org.hibernate.exception.ConstraintViolationException：保存高級OneToMany替換項時無法執行JDBC批更新

Question

我正在做一個OneToMany關系，但是org.hibernate.exception.ConstraintViolationException：無法執行JDBC批處理更新錯誤發生。

堆棧跟蹤：

Hibernate: insert into DonorRecord (address, age, cnic, confirmPasswod, contactNumber, email, firstName, homeNumber, lastName, password, userName) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)
Hibernate: select nextval ('hibernate_sequence')
Hibernate: insert into BloodDonorClass (bloodType, donor_id, price, bloodId) values (?, ?, ?, ?)

我認為您的查詢存在主鍵沖突約束。 或者您有違反的外鍵約束。 嘗試檢查查詢的插入數據，請參見以下代碼塊：

    DonorRecord donor = new DonorRecord();
    BloodDonorClass blood = new BloodDonorClass();
    blood = (BloodDonorClass)bloodDonor.getBlood();
    donor = (DonorRecord)bloodDonor.getDonor();
    blood.setDonor(donor);
    HashSet<BloodDonorClass> bloods = new HashSet<BloodDonorClass>();
    bloods.add(blood);
    donor.setBlood(bloods);
