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);

    }

}
