泛型的Autofac拦截配置

Question

I'm trying to do some sort of interception by using Autofac. Currently I've some bll objects configured:

updater.RegisterGeneric(typeof(BaseBll<>))
            .AsImplementedInterfaces()
            .InstancePerRequest()
            .PropertiesAutowired(PropertyWiringOptions.AllowCircularDependencies)
            .InterceptedBy(typeof(ActivityLogger));
updater.Register(c => new ActivityLogger());

I put Interception attribute on one of the classes:

[Intercept(typeof(ActivityLogger))]
public class MyClassBll : BaseBll<TModel>, IMyClassBll

Unfortunately, the Intercept method is not called when calling some methods from MyClassBll. If you have any ideas, how this might be fixed, please let me know.

For now I've found temp workaround:

updater.RegisterType<MyClassBll>().As<IMyClassBll>().EnableInterfaceInterceptors();

Answer 1

似乎Autofac的属性注入存在一个错误，将其更改为构造函数注入即可解决该问题。

Answer 2

You forgot to include .EnableInterfaceInterceptors() or .EnableClassInterceptors() before the .InterceptedBy(). Take a look here: https://autofaccn.readthedocs.io/en/latest/advanced/interceptors.html

[UPDATE]

As requested, I provided a code sample, based on the posted code:

updater.RegisterGeneric(typeof(BaseBll<>))
  .AsImplementedInterfaces()
  .InstancePerRequest()
  .PropertiesAutowired(PropertyWiringOptions.AllowCircularDependencies)
  .EnableInterfaceInterceptors()
  .InterceptedBy(typeof(ActivityLogger));
