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。
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”。
