Unity mvc控制器''的单个实例不能用于处理多个请求

Question

我有一个MVC 5应用程序。我使用Unity作为我的DI。 在我的应用程序中，我有两个动作控制器：

• 主要行动
• 儿童行动

我的主要Action视图调用Html.RenderAction（＆＃34; ChildAction＆＃34;）。

我收到下一个错误：

A single instance of controller '' cannot be used to handle multiple requests. If a custom controller factory is in use, make sure that it creates a new instance of the controller for each request.

我尝试了很多解决方案，例如创建自定义＆＃34; UnityControllerFactory＆＃34;：

  public class UnityControllerFactory : DefaultControllerFactory
{
    IUnityContainer container;

    public UnityControllerFactory(IUnityContainer container)
    {
        this.container = container;
    }

    public override IController CreateController(RequestContext context, string controllerName)
    {
        Type type = GetControllerType(context, controllerName);

        if (type == null)
        {
            throw new InvalidOperationException(string.Format("Could not find a controller with the name {0}", controllerName));
        }



        return (IController)container.Resolve(type);
    }

    protected override IController GetControllerInstance(RequestContext reqContext, Type controllerType)
    {
        IController controller;
        if (controllerType == null)
            throw new HttpException(
                    404, String.Format(
                        "The controller for path '{0}' could not be found" +
        "or it does not implement IController.",
                    reqContext.HttpContext.Request.Path));

        if (!typeof(IController).IsAssignableFrom(controllerType))
            throw new ArgumentException(
                    string.Format(
                        "Type requested is not a controller: {0}",
                        controllerType.Name),
                        "controllerType");
        try
        {
            controller = container.Resolve(controllerType)
                            as IController;


        }
        catch (Exception ex)
        {
            throw new InvalidOperationException(String.Format(
                                    "Error resolving controller {0}",
                                    controllerType.Name), ex);
        }
        return controller;
    }
    public override void ReleaseController(IController controller)
    {
        container.Teardown(controller);
    }

使用＆＃34; TransientLifetimeManager＆＃34;：

注册控制器

container.RegisterType<TestController>(new TransientLifetimeManager());

没有任何效果。

我们将不胜感激。
