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
