语言组织得不好，莫见怪，

这个是spring.net srping.web.mvc3的一个bug，他的SpringControllerFactory里面的

protected override IController GetControllerInstance 这个方法写得有问题，改正的应该是

protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType)
        {
            IController controllerInstance = null;
            if (controllerType != null)
            {
                IDictionary objectsOfType = ApplicationContext.GetObjectsOfType(controllerType);
                if (objectsOfType.Count > 0)
                {
                    controllerInstance = (IController)objectsOfType.Cast<DictionaryEntry>().First<DictionaryEntry>().Value;
                }
                else
                {
                    controllerInstance = base.GetControllerInstance(requestContext, controllerType);
                }
            }
            else // there should be if (contollerInstance == null)
            {
                controllerInstance = base.GetControllerInstance(requestContext, controllerType);
            }
            
            this.AddActionInvokerTo(controllerInstance);
            return controllerInstance;
        }
