hessian——客户端动态代理

客户端代码：

String urlString = "http://localhost/hessian/testService";HessianProxyFactory factory = new HessianProxyFactory();TestService testService = (TestService)factory.create(TestService.class,urlString);

?

 public Object create(Class<?> api, URL url, ClassLoader loader)  {    if (api == null)      throw new NullPointerException("api must not be null for HessianProxyFactory.create()");    InvocationHandler handler = null;    handler = new HessianProxy(url, this, api);    return Proxy.newProxyInstance(loader,                                  new Class[] { api,                                                HessianRemoteObject.class },                                  handler);  }

?handler = new HessianProxy(url, this, api);是关键，利用java动态代理，创建了一个HessianProxy对象来代理对Service对象的方法调用，具体HessianProxy的代理方式就是通过网络连接，调用远程的方法（见
