autofac

            var builder = new ContainerBuilder();

            builder.RegisterModule<AttributedMetadataModule>();



            builder.RegisterModule(new ConfigurationSettingsReader());  

  

            //如果是多个dll含有，要调用多次

            builder.RegisterControllers(typeof(MvcApplication).Assembly)

                    .PropertiesAutowired()  //注入到属性

                    .InstancePerHttpRequest();

            

            builder.RegisterSource(new ViewRegistrationSource());



           

            var container = builder.Build();



            DependencyResolver.SetResolver(new AutofacDependencyResolver(container));

          

在Global.asax.cs的Application_Start加入这段，我是习惯单独一个类里的一个方法做这个，然后被Application_Start调用

 

    public class LeaveController : Controller

    {

        private readonly IComponentContext _icoContext;

        private Lazy<ITest> Test

        {

            get;

            set;

        }



        public LeaveController(Lazy<ITest> test,IComponentContext icoContext)

        {

            _icoContext = icoContext;

            this.Test = test;

        }

        /// <summary>

        /// 用IComponentContext 来获得，显式调用Resolve

        /// </summary>

        /// <returns></returns>

        public ActionResult ContextIndex()

        {

            

            var test2 = _icoContext.Resolve<ITest>();



            return View("Index", "", test2.Test());

        }



        /// <summary>

        /// 用ApplicationContainer 来获得，显式调用Resolve

        /// </summary>

        /// <returns></returns>

        public ActionResult ApplicationIndex()

        {

            var test3 = AutofacDependencyResolver.Current.ApplicationContainer.Resolve<ITest>();



            return View("Index", "", test3.Test());

        }

        /// <summary>

        /// 用构造函数的Lazy加载

        /// </summary>

        /// <returns></returns>

        public ActionResult Index()

        {

            return View("Index", "", this.Test.Value.Test());

        }



    }

 

用构造函数注入的比较常见,IComponentContext和

 AutofacDependencyResolver.Current.ApplicationContainer另外做法
