输入：

1.我使用的是一个服务器集群结构，其中包含1个LEADER和2个FOLLOWERS。
1.节点结构x1c 0d1x
保存支付方法：

@Override
@UseBookmark
@Transactional(rollbackFor = Exception.class, propagation = Propagation.REQUIRED)
public void addEmploymentPayout(EmploymentPayoutDTO payoutDto, String employmentId) {
    try {
        // Map
        var payout = dozerMapper.map(payoutDto, EmploymentPayout.class);

        // Save
        var employment = profileService.findEmploymentByUuid(employmentId);

        var container = employmentPayoutContainerRepository.getContainerIfExist(employmentId)
                                                           .orElse(new EmploymentPayoutContainer());
        container.setEmployment(employment);

        var payouts = Optional.ofNullable(container.getEmploymentPayouts())
                              .orElse(new ArrayList<>());
        payouts.add(payout);
        container.setEmploymentPayouts(payouts);
        employmentPayoutContainerRepository.save(container);

        // employmentPayout.setEmploymentPayoutContainer(container);
        // employmentPayoutRepository.save(payout);
        // employmentPayoutRepository.save(employmentPayout, 2);
    } catch (Exception e) {
        LOG.error(ExceptionUtils.getStackTrace(e));
    }
}

字符串
方法getAllPureEmploymentsByProfileId：

@Query("MATCH (p:Profile) WHERE p.uuid=$profileId "
    + "MATCH (p)-[:HAS_PROFILE_EMPLOYMENT_CONTAINER]->(pec:ProfileEmploymentContainer) "
    + "MATCH path = (pec)-[:USES_PROFILE_EMPLOYMENT]-(pe:ProfileEmployment) RETURN pec, path")
ProfileEmploymentContainer getAllPureEmploymentsByProfileId( @Param("profileId") String profileId);

型

说明

保存（添加）新的EmploymentPayout（addEmploymentPayout）后，当我尝试加载全部或部分路径（getAllPureEmploymentsByProfileId）时，我得到此错误。但重新启动服务器后错误消失。你能帮助我理解我做错了什么吗？多谢了！

我尝试添加这些注解，但没有帮助：

  • @UseBookmark个
  • @Transactional(rollbackFor = Exception.class, propagation = Propagation.REQUIRED)个
    UPD

我没有这个问题与独立（无集群）Neoj 4服务器。

按热度按时间
z4bn682m

z4bn682m1#

我发现了导致这个问题的原因。这是对这个异步方法的调用：

emailService.sendPayoutCreatedEmailAsync(employmentId, payout, userDetails); // fire-and-forget

字符串
上面的方法在addEmploymentPayout之后调用。
这是这个方法的定义，它被称为另一个非ansync方法-sendPayoutCreatedEmail（这个方法调用了存储库方法）：

@Override
public CompletableFuture<Void> sendPayoutCreatedEmailAsync(String employmentId, EmploymentPayoutDTO payout, InfotempUserDetails userDetails) {

    var future = CompletableFuture.runAsync(() -> {
        this.sendPayoutCreatedEmail(employmentId, payout, userDetails);
    });

    return future;
}

型

解决方案：

如果您将异步方法调用更改为来自新线程的调用，则它可以工作（不知道如何工作，但它确实可以工作）。就像这样：

new Thread(() -> {
    emailService.sendPayoutCreatedEmail(employmentId, payout, userDetails);
}).start();
