注册接口使用StructureMap和Autofac等Ioc容器

时间紧张，先记一笔，后续优化与完善。

    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。

今天阳光很好，坐在窗前，看窗外如此晴朗的天感觉特别舒心，雨过天晴后的世界总给人一种明媚，仿佛阳光照耀在“心田”上空，让前些天被风雨践踏的花朵重新得到爱的关怀，重现生命的活力！

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。

    

    

文章结束给大家分享下程序员的一些笑话语录： 自行车
一个程序员骑着一个很漂亮的自行车到了公司，另一个程序员看到了他，问 到，“你是从哪搞到的这么漂亮的车的？”
骑车的那个程序员说， “我刚从那边过来， 有一个漂亮的姑娘骑着这个车过来， 并停在我跟前，把衣服全脱了，然后对我说，‘你想要什么都可以’”。
另一个程序员马上说到， “你绝对做了一个正确的选择， 因为那姑娘的衣服你 并不一定穿得了”。
