使用Nuget添加Autofac.MVC的引用

启动项设置

 protected void Application_Start(){AreaRegistration.RegisterAllAreas();RouteConfig.RegisterRoutes(RouteTable.Routes);var builder = new ContainerBuilder();builder.RegisterType<BookService>().As<IBookService>();builder.RegisterType<Logger>().As<ILogger>();// Register your MVC controllers. (MvcApplication is the name of// the class in Global.asax.)builder.RegisterControllers(typeof(MvcApplication).Assembly);// OPTIONAL: Register model binders that require DI.builder.RegisterModelBinders(typeof(MvcApplication).Assembly);builder.RegisterModelBinderProvider();// OPTIONAL: Register web abstractions like HttpContextBase.builder.RegisterModule<AutofacWebTypesModule>();// OPTIONAL: Enable property injection in view pages.builder.RegisterSource(new ViewRegistrationSource());// OPTIONAL: Enable property injection into action filters.builder.RegisterFilterProvider();// Set the dependency resolver to be Autofac.var container = builder.Build();DependencyResolver.SetResolver(new AutofacDependencyResolver(container));}

注册Controller

注册当前程序集下的所有Controller
1. builder.RegisterControllers(typeof(MvcApplication).Assembly);

注册单个Controller

builder.RegisterType<HomeController>().InstancePerRequest();

注册ModelBinder

在启动项中注册ModelBinder
1. builder.RegisterModelBinders(typeof(MvcApplication).Assembly);
  builder.RegisterModelBinderProvider();
自定义ModelBinder并且设置ModelBinderTypeAttribute

    [ModelBinderType(typeof(Book))]public class BookModelBinder : IModelBinder{public ILogger logger;public BookModelBinder(ILogger logger){this.logger = logger;}public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext){HttpRequestBase request = controllerContext.HttpContext.Request;string title = request.Form.Get("Title");string BookID = request.Form.Get("BookID");string day = request.Form.Get("Day");string month = request.Form.Get("Month");string year = request.Form.Get("Year");return new Book { BookID=BookID, Title=title+":DI Test"+this.logger.Log("dsa")+request.Form.Get("HttpRequestBaseDI"), Date=year+"-"+month+"-"+day };}}

注册相关的Web Abstract Class

启动项设置

// OPTIONAL: Register web abstractions like HttpContextBase.
builder.RegisterModule<AutofacWebTypesModule>();
实例（在ModelBinder中使用HttpRequestBase）

   [ModelBinderType(typeof(Book))]public class BookModelBinder : IModelBinder{ILogger logger;HttpRequestBase request1;public BookModelBinder(ILogger logger, HttpRequestBase request){this.logger = logger;this.request1 = request;}public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext){HttpRequestBase request = controllerContext.HttpContext.Request;request = request1;string title = request.Form.Get("Title");string BookID = request.Form.Get("BookID");string day = request.Form.Get("Day");string month = request.Form.Get("Month");string year = request.Form.Get("Year");return new Book { BookID=BookID, Title=title+":DI Test"+this.logger.Log("dsa")+request.Form.Get("HttpRequestBaseDI"), Date=year+"-"+month+"-"+day };}}

在View层实现属性注入

启动项设置

builder.RegisterSource(new ViewRegistrationSource());

实现自定义的ViewPage
这里的例子使用的是一个强类型的View，所以实现了一个泛型ViewPage

public abstract class CustomViewPage<T> : WebViewPage<T>
    {
        public ILogger Logger { get; set; }
    }
View设置

@inherits MVC5Practices.Infrastructure.CustomViewPage<MVC5Practices.Infrastructure.Book>@{Layout = null;
}<!DOCTYPE html><html>
<head><meta name="viewport" content="width=device-width" /><title>ShowBook</title>
</head>
<body><div><h4>Book</h4><h5>@Logger.Log("dsa")</h5><hr /><dl class="dl-horizontal"><dt>@Html.DisplayNameFor(model => model.Title)</dt><dd>@Html.DisplayFor(model => model.Title)</dd><dt>@Html.DisplayNameFor(model => model.Date)</dt><dd>@Html.DisplayFor(model => model.Date)</dd></dl></div><p>@Html.ActionLink("Edit", "Edit", new { id = Model.BookID }) |@Html.ActionLink("Back to List", "Index")</p>
</body>
</html>

为ActionFilter启用属性设置

启动项设置

// OPTIONAL: Enable property injection into action filters.
builder.RegisterFilterProvider();
自定义Filter

 public class CustomActionFilter : ActionFilterAttribute{public ILogger Logger { get; set; }public override void OnActionExecuting(ActionExecutingContext filterContext){Logger.Log("OnActionExecuting");}}
