Signalr Castle Windsor在信号器集线器中抛出“范围缓存已被处置”

我们正在开发一个基于

.NET 4.5.1 MVC 5.2.2 奥温 WebApi 2.2 信号机2.2.0 温莎城堡3.3.0 Wcf集成设施3.3.0 为了解析控制器，我们使用ControllerFactory类，该类在以下页面中进行了描述：

为了解决依赖关系，我们使用WindsorDependencyResolver类：

public class WindsorDependencyResolver : IDependencyResolver
{
    public IWindsorContainer Container { get; private set; }

    public WindsorDependencyResolver(IWindsorContainer windsorContainer)
    {
        Container = windsorContainer;
    }

    public IDependencyScope BeginScope()
    {
        return new WindsorDependencyScope(this.Container);
    }

    public object GetService(Type serviceType)
    {
        return this.Container.Kernel.HasComponent(serviceType) ? this.Container.Resolve(serviceType) : null;
    }

    public IEnumerable<object> GetServices(Type serviceType)
    {
        return this.Container.ResolveAll(serviceType).Cast<object>().ToArray();
    }

    public void Dispose()
    {
    }
}

public class WindsorDependencyScope : IDependencyScope
{
    public IWindsorContainer Container { get; set; }
    public IDisposable Scope { get; set; }

    public WindsorDependencyScope(IWindsorContainer container)
    {
        this.Container = container;
        this.Scope = container.BeginScope();
    }

    public object GetService(Type serviceType)
    {
        return this.Container.Kernel.HasComponent(serviceType) ? this.Container.Resolve(serviceType) : null;
    }

    public IEnumerable<object> GetServices(Type serviceType)
    {
        return this.Container.ResolveAll(serviceType).Cast<object>().ToArray();
    }

    public void Dispose()
    {
        this.Scope.Dispose();
    }
}

所有控制器、wcf服务客户端和拦截器（日志记录类除外）都在项目中向Lifestyle PerWebRequest注册。然而，我们用于日志记录的类是单例的

下面的Web.config中有一个设置：

<system.webServer>
    <modules runAllManagedModulesForAllRequests="true">
        ...
        <add name="PerRequestLifestyle" type="Castle.MicroKernel.Lifestyle.PerWebRequestLifestyleModule, Castle.Windsor" />
        ...
    </modules>
</system.webServer>

我可以在调试器窗口中调用Container.Resolve方法之前看到HttpContext。顺便说一下，我可以解析单例日志类

有趣的是，我的队友没有任何例外。主要区别在于我们的操作系统版本。我在Windows8.1中运行代码，我的队友在Windows7中运行代码

我们只在信号集线器上得到这个例外。我们在其他任何地方都没有例外。我们如何解决这个问题？

我在Startup类中使用ServiceLocator来解析IDependencyResolver。它看起来像：

internal class Startup
{
    public void Configuration(IAppBuilder appBuilder)
    {
        var config = new HttpConfiguration();
        config.Routes.MapHttpRoute("ActionApi", "{controller}/{action}/{id}", new {id = RouteParameter.Optional});

        config.DependencyResolver = ServiceLocator.Instance.Resolve<IDependencyResolver>();

        appBuilder.UseWebApi(config);
    }
}

也许这有帮助
