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
