数据库绑定问题--abp框架自动迁移多出列的解决办法

定义实体，例如，

using CustomerManagement.Tracking.Exceptions;
using System;
using System.Diagnostics.Contracts;
using System.Numerics;
using Volo.Abp.Domain.Entities.Auditing;

namespace CustomerManagement.Tracking.CustomerArchives
{
    public class PlanPrice : CreationAuditedEntity
    {
        protected PlanPrice()
        {
}
        /// <summary>
        ///   方案Id
        /// </summary>
        public Guid PlanId { get; private set; }
        public Guid CustomerId { get; private set; }
        public Customer Customer { get; private set; } = null!;
        /// <summary>
        ///   方案
        /// </summary>
        public CustomerPlan Plan { get; private set; } = null!;
/// <summary>
        /// 合同签订时间
        /// </summary>
        public DateTime? ContractTime { get; private set; }

        public PlanPriceStatus Status { get; set; } = PlanPriceStatus.报价中;public override object[] GetKeys()
        {
            return new object[] { PlanId };
        }
    }
}

 \src\CustomerManagement.Tracking.EntityFrameworkCore\EntityFrameworkCore

        builder.Entity<CustomerPlan>(typeBuilder =>
        {
            typeBuilder.ConfigureByConvention(); // 只调用这个
        });
        builder.Entity<PlanPrice>(b =>
        {
            b.ToTable("PlanPrice");
            b.ConfigureByConvention();

            // 1. 设置主键（既然你想主外键合一）
            b.HasKey(x => x.PlanId);

            // 2. 配置与 Customer 的关系---写明显示调用，拒绝喂饭
            b.HasOne(x => x.Customer)
             .WithMany() // <--- 关键：不要在括号里写 x => x.PlanPrices
             .HasForeignKey(x => x.CustomerId)
             .OnDelete(DeleteBehavior.NoAction);

            // 3. 配置与 Plan 的关系
            b.HasOne(x => x.Plan)
             .WithOne() // 1:1 关系
             .HasForeignKey<PlanPrice>(x => x.PlanId)
             .IsRequired();
        });
    }

如果还是数据库迁移出现多余的列，搜索删除迁移文件的多余的列以及design.cs文件删除有关多余的列即可
