MVC4 controllerfactory based on Unity IOC framework

First, the untiy framework is introduced. Can be installed directly in the NuGet Package Manager.

New unitycontrollerfactory for inheriting defaultcontrollerfactory:

Override virtual method GetControllerInstance.

    Public classUnitycontrollerfactory:defaultcontrollerfactory { PublicIunitycontainer UnityContainer {Get;Private Set; }  Publicunitycontrollerfactory (Iunitycontainer unitycontainer) { This. UnityContainer =UnityContainer; }        protected OverrideIController getcontrollerinstance (RequestContext requestcontext, Type controllertype) {if(NULL==Controllertype) {                return NULL; }            return(IController) This.        Unitycontainer.resolve (Controllertype); }    }

Then the unity is activated in Global.asax:

protected voidApplication_Start () {arearegistration.registerallareas ();            Webapiconfig.register (globalconfiguration.configuration);            Filterconfig.registerglobalfilters (globalfilters.filters);            Routeconfig.registerroutes (routetable.routes); //as followsUnityContainer UnityContainer =NewUnityContainer (); //Iemployeerepository is the storage layer that needs to be relied uponUnitycontainer.registertype<iemployeerepository, employeerepository>(); Unitycontrollerfactory controllerfactory=Newunitycontrollerfactory (UnityContainer);        ControllerBuilder.Current.SetControllerFactory (controllerfactory); }

Next we need to develop a dependency property injection method in the controller.

The dependency feature is to tell us this dependency property

[Dependency]  Public Get set; }

There is also an activation method based on the Ninject IOC framework through Icontrolleractivator or Idependencyresolver.
