Automapper映射异常之注册

1.映射报错

原因：
需要在startup.cs中添加Automapper映射

点击查看代码

builder.Services.AddAutoMapper(typeof(AutoMapperConfigs));

AutoMapperConfigs类需要继承profile

点击查看代码

/// <summary>
    /// Dto的映射配置
    /// </summary>
    public class AutoMapperConfigs: Profile
    {
        public AutoMapperConfigs()
        {
            //用户
            CreateMap<User, UserRes>();
        }
    }
