Autofac依赖注入框架

最近使用Autofac框架做项目的依赖注入，感觉挺好用的。

没有深入研究，只是拿来用用，具体可以去官网看看：https://autofac.org/。

这里只是贴一下最近项目的配置：

public partial class Startup

    {

        public void ConfigureContainer(IAppBuilder app)

        {

            var builder = new ContainerBuilder();

            // You can register controllers all at once using assembly scanning...

            builder.RegisterControllers(typeof(MvcApplication).Assembly);

            // Get your HttpConfiguration.

            var config = GlobalConfiguration.Configuration;

            // Register your Web API controllers.

            builder.RegisterApiControllers(Assembly.GetExecutingAssembly());

            // OPTIONAL: Register the Autofac filter provider.

            builder.RegisterWebApiFilterProvider(config);

            // OPTIONAL: Register the Autofac model binder provider.

            builder.RegisterWebApiModelBinderProvider();

            // ...or you can register individual controlllers manually.

            //builder.RegisterType<HomeController>().InstancePerRequest();

            builder.RegisterModule<AutofacWebTypesModule>();//Register Web Abstractions

            builder.RegisterSource(new ViewRegistrationSource());//Enable Property Injection for View Pages

            builder.RegisterFilterProvider();//Enable Property Injection for Action Filters

            builder.RegisterType<EFDbContext>().As<IDbContext>().InstancePerRequest();

            builder.RegisterGeneric(typeof(Repository<>)).As(typeof(IRepository<>)).InstancePerLifetimeScope();

            builder.RegisterType<MemoryCacheManager>().As<ICacheManager>().InstancePerRequest();

            #region  Service

            builder.RegisterType<SysUserService>().As<ISysUserService>().InstancePerLifetimeScope();

            //注册各种服务

            #endregion

            var container = builder.Build();

            DependencyResolver.SetResolver(new AutofacDependencyResolver(container));

            config.DependencyResolver = new AutofacWebApiDependencyResolver(container);

            RuntimeContext.Instance.ContainerManager = new ContainerManager(container);//存储到全局实例中

            // OWIN MVC SETUP:

            // Register the Autofac middleware FIRST, then the Autofac MVC middleware.

            app.UseAutofacMiddleware(container);

            app.UseAutofacMvc();

        }

    }

项目是基于MVC的，利用Startup的partialt特性，加了上面依赖注入配置方法ConfigureContainer，然后可以在MVC的Startup类的Configuration方法中调用该方法，如下：

 public void Configuration(IAppBuilder app)

 {

   ConfigureContainer(app);

 }

OK,依赖注入搞定了.
