java建用webservice.doc

一、利用jdk web服务api实现，这里使用基于 SOAP message 的 Web 服务 1.首先建立一个Web services EndPoint：Java代码package Hello;import javax.jws.WebService;import javax.jws.WebMethod;import javax.xml.ws.Endpoint;WebServicepublic class Hello WebMethodpublic String hello(String name) return Hello, + name + n;public static void main(String args) / create and publish an endpointHello hello = new Hello();Endpoint endpoint = Endpoint.publish(http:/localhost:8080/hello, hello);package Hello;import javax.jws.WebService;import javax.jws.WebMethod;import javax.xml.ws.Endpoint;WebServicepublic class Hello WebMethodpublic String hello(String name) return Hello, + name + n;public static void main(String args) / create and publish an endpointHello hello = new Hello();Endpoint endpoint = Endpoint.publish(http:/localhost:8080/hello, hello);2.使用 apt 编译 Hello.java(例：apt -d 存放编译后的文件目录 Hello.java ) ,会生成 jaws目录3.使用java Hello.Hello运行，然后将浏览器指向http:/localhost:8080/hello?wsdl就会出现下列显示4.使用wsimport 生成客户端使用如下：wsimport -p . -keep http:/localhost:8080/hello?wsdl5.客户端程序：Java代码class HelloClientpublic static void main(String args) HelloService service = new HelloService();Hello helloProxy = service.getHelloPort();String hello = helloProxy.hello(你好);System.out.println(hello);class HelloClientpublic static void main(String args) HelloService service = new HelloService();Hello helloProxy = service.getHelloPort();String hello = helloProxy.hello(你好);System.out.println(hello);二、使用xfire，我这里使用的是myeclipse集成的xfire进行测试的利用xfire开发WebService，可以有三种方法：1一种是从javabean 中生成；2 一种是从wsdl文件中生成；3 还有一种是自己建立webservice步骤如下：用myeclipse建立webservice工程，目录结构如下：首先建立webservice接口，代码如下：Java代码package com.myeclipse.wsExample;/Generated by MyEclipsepublic interface IHelloWorldService public String example(String message);package com.myeclipse.wsExample;/Generated by MyEclipsepublic interface IHelloWorldService public String example(String message);Java代码package com.myeclipse.wsExample;/Generated by MyEclipsepublic class HelloWorldServiceImpl implements IHelloWorldService public String example(String message) return message;package com.myeclipse.wsExample;/Generated by MyEclipsepublic class HelloWorldServiceImpl implements IHelloWorldService public String example(String message) return message;修改service.xml 文件，加入以下代码：Xml代码HelloWorldServicecom.myeclipse.wsExample.IHelloWorldServicecom.myeclipse.wsExample.HelloWorldServiceImplwrappedliteralapplicationHelloWorldServicecom.myeclipse.wsExample.IHelloWorldServicecom.myeclipse.wsExample.HelloWorldServiceImplwrappedliteralapplication把整个项目部署到tomcat服务器中 ，打开浏览器，输入http:/localhost:8989/HelloWorld/services/HelloWorldService?wsdl客户端实现如下：Java代码package com.myeclipse.wsExample.client;import .MalformedURLException;import .URL;import org.codehaus.xfire.XFireFactory;import org.codehaus.xfire.client.Client;import org.codehaus.xfire.client.XFireProxyFactory;import org.codehaus.xfire.service.Service;import org.codehaus.xfire.service.binding.ObjectServiceFactory;import com.myeclipse.wsExample.IHelloWorldService;public class HelloWorldClient public static void main(String args) throws MalformedURLException, Exception / TODO Auto-generated method stubService s=new ObjectServiceFactory().create(IHelloWorldService.class);XFireProxyFactory xf=new XFireProxyFactory(XFireFactory.newInstance().getXFire();String url=http:/localhost:8989/HelloWorld/services/HelloWorldService;tryIHelloWorldService hs=(IHelloWorldService) xf.create(s,url);String st=hs.example(zhangjin);System.out.print(st);catch(Exception e)e.printStackTrace();package com.myeclipse.wsExample.client;import .MalformedURLException;import .URL;import org.codehaus.xfire.XFireFactory;import org.codehaus.xfire.client.Client;import org.codehaus.xfire.client.XFireProxyFactory;import org.codehaus.xfire.service.Service;import org.codehaus.xfire.service.binding.ObjectServiceFactory;import com.myeclipse.wsExample.IHelloWorldService;public class HelloWorldClient public static void main(String args) throws MalformedURLException, Exception / TODO Auto-generated method stubService s=new ObjectServiceFactory().create(IHelloWorldService.class);XFireProxyFactory xf=new XFireProxyFactory(XFireFactory.newInstance().getXFire();String url=http:/localhost:8989/HelloWorld/services/HelloWorldService;tryIHelloWorldService hs=(IHelloWorldService) xf.create(s,url);String st=hs.example(zhangjin);System.out.print(st);catch(Exception e)e.printStackTrace();这里再说点题外话，有时候我们知道一个wsdl地址，比如想用java客户端引用.net 做得webservice，使用myeclipse引用，但是却出现无法通过验证的错误，这时我们可以直接在类中引用，步骤如下：Java代码public static void main(String args) throws MalformedURLException, Exception / TODO Auto-generated method stubService s=new ObjectServiceFactory().create(IHelloWorldService.class);XFireProxyFactory xf=new XFireProxyFactory(XFireFactory.newInstance().getXFire();/远程调用.net开发的webserviceClient c=new Client(new URL(/webservices/qqOnlineWebService.asmx?wsdl);Object o=c.invoke(qqCheckOnline, new String531086641,591284436);/调用.net本机开发的webserviceClient c1=new Client(new URL(http:/localhost/zj/Service.asmx?wsdl);Object o1=c1.invoke(HelloWorld,new String);public static void main(String args) throws MalformedURLException, Exception / TODO Auto-generated method stubService s=new ObjectServiceFactory().create(IHelloWorldService.class);XFireProxyFactory xf=new XFireProxyFactory(XFireFactory.newInstance().getXFire();/远程调用.net开发的webserviceClient
