MVC 2 Beta版DefaultControllerFactory与地区 [英] MVC 2 Beta DefaultControllerFactory with Areas

问题描述

为什么出厂默认的不会返回控制器（使用命名空间）的全称是什么？
我使用的服务定位和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);
        }
}

我有两个家控制器（一个下面积博客）

I had two home controllers (one under area Blog)

的http：//本地主机/家庭

的http：//本地主机/博客/主页

controllerName上面code仅返回家不完全合格的名称为。
当我尝试reactor进行注册控制器的名字依赖注入这就产生了一个问题。
这里是我现在根据这个情况登记控制器。即使这引起了无一例外的网页。但是，当我访问的http：//本地主机/主页，两个控制器regardlessly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", ""));

任何人都可以帮忙吗？谢谢。

Anyone can help?Thanks.

推荐答案

该DefaultControllerFactory.CreateController（）方法负责给定请求返回的控制器。该controllerName参数是路由的仅有的{控制器}一部分。它的 CreateController（）的的工作 - 而不是它的调用者的 - 找出给定为在URL中指定控制器名称的正确类型

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.

为使这更容易，DefaultControllerFactory.CreateController（）代表到其他两种方法：GetControllerType（）和GetControllerInstance（）。如果你想使用原来的控制器解决逻辑（例如型查找），但只是改变类型如何实例化，离开CreateController（）和GetControllerType（）方法原样，只是重写GetControllerInstance（）。这已经需要你复制名称空间查询逻辑的护理，将会让您code就简单得多了。

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.
