automapper 10 +autofac+asp.net web api

automapper 不必多说 https://automapper.org

autofac 这里也不多说 https://autofac.org

这里主要 说 automapper 10.0 版本+autofac 在asp.net web api 的简单使用，因为automapper 更新很快每个版本的差别很大 ，网上查找的资料也比较杂而乱,找了好半天也找不出个好的

也没写过啥博文直接上干货

1.vs nuget 中搜索 automapper 安装

2.在项目中添加 此类 记得集成  Profile

public class MappingProfile : Profile
    {
        public MappingProfile()
        {//此处是类与类的映射.... 这里就简单的举例一个

            CreateMap<Core.Model.PO.admin, Models.Default.Admin>();

        }

    }

3.在autofac 中 注册  automapper

   public static void Register()
        {
            //得到你的HttpConfiguration.
            var configuration = GlobalConfiguration.Configuration;
            var builder = new ContainerBuilder();
            //注册所有api控制器  构造函数注入
            builder.RegisterApiControllers(Assembly.GetCallingAssembly());

            // 注册auto mapper
            var mapperConfiguration = new MapperConfiguration(cfg =>
            {
                cfg.AddProfile<MappingProfile>();//添加MappingProfile 实现映射的类
            });
            IMapper mapper = mapperConfiguration.CreateMapper();
            builder.RegisterInstance(mapper).As<IMapper>().SingleInstance();

...... 此处省去代码 100行
}

4.在控制器构造函数中 使用 IMapper

  public class DefaultController : ApiController
    {
         private readonly IMapper _mapper;
        private readonly IAdminService _adminService;
        public DefaultController(IMapper mapper, IAdminService adminService)
        {
            _mapper = mapper;
            _adminService = adminService;
        }

        [HttpGet,Filter.CustomActionFilter]
        public IHttpActionResult user()
        {
            List<Core.Model.PO.admin> list = _adminService.GetList();
            var customers = _mapper.Map<List<Admin>>(list);

            return Ok(new {code=0 ,data=customers });
        }
    }
