使用StructureMap DynamicProxyInterceptor时，如何从容器解析IInterceptionBehavior实例? [英] How do you resolve instances of IInterceptionBehavior from the container when using StructureMap DynamicProxyInterceptor?

问题描述

我正在从Unity迁移到StructureMap.我已经利用了Unity的InterceptionBehavior.

I'm migrating from Unity to StructureMap. I've made some use of Unity's InterceptionBehavior.

我以为我可以将其切换为使用StructureMap .InterceptWith和DynamicProxyInterceptor，但是我的拦截器具有依赖性，因此我无法弄清楚如何使用StructureMap构成拦截器.

I thought I could switch that to use StructureMap .InterceptWith and the DynamicProxyInterceptor but my interceptors have dependencies and I can't work out how to compose the interceptors using StructureMap.

var container = new Container(x =>
        {
            x.For<IMathService>().Use<MathService>()
                .InterceptWith(new DynamicProxyInterceptor<IMathService>(new IInterceptionBehavior[]
                {
                    // I WANT TO COMPOSE THESE INTERCEPTORS
                    new NegatingInterceptor(), 
                    new CachingInterceptor()
                }));
        });

目前，我唯一能想到的解决方案是从静态IoC类公开我的IContainer，并在拦截器中手动解析我的依赖项.

At the moment the only thing I can think that might be a solution is to expose my IContainer from the static IoC class and resolve my dependencies manually in my interceptor.

最终，我可能会解决用装饰器替换动态代理的问题，但是我还没有达到那个阶段.我只想尽快使它重新启动并运行，这样我就可以证明其他更改都已成功，然后再开始进行其他更改.

Eventually I'll probably get around to replacing my dynamic proxies with decorators but I'm not quite at that stage yet. I just want to get it up and running again as soon as possible so I can prove the other changes are all successful before I start to make additional changes.

推荐答案

好吧，我是个白痴，您只是将类型数组而不是实例传递给DynamicProxyInterceptor构造函数

Okay, I'm an idiot, you just pass an array of types instead of instances to the DynamicProxyInterceptor constructor

var container = new Container(x =>
    {
        x.For<IMathService>().Use<MathService>()
            .InterceptWith(new DynamicProxyInterceptor<IMathService>(
            new Type[]
            {
                // I WANT TO COMPOSE THESE INTERCEPTORS
                typeof(NegatingInterceptor), 
                typeof(CachingInterceptor)
            }));
    });
