            //DependencyResolver.SetResolver(new AutofacDependencyResolver(container));

           var builder = new ContainerBuilder();

            // 家在所有程序集
            builder.RegisterApiControllers(Assembly.GetExecutingAssembly());    // IHttpController in current assembly
            //builder.RegisterModule<ApiControllerModule>();                      // IHttpController in separate assemblies
            builder.RegisterModule(new ConfigurationSettingsReader());
    
            builder.RegisterWebApiFilterProvider(config);
    
            // Set the dependency resolver to be Autofac
            var container = builder.Build();
            config.DependencyResolver = new AutofacWebApiDependencyResolver(container);
    
    }
