对于这个容器注入，个人也不是很熟悉，很多还不懂，只会基本的操作，几天把它记录下来，相信不久的自己会更上一层楼

下面记录下应用的流程

步骤：

1.添加应用

2.重写工厂（这里讲的是常用的构造方法注入方式）

 1 public class CreateAutofacFactory : DefaultControllerFactory 2     { 3         public override IController CreateController(RequestContext requestContext, string controllerName) 4         { 5             //获取容器 6             IContainer ic = CreateControllers.CreateController().Icontainer; 7             //获取控制器类型 8             Type t = this.GetControllerType(requestContext, controllerName); 9             //从容器中解析出对象10             return ic.Resolve(t) as IController;11         }12     }

 1 public class CreateControllers 2     { 3         PRivate CreateControllers() { } 4         private static CreateControllers createController; 5         public static CreateControllers CreateController() 6         { 7             if (createController == null) 8                 createController = new CreateControllers(); 9             return createController;10         }11         private IContainer iContainer { get; set; }12         public IContainer Icontainer13         {14             get 15             {16                 if (iContainer == null)17                 {18                     ContainerBuilder cb = new ContainerBuilder();19                     //用代码注册类型20                     //cb.RegisterType<StudentDao>().As<IStudentDao>();21                     //cb.RegisterType<StudentManager>().As<IStudentManager>();22                     //cb.RegisterType<HomeController>();23 24                     //从配置文件注册类型25                     cb.RegisterModule(new ConfigurationSettingsReader("autofac"));26                     iContainer = cb.Build();//创建容器27                 }28                 return iContainer;29             }30         }31     }

3.启动（更换）工厂

 1 public class Mvcapplication : System.Web.HttpApplication 2     { 3         protected void Application_Start() 4         { 5             AreaRegistration.RegisterAllAreas(); 6  7             WebApiConfig.Register(GlobalConfiguration.Configuration); 8             FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); 9             RouteConfig.RegisterRoutes(RouteTable.Routes);10             BundleConfig.RegisterBundles(BundleTable.Bundles);11 12             //换ControllerFactory(服务器一启动就更换工厂)13             ControllerBuilder.Current.SetControllerFactory(new CreateAutofacFactory());14         }15     }

4.添加配置文件

 1 <configSections> 2     <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 --> 3     <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" /> 4    5     <!--在配置文件中添加配置节点 name是配置节点的标签名  6         type是读取配置节点内容的类 格式：命名空间名.类名，程序集名--> 7     <section name="autofac" type="Autofac.Configuration.SectionHandler, Autofac.Configuration"/> 8    9   </configSections>10 11 <autofac>12     <components>13         <component type="Winning.Tjgi.Backstage3G.UI.Controllers.HomeController,Winning.Tjgi.Backstage3G.UI"14                />15 <component16              type="test.Dal.UserDao,test.Dal"17              service="test.IDal.IUserDao,test.IDal"/>18 <component19               type="test.Bll.UserManager,test.Bll"20               service="test.IBll.IUserManager,test.IBll" />21 </components>22   </autofac>

5.构造函数

1         IUserManager uMan = null;2         public HomeController(IUserManager uMan)3         {4             this.uMan = uMan;5         }    

五步走起，如果过程出错的话基本上都是配置文件配置出错，还有就是经常忘记更新dll类库，在这里要建议下把类库的输出路径改成到UI项目里，经常动手才会记忆深刻，一直在努力中，希望能走出自己的道路，虽然脆弱，却不退缩。
