我如何告诉Windsor向所有实现IMustBeIntercepted的已注册组件添加拦截器 [英] How do I tell Windsor to add an Interceptor to all components registered that implement IMustBeIntercepted

问题描述

如果我在温莎注册了多个组件。

If I registered several components with Windsor.

IAnimal提供BigAnimal
IPerson提供SmellyPerson
IWhale提供BlueWhale

IAnimal provides BigAnimal IPerson provides SmellyPerson IWhale provides BlueWhale

等。相当标准的组件注册

etc.. pretty standard component registeration

以上所有类型均实现IMustBeIntercepted，如何告诉容器向所有类型添加拦截器，实现IMustBeImplemented，以便在调用Resolve时返回一个BigAnimal，该BigAnimal具有匹配的定义的拦截器。我知道我可以为每个人做到这一点，但是我要避免使用它的额外XML配置或程序化配置

all the above types implement IMustBeIntercepted, how do I tell the container add an interceptor to all types that implement IMustBeImplemented so that when Resolve is called it is returned a BigAnimal with an interceptor as defined since it matches. I know I can do this for each one but its extra XML config or programatic config which I want to avoid

推荐答案

只需创建一个这样的界面：

Simply create an interface like this:

public interface IMustBeIntercepted {}

以及类似的设施：

public class InterceptionFacility : AbstractFacility {
    protected override void Init() {
        Kernel.ComponentRegistered += new Castle.MicroKernel.ComponentDataDelegate(Kernel_ComponentRegistered);
    }

    void Kernel_ComponentRegistered(string key, Castle.MicroKernel.IHandler handler) {
        if(typeof(IMustBeIntercepted).IsAssignableFrom(handler.ComponentModel.Implementation)) {
            handler.ComponentModel.Interceptors.Add(new InterceptorReference(typeof(TestInterceptor)));
        }
    }
}

然后将设施注册到使用< facility> 标签的容器。现在，所有实现 IMustBeIntercepted 的组件都将被拦截器 TestInterceptor 拦截。

Then register the facility to the container using the <facility> tag. Now all components that implements IMustBeIntercepted will be intercepted by the interceptor TestInterceptor.
