温莎城堡：UsingFactoryMethod无法实例化，出现奇怪的错误 [英] Castle Windsor: UsingFactoryMethod can't instantiate with a weird error

问题描述

当我使用此注册时：

container.Register(
    Component
        .For<IFooFactory>()
        .ImplementedBy<FooFactory>(),
    Component
        .For<IFoo>()
        .UsingFactoryMethod(kernel => kernel.Resolve<IFooFactory>().CreateFoo())
);

我收到此异常：

Castle.MicroKernel.ComponentRegistrationException：类型MyNamespace.IFoo是抽象的。
因此，不可能将其实例化为MyNamespace.IFoo服务的实现。

Castle.MicroKernel.ComponentRegistrationException: Type MyNamespace.IFoo is abstract. As such, it is not possible to instansiate it as implementation of MyNamespace.IFoo service

我不确定问题是什么。但是堆栈跟踪显示，在'DefaultComponentActivator.CreateInstance（）'中，以下条件成功，然后引发错误：

I'm not really sure what the problem is. But the stack trace shows that in 'DefaultComponentActivator.CreateInstance()', the following condition succeeds and then the error is thrown:

if (createProxy == false && Model.Implementation.IsAbstract)

我是否需要代理这里的某种？
注册错误吗？

Do I need a proxy of some sort here? Is the registration wrong?

推荐答案

从消息看来，您尚未注册 IFooFactory 。

From the message it seems you haven't registered the IFooFactory.

还需要添加对factory方法的支持。只需在注册之前调用此命令即可。

Also You need to add support for the factory method. Just call this before you doing the registration:

container.AddFacility<Castle.Facilities.FactorySupport.FactorySupportFacility>();
