1.初始化
using System.Reflection; using System.Web; using System.Web.Mvc; using System.Configuration; using System; using System.IO; using Autofac; using Autofac.Core; using Autofac.Integration.Mvc; public static IContainer RegisterIOC() { ContainerBuilder builder = new ContainerBuilder(); //构造函数注入 builder.RegisterAssemblyTypes(Assembly.GetCallingAssembly()).AsImplementedInterfaces(); //注入控制器并实现属性注入 builder.RegisterControllers(Assembly.GetCallingAssembly()).PropertiesAutowired(); //支持过滤器的属性注入 builder.RegisterFilterProvider(); builder.RegisterType<AccountService>().As<IAccountService>(); var container = builder.Build(); DependencyResolver.SetResolver(new AutofacDependencyResolver(container)); return container; }
2.在global.asax.cs
protected void Application_Start() { AreaRegistration.RegisterAllAreas(); WebApiConfig.Register(GlobalConfiguration.Configuration); FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); RouteConfig.RegisterRoutes(RouteTable.Routes); BundleConfig.RegisterBundles(BundleTable.Bundles); Func<ILifetimeScope, ILifetimeScope> scopeProvider = (ILifetimeScope container) => { if (HttpContext.Current.Items[typeof(ILifetimeScope)] == null) { HttpContext.Current.Items[typeof(ILifetimeScope)] = container.BeginLifetimeScope("AutofacWebRequest"); } return (ILifetimeScope)HttpContext.Current.Items[typeof(ILifetimeScope)]; }; scopeProvider (RegisterIOC()) }
3.手工获取
public class BeanFactory { /// <summary> /// 获取Bean /// </summary> /// <typeparam name="T">获取的实例类型</typeparam> /// <returns>获取的实例</returns> public static T GetBean<T>() { try { if (System.Web.HttpContext.Current != null) { ILifetimeScope scope = System.Web.HttpContext.Current.Items[typeof(ILifetimeScope)] as ILifetimeScope; if (scope != null) { return scope.Resolve<T>(); } } } catch { } return ServiceLocator.Current.GetInstance<T>(); } /// <summary> /// 获取Bean /// </summary> /// <param name="type"></param> /// <returns></returns> public static object GetBean(System.Type type) { try { if (System.Web.HttpContext.Current != null) { ILifetimeScope scope = System.Web.HttpContext.Current.Items[typeof(ILifetimeScope)] as ILifetimeScope; if (scope != null) { return scope.Resolve(type); } } } catch { } return ServiceLocator.Current.GetInstance (type) ; } }
