問題描述

長話短說：

這是優惠券系統。 實體是公司，客戶，優惠券。 公司生成優惠券。 每個公司在MANY（coupon）_To_ONE（company）關系中都有自己的優惠券集合。 任何客戶都可以購買任何優惠券。 這反映了MANY（客戶）_To_MANY（優惠券）關系。

任何優惠券都可以刪除。 創建它的公司決定刪除它，或者EndDate被傳遞並由每日線程自動刪除。 將會發生什么：一旦刪除-創建它的公司-不再擁有它，購買它的任何客戶-不再擁有它，並且它的記錄應該完全消失。

實踐中：我可以手動刪除優惠券，如果沒有客戶持有，則可以自動刪除。 但是，如果客戶持有優惠券，而我嘗試刪除此優惠券，則會收到錯誤消息： 

org.apache.derby.client.am.SqlException: DELETE on table 'COUPON' caused a violation of foreign key constraint 'FKPPNDQDPYDMSUMC9YQSLM5HSS4' for key (21).  The statement has been rolled back.

CompanyFacade （保存公司的所有業務邏輯，驗證信息並調用JpaRepository方法）removeCoupon（）： 

public void removeCoupon(Coupon coupon) throws ConnectionPoolException, DAOException, CouponDontExistException {
    if (couponDao.getOne(coupon.getId()) != null) {
        couponDao.delete(coupon);
    } else {
        throw new CouponDontExistException(
                "Failed to remove Coupon. coupon with id " + coupon.getId() + " cannot be found;");
    }
}

優惠券 （定義與COMPANY的關系） 

@Entity
public class Coupon {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private long id;
    private String title;
    @Column(name = "startDate")
    private Date startDate;
    @Column(name = "endDate")
    private Date endDate;
    private int amount;
    private CouponType type;
    private String message;
    private double price;
    private String image;
    @ManyToOne(fetch = FetchType.LAZY, optional = false)
    @JoinColumn(name = "company_id", nullable = false)
    @OnDelete(action = OnDeleteAction.CASCADE)
    @JsonIgnore
    private Company company;

公司 

@Entity
public class Company {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private long id;
    @Column(unique = true)
    private String compName;
    private String password;
    private String email;

客戶 （定義與COUPON的關系） 

@Entity
public class Customer {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private long id;
    @Column(unique = true)
    private String custName;
    private String password;
    @ManyToMany(fetch = FetchType.LAZY)
    @JoinTable(name = "CUSTOMER_COUPON", joinColumns = @JoinColumn(name = "customerId"), inverseJoinColumns = @JoinColumn(name = "couponId"))
    private Set<Coupon> coupons;

我想念什么？ 其他一切工作都很好。 您的建議將不勝感激。

2 個解決方案

解決方案1
 0  2018-08-31 12:25:02

從我的角度來看，你有一個

@OnDelete（操作= OnDeleteAction.CASCADE）

在您的優惠券定義中，此處不需要。 但這在“客戶與多對多”關系中是必需的。 那是因為當您刪除優惠券時，關系將轉到公司，因此這里不需要刪除級聯。

當客戶持有優惠券的多對多引用時，您需要級聯刪除，或者必須先刪除m-2-m關系，然后才能刪除優惠券。

解決方案2

已解決：我認為由於在客戶實體上定義了ManyToMany認證，並且現成的休眠JPA接口在這里將無用，所以我必須編寫自己的自定義查詢： 

String query = "DELETE FROM customer_coupon WHERE coupon_id = ";
query += coupon.getId();

事實證明這很困難，因為JPArepository將不接受這種本機SQL，而我無法弄清它的JPQL語法，或者它是完全不可能的：不斷出現一個未映射customer_coupon表的異常（盡管它確實存在）。

由於這個原因，我必須找到一種使用spring的EntityManager並直接在DB上執行自定義查詢的方法，以及可能需要它們的每個JPA操作。 為此，我編寫了一個帶有顯式方法的實用程序存儲庫類。 這成功了： 

@Service
public class UtilRespository {

    @PersistenceContext
    private EntityManager em;

    @Transactional
    public int removeCouponOwnership(Coupon coupon) {
        String query = "DELETE FROM customer_coupon WHERE coupon_id = ";
        query += coupon.getId();

        Query q = em.createNativeQuery(query);
        int removed = q.executeUpdate();
        em.close();
        System.out.println("Successfully removed Coupon " + coupon.getId() + " from " + removed + " customers;");
        return removed;
    }
}
