public class ClientFromInterface {

 //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());

/**
 * 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
