        AreaRegistration.RegisterAllAreas();
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);

        ContainerBuilder builder = new ContainerBuilder();
        Type baseType = typeof(IDependency);
        // 自动注册当前程序集
        //builder.RegisterAssemblyTypes(Assembly.GetExecutingAssembly()).AsImplementedInterfaces();
        // 注册当前程序集
        Assembly assemblies = Assembly.GetExecutingAssembly();
        builder.RegisterAssemblyTypes(assemblies)
        .Where(type => baseType.IsAssignableFrom(type) && !type.IsAbstract)
        .AsImplementedInterfaces().InstancePerLifetimeScope();//保证对象生命周期基于请求
        //注册引用的程序集
        //var assemblyList = BuildManager.GetReferencedAssemblies().Cast<Assembly>().Where(assembly => assembly.GetTypes().Any(type => type.GetInterfaces().Contains(baseType)));
        //var enumerable = assemblyList as Assembly[] ?? assemblyList.ToArray();
        //if (enumerable.Any())
        //{
        //    builder.RegisterAssemblyTypes(enumerable)
        //        .Where(type => type.GetInterfaces().Contains(baseType))
        //        .AsImplementedInterfaces().InstancePerLifetimeScope();
        //}
        //注册指定的程序集
        //自动注册了IStudentService、IUserService
        builder.RegisterAssemblyTypes(Assembly.Load("AppService"), Assembly.Load("AppService"))
        .Where(t => t.Name.EndsWith("Service"))
        .AsImplementedInterfaces();
        //一、Type注册服务
        builder.RegisterType<CourseService>().As<ICourseService>();
        builder.RegisterType<UserService>().AsSelf();// 注入类本身，等价于.As<UserService>();
        builder.RegisterType<ScoreManage>().AsImplementedInterfaces();//批量注册，等价于.As<IEnglishScoreManage>().As<IMathematicsScoreManage>();
        //二、Named注册服务
        //builder.RegisterType<ChineseScorePlusManage>().Named<IChineseScoreManage>(ChineseScoreEnum.ChineseScorePlus.ToString());// 一个接口与多个类型关联
        //builder.RegisterType<ChineseScoreManage>().Named<IChineseScoreManage>(ChineseScoreEnum.ChineseScore.ToString());// 一个接口与多个类型关联
        //三、Keyed注册服务
        builder.RegisterType<ChineseScorePlusManage>().Keyed<IChineseScoreManage>(ChineseScoreEnum.ChineseScorePlus);// 一个接口与多个类型关联
        builder.RegisterType<ChineseScoreManage>().Keyed<IChineseScoreManage>(ChineseScoreEnum.ChineseScore);// 一个接口与多个类型关联

        //泛型注册,可以通过容器返回List<T> 如:List<string>,List<int>等等
        //builder.RegisterGeneric(typeof(List<>)).As(typeof(IList<>)).InstancePerLifetimeScope();
        //生命周期
        //builder.RegisterType<StudentService>().As<IStudentService>().InstancePerLifetimeScope(); //基于线程或者请求的单例..就是一个请求 或者一个线程 共用一个
        //builder.RegisterType<StudentService>().As<IStudentService>().InstancePerDependency(); //服务对于每次请求都会返回单独的实例
        //builder.RegisterType<StudentService>().As<IStudentService>().SingleInstance(); //单例.. 整个项目公用一个
        //builder.RegisterType<StudentService>().As<IStudentService>().InstancePerRequest(); //针对MVC的,或者说是ASP.NET的..每个请求单例
        builder.RegisterType<ServiceGetter>().As<IServiceGetter>();//用于一个接口与多个类型关联
        builder.RegisterControllers(Assembly.GetExecutingAssembly()).PropertiesAutowired();//属性注入,未注册将出现“没有为该对象定义无参数的构造函数。”
        builder.RegisterType<TestDbContext>().As<IDbContext>().InstancePerLifetimeScope();
        builder.RegisterGeneric(typeof(EfRepository<>)).As(typeof(IRepository<>)).InstancePerLifetimeScope();//泛型注入
        //builder.RegisterFilterProvider(); //注入特性,特性里面要用到相关的服务
        IContainer container = builder.Build();
        DependencyResolver.SetResolver(new AutofacDependencyResolver(container));//生成容器并提供给MVC
    }
    protected void Application_BeginRequest()
    {
        if (Request.IsLocal)//这里是允许本地访问启动监控,可不写
        {
            MiniProfiler.Start();
        }
    }
    protected void Application_EndRequest()
