autofac的aop

1.安装包

autofac
Autofac.Extras.DynamicProxy -- 拦截器扩展

2.具体实现

     // 1第一种方法 [Intercept(typeof(ActionInterceptor))]
    class Program
    {
        static void Main(string[] args)
        {
            var buider = new ContainerBuilder();
            // 2第二种方法
            buider.RegisterType<Child>().As<DBPeople>()
            .EnableClassInterceptors()
            .InterceptedBy("action-interceptor");
            //.InterceptedBy(typeof(ActionInterceptor));
            //注册拦截器
            //buider.RegisterType<ActionInterceptor>();
            //第三种方法
            buider.RegisterType<ActionInterceptor>().Named<IInterceptor>("action-interceptor");
            
            var container = buider.Build();
            using (var scope = container.BeginLifetimeScope())
            {
                var child = scope.Resolve<DBPeople>();
                child.Say();
            }
            Console.ReadKey();
        }
    }
   public class ActionInterceptor : IInterceptor
   {
       public void Intercept(IInvocation invocation)
       {
           Console.WriteLine("say执行前-----------");
           invocation.Proceed();
           Console.WriteLine("say执行后-----------");
       }
   }
