Inject AutoMapper

I have been working on injecting AutoMapper into controllers. I like the implementation of Code Camp Server. It creates a wrapper around AutoMapper's IMappingEngine. The dependency injection is done using StructureMap. But I need to use Castle Windsor for my project. So, how do we implement the following dependency injection and set-up using Windsor? I am not looking for line-by-line equivalent implementation in Castle Windsor. If you want to do that, please feel free. Instead, what is Windsor equivalent of StructureMap's Registry and Profile? I need Profile to define CreateMap<> like the following.

Thanks.

Meeting controller:

public MeetingController(IMeetingMapper meetingMapper, ...)

Meeting Mapper:

public class MeetingMapper : IMeetingMapper
{

    private readonly IMappingEngine _mappingEngine;

    public MeetingMapper(IMappingEngine mappingEngine)
    {
      _mappingEngine = mappingEngine;
    }

    public MeetingInput Map(Meeting model)
    {
        return _mappingEngine.Map<Meeting, MeetingInput>(model);    
    }

    ......
}

Auto Mapper Registry:

public class AutoMapperReg开发者_如何学JAVAistry : Registry
{

    public AutoMapperRegistry()
    {
        ForRequestedType<IMappingEngine>().TheDefault.Is.ConstructedBy(() => Mapper.Engine);
    }
}

Meeting Mapper Profile:

public class MeetingMapperProfile : Profile
{

    public static Func<Type, object> CreateDependencyCallback = (type) => Activator.CreateInstance(type);

    public T CreateDependency<T>()
    {
        return (T)CreateDependencyCallback(typeof(T));
    }

    protected override void Configure()
    {
        Mapper.CreateMap<MeetingInput, Meeting>().ConstructUsing(
            input => CreateDependency<IMeetingRepository>().GetById(input.Id) ?? new Meeting())

       .ForMember(x => x.UserGroup, o => o.MapFrom(x => x.UserGroupId))
       .ForMember(x => x.Address, o => o.Ignore())
       .ForMember(x => x.City, o => o.Ignore())
       .ForMember(x => x.Region, o => o.Ignore())
       .ForMember(x => x.PostalCode, o => o.Ignore())
       .ForMember(x => x.ChangeAuditInfo, o => o.Ignore());
    }
}

you mean how do you register it in Windsor?

you may have to register FactorySupportFacility fist... I have no way of checking at this moment.

container.AddFacility<FactorySupportFacility>();

and then

container.Register(Component.For<IMappingEngine>().UsingFactoryMethod(()=>
            Mapper.Engine));

I'm not familiar with Castle Windsor but here is the StructureMap syntax. You would need to set up your registry a little different. Instead of setting the IMappingEngine to Mapper.Engine, you will have to do configure a few more interfaces. It's a little more work but this will allow you to set the profile as part of registration.

public AutoMapperRegistry()
{
    //type mapping
    For<ConfigurationStore>()
        .Singleton()
        .Use(ctx =>
        {
            ITypeMapFactory factory = ctx.GetInstance<ITypeMapFactory>();
            ConfigurationStore store 
                = new ConfigurationStore(factory, MapperRegistry.AllMappers());
            IConfiguration cfg = store;
            //Here's where you load your profile
            cfg.AddProfile<MeetingMapperProfile>();
            store.AssertConfigurationIsValid();
            return store;
        });
    For<IConfigurationProvider>().Use(ctx => ctx.GetInstance<ConfigurationStore>());
    For<IConfiguration>().Use(ctx => ctx.GetInstance<ConfigurationStore>());
    For<IMappingEngine>().Use<MappingEngine>();
    For<ITypeMapFactory>().Use<TypeMapFactory>();
}

I realize this is a bit old, but I use Castle Windsor, and it's been fairly easy to get AutoMapper profiles loaded using an installer:

using System.Linq;
using System.Reflection;

using AutoMapper;

using Castle.MicroKernel.Registration;
using Castle.MicroKernel.SubSystems.Configuration;
using Castle.Windsor;

namespace YourNamespace
{
    public class AutoMapperInstaller : IWindsorInstaller
    {
        public void Install(IWindsorContainer container, IConfigurationStore store)
        {
            Mapper.Initialize(m => m.ConstructServicesUsing(container.Resolve));

            container.Register(Types.FromAssembly(Assembly.GetExecutingAssembly()).BasedOn<IValueResolver>());
            container.Register(Types.FromThisAssembly().BasedOn<Profile>().WithServiceBase());
            var profiles = container.ResolveAll<Profile>();
            profiles.ToList().ForEach(p => Mapper.AddProfile(p));

            container.Register(Component.For<IMappingEngine>().Instance(Mapper.Engine));
        }
    }
}

This installer would pick up the MeetingMapperProfile shown in the question, or any other class based on AutoMapper's Profile.
