注册接口使用StructureMap和Autofac等Ioc容器注册接口
本文笔者在广东游玩的时候突然想到的...今天就有想写几篇关于注册接口的文章,所以回家到之后就奋笔疾书的写出来发表了
1、StructureMap应用
StructureMap是通过定义一个StructureMapControllerFactory替换默许的DefaultControllerFactory,在Application_Start行进接口的注册。体具的应用网上已经有很多程教,这里就不多做绍介了。在这里要讲的是应用StructureMap做ico器容时HandleError性属会不起作用,据网上说可以修改Global件文中的RegisterGlobalFilters方法,但是总觉得用上去非常不爽,有些mvc有的特性用不了了,可见StructureMap的侵入性是比大较的。同时StructureMap不持支Filter Attribute注入,只能通过态静工厂实当初Filter Attribute中应用接口,如写重AuthorizeAttribute授权性属:
/// <summary> /// 写重授权机制 /// </summary> public class UserAuthorizeAttribute : AuthorizeAttribute { private readonly ILocalAuthenticationService _authenticationService = AuthenticationFactory.GetLocalAuthenticationService(); protected override bool AuthorizeCore(System.Web.HttpContextBase httpContext) { if (httpContext == null) throw new ArgumentNullException("httpContext"); var cookie = httpContext.Request.Cookies[FormsAuthentication.FormsCookieName]; if (cookie == null) return false; if (string.IsNullOrEmpty(cookie["username"])) return false; if (string.IsNullOrEmpty(cookie["usertoken"])) return false; if (!_authenticationService.ValidateAuthenticationToken(cookie["username"], cookie["usertoken"])) return false; return true; } }
我们须要建一个工厂才可以在AuthorizeAttribute中应用接口。AuthenticationFactory如下
public class AuthenticationFactory { private static ILocalAuthenticationService _authenticationService; public static void InitializeAuthenticationFactory( ILocalAuthenticationService authenticationService) { _authenticationService = authenticationService; } public static ILocalAuthenticationService GetLocalAuthenticationService() { return _authenticationService; } }
同时还要在Application_Start对接口行进初始化。
protected void Application_Start() { AreaRegistration.RegisterAllAreas(); BootStrapper.ConfigureDependencies(); AuthenticationFactory.InitializeAuthenticationFactory (ObjectFactory.GetInstance<ILocalAuthenticationService>()); ApplicationSettingsFactory.InitializeApplicationSettingsFactory (ObjectFactory.GetInstance<IApplicationSettings>()); LoggingFactory.InitializeLogFactory(ObjectFactory.GetInstance<ILogger>()); EmailServiceFactory.InitializeEmailServiceFactory (ObjectFactory.GetInstance<IEmailService>()); ObjectFactory.GetInstance<ILogger>().Log("程序开始了"); ControllerBuilder.Current.SetControllerFactory(new IoCControllerFactory()); //移除过剩的视图引擎 ViewEngines.Engines.Clear(); ViewEngines.Engines.Add(new RazorViewEngine()); RegisterGlobalFilters(GlobalFilters.Filters); RegisterRoutes(RouteTable.Routes); }
2、Autofac应用
对相StructureMap说来,Autofac的浸入性要小得多。请考参文章http://www.cnblogs.com/shanyou/archive/2010/02/07/1665451.html。他不会像StructureMap会致导mvc特性失效。同时持支性属注入。
protected void Application_Start() { AreaRegistration.RegisterAllAreas(); var builder = new ContainerBuilder(); //注册控制器 builder.RegisterControllers(Assembly.GetExecutingAssembly()); //注册Filter Attribute builder.RegisterFilterProvider(); //注册各种 ContainerManager.SetupResolveRules(builder); var container = builder.Build(); DependencyResolver.SetResolver(new AutofacDependencyResolver(container)); //初始化各种工厂 AuthenticationFactory.InitializeAuthenticationFactory(container.Resolve<ILocalAuthenticationService>()); ApplicationSettingsFactory.InitializeApplicationSettingsFactory(container.Resolve<IApplicationSettings>()); EmailServiceFactory.InitializeEmailServiceFactory(container.Resolve<IEmailService>()); LoggingFactory.InitializeLogFactory(container.Resolve<ILogger>()); container.Resolve<ILogger>().Log("哇!程序开始了!"); //移除过剩的视图引擎 ViewEngines.Engines.Clear(); ViewEngines.Engines.Add(new RazorViewEngine()); RegisterGlobalFilters(GlobalFilters.Filters); RegisterRoutes(RouteTable.Routes); }
Filter Attribute注入
/// <summary> /// 写重授权机制 /// </summary> public class UserAuthorizeAttribute : AuthorizeAttribute { //private readonly ILocalAuthenticationService _authenticationService = // AuthenticationFactory.GetLocalAuthenticationService(); public ILocalAuthenticationService _authenticationService { get; set; } protected override bool AuthorizeCore(System.Web.HttpContextBase httpContext) { if (httpContext == null) throw new ArgumentNullException("httpContext"); var cookie = httpContext.Request.Cookies[FormsAuthentication.FormsCookieName]; if (cookie == null) return false; if (string.IsNullOrEmpty(cookie["username"])) return false; if (string.IsNullOrEmpty(cookie["usertoken"])) return false; if (!_authenticationService.ValidateAuthenticationToken(cookie["username"], cookie["usertoken"])) return false; return true; } }
ContainerManager类中注册各种接口
public class ContainerManager { public static void SetupResolveRules(ContainerBuilder builder) { builder.RegisterType<UserRepository>().As<IUserRepository>(); builder.RegisterType<UserGroupRepository>().As<IUserGroupRepository>(); builder.RegisterType<SqlServrUnitOfWork>().As<IUnitOfWork>(); builder.RegisterType<UserService>().As<IUserService>(); builder.RegisterType<UserGroupService>().As<IUserGroupService>(); builder.RegisterType<EncryptionService>().As<IEncryptionService>(); builder.RegisterType<JwayAuthenticationService>().As<ILocalAuthenticationService>(); builder.RegisterType<SMTPService>().As<IEmailService>(); builder.RegisterType<Log4NetAdapter>().As<ILogger>(); builder.RegisterType<WebConfigApplicationSettings>().As<IApplicationSettings>(); } }
Autofac的其他注册式形请考参http://code.google.com/p/autofac/wiki/MvcIntegration3
随着Repository模式的普遍应用,Ioc器容越来遭到大广开发者的爱好。
