我想注入配置对象到Mapster.下面是代码.

public class DownloadLinkMappingConfig : IRegister
    {
        private readonly IConfiguration Configuration;

        public DownloadLinkMappingConfig(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public void Register(TypeAdapterConfig config)
        {
            config.NewConfig<DownloadLink, DownloadLinkImage>()
                .Map(d => d.Id, s => s.Id)
                .Map(x => x.CompanyId, y => y.CompanyId)
                .Map(x => x.Name, y => y.Name)
                .Map(x => x.Url, y => y.Url)
                .Map(target => target.Image, source => Configuration.GetValue<string>($"DownloadLinkImages:{source.Name}"));
        }
    }

DI部分：

var typeAdapterConfig = TypeAdapterConfig.GlobalSettings;
typeAdapterConfig.Scan(Assembly.GetExecutingAssembly());
services.AddSingleton<IMapper>(new Mapper(typeAdapterConfig));

依赖注入仅适用于不注入配置对象的Map器配置。
