我正在執行OneToMany關係，但發生org.hibernate.exception.ConstraintViolationException：無法執行JDBC批處理更新錯誤。org.hibernate.exception.ConstraintViolationException：無法在保存hibrnate OneToMany關聯時執行JDBC批處理更新
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 (?, ?, ?, ?)
