AutoMapper的安装和配置

public class AutoMapperConfigs:Profile
    {
        //通过构造函数把DTO映射到数据库实体,映射方向：左边映射到右边
        public AutoMapperConfigs()
        {
            //角色
            CreateMap<RoleAdd, Role>();
            CreateMap<RoleEdit, Role>();
            //用户
            CreateMap<UserAdd,Users>();
            CreateMap<UserEdit, Users>();
            //菜单
            CreateMap<MenuAdd, Menu>();
            CreateMap<MenuEdit, Menu>();
            
        }
    }

//AutoMapper映射
builder.Services.AddAutoMapper(typeof(AutoMapperConfigs));
