CXF之用Dispatch处理异步调用实例 - fhd001的专栏 - 博客频道 - CSDN.NET

服务接口：

 

package cxf.server;
import javax.jws.WebService;
@WebService
public interface HelloWorld {
    String sayHi(String text);
}

 

 

 

服务接口实现：

 

package cxf.server;
import javax.jws.WebService;
@WebService(endpointInterface = "cxf.server.HelloWorld")
public class HelloWorldImpl implements HelloWorld {
    public String sayHi(String text) {

        try {
            Thread.sleep(30);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        System.out.println("sayHi called");
        return "Hello " + text;
    }
}

 

 

 

服务端配置:

客户端调用1---轮询方式异步调用：

 

package cxf.client;
import java.io.InputStream;
import java.net.URL;
import javax.xml.namespace.QName;
import javax.xml.soap.MessageFactory;
import javax.xml.soap.SOAPMessage;
import javax.xml.transform.dom.DOMSource;
import javax.xml.ws.Dispatch;
import javax.xml.ws.Response;
import javax.xml.ws.Service;
public final class Client1 {
    public static void main(String args[]) throws Exception {

        URL wsdlUrl = new URL("http://localhost:8085/cxf-dispatch-test/service/HelloWorld?wsdl");
        QName serviceName = new QName("http://server.cxf/", "HelloWorldService");
        Service service = Service.create(wsdlUrl,serviceName);
        QName portName = new QName("http://server.cxf/", "HelloWorldPort");
        Dispatch<DOMSource> disp = service.createDispatch(portName, DOMSource.class, Service.Mode.MESSAGE);

        InputStream input = Client1.class.getResourceAsStream("soap1.xml");
        MessageFactory factory = MessageFactory.newInstance ();
        SOAPMessage soapMessage = factory.createMessage(null, input);
        DOMSource dom = new DOMSource(soapMessage.getSOAPPart());

        //轮询方式
        Response<DOMSource> rsp = disp.invokeAsync(dom);
        while(!rsp.isDone()){
            Thread.sleep(5);
            System.out.println("sleep 5");
        }
        DOMSource domRsp = rsp.get();
        System.out.println(domRsp.getNode().getLastChild().getNodeName());
        System.out.println(domRsp.getNode().getLastChild().getTextContent());
    }
}

 

 

 

客户端调用2---回调方式异步调用：

 

package cxf.client;
import java.io.InputStream;
import java.net.URL;
import java.util.concurrent.Future;
import javax.xml.namespace.QName;
import javax.xml.soap.MessageFactory;
import javax.xml.soap.SOAPMessage;
import javax.xml.ws.Dispatch;
import javax.xml.ws.Service;
public final class Client2 {
    public static void main(String args[]) throws Exception {

        URL wsdlUrl = new URL("http://localhost:8085/cxf-dispatch-test/service/HelloWorld?wsdl");
        QName serviceName = new QName("http://server.cxf/", "HelloWorldService");
        Service service = Service.create(wsdlUrl,serviceName);
        QName portName = new QName("http://server.cxf/", "HelloWorldPort");
        Dispatch<SOAPMessage> disp = service.createDispatch(portName, SOAPMessage.class, Service.Mode.MESSAGE);

        InputStream input = Client2.class.getResourceAsStream("soap1.xml");
        MessageFactory factory = MessageFactory.newInstance ();
        SOAPMessage soapMessage = factory.createMessage(null, input);

        MyAsyncHandler<SOAPMessage> handler = new MyAsyncHandler<SOAPMessage>();

        //回调方式
        Future<?> rsp = disp.invokeAsync(soapMessage, handler);
        while(!rsp.isDone()){
            Thread.sleep(5);
            System.out.println("aaaaaaa");
        }
        SOAPMessage soapRsp = (SOAPMessage)rsp.get();
        System.out.println(soapRsp.getSOAPBody().getNodeName());
        System.out.println(soapRsp.getSOAPBody().getLastChild().getTextContent());

    }
}

 

 

 

回调方式的AsyncHandler实现类:

 

package cxf.client;
import javax.xml.ws.AsyncHandler;
import javax.xml.ws.Response;
public class MyAsyncHandler<T> implements AsyncHandler<T> {
    /**
     * 这个回调类必须实现handleResponse()方法，它被调用由CXF运行时通知客户端响应已经到达。
    */
    @Override
    public void handleResponse(Response<T> res) {

        System.out.println("eeeeee");

    }
}
