我試圖訪問需要第三方Web服務我創建一個傳遞時間信息，用戶名和密碼的安全頭。我在網上搜索了一些工作示例，並嘗試了很多方法。我試圖用Java 6內置的內容來做到這一點。我不確定我做錯了什麼。在從WSDL生成我的Web服務客戶端類後，我在下面創建了Handler。com.sun.xml.ws.message.saaj.SAAJHeader無法轉換爲com.sun.xml.ws.security.opt.impl.outgoing.SecurityHeader
import java.util.Set;
import java.util.TimeZone;
import javax.xml.namespace.QName;
import javax.xml.soap.Node;
import javax.xml.soap.SOAPElement;
import javax.xml.soap.SOAPEnvelope;
import javax.xml.soap.SOAPFactory;
import javax.xml.soap.SOAPHeader;
import javax.xml.soap.SOAPMessage;
import javax.xml.soap.Text;
import javax.xml.ws.handler.MessageContext;
import javax.xml.ws.handler.soap.SOAPHandler;
import javax.xml.ws.handler.soap.SOAPMessageContext;
public class MyHeaderHandler implements SOAPHandler<SOAPMessageContext>
{
public boolean handleMessage(SOAPMessageContext context)
{
String prefixUri = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-";
String uri = prefixUri + "wssecurity-secext-1.0.xsd";
String uta = prefixUri + "wssecurity-utility-1.0.xsd";
String ta = prefixUri + "username-token-profile-1.0#PasswordText";
Boolean isRequest = (Boolean)context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
if(isRequest)
{
try
{
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:dd.SSS'Z'");
formatter.setTimeZone(TimeZone.getTimeZone("GMT"));
java.util.Date created = new java.util.Date();
java.util.Date expires = new java.util.Date(created.getTime() + (5l * 60l * 1000l));
SOAPMessage soapMsg = context.getMessage();
SOAPEnvelope soapEnv = soapMsg.getSOAPPart().getEnvelope();
SOAPHeader soapHeader = soapEnv.getHeader();
if (soapHeader == null)
soapHeader = soapEnv.addHeader();
SOAPFactory factory = SOAPFactory.newInstance();
SOAPElement securityElem = factory.createElement("Security", "o", uri);
securityElem.addAttribute(QName.valueOf("s:mustUnderstand"), "0");
SOAPElement timestampElem = factory.createElement("Timestamp", "u", uta);
timestampElem.addAttribute(QName.valueOf("xmlns:u"), uta);
timestampElem.addAttribute(QName.valueOf("Id"), "_0");
SOAPElement elem = factory.createElement("Created", "u", uta);
elem.addTextNode(formatter.format(created));
timestampElem.addChildElement(elem);
elem = factory.createElement("Expires", "u", uta);
elem.addTextNode(formatter.format(expires));
timestampElem.addChildElement(elem);
securityElem.addChildElement(timestampElem);
SOAPElement usernameElem = factory.createElement("UsernameToken", "o", uri);
elem = factory.createElement("Username", "o", uri);
elem.addTextNode("xxxxx");
usernameElem.addChildElement(elem);
elem = factory.createElement("Password", "o", uri);
elem.addTextNode("xxxxx");
elem.addAttribute(QName.valueOf("Type"), ta);
usernameElem.addChildElement(elem);
securityElem.addChildElement(usernameElem);
soapHeader.addChildElement(securityElem);
}
catch(Exception e)
{
System.out.println("Handler error!!!! - " + e);
}
}
return true;
}
public boolean handleFault(SOAPMessageContext context)
{
return true;
}
public void close(MessageContext context)
{
}
public Set<QName> getHeaders()
{
return null;
}
}
接下來，我編寫我的測試程序來附加處理程序並嘗試調用Web服務。
import java.util.ArrayList;
import java.util.List;
import javax.xml.namespace.QName;
import javax.xml.ws.handler.Handler;
import javax.xml.ws.handler.HandlerResolver;
import javax.xml.ws.handler.PortInfo;
import org.tempuri.ServiceName;
import org.tempuri.IServiceName;
public class test
{
public static void main(String[] args)
throws Exception
{
ServiceName service = new ServiceName(new URL("https://url.to.service/services/ServiceName.svc?wsdl"), new QName("http://org.tempuri/", "ServiceName"));
service.setHandlerResolver(new HandlerResolver()
{
public List<Handler> getHandlerChain(PortInfo portInfo)
{
List<Handler> handlerList = new ArrayList<Handler>();
handlerList.add(new MyHeaderHandler());
return handlerList;
}
});
IServiceName binding = service.getBasicHttpBindingIServiceName();
ArrayLiist results = binding.getMyData("my parm");
System.out.println("Size: " + results.size());
}
}
當我運行它，我得到以下錯誤在那裏我做binding.getMyData行（）：

每一個方法，我嘗試在相同的點結束。我如何解決這個問題？我無法弄清楚如何創建SecurityHeader放置到標題中。任何幫助將不勝感激。一個可行的例子會很棒。
謝謝！
