    [AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, Inherited = true)]

    }

2.WebApiConfig中启用

public static void Register(HttpConfiguration config)
{
　　//启用监控接口执行时间
　　config.Filters.Add(new TimingActionFilter());

　　//默认路由
　　config.Routes.MapHttpRoute(
　　　　name: "DefaultApi",
　　　　routeTemplate: "api/{controller}/{id}",
　　　　defaults: new { id = RouteParameter.Optional }
　　);
}
