Spring事务失效七个场景

１、数据库引擎不支持事务

２、不支持事务（事务传播开启(propagation = Propagation.NOT_SUPPORTED））

３、方法不是 publi修饰

４、没有被 Spring 管理

５、数据库引擎不支持事务

６、自身调用问题

之前＠Transactional加在内部调用方法上，事务失效－－－－重点记录

@Override
public void dataHandler() {

    List informedList;

 List renewedList;

 int informedListSize = 0;
 int renewedListSize = 0;

 //处理已通知数据
 do {
        informedList = doInformedData();
 informedListSize += informedList.size();
 } while (!informedList.isEmpty() && informedList.size() == handlerStep);

 //处理已续期数据
 do {
        renewedList = doRenewedData();
 renewedListSize += renewedList.size();
 } while (!renewedList.isEmpty() && renewedList.size() == handlerStep);

 if (informedListSize > 0) {
        String message = String.format("定时任务常设协议授权状态修改结束，用户状态从已通知修改为待续费完成%d单", informedListSize);
 log.info(message);
 monitorInterface.sendScheduleNormalNotice(message, true);
 }

    if (renewedListSize > 0) {
        String message = String.format("定时任务常设协议授权状态修改结束，用户状态从已续费修改为未到期完成%d单", renewedListSize);
 log.info(message);
 monitorInterface.sendScheduleNormalNotice(message, true);
 }

}


@Transactional
public List doInformedData() {
    List list = standingAuthorityDAO.getListByStatusAndNoticeEndDate(StandingAuthorityEnum.Informed.getCode(), getDate(), handlerStep);
 list.forEach(standingAuthorityPO -> {
        standingAuthorityPO.setStatus(StandingAuthorityEnum.ToBeRenewed.getCode());
 standingAuthorityPO.setProcessTime(LocalDateTime.now());
 standingAuthorityDAO.updateById(standingAuthorityPO);
 saveStandingAuthorityFlow(StandingAuthorityFlowEnum.ToBeRenewed.getCode(), standingAuthorityPO);
 });
 return list;
}


@Transactional
public List doRenewedData() {
    List list = standingAuthorityDAO.getListByStatus(StandingAuthorityEnum.Renewed.getCode(), handlerStep);
 list.forEach(standingAuthorityPO -> {
        standingAuthorityPO.setStatus(StandingAuthorityEnum.NotExpired.getCode());
 standingAuthorityPO.setProcessTime(LocalDateTime.now());
 standingAuthorityDAO.updateById(standingAuthorityPO);
 saveStandingAuthorityFlow(StandingAuthorityFlowEnum.Finished.getCode(), standingAuthorityPO);
 });
 return list;
}


@Transactional
public void saveStandingAuthorityFlow(Integer status, StandingAuthorityPO standingAuthorityPO) {
    StandingAuthorityFlowPO standingAuthorityFlowPO = new StandingAuthorityFlowPO();
 BeanUtil.copyProperties(standingAuthorityPO, standingAuthorityFlowPO);
 standingAuthorityFlowPO.setOptType(status);
 standingAuthorityFlowDAO.save(standingAuthorityFlowPO);
}

下面是正确使用：

@Override
@Transactional
public void dataHandler() {

    List informedList;

 List renewedList;

 int informedListSize = 0;
 int renewedListSize = 0;

 //处理已通知数据
 do {
        informedList = doInformedData();
 informedListSize += informedList.size();
 } while (!informedList.isEmpty() && informedList.size() == handlerStep);

 //处理已续期数据
 do {
        renewedList = doRenewedData();
 renewedListSize += renewedList.size();
 } while (!renewedList.isEmpty() && renewedList.size() == handlerStep);

 if (informedListSize > 0) {
        String message = String.format("定时任务常设协议授权状态修改结束，用户状态从已通知修改为待续费完成%d单", informedListSize);
 log.info(message);
 monitorInterface.sendScheduleNormalNotice(message, true);
 }

    if (renewedListSize > 0) {
        String message = String.format("定时任务常设协议授权状态修改结束，用户状态从已续费修改为未到期完成%d单", renewedListSize);
 log.info(message);
 monitorInterface.sendScheduleNormalNotice(message, true);
 }

}

public List doInformedData() {
    List list = standingAuthorityDAO.getListByStatusAndNoticeEndDate(StandingAuthorityEnum.Informed.getCode(), getDate(), handlerStep);
 list.forEach(standingAuthorityPO -> {
        standingAuthorityPO.setStatus(StandingAuthorityEnum.ToBeRenewed.getCode());
 standingAuthorityPO.setProcessTime(LocalDateTime.now());
 standingAuthorityDAO.updateById(standingAuthorityPO);
 saveStandingAuthorityFlow(StandingAuthorityFlowEnum.ToBeRenewed.getCode(), standingAuthorityPO);
 });
 return list;
}

public List doRenewedData() {
    List list = standingAuthorityDAO.getListByStatus(StandingAuthorityEnum.Renewed.getCode(), handlerStep);
 list.forEach(standingAuthorityPO -> {
        standingAuthorityPO.setStatus(StandingAuthorityEnum.NotExpired.getCode());
 standingAuthorityPO.setProcessTime(LocalDateTime.now());
 standingAuthorityDAO.updateById(standingAuthorityPO);
 saveStandingAuthorityFlow(StandingAuthorityFlowEnum.Finished.getCode(), standingAuthorityPO);
 });
 return list;
}

public void saveStandingAuthorityFlow(Integer status, StandingAuthorityPO standingAuthorityPO) {
    StandingAuthorityFlowPO standingAuthorityFlowPO = new StandingAuthorityFlowPO();
 BeanUtil.copyProperties(standingAuthorityPO, standingAuthorityFlowPO);
 standingAuthorityFlowPO.setOptType(status);
 standingAuthorityFlowDAO.save(standingAuthorityFlowPO);
}

７、异常问题

异常问题有两个：

１、异常被吃掉没有抛出异常，事务会失效

２、异常捕捉后抛出非Runtime异常，事务会失效－－－－解决加上@Transactional(rollbackFor = Exception.class)注解
