asp.net - CaSTLe Windsor 3 跨多个 Web 请求持久化 PerWebRequest 对象

Question

我有一个 MVC 4 项目，正在尝试将一个 PerWebRequest 对象注入(inject)到我的 Controller 中。然而，对象似乎没有在多个请求中重新创建

 private static IWindsorContainer InitializeWindsor()
    {
        var container = new WindsorContainer().Install(FromAssembly.This());

        // Add Factory facility
        container.AddFacility<TypedFactoryFacility>();

        // Register all controllers from this assembly
        foreach (var assembly in AppDomain.CurrentDomain.GetAssemblies())
        {
            container.Register(
                AllTypes.FromAssembly(assembly).BasedOn<Controller>().Configure(c => c.LifestyleTransient())
                );
        }

        // Register HTTP Handlers
        container.Register(Component.For<HttpRequestBase>().LifeStyle.PerWebRequest.UsingFactoryMethod(() => new HttpRequestWrapper(HttpContext.Current.Request)));
        container.Register(Component.For<HttpContextBase>().LifeStyle.PerWebRequest.UsingFactoryMethod(() => new HttpContextWrapper(HttpContext.Current)));


        // Register components
        container.Register(Component.For<PerWebRequestObject>().LifeStyle.PerWebRequest);
}

这是我的 PerWebRequestObject:

public class PerWebRequestObject
{
    public DateTime DateCreated { get; set; }

    public PerWebRequestObject()
    {
        DateCreated = DateTime.UtcNow;
        Debug.WriteLine("Created: " + DateCreated.ToLongTimeString());
    }
}

这是我的测试 Controller :

public class TestController : BaseController
{
    public PerWebRequestObject pwrObject { get; set; }

    public ActionResult Test()
    {
        Debug.WriteLine(pwrObject.DateCreated.ToLongTimeString());
        return new ContentResult();
    }
}

为什么这不起作用？请注意，我正在使用 WindsorControllerFactory 并像这样释放 Controller :

    public override void ReleaseController(IController controller)
    {
        var disposableController = controller as IDisposable;
        if (disposableController != null)
            disposableController.Dispose();

        _windsorContainer.Release(controller);
    }

两件事:

• 您怎么知道对象的生命周期不正确(没有跨网络请求重新创建)？

一个可能的解释是你的依赖看起来像这样:

Controller --> 单例 --> 你的 per-web-request-component

这是生活方式的不匹配，这可以解释您所看到的行为

• 不要丢弃 Controller 。这是容器的工作。
