注入AutoMapper

问题描述

我一直在努力将AutoMapper注入控制器.我喜欢Code Camp服务器的实现.它围绕AutoMapper的IMappingEngine创建包装器.依赖项注入是使用StructureMap完成的.但是我需要在项目中使用温莎城堡.那么，我们如何使用Windsor实施以下依赖项注入和设置?我不是在温莎城堡中寻找逐行等效的实现.如果您想这样做，请放心.相反，温莎相当于StructureMap的注册表和配置文件的内容是什么?我需要Profile来定义CreateMap<>，如下所示.

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.

谢谢.

会议控制器:

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);
    }
}

会议映射器配置文件:

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());
    }
}

推荐答案

您的意思是如何在Windsor中注册它?

you mean how do you register it in Windsor?

您可能必须注册FactorySupportFacility拳头...目前我无法检查.

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

container.AddFacility<FactorySupportFacility>();

然后

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