java调用.net webservice的完整实例

Java客户端调用Web Service的一般有以下三种方式：
生成的stub、proxy(动态代理)以及dispatch(动态调用接口)。dispatch又分为payload和message两种方式。
这个实例仅就dispatch的message方式进行介绍。

C#代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.Web.Services.Description;

namespace WebService1
{
/// <summary>
/// Service1 的摘要说明
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消对下行的注释。
// [System.Web.Script.Services.ScriptService]
[SoapDocumentService(RoutingStyle = SoapServiceRoutingStyle.RequestElement)] 
public class Service1 : System.Web.Services.WebService
{


[WebMethod]
public string HelloWorld(string strHost)
{
return "Hello World, "+strHost;
}
}
}

Java调用程序

import java.util.Map;

import javax.xml.namespace.QName;
import javax.xml.soap.MessageFactory;
import javax.xml.soap.SOAPBody;
import javax.xml.soap.SOAPBodyElement;
import javax.xml.soap.SOAPElement;
import javax.xml.soap.SOAPMessage;
import javax.xml.ws.BindingProvider;
import javax.xml.ws.Dispatch;
import javax.xml.ws.Service;
import javax.xml.ws.WebServiceException;
import javax.xml.ws.soap.SOAPBinding;

public class WebServiceTest {

/**
* @param args
*/
public static final String targetNamespace = "http://tempuri.org/";
//服务名
public static final String serName = "Service1";
//端口名
public static final String pName = "5756";
//服务地址
public static final String endpointAddress = "http://localhost:5756/Service1.asmx?wsdl";
//方法名
public static final String OPER_NAME = "HelloWorld";
//参数名
public static final String INPUT_NMAE = "strHost";

public static void main(String[] args) throws Exception {
QName serviceName = new QName(targetNamespace, serName);
QName portName = new QName(targetNamespace, pName);

javax.xml.ws.Service service = Service.create(serviceName);
service.addPort(portName, SOAPBinding.SOAP11HTTP_BINDING, endpointAddress);

Dispatch<SOAPMessage> dispatch = service.createDispatch(portName,
SOAPMessage.class, Service.Mode.MESSAGE);

BindingProvider bp = (BindingProvider) dispatch;
Map<String, Object> rc = bp.getRequestContext();
rc.put(BindingProvider.SOAPACTION_USE_PROPERTY, Boolean.TRUE);
rc.put(BindingProvider.SOAPACTION_URI_PROPERTY, OPER_NAME);
MessageFactory factory = ((SOAPBinding)bp.getBinding()).getMessageFactory();

SOAPMessage request = factory.createMessage();
SOAPBody body = request.getSOAPBody();
QName payloadName = new QName(targetNamespace, OPER_NAME); 
SOAPBodyElement payload = body.addBodyElement(payloadName);

SOAPElement message = payload.addChildElement(INPUT_NMAE);
message.addTextNode("xyz");
SOAPMessage reply = null;

try
{
reply = dispatch.invoke(request);
}
catch (WebServiceException wse)
{
wse.printStackTrace();
}
SOAPBody soapBody = reply.getSOAPBody();
SOAPBodyElement nextSoapBodyElement = (SOAPBodyElement)soapBody.getChildElements().next (); 
SOAPElement soapElement = (SOAPElement)nextSoapBodyElement.getChildElements().next();

System.out.println("获取回应信息为：" + soapElement.getValue()); 
}
}

输出：

Hello World, xyz
