MVC 2 Beta DefaultControllerFactory 带区域 [英] MVC 2 Beta DefaultControllerFactory with Areas

问题描述

为什么默认工厂不会返回控制器的全名(带命名空间)?我正在使用服务定位器和 autofac.

Why default factory WON'T return full name of the controllers (with namespaces)? I'm using Service Locator and autofac.

using System.Web.Mvc;

using Microsoft.Practices.ServiceLocation;

namespace Application.Core.MVC
{

        public override IController CreateController(System.Web.Routing.RequestContext requestContext, string **controllerName**)
        {
            return ServiceLocator.Current.GetInstance<IController>(controllerName);
        }
}

我有两个家庭控制器(一个在博客区域下)

I had two home controllers (one under area Blog)

http://localhost/Home

http://localhost/Blog/Home

controllerName 在上面的代码中只返回Home"而没有完全限定的名称.当我尝试为依赖项注入注册控制器的名称时，这会产生问题.这是我现在根据这种情况注册控制器的方法.即使这样也无一例外地调出页面.但是当我访问 http://localhost/Home 时，两个控制器都会调用.

controllerName return only "Home" without full qualified name for both in above code. This creates a problem when I try to regiser controllers' names for dependency injection. Here is how I register controllers right now according to this situation. Even this brings up the pages without exception. But When I access http://localhost/Home, both controllers invoked regardlessly.

   foreach (var tp in currentAssemblyControllersTypes)
                    builder.Register(tp).FactoryScoped().Named(tp.Name.Replace("Controller", ""));

有人可以帮忙吗?谢谢.

Anyone can help?Thanks.

推荐答案

DefaultControllerFactory.CreateController() 方法负责为给定的请求返回一个控制器.controllerName 参数只是路由的 {controller} 部分.CreateController() 的工作 - 而不是它的调用者 - 根据 URL 中指定的控制器名称找出正确的类型.

The DefaultControllerFactory.CreateController() method is responsible for returning a controller for the given request. The controllerName parameter is just the {controller} part of the route. It's CreateController()'s job - not its caller's - to figure out the proper type given the controller name as specified in the URL.

为了使这更容易，DefaultControllerFactory.CreateController() 委托给另外两个方法:GetControllerType() 和 GetControllerInstance().如果您想使用原始控制器解析逻辑(例如类型查找)但只是更改类型的实例化方式，请保持 CreateController() 和 GetControllerType() 方法不变，只需覆盖 GetControllerInstance().这已经处理了您正在复制的命名空间查找逻辑，并使您的代码更加简单.

To make this easier, DefaultControllerFactory.CreateController() delegates into two other methods: GetControllerType() and GetControllerInstance(). If you want to use the original controller resolution logic (e.g. type lookup) but just change how types are instantiated, leave the CreateController() and GetControllerType() methods as-is, and just override GetControllerInstance(). This already takes care of the namespace lookup logic you're duplicating and will make your code far simpler.
