【问题描述】：

我正在尝试向JAX-WS 网络服务发送请求，该服务受 HTTP 基本身份验证保护。服务的web.xml文件包含以下语句：

<security-constraint>
    <web-resource-collection>
      <web-resource-name>secured services</web-resource-name>
      <url-pattern>/services/PortalWebservice/*</url-pattern>
    </web-resource-collection>
    <auth-constraint>
      <role-name>onlineadapter</role-name>
    </auth-constraint>
  </security-constraint> 
  <security-role>
    <role-name>onlineadapter</role-name>
  </security-role>
  <login-config>   
   <auth-method>BASIC</auth-method>   
   <realm-name>onlineadapter</realm-name>   
  </login-config>

我的 tomcat-user.xml 包含这个：

<role rolename="onlineadapter"/>
<user username="onlineadapter" password="onlineadapter" roles="onlineadapter"/>

然后我尝试在运行时创建一个客户端，如下所示：

int timeOut = 60000;
IPortaladapterWebservice service = new PortaladapterWebservice(new URL("http://localhost:8080/OnlineAdapter/services/PortaladapterWebservice")).getPortaladapterWebservicePort();
((BindingProvider) service).getRequestContext().put(BindingProviderProperties.CONNECT_TIMEOUT, timeOut);
if (aUser != null && !aUser.equals("") && aPassword != null && !aPassword.equals(""))
{
    ((BindingProvider) service).getRequestContext().put(BindingProvider.USERNAME_PROPERTY, "onlineadapter");
    ((BindingProvider) service).getRequestContext().put(BindingProvider.PASSWORD_PROPERTY, "onlineadapter");
}

问题：每当我调用getPortaladapterWebservicePort 时，我都会收到以下错误：

com.sun.xml.ws.wsdl.parser.InaccessibleWSDLException: 2 counts of InaccessibleWSDLException.

java.io.IOException: Server returned HTTP response code: 401 for URL: http://localhost:8080/OnlineAdapter/services/PortaladapterWebservice
java.io.IOException: Server returned HTTP response code: 401 for URL: http://localhost:8080/OnlineAdapter/services/PortaladapterWebservice?wsdl

我猜状态码 401 与我的客户未获得请求授权有关。那么为什么在我什至能够设置用户和密码之前出现错误？这在JAX-WS 客户端中是如何完成的？

【解决方案1】：

好的，我找到了一种方法来使用Authenticator，它必须在查询端口之前设置：

    if (aUser != null && !aUser.equals("") && aPassword != null && !aPassword.equals(""))
    {
        Authenticator.setDefault(getDefaultAuthenticator(aUser, aPassword));
    }

    service = new PortaladapterWebservice(new URL(mUrl)).getPortaladapterWebservicePort();
    ((BindingProvider) service).getRequestContext().put(BindingProviderProperties.CONNECT_TIMEOUT, 60000);

其中getDefaultAuthenticator()方法定义为：

private Authenticator getDefaultAuthenticator (String aUser, String aPassword)
    {
        return new Authenticator() 
        {
            @Override
            protected PasswordAuthentication getPasswordAuthentication()
            {
                return new PasswordAuthentication(aUser, aPassword.toCharArray());
            }
        };
    }
