public class Trainer{
@OneToMany(cascade={CascadeType.ALL}, mappedBy="trainer")
private List<Crew> crew;
}
public class Crew {
@ManyToOne
@JoinColumn(name = "trainer_id")
private Trainer trainer;
}
以上是我的实体，我正在使用spring数据jpa存储库。除了培训师API，我还实现了回滚交易。
@Transactional(rollbackFor= {IOException.class,InterruptedException.class})
public add() {
trainer = trainerRepository.save(trainer);
}
因此每次在保存中都会从事务类 org.springframework.transaction.interceptor.TransactionAspectSupport 中获取异常，但将其更改为 CascadteType.Merge 的工作完美无缺使用 CascadeType.ALL

以下是供参考的代码。
Trainer trainer = new Trainer();
Crew crew = new Crew();
crew.setTrainer(trainer);
crew.setCt(createdTime);
crew.setCreatedBy(createdBy);
List<Crew> crews = new ArrayList<Crew>();
crews.add(crewMember);
