Autofac的使用過程，以下為模板

配置：

1、Demo.Repository（1）NuGet包：①EntityFramework②Z.EntityFramework.Extensions③Z.Expressions.Eval④Z.EntityFramework.Plus.EF6注：②③為④的依賴項，先安裝②③再安裝④

2、Demo.Service（1）NuGet包：①Autofac②Autofac.Mvc5（2）引用：Demo.Repository

3、Demo.Mvc（1）NuGet包：①EntityFramework②Autofac③Autofac.Mvc5（2）引用：Demo.Repository、Demo.Service

數據庫映射

在Demo.Repository添加數據庫映射后，將Demo.Repository下的App.Config中關于數據庫連接的相關配置復制粘貼于Demo.Mvc下的Web.config中

AutofacConfig.cs

public static class AutofacConfig?? ?{?? ??? ?private static IContainer _container;?? ??? ?public static void InitAutofac()?? ??? ?{?? ??? ??? ?var builder = new ContainerBuilder();?? ??? ??? ?//注冊數據庫基礎操作和工作單元?? ??? ??? ?builder.RegisterGeneric(typeof(BaseDAL<>)).As(typeof(IBaseDAL<>)).PropertiesAutowired();?? ??? ??? ?builder.RegisterType(typeof(UnitWork)).As(typeof(IUnitWork)).PropertiesAutowired();?? ??? ??? ?//注冊service層?? ??? ??? ?builder.RegisterAssemblyTypes(Assembly.GetExecutingAssembly()).PropertiesAutowired();?? ??? ??? ?// 注冊controller，使用屬性注入?? ??? ??? ?builder.RegisterControllers(Assembly.GetCallingAssembly()).PropertiesAutowired();?? ??? ??? ?注冊所有的ApiControllers?? ??? ??? ?//builder.RegisterApiControllers(Assembly.GetCallingAssembly()).PropertiesAutowired();?? ??? ??? ?builder.RegisterModelBinders(Assembly.GetCallingAssembly());?? ??? ??? ?builder.RegisterModelBinderProvider();?? ??? ??? ?// OPTIONAL: Register web abstractions like HttpContextBase.?? ??? ??? ?//builder.RegisterModule<AutofacWebTypesModule>();?? ??? ??? ?// OPTIONAL: Enable property injection in view pages.?? ??? ??? ?builder.RegisterSource(new ViewRegistrationSource());?? ??? ??? ?// 注冊所有的Attribute?? ??? ??? ?builder.RegisterFilterProvider();?? ??? ??? ?// Set the dependency resolver to be Autofac.?? ??? ??? ?_container = builder.Build();?? ??? ??? ?//Set the MVC DependencyResolver?? ??? ??? ?DependencyResolver.SetResolver(new AutofacDependencyResolver(_container));?? ??? ??? ?//Set the WebApi DependencyResolver?? ??? ??? ?//GlobalConfiguration.Configuration.DependencyResolver = new AutofacWebApiDependencyResolver((IContainer)_container);?? ??? ?}?? ?}

BaseService.cs

public class BaseService<T> where T : class?? ?{?? ??? ?public IBaseDAL<T> BaseDAL { get; set; }?? ??? ?public IUnitWork UnitWork { get; set; }?? ?}

實現類

public class HandleService:BaseService<sy_sql>

BaseDal.where(...)

}

控制器調用

public HandleService HandleService{ get; set; }
