在你的OnModelCreating中的上下文类：

In your Context class in OnModelCreating:

modelBuilder.Entity<GiftCouponPayment>()
                .Map(m =>
                {
                    m.MapInheritedProperties();
                    m.ToTable("GiftCouponPayment");
                });

modelBuilder.Entity<ClubCardPayment>()
                .Map(m =>
                {
                    m.MapInheritedProperties();
                    m.ToTable("ClubCardPayment");
                });
