java使用soap方式简单实现webservice

java类:




import java.net.URL;

 

import javax.xml.namespace.QName;

import javax.xml.soap.MessageFactory;

import javax.xml.soap.SOAPBody;

import javax.xml.soap.SOAPBodyElement;

import javax.xml.soap.SOAPConstants;

import javax.xml.soap.SOAPEnvelope;

import javax.xml.soap.SOAPMessage;

import javax.xml.ws.Dispatch;

import javax.xml.ws.Service;

 

import org.w3c.dom.Document;

 

public class Receive {

 

    /**

     * @param args

     */

    @SuppressWarnings("unused")

    public static void main(String[] args) throws Exception {

        String ns = "http://axisversion.sample";

        String wsdlUrl = "http://127.0.0.1:8080/axis2/services/Version?wsdl";

        //1、创建服务(Service)

        URL url = new URL(wsdlUrl);

        QName sname = new QName(ns,"Version");

        Service service = Service.create(url,sname);

                    

        //2、创建Dispatch

        Dispatch<SOAPMessage> dispatch = service.createDispatch(new QName(ns,"VersionHttpSoap11Endpoint"),SOAPMessage.class,Service.Mode.MESSAGE);

                    

        //3、创建SOAPMessage

        SOAPMessage msg = MessageFactory.newInstance(SOAPConstants.SOAP_1_1_PROTOCOL).createMessage();

        SOAPEnvelope envelope = msg.getSOAPPart().getEnvelope();

        SOAPBody body = envelope.getBody();

                    

        //4、创建QName来指定消息中传递数据

        QName ename = new QName(ns,"getVersion","axis");//<nn:add xmlns="xx"/>

        SOAPBodyElement ele = body.addBodyElement(ename);

        // 传递参数

//        ele.addChildElement("a").setValue("22");  

//        ele.addChildElement("b").setValue("33");  

        msg.writeTo(System.out);

        System.out.println("\n invoking.....");

                            

        //5、通过Dispatch传递消息,会返回响应消息

        SOAPMessage response = dispatch.invoke(msg);

        response.writeTo(System.out);

        System.out.println();

                    

        //6、响应消息处理,将响应的消息转换为dom对象

        Document doc = response.getSOAPPart().getEnvelope().getBody().extractContentAsDocument();

        String str = doc.getElementsByTagName("ns:return").item(0).getTextContent();

        System.out.println(str);

 

    }

 

}
