asp.net-mvc - Ninject.Web.Common 抛出 ActivationException 试图将依赖项注入(inject) HttpApplicationInitializationHttpModule

Question

我什至不知道从哪里开始解决这个问题，但是在尝试运行我的 ASP.NET MVC 应用程序时遇到了异常。

这是我得到的错误:

[ActivationException: Error activating IntPtr

No matching bindings are available, and the type is not self-bindable. Activation path:

1. Injection of dependency IntPtr into parameter method of constructor of type Func{IKernel}
2. Injection of dependency Func{IKernel} into parameter lazyKernel of constructor of type HttpApplicationInitializationHttpModule
3. Request for IHttpModule

Suggestions:

1. Ensure that you have defined a binding for IntPtr.
2. If the binding was defined in a module, ensure that the module has been loaded into the kernel.
3. Ensure you have not accidentally created more than one kernel.
4. If you are using constructor arguments, ensure that the parameter name matches the constructors parameter name.
5. If you are using automatic module loading, ensure the search path and filters are correct.

堆栈跟踪如下:

这似乎不是每个人都会遇到的错误(至少，我的谷歌搜索没有发现任何有用的东西)，所以我认为我在做一些奇怪的事情，但我不知道从哪里开始调试它。

我应该提到我正在使用几个 Ninject 库(Ninject、Ninject.Web.Common、Ninject.MVC3 和 Ninject.FluentValidation)，它们都是 3.0.00-RC3 版本。我意识到如果我使用预发布库，所有的赌注都将失败，但我觉得我做错了什么，因为其他人似乎没有遇到同样的错误。

关于问题可能是什么或我应该从哪里开始寻找的任何想法？

Answer 1

您可以通过将这两个绑定(bind)添加到内核来解决此问题:

kernel.Bind<Func<IKernel>>().ToMethod(ctx => () => new Bootstrapper().Kernel);
kernel.Bind<IHttpModule>().To<HttpApplicationInitializationHttpModule>();
