caSTLe-windsor - 温莎城堡 : UsingFactoryMethod can't instantiate with a weird error

Question

当我使用此注册时:

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

我得到这个异常(exception):

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

我不太确定问题是什么。但是堆栈跟踪显示，在“DefaultComponentActivator.CreateInstance()”中，以下条件成功，然后抛出错误:

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

我在这里需要某种代理吗？
是不是注册错了？

Answer 1

从消息看来您还没有注册 IFooFactory .

您还需要添加对工厂方法的支持。只需在进行注册之前调用它:

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