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。

一位程序员去海边游泳，由于水性不佳，游不回岸了，于是他挥着手臂，大声求.救：“F1，F1！”
