使用AOP微型框架的例子

2022-07-15 80酷酷网 80kuku.com

在基于前两篇文章给出的AOP微型框架的实现的基础上，我们可以写个例子来测试一下了：）

public class AopControlProxyFactory : IAopProxyFactory
{
  #region IAopProxyFactory 成员
  public AopProxyBase CreateAopProxyInstance(MarshalByRefObject obj, Type type)
  {
   return new AopControlProxy(obj ,type) ;
  }
  #endregion
}

//自定义真实代理
public class AopControlProxy : AopProxyBase
{
public AopControlProxy(MarshalByRefObject obj ,Type type) : base(obj ,type)
{

}

  public override void PreProcess(IMessage requestMsg)
  {
   Console.Write("Begin Aop !") ;
  }

  public override void PostProcess(IMessage requestMsg, IMessage Respond)
  {
   Console.Write("End Aop !") ;
  }
}

[AopProxyAttribute(typeof(AopControlProxyFactory))] //将自己委托给AOP代理AopControlProxy
public class Example : ContextBoundObject//放到特定的上下文中，该上下文外部才会得到该对象的透明代理
{
  private string name ;
  public Example(string a)
  {
   this.name = a ;
  }


  [MethodAopSwitcherAttribute(true)]
  public void say_hello()
  {
   Console.WriteLine("hello ! " + name ) ;
  }

  public void sayByeBye()
  {
   Console.WriteLine("Bye ! " + name ) ;
  }
}
