var builder = new ContainerBuilder();

var assemblies = new DirectoryInfo(
AppDomain.CurrentDomain.BaseDirectory)
.GetFiles("ServiceLeyer.dll")

//有拦截器

//无拦截器
builder1.RegisterAssemblyTypes(assemblies).As<ICategoryService>();

builder1.RegisterType<CallLog>();

builder1.Update(container);

//SingleInstance()单例使用。

//动态更新容器里的对象。

var builder1 = new ContainerBuilder();
builder1.RegisterType<CategoryService>().As <ICategoryService>()
.EnableClassInterceptors()
.InterceptedBy(typeof(CallLog));
builder1.Update(container);

//MVC注入
var builder = new ContainerBuilder();

// Register your MVC controllers.
builder.RegisterControllers(typeof(MvcApplication).Assembly);

// OPTIONAL: Register model binders that require DI.
builder.RegisterModelBinders(Assembly.GetExecutingAssembly());
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));
