1.AutoMapper的使用

1、引入Nuget包 AutoMapper、AutoMapper.Extensions.Microsoft.DependencyInjection
2、新建Config文件夹，以及AutoMapperConfigs文件，引用Profile
3、在构造函数中管理映射关系：CreateMap<Users, UserRes>();
4、在Program中注册
builder.Services.AddAutoMapper(typeof(AutoMapperConfigs));
5、使用
return _mapper.Map<UserRes>(user);

2 创建输入输出Dto

using System.Text;
using System.Threading.Tasks;

namespace WebModel.Dto.Menu
{
    public class MenuAdd
    {
        public string Name { get; set; }
        public string Index { get; set; }
        public string FilePath { get; set; }
        public long ParentId { get; set; }
        public int Order { get; set; }
        public bool IsEnable { get; set; }

        /// <summary>
        /// 描述
        /// </summary>
        public string Description { get; set; }
    }
}

在WebApi => Config => AutoMapperConfigs 配置关系映射

using AutoMapper;
using Model.Dto.Role;
using Model.Dto.User;
using WebModel.Dto.Menu;
using WebModel.Entitys;

namespace WebApi.Config
{
    /// <summary>
    /// Dto 映射配置
    /// </summary>
    public class AutoMapperConfigs:Profile
    {
        /// <summary>
        /// 映射配置
        /// </summary>
        public AutoMapperConfigs()
        {

            //角色
            CreateMap<Role, RoleRes>();
            CreateMap<RoleAdd, Role>();
            CreateMap<RoleEdit, Role>();
            // 用户
            CreateMap<Users, UserRes>();
            CreateMap<UserAdd, Users>();
            CreateMap<UserEdit, UserRes>();
            // 菜单
            CreateMap<Menu, MenuRes>();
            CreateMap<MenuAdd, Menu>();
            CreateMap<MenuEdit, Menu>();
        }
    }
}

最后在注入到配置文件中(HostBuilderExtend.cs)

using Autofac;
using Autofac.Extensions.DependencyInjection;
using SqlSugar;
using System.Runtime.CompilerServices;

namespace WebApi.Config
{
    /// <summary>
    /// 注册类-扩展
    /// </summary>
    public static class HostBuilderExtend
    {
        public static void Register(this WebApplicationBuilder app)
        {
            // 1. nuGet 安装 autofac
            app.Host.UseServiceProviderFactory(new AutofacServiceProviderFactory());
            app.Host.ConfigureContainer<ContainerBuilder>(builder =>
            {
                #region 注册 sqlsugar
                builder.Register<ISqlSugarClient>(context =>
                {
                    SqlSugarClient db = new SqlSugarClient(new ConnectionConfig()
                    {
                        //数据库配置地址
                        ConnectionString = "Server=;Database=zxAdminDb;Uid=sa;Pwd=root",
                        DbType = DbType.SqlServer,
                        IsAutoCloseConnection = true
                    });
                    //支持SQL 语句的输出，方便排查问题
                    db.Aop.OnLogExecuted = (sql, par) =>
                    {
                        Console.WriteLine("\r\n");
                        Console.WriteLine($"{DateTime.Now.ToString("yyyyMMdd HH:mm:ss")},Sql语句:{sql}");
                        Console.WriteLine("===================================================");
                    };
                    return db; 
                });
                #endregion

                // 注册接口和实现层
                builder.RegisterModule(new AutofacModuleRegister());
            });
            //Automapper映射
            app.Services.AddAutoMapper(typeof(AutoMapperConfigs));
        }

    }
}
