java引发异常时回滚更改

在触发电子邮件和更新数据库中的数据之前，我有一个实现（执行一些操作并将对象保存在数据库中）

BATCH\u JOB\u EXECUTION\u CONTEXT

表

执行此操作时，应用程序正在引发异常。请在下面查找例外情况

    2019-10-01 00:00:01,379 [pool-3-thread-1]  INFO core.batch.tasklet.RemoveSpringBatchHistoryTasklet:  70 - Remove the Spring Batch history before the 9/1/19 12:00 AM

即使抛出异常，它也会发送电子邮件和数据库表中更新的错误信息

请在下面找到我的代码

@Override
@Transactional
public void approve(Long id, ClaimApproval claimApproval) {
    Claim claim = claimRepository.findOne(id);

             ClaimAssignment claimAssignment = claim.findNextPendingAssignment();

             claim.incrementApprovalLevel();
             claim.addHistory(historyRecordFor(claimApproval, HistoryAction.APPROVED));
             claimRepository.save(claim);
             if (!areAllAssignmentsApproved(claim))
                 emailDispatcherService.notifyNextClaimApprover(claim, assignmentService.getNextLevelApprovers(claim));  //Exception is throws here, but previous statements are executed properly and that should not happen when exception thrown.


}

例外从何而来？显示完整的stacktrace。@Andreas-使用完整的stacktrace更新。更好的方法不是将作业监视侦听器添加到作业定义中，然后在侦听器中插入通知程序，以便在作业完成时使用该通知程序发送电子邮件。然后，您还可以在完全知道作业本身没有锁定表的情况下，通过通知程序执行DB工作。。参考：这不是stacktrace，请参阅
