使用Castle Windsor注入到CustomAttribute中的依赖关系 [英] Injecting dependency into CustomAttribute using Castle Windsor

问题描述

我在ASP.Net MVC应用程序中实现了一个自定义ActionFilter来授权用户。我使用CastleWindsor为所有控制器提供依赖注入，如下所示：

  protected virtual IWindsorContainer InitializeServiceLocator（）
 {
 IWindsorContainer container = new WindsorContainer（）; 
 ControllerBuilder.Current.SetControllerFactory（new WindsorControllerFactory（container））; 
 
 container.RegisterControllers（typeof（HomeController）.Assembly）; 
 ComponentRegistrar.AddComponentsTo（container）; 
 
 ServiceLocator.SetLocatorProvider（（）=> new WindsorServiceLocator（container））; 
 
返回容器; 
} 
  

在我的CustomAttribute中，我需要一个由我的所有控制器使用的依赖项，但是我无法在属性中使用基于构造函数的注入。

那么这里最干净的方法是什么？如何提供依赖关系？

解决方案

确定 - 这似乎是使用ASP MVC和Castle Windsor将数据库注入验证属性已被回答。

另外如何使用Windsor将依赖项注入到ActionFilterAttributes中。

阅读完上述内容后，引用的文章 - 对我来说，关键是 http://weblogs.asp.net/psteele/archive/2009/11/04/using-windsor-to-inject-dependencies-into-asp-net-mvc- actionfilters.aspx 为任何其他人感兴趣。

In my ASP.Net MVC application I have implemented a Custom ActionFilter to Authorize users.

I use CastleWindsor to provide dependency injection into all of the controllers as follows:

  protected virtual IWindsorContainer InitializeServiceLocator()
    {
        IWindsorContainer container = new WindsorContainer();
        ControllerBuilder.Current.SetControllerFactory(new WindsorControllerFactory(container));

        container.RegisterControllers(typeof(HomeController).Assembly);
        ComponentRegistrar.AddComponentsTo(container);

        ServiceLocator.SetLocatorProvider(() => new WindsorServiceLocator(container));

        return container;
    }

Within my CustomAttribute, I need a dependency that is used by all of my controllers, however I am unable to user Constructor based injection in an attribute.

So what's the cleanest way out here? How can I provide the dependency?

解决方案

OK - this seems to be a duplicate of Database injection into a validation attribute with ASP MVC and Castle Windsor which has been answered.

Also How do I use Windsor to inject dependencies into ActionFilterAttributes.

Having read through the above, and the referenced articles - the key one for me is http://weblogs.asp.net/psteele/archive/2009/11/04/using-windsor-to-inject-dependencies-into-asp-net-mvc-actionfilters.aspx for anyone else who is interested.
