MVC Castle依赖注入实现代码
1、MVc 实现依赖注入
public class WindsorControllerFactory : DefaultControllerFactory { private readonly IKernel _kernel; public WindsorControllerFactory(IKernel kernel) { _kernel = kernel; } protected override IController GetControllerInstance(System.Web.Routing.RequestContext requestContext, System.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)_kernel.Resolve(controllerType); } public override void ReleaseController(IController controller) { _kernel.ReleaseComponent(controller); base.ReleaseController(controller); }
}
public class ControllerInstaller : IWindsorInstaller { public void Install(Castle.Windsor.IWindsorContainer container, Castle.MicroKernel.SubSystems.Configuration.IConfigurationStore store) { container.Register(Classes.FromThisAssembly() //在哪里找寻接口或类 .BasedOn<IController>() //实现IController接口 .If(Component.IsInSameNamespaceAs<HomeController>()) //与HomeController在同一个命名空间 .If(t => t.Name.EndsWith("Controller")) //以"Controller"结尾 .Configure(c => c.LifestylePerWebRequest()));//每次请求创建一个Controller实例 container.Register( Component.For<IUserDal>().ImplementedBy<UserDal>().LifestylePerWebRequest()); } }
Global.asax 文件进行注册
public class MvcApplication : System.Web.HttpApplication { private IWindsorContainer _container; protected void Application_Start() { AreaRegistration.RegisterAllAreas(); WebApiConfig.Register(GlobalConfiguration.Configuration); FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); RouteConfig.RegisterRoutes(RouteTable.Routes); //初始化一个IOC容器 _container = new WindsorContainer().Install(FromAssembly.This()); //完成IWindsorInstaller接口中的注册 ControllerBuilder.Current.SetControllerFactory(new WindsorControllerFactory(_container.Kernel)); } protected void Application_End() { _container.Dispose(); } }
2、web api 依赖注入实现
一、创建 WindsorActivator 继承 IHttpControllerActivator
public class WindsorCompositionRoot : IHttpControllerActivator { private readonly IWindsorContainer _container; public WindsorCompositionRoot(IWindsorContainer container) { _container = container; } public IHttpController Create(HttpRequestMessage request, HttpControllerDescriptor controllerDescriptor, Type controllerType) { var controller = (IHttpController)_container.Resolve(controllerType); request.RegisterForDispose( new Release(() => _container.Release(controller))); return controller; } private sealed class Release : IDisposable { private readonly Action _release; public Release(Action release) { _release = release; } public void Dispose() { _release(); } }
}
public class RepositoriesInstaller : IWindsorInstaller { public void Install(IWindsorContainer container, IConfigurationStore store) { container.Register( Component.For<ITitemService>().ImplementedBy<TitemService>().LifestylePerWebRequest()); } }
Global.asax 文件注册
public class WebApiApplication : System.Web.HttpApplication { private static IWindsorContainer _container; protected void Application_Start() { AreaRegistration.RegisterAllAreas(); //api 初始化 ConfigureWindsor(GlobalConfiguration.Configuration); WebApiConfig.Register(GlobalConfiguration.Configuration); FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); RouteConfig.RegisterRoutes(RouteTable.Routes); BundleConfig.RegisterBundles(BundleTable.Bundles); } public static void ConfigureWindsor(HttpConfiguration configuration) { _container = new WindsorContainer(); _container.Install(FromAssembly.This()); _container.Kernel.Resolver.AddSubResolver(new CollectionResolver(_container.Kernel, true));
RegisterControllerActivator(_container);
}
}
private static void RegisterControllerActivator(IWindsorContainer container) { GlobalConfiguration.Configuration.Services.Replace(typeof(IHttpControllerActivator), new WindsorCompositionRoot(container)); }
}
