autofac的拦截器

1.定义基础类

public interface DBPeople
    {
        void Say();
    }
    public class Child : DBPeople
    {
        public void Say()
        {
            Console.WriteLine("你好");
        }
    }

2注册并添加拦截器

 var builder = new ContainerBuilder();
            builder.RegisterType<ActionInterceptor>();//注册拦截器
            // 2第二种方法
            //注册Child并为其添加拦截器
            builder.RegisterType<Child>().As<DBPeople>().InterceptedBy(typeof(ActionInterceptor)).EnableInterfaceInterceptors();

            var container = builder.Build();
            var child = container.Resolve<DBPeople>();
            child.Say();
            Console.ReadKey();

3实现效果

 

 需要通过nuget安装两个Package：Autofac、Autofac.Extras.DynamicProxy

但是我如果写成从抽象类继承就会报错------先记下来吧

public abstract class DBPeople
    {
        public  abstract void Say();
    }
    public class Child : DBPeople
    {
        public override void Say()
        {
            Console.WriteLine("你好");
        }
    }
