spring数据,hibernate,无法在请求的新事务中保存相关实体

Entity 与该实体的关系。

@Data
@Entity
@Table(name = "CHARGES")
public class Charge {

    @Id
    @Column(name = "GUID", nullable = false)
    private String guid;

    ...

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "ORIGIN_CHARGE_GUID")
    private Charge chargeOrigin;

    @Column(name = "IS_ACTIVE")
    private Boolean isActive;

IS_ACTIVE 有约束(只有一个 Charge 可以是 true )

我用方法节省的每一笔费用 @Transactional(propagation = Propagation.REQUIRES_NEW)

@Transactional
public void mainMethod { // Root transaction
      for (Charge charge: charges) {
        //try
        saveOneCharge(charges);
        //catch
    }
 }

@Transactional(propagation = Propagation.REQUIRES_NEW)//internal transaction
public Charge saveOneCharge(Charge charge) {
    return chargesRepository.saveAndFlush(charge);
}

但现在我需要改变 isActive

charge.seActive(True);
charge.getChargeOrigin().setActive(false);
chargeService.saveOneCharge(charge)

我得到了异常(约束异常)

charge.setIsActive(false);
charge.getChargeOrigin().setActive(false);
Charge deactivatedCharge = chargeService.saveAndFlush(charge.getChargeOrigin());
charge.setChargeOrigin(deactivatedCharge);
chargeService.saveOneCharge(charge)

但在这种情况下,我的服务器不会抛出异常,并挂起。

在寻找答案的同时,我重新编写了代码,以下是实际项目的一部分:

@Transactional
private void methodWithMainTransaction() {

        for (Charge charge: charges) {
            chargeService.changeChargeActivation(charges);
        }

服务方式:

@Override
@Transactional(propagation = Propagation.REQUIRES_NEW)
public Charge changeChargeActivation(Charge charge) {
    Charge chargeOrigin = charge.getChargeOrigin();
    if (chargeOrigin != null) {
        chargeOrigin.setIsActive(!chargeOrigin.getIsActive());
        chargesRepository.saveAndFlush(chargeOrigin);
    }
    charge.setIsActive(!charge.getIsActive());
    return chargesRepository.saveAndFlush(one);
}

chargesRepository.saveAndFlush(chargeOrigin);
