Question

So, i used Mark Seemann’s example to do dependency injection with Windsor in MVC 4 RC Web Api, but i get an exception saying that it can’t resolve the dependencies to my ApiController

public class StatisticsController : ApiController
{
    private readonly ILogger _logger;
    private readonly IClickMessageProducer _producer;

    public StatisticsController(ILogger logger, 
        IClickMessageProducer clickMsgProducer)
    {
        _logger = logger;
        _producer = clickMsgProducer;
    }

    public string Get(string msg, string con) {...}
}

My Global.asax looks like this:

protected void Application_Start()
    {
        // different configs removed for brevity

        BootstrapContainer();
    }

    private static IWindsorContainer _container;

    private static void BootstrapContainer()
    {
        _container = new WindsorContainer()
            .Install(FromAssembly.This(), new ProducerInstaller())
            .Install(FromAssembly.This(), new WebWindsorInstaller());

        GlobalConfiguration.Configuration.Services.Replace(
            typeof(IHttpControllerActivator),
            new WindsorHttpControllerActivator(_container));
    }

The Installers gives Windsor the references needed to IClickMessageProducer. I have it working with IController in a genuine MVC 4 project so i’m confident that part is working.

To specify, this is the error message i get, when trying to access a method in StatisticsController with a GET call to the API:

<Error>
<Message>An error has occurred.</Message>
<ExceptionMessage>
    Can't create component 'APIMVC.Controllers.StatisticsController'
    as it has dependencies to be satisfied. 
    'APIMVC.Controllers.StatisticsController' is waiting for the following 
    dependencies: - Service 'Castle.Core.Logging.ILogger' which was not registered.
</ExceptionMessage>
<ExceptionType>Castle.MicroKernel.Handlers.HandlerException</ExceptionType>
<StackTrace>...</StackTrace>
</Error>

The call being something like this:
“http://localhost:60000/api/statistics?msg=apitest&con=apimvc”

If anyone has a working example or just a comment to the problem about my Windsor implementation i’ll be happy to see it.

Answer 1

_container = new WindsorContainer().Install(FromAssembly.This(), new ProducerInstaller()).Install(FromAssembly.This(), new WebWindsorInstaller());

this was the part at fault. As you can see I call Install(FromAssembly.This()) twice witch caused the LoggerInstaller to try to add a LoggingFacilitytwice causing an error.

The new implementation would look like this:
_container = new WindsorContainer().Install(FromAssembly.This(), new ProducerInstaller(), new WebWindsorInstaller());
