Global文件

public class MvcApplication : System.Web.HttpApplication
    {
        private static IContainer Container { get; set; }
        protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            BundleConfig.RegisterBundles(BundleTable.Bundles);

            var builder = new ContainerBuilder();
            //根据名称约定（服务层的接口和实现均以Contract结尾），实现服务接口和服务实现的依赖
            builder.RegisterAssemblyTypes(Assembly.Load("BLOG.IBLL"), Assembly.Load("BLOG.BLL")).Where(t => t.Name.EndsWith("Contract")).AsImplementedInterfaces().PropertiesAutowired().InstancePerDependency();
            // 根据名称约定（数据访问层的接口和实现均以Repository结尾），实现数据访问接口和数据访问实现的依赖
            builder.RegisterAssemblyTypes(Assembly.Load("BLOG.IDAL"), Assembly.Load("BLOG.DAL")).Where(t => t.Name.EndsWith("Repository")).AsImplementedInterfaces().PropertiesAutowired().InstancePerDependency();
            builder.RegisterControllers(Assembly.GetExecutingAssembly()).PropertiesAutowired();
            Container = builder.Build();
            DependencyResolver.SetResolver(new AutofacDependencyResolver(Container));
        }
    }

 

控制器

public class DefaultController : Controller
    {
        //属性自动注入
        public IProvinceContract ProvinceContract { get; set; }
        // GET: Default
        public ActionResult Index()
        {
            return View();
        }
        public ActionResult GetProvinceList()
        {
            var list = ProvinceContract.GetList(p => p.Id > 0);
            return Json(list);
        }
    }

PropertiesAutowired 属性注入

IBLL

public interface IProvinceContract
    {
        /// <summary>
        /// 获取列表
        /// </summary>
        /// <param name="where"></param>
        /// <returns></returns>
        IQueryable<Province> GetList(Expression<Func<Province, bool>> where);
    }

BLL

 public class ProvinceContrator: IProvinceContract
    {
        //属性自动注入
        public IProvinceRepository ProvinceRepository { get; set; }
        public IQueryable<Province> GetList(Expression<Func<Province, bool>> where)
        {
            return ProvinceRepository.GetList(where);
        }
    }
