本文所用到的WebServices服务端，取自我的上一篇文章中的例子——使用XFire开发WebServices服务端?
这里并未涉及到JSR?181?Annotations?的相关应用，具体的三种方式如下
①?通过WSDL地址来创建动态客户端?
②?通过服务端提供的接口来创建客户端?
③?使用Ant通过WSDL文件来生成客户端

第一种方式：通过WSDL地址来创建动态客户端

 
   view plain 
   print 
   ? 
  
 package?com.jadyer.client;??
 import?java.net.MalformedURLException;??
 import?java.net.URL;??
 import?org.codehaus.xfire.client.Client;??
 /**?
 ?*?通过WSDL来创建动态客户端?
 ?*?@see?此时需要在项目中引入XFire?1.2?Core?Libraries和XFire?1.2?HTTP?Client?Libraries?
 ?*/??
 public?class?ClientFromWSDL?{??
 ????public?static?void?main(String[]?args)?throws?MalformedURLException,?Exception?{??
 ????????Client?client?=?new?Client(new?URL("http://127.0.0.1:8080/XFire_demo/services/XFireServer?wsdl"));??
 ????????Object[]?results11?=?client.invoke("sayHello",?new?Object[]{"Jadyer22"});??
 ????????System.out.println(results11[0]);??
 ????}??
 }??

第二种方式：通过服务端提供的端口来创建客户端

import?java.util.List;??

import?org.codehaus.xfire.client.XFireProxyFactory;??

import?org.codehaus.xfire.service.Service;??

import?org.codehaus.xfire.service.binding.ObjectServiceFactory;??

import?com.jadyer.model.Person;??

import?com.jadyer.model.User;??

import?com.jadyer.server.HelloService;??

/**?

?*?通过Web服务端提供的接口来创建客户端?

?*?@see?客户端必须提供一个与服务端完全一致的接口，包名也要一致?

?*?@see?在本例中，需要在客户端(即该项目)中提供HelloService.java接口，以及Person和User两个POJO类?

?*?@see?并且此时需要在项目中引入XFire?1.2?Core?Libraries和XFire?1.2?HTTP?Client?Libraries?

?*/??

public?class?ClientFromInterface?{??

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

????????//首先使用XFire的ObjectServiceFactory从HelloService接口创建一个服务模型serviceModel??

????????//serviceModel包含服务的说明，换句话说，就是服务的元数据??

????????//Create?a?metadata?of?the?service??

????????Service?serviceModel?=?new?ObjectServiceFactory().create(HelloService.class);??

??????????

????????//访问的地址??

????????String?serviceURL?=?"http://127.0.0.1:8080/XFire_demo/services/XFireServer";??

??????????

????????//通过查看org.codehaus.xfire.client.XFireProxyFactory源码发现??

????????//下面两行代码与这里直接new?XFireProxyFactory()的作用是等效的??

????????//XFire?xfire?=?XFireFactory.newInstance().getXFire();??

????????//XFireProxyFactory?factory?=?new?XFireProxyFactory(xfire);??

????????//为XFire获得一个代理工厂对象??

????????//Create?a?proxy?for?the?deployed?service??

????????XFireProxyFactory?factory?=?new?XFireProxyFactory();??

????????//通过proxyFactory，使用服务模型serviceModel和服务端点URL(用来获得WSDL)??

????????//得到一个服务的本地代理，这个代理就是实际的客户端??

????????HelloService?client?=?(HelloService)factory.create(serviceModel,?serviceURL);??

????????/**?

?????????*?Invoke?the?service?

?????????*?@see?调用服务的本地代理(即实际的客户端)中的方法，便得到我们需要的WebServcie?

?????????*/??

????????/*--处理简单对象--*/??

????????String?serviceResponse?=?client.sayHello("Jadyer11");??

????????System.out.println(serviceResponse);??

????????/*--处理对象--*/??

????????User?u?=?new?User();??

????????u.setName("Jadyer99");??

????????Person?pp?=?client.getPerson(u);??

????????System.out.println(pp.getName());??

????????/*--处理List--*/??

????????List<Person>?personList?=?client.getPersonList(24,?"Jadyer88");??

????????for(Person?p?:?personList){??

????????????System.out.println(p.getName());??

????????}??

}??

这是它要用到的接口和两个POJO类

?*?Web服务提供给客户端的接口?

?*?@see?这是第二种方式创建的客户端，要用到的接口?

package?com.jadyer.server;??

import?java.util.List;??

public?interface?HelloService?{??

????public?String?sayHello(String?name);??

????public?Person?getPerson(User?u);??

????public?List<Person>?getPersonList(Integer?age,?String?name);??

}??

?*?第二种方式创建的客户端，要用到的两个POJO类?

package?com.jadyer.model;??

public?class?User?{??

????private?String?name;??

????/*--getter和setter略--*/??

package?com.jadyer.model;??

public?class?Person?{??

????private?Integer?age;??

}??

第三种方式：使用Ant通过WSDL文件来生成客户端

?*?使用Ant通过WSDL生成客户端?

?*?@see?这里的ClientFromAnt.java是我自己创建的，并非Ant生成?

?*?@see?这里要用到的JAR有：xfire-all-1.2.6.jar以及//xfire-distribution-1.2.6//lib//目录中的所有JAR包?

?*?@see?我们需要把这些JAR包都拷贝到Web?Project//WebRoot//WEB-INF//lib//目录中?

?*?@see?然后把build.xml和MyFirstXFireServer.wsdl都拷贝到下Web?Project的根目录下即可?

?*?@see?关于MyFirstXFireServer.wsdl文件，是我在WebServices服务启动后?

?*?@see?访问http://127.0.0.1:8080/XFire_demo/services/XFireServer?wsdl然后将其另存得到的?

public?class?ClientFromAnt?{??

????public?static?void?main(String[]?args)?{??

????????XFireServerClient?client?=?new?XFireServerClient();??

????????//String?url?=?"http://127.0.0.1:8080/XFire_demo/services/XFireServer";??

????????//String?result?=?client.getXFireServerHttpPort(url).sayHello("Jadyer33");??

????????//上面的两行代码，与下面的这一行代码，同效~~??

????????String?result?=?client.getXFireServerHttpPort().sayHello("Jadyer33");??

????????System.out.println(result);??

}??

用到的Ant文件，如下

<?xml?version="1.0"?encoding="UTF-8"?>??

<project?name="wsgen"?default="wsgen"?basedir=".">??
????<path?id="classpathId">??
????????<fileset?dir="./WebRoot/WEB-INF/lib">??
????????????<include?name="*.jar"?/>??
????????</fileset>??
????</path>??
??????
????<taskdef?classpathref="classpathId"?name="wsgen"?classname="org.codehaus.xfire.gen.WsGenTask"/>??
????<target?name="wsgen"?description="generate?client">??
????????<wsgen?outputDirectory="./src/"?wsdl="MyFirstXFireServer.wsdl"?binding="xmlbeans"?package="com.jadyer.client"?overwrite="true"/>??
????</target>??
</project>??

也可以使用下面的这个Ant文件

<project?name="xfireAnt"?basedir="."?default="createClientCode">??

????<property?name="xfirelib"?value="${basedir}/WebRoot/WEB-INF/lib"/>??

????<property?name="sources"?value="${basedir}/src"/>??

????<path?id="classpath">??

????????<fileset?dir="${xfirelib}">??

????????????<include?name="*.jar"/>??

????<target?name="createClientCode">??

????????<taskdef?name="wsgen"?classname="org.codehaus.xfire.gen.WsGenTask"?classpathref="classpath"/>??

????????<wsgen?outputDirectory="${sources}"?wsdl="http://127.0.0.1:8080/XFire_demo/services/XFireServer?wsdl"?package="com.jadyer.client"?overwrite="true"/>??

????</target>??

</project>??

最后我再把MyFirstXFireServer.wsdl的内容，附加上
