Castle windsor快速入门

1.创建MVC项目，安装Castle Windsor

2.创建CastleWindsor文件夹

    在ASP.NET MVC中，每次请求，DefaultControllerFactory都会为我们创建controller实例，我们需要自定义一个派生自DefaultControllerFactory的类，让Castle Windsor帮我们生成controller实例。创建WindsorControllerFactory类，并集成子DeafaultControllerFactory

namespace CastleApp.CastleWindsor
{
    public class WindsorControllerFactory : DefaultControllerFactory
    {
        private readonly IKernel _ikernel;
        public WindsorControllerFactory(IKernel ikernel)
        {
            _ikernel = ikernel;
        }
        protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType)
        {
            if (controllerType == null)
            {
                throw new HttpException(404, string.Format("当前对{0}的请求不存在", requestContext.HttpContext.Request.Path));
            }
            return (IController)_ikernel.Resolve(controllerType);
        }
        public override void ReleaseController(IController controller)
        {
            _ikernel.ReleaseComponent(controller);
            base.ReleaseController(controller);
        }
    }
}

public class MvcApplication : System.Web.HttpApplication
    {
        public static IWindsorContainer _container;
        protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();
            RouteConfig.RegisterRoutes(RouteTable.Routes);

            MvcApplication.BootstrapContainer();
        }
        private static void BootstrapContainer()
        {
            _container = new WindsorContainer();
            _container.Install(FromAssembly.This());
            ControllerBuilder.Current.SetControllerFactory(new WindsorControllerFactory(_container.Kernel));
        }
        protected void Application_End()
        {
            _container.Dispose();
        }
    }

namespace CastleApp.CastleWindsor
{
    public class ControllerInstaller : IWindsorInstaller
    {
        public void Install(IWindsorContainer container, IConfigurationStore store)
        {
            container.Register(Classes.FromThisAssembly() //在哪里找寻接口或类
                .BasedOn<IController>() //实现IController接口
                .Configure(c => c.LifestylePerWebRequest()));//每次请求创建一个Controller实例

            container.Register(Component.For<IContactManager>().ImplementedBy<ContactManager>());
        }
    }
}

public class AboutController : Controller
    {
        private IContactManager contactManager;
        public AboutController(IContactManager contactManager)
        {
            this.contactManager = contactManager;
        }
        public ActionResult Index()
        {
            
            ViewBag.name= contactManager.ShowName("123");
            return View();
        }
    }
