权的访问。但是我已经正确指定了用户名和密码,并且还在 keystore 中包含了所需的证书。我完全不知道这个异常是从哪里来的。
我写的类代码:
交换 validator
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());
}
}
}
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);
}
}
最佳答案
为什么在您可以拥有本地副本时访问远程 WSDL 文档文件(和架构文件)?当然,访问端点仍然需要安全性。
首先,你需要根据环境的类加载器。
// Java EE Enviroment
ClassLoader cl = Thread.currentThread().getContextClassLoader();
// Java Standalone Enviroment
ClassLoader cl = ClassLoader.getSystemClassLoader();
接下来,在您的项目中本地存储一份 WSDL 文档文件(以及方案文件,如果需要的话)。
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();
如果需要身份验证才能访问 web 服务端点,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 .
