Idea from this post.
By default, MVC2 can’t handle ctor injection.
[HandleError]
public class HomeController : Controller
{
private readonly IGreatingService _greatingService;
public HomeController(IGreatingService greatingService)
{
_greatingService = greatingService;
}
public ActionResult Index()
{
ViewData["Message"] = "Welcome to ASP.NET MVC!" + _greatingService.SayHello();
return View();
}
}
Solution: A custom ControllerFactroy can be set in App_start.
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RegisterRoutes(RouteTable.Routes);
ControllerBuilder.Current.SetControllerFactory(IoC.GetControllerFactory());
}
public static class IoC
{
public static IKernel Kernel;
static IoC()
{
// ObjectFactory.Initialize(x => x.AddRegistry(new ControllerDependencyRegistry()));
Kernel = new StandardKernel(new ControllerModule());
}
public static IControllerFactory GetControllerFactory()
{
return new ControllerFactory();
}
public static object Get(Type type)
{
// return ObjectFactory.GetInstance(type);
return Kernel.Get(type);
}
}
public class ControllerFactory : DefaultControllerFactory
{
protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType)
{
if (controllerType == null)
{
return base.GetControllerInstance(requestContext, controllerType);
}
return IoC.Get(controllerType) as Controller;
}
}
// Ninject implementation
public class ControllerModule : NinjectModule
{
public override void Load()
{
Bind<IGreatingService>().To<GreatingService>();
}
}
// StructureMap implementation
public class ControllerDependencyRegistry : Registry
{
public ControllerDependencyRegistry()
{
For<IGreatingService>().Use<GreatingService>();
}
}
