caSTLe-windsor - 温莎城堡和 IPrincipal

Question

是否可以使用 CaSTLe Windsor 将 IPrincipal 注入(inject)到我的 asp.net mvc Controller 中。本文作者Scott Hanselman评论中有代码可以用结构图来做，但我不知道如何用 CaSTLe 来做。

更新:

这是我最终为我的 Controller 工厂所做的。请注意，大部分代码来自 Steve Sanderson 的 Pro ASP.NET MVC 书籍，并添加了以下答案中的代码。

public class WindsorControllerFactory : DefaultControllerFactory
{
    readonly WindsorContainer _container;
    // The constructor:
    // 1. Sets up a new IoC container
    // 2. Registers all components specified in web.config
    // 3. Registers IPrincipal
    // 4. Registers all controller types as components
    public WindsorControllerFactory()
    {
        // Instantiate a container, taking configuration from web.config
        _container = new WindsorContainer(
        new XmlInterpreter(new ConfigResource("castle"))
        );

        _container.AddFacility<FactorySupportFacility>();
        _container.Register(Component.For<IPrincipal>()
          .LifeStyle.PerWebRequest
          .UsingFactoryMethod(() => HttpContext.Current.User));

        // Also register all the controller types as transient
        var controllerTypes = from t in Assembly.GetExecutingAssembly().GetTypes()
                              where typeof(IController).IsAssignableFrom(t)
                              select t;

        foreach (var t in controllerTypes)
            _container.AddComponentLifeStyle(t.FullName, t, LifestyleType.Transient);
    }

    // Constructs the controller instance needed to service each request
    protected override IController GetControllerInstance(Type controllerType)
    {
        return (IController)_container.Resolve(controllerType);
    }        
}

Answer 1

如果您使用的是 Windsor 2.0，则无需修改 ControllerFactory:

var container = new WindsorContainer();
container.AddFacility<FactorySupportFacility>();
container.Register(Component.For<IPrincipal>()
  .LifeStyle.PerWebRequest
  .UsingFactoryMethod(() => HttpContext.Current.User));
// your component registrations...

这只是工厂设施配置的包装器。如果您使用的是以前的版本 (RC3)，您可以 configure this with XML too .
