子行を追加または更新できません：Hibernateで外部キー制約が失敗します

ちょっとデータをデータベースに挿入しようとしていますが、エラーが発生しました。子行を追加または更新できません：Hibernateで外部キー制約が失敗します

は、子行を追加または更新できません：外部キー制約が失敗した（。posをexchange_order_detail、CONSTRAINT FK_5ed8cb725cbc40e2be44a4ab3d9 FOREIGN KEY（GOODS_DETAIL_ID2）がgoods_detail（ID）を参照）

ここに私のコードは

別ですJavaクラス

package com.istana.pos.db.domain; 

import javax.persistence.Column; 
import javax.persistence.Entity; 
import javax.persistence.FetchType; 
import javax.persistence.GeneratedValue; 
import javax.persistence.GenerationType; 
import javax.persistence.Id; 
import javax.persistence.JoinColumn; 
import javax.persistence.ManyToOne; 
import javax.persistence.Table; 

@SuppressWarnings("serial") 
@Entity 
@Table(name = "EXCHANGE_ORDER_DETAIL", schema = "pos") 
public class ExchangeOrderDetail implements java.io.Serializable { 

    private int id; 
    private String exchangeNumber; 
    private Integer goodsDetailId1; 
    private Integer goodsDetailId2; 
    private double price1; 
    private double price2; 
    private double discount1; 
    private double discount2; 

    private ExchangeOrder exchangeOrder; 
    private GoodsDetail goodsDetail1; 
    private GoodsDetail goodsDetail2; 

    @Id 
    @Column(name = "ID", unique = true, nullable = false) 
    @GeneratedValue(strategy = GenerationType.AUTO) 
    public int getId() { 
     return this.id; 
    } 

    public void setId(int id) { 
     this.id = id; 
    } 

    @Column(name = "EXCHANGE_NUMBER", nullable = false) 
    public String getExchangeNumber() { 
     return exchangeNumber; 
    } 

    public void setExchangeNumber(String exchangeNumber) { 
     this.exchangeNumber = exchangeNumber; 
    } 

    @Column(name = "GOODS_DETAIL_ID1", nullable = false) 
    public Integer getGoodsDetailId1() { 
     return goodsDetailId1; 
    } 

    public void setGoodsDetailId1(int goodsDetailId1) { 
     this.goodsDetailId1 = goodsDetailId1; 
    } 

    @Column(name = "GOODS_DETAIL_ID2", nullable = false) 
    public Integer getGoodsDetailId2() { 
     return goodsDetailId2; 
    } 

    public void setGoodsDetailId2(int goodsDetailId2) { 
     this.goodsDetailId2 = goodsDetailId2; 
    } 

    @Column(name = "PRICE1") 
    public double getPrice1() { 
     return price1; 
    } 

    public void setPrice1(double price1) { 
     this.price1 = price1; 
    } 

    @Column(name = "PRICE2") 
    public double getPrice2() { 
     return price2; 
    } 

    public void setPrice2(double price2) { 
     this.price2 = price2; 
    } 

    @Column(name = "DISCOUNT1") 
    public double getDiscount1() { 
     return discount1; 
    } 

    public void setDiscount1(double discount1) { 
     this.discount1 = discount1; 
    } 

    @Column(name = "DISCOUNT2") 
    public double getDiscount2() { 
     return discount2; 
    } 

    public void setDiscount2(double discount2) { 
     this.discount2 = discount2; 
    } 

    @ManyToOne(fetch = FetchType.EAGER) 
    @JoinColumn(name = "EXCHANGE_NUMBER", nullable = true, insertable = false, updatable = false, referencedColumnName = "EXCHANGE_NUMBER") 
    public ExchangeOrder getExchangeOrder() { 
     return exchangeOrder; 
    } 

    public void setExchangeOrder(ExchangeOrder exchangeOrder) { 
     this.exchangeOrder = exchangeOrder; 
    } 

    @ManyToOne(fetch = FetchType.LAZY) 
    @JoinColumn(name = "GOODS_DETAIL_ID1", nullable = false, insertable = false, updatable = false, referencedColumnName = "ID") 
    public GoodsDetail getGoodsDetail1() { 
     return goodsDetail1; 
    } 

    public void setGoodsDetail1(GoodsDetail goodsDetail1) { 
     this.goodsDetail1 = goodsDetail1; 
    } 

    @ManyToOne(fetch = FetchType.LAZY) 
    @JoinColumn(name = "GOODS_DETAIL_ID2", nullable = false, insertable = false, updatable = false, referencedColumnName = "ID") 
    public GoodsDetail getGoodsDetail2() { 
     return goodsDetail2; 
    } 

    public void setGoodsDetail2(GoodsDetail goodsDetail2) { 
     this.goodsDetail2 = goodsDetail2; 
    } 

}

そしてここにデータを作成するサービスがあります

public ExchangeOrder createExchangeOrder(ExchangeOrder domain, List<ExchangeOrderDetail> details, List<BankPayment> bankPayments) { 
     ExchangeOrder newDomain = exchangeOrderDao.saveNew(domain); 
     if (domain != null) { 
      for (ExchangeOrderDetail detail : details) { 
       System.out.println("saving exchange order 2"); 
       if (d.getGoodsDetail2() != null) { 
        detail.setExchangeNumber(newDomain.getExchangeNumber()); 
        detail.setExchangeOrder(newDomain); 
        exchangeOrderDetailDao.saveNew(detail); 
       } 
      } 
      for (BankPayment bp : bankPayments) { 
       bp.setTransactionNumber(domain.getExchangeNumber()); 
       bankPaymentDao.saveNew(bp); 
      } 
     } 
     return newDomain; 
    }

ありがとうございます。

私はこれを引き起こす可能性のあるいくつかの可能性の問題を参照してください。あなたが同じクラスのGOODS_DETAIL_ID1ため@ColumnともGOODS_DETAIL_ID1列の@ManyToOneで注釈を付けIntegerの両方を使用している理由は、何らかの理由

を？
goodsDetail1とgoodsDetail2の値はヌルである必要がありますが、提供したコードにこれらの値を設定することは表示されません。
GoodsDetailエンティティが設定されている場合は、明示的なカスケード保存が行われていないため、ExchangeOrderDetailを保存する前に保存してください。
