试图通过Steve Sandersons的MVC书 – 但是在创建WindsorControllerFactory时遇到了困难.看起来该方法已从MVC1更改为MVC2.这是我在尝试编译项目时遇到的错误:
‘WebUI.WindsorControllerFactory.GetControllerInstance(System.Type:找不到合适的方法来覆盖’.任何帮助都会受到赞赏 – 我无法超越这个!
这是代码 – 从书中转录:
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using Castle.Windsor; using Castle.Windsor.Configuration.Interpreters; using Castle.Core.Resource; using System.Reflection; using Castle.Core; using Castle.MicroKernel; namespace WebUI { public class WindsorControllerFactory : DefaultControllerFactory { WindsorContainer container; // The constructor: // 1. Sets up a new IoC container // 2. Registers all components specified in web.config // 3. Registers all controller types as components public WindsorControllerFactory() { // Instantiate a container,taking configuration from web.config container = new WindsorContainer( new XmlInterpreter(new ConfigResource("castle")) ); // Also register all the controller types as transient var controllerTypes = from t in Assembly.GetExecutingAssembly().GetTypes() where typeof(IController).IsAssignableFrom(t) select t; foreach (Type t in controllerTypes) container.AddComponentWithLifestyle(t.FullName,t,LifestyleType.Transient); } // Constructs the controller instance needed to service each request protected override IController GetControllerInstance(Type controllerType) { return (IController)container.Resolve(controllerType); } } }
问候,

解决方法
由于有关竞争条件的不幸错误,GetControllerInstance已从ASP.NET MVC 1.0更改为ASP.NET MVC 2.
ASP.NET MVC 1.0中的签名是:
protected virtual IController GetControllerInstance( Type controllerType);
在ASP.NET MVC 2中它是:
protected virtual IController GetControllerInstance( RequestContext requestContext,Type controllerType)
对于这种特殊情况,您似乎只需要将方法的签名更改为:
protected override IController GetControllerInstance( RequestContext requestContext,Type controllerType) { return (IController)container.Resolve(controllerType); }
潜在的竞争条件是RequestContext实例可以由多个同时请求共享,这将是一个主要的禁忌.幸运的是,似乎没有任何用户遇到过这个问题,但无论如何它在ASP.NET MVC 2中得到了修复.
