1.新建接口:FileServer

import javax.activation.DataHandler;import javax.jws.WebMethod;import javax.jws.WebService;import javax.jws.soap.SOAPBinding;import javax.jws.soap.SOAPBinding.Style;/** *  * @author Administrator TODO */@WebService@SOAPBinding(style = Style.RPC)public interface FileServer {// download a File from server@WebMethodpublic DataHandler downloadFile(String fileName);}

2.实现类:

package com.it.filedown;import javax.activation.DataHandler;import javax.activation.FileDataSource;import javax.jws.WebService;import javax.xml.ws.soap.MTOM;/** *  * @author Administrator TODO */@MTOM@WebService(endpointInterface = "com.it.filedown.FileServer")public class FileServerImpl implements FileServer {public DataHandler downloadFile(String fileName) {FileDataSource dataSource = new FileDataSource("c:/test/"+fileName);DataHandler fileDataHandler = new DataHandler(dataSource);return fileDataHandler;}}

4.发布类:FileDownServerPublisher

package com.it.filedown;import javax.xml.ws.Endpoint;/** *  * @author Administrator TODO */public class FileDownServerPublisher {public static void main(String[] args) {// 第一个参数是发布的URL// 第二个参数是SIB实现Endpoint.publish("http://127.0.0.1:10101/filedown", new FileServerImpl());}}

3.打开cmd命令窗口切换到空白目录,输入:wsimport -keep http://localhost:10101/filedown?wsdl

4.复制生成的类到客户端的javaproject新建一个client类:

package com.it.client;import java.io.FileNotFoundException;import java.io.FileOutputStream;import java.io.IOException;import java.net.MalformedURLException;import java.net.URL;import javax.xml.namespace.QName;import javax.xml.ws.Service;import com.it.filedown.FileServer;/** *  * @author Administrator TODO */public class FileDownClient {public static void main(String[] args) {try {URL url = new URL("http://localhost:10101/filedown?wsdl");QName qname = new QName("http://filedown.it.com/","FileServerImplService");Service service = Service.create(url, qname);FileServer fileServer = service.getPort(FileServer.class);byte[]  bytes = fileServer.downloadFile("123.txt");FileOutputStream outputStream = new FileOutputStream("E:/test.txt");outputStream.write(bytes);outputStream.flush();outputStream.close();System.out.println(" Download Successful!");} catch (MalformedURLException e) {e.printStackTrace();} catch (FileNotFoundException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}}}

5.运行服务的FileDownServerPublisher类然后运行FileDownClient
