我一直致力于将 AutoMapper 注入控制器。我喜欢 Code Camp Server 的实现。它围绕 AutoMapper 的 IMappingEngine 创建一个包装器。依赖注入是使用 StructureMap 完成的。但我的项目需要使用 Castle Windsor。那么，我们如何使用 Windsor 实现以下依赖注入和设置呢？我不是在 Castle Windsor 中寻找逐行等效实现。如果您想这样做，请随意。相反，什么是 Windsor 等效于 StructureMap 的注册表和配置文件？我需要 Profile 来定义 CreateMap<>，如下所示。

谢谢。

public MeetingController(IMeetingMapper meetingMapper, ...)

会议映射器：

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);    
    }

    ......
}

自动映射器注册表：

public class AutoMapperRegistry : Registry
{

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

会议映射器简介：

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());
    }
}

你的意思是你如何在温莎注册它？

您可能必须注册 FactorySupportFacility 拳头...我目前无法检查。

container.AddFacility<FactorySupportFacility>();

接着

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

我对 Castle Windsor 不熟悉，但这里是 StructureMap 语法。您需要对注册表进行一些不同的设置。无需将 IMappingEngine 设置为 Mapper.Engine，您将不得不配置更多接口。这需要做更多的工作，但这将允许您将配置文件设置为注册的一部分。

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>();
}

我意识到这有点老了，但我使用 Castle Windsor，并且使用安装程序加载 AutoMapper 配置文件相当容易：

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));
        }
    }
}

此安装程序将选择MeetingMapperProfile问题中显示的内容，或基于 AutoMapper 的任何其他类Profile。
