How to wire up a controller's dependancy
So I went through the asp.net mvc tutorial for castle windsor, and my registrations look like:
private static IWindsorContainer _container = new WindsorContainer();
private static void BootstrapContainer()
{
_container = new WindsorContainer()
.Install(FromAssembly.This());
var controllerFactory = new WindsorControllerFactory(_container.Kernel);
开发者_Python百科 ControllerBuilder.Current.SetControllerFactory(controllerFactory);
}
protected void Application_End()
{
_container.Dispose();
}
So in my HomeController I have this:
public class HomeController : Controller
{
private IUserService _userService;
public HomeController(IUserService userService)
{
this._userService = userService;
}
}
How would I go about wiring this controller up to setup the IUserService?
Update In case in matters how I need to wire things up, my vs.net projects are:
web, interfaces, entities, data (nhibernate), services
The implementation of WindsorControllerFactory should look like this from the doco http://docs.castleproject.org/Windsor.Windsor-tutorial-part-two-plugging-Windsor-in.ashx?HL=ikernel.
public class WindsorControllerFactory : DefaultControllerFactory
{
private readonly IKernel kernel;
public WindsorControllerFactory(IKernel kernel)
{
this.kernel = kernel;
}
public override void ReleaseController(IController controller)
{
kernel.ReleaseComponent(controller);
}
protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType)
{
if (controllerType == null)
{
// Throw exception. Can't resolve null type.
}
return (IController)kernel.Resolve(controllerType);
}
}
UPDATED
Each interface that needs to be resolved by dependancy injection need to be registered.
This can be done by calling the .Register method on the container.
container.Register(Component.For<IUserService>().ImplementedBy<UserService>().LifeStyle.Transient);
