如何将subscribeMeeting和updateWrapper的操作放到同一个事务中

可以使用@Transactional注解来开启事务，将subscribeMeeting和updateWrapper的操作放到同一个事务中，以保证在两个表中的数据操作是原子性的，一旦出现异常，事务就会回滚，保证数据一致性和完整性。优化后的代码如下：

@ApiOperation("编辑会议报名信息")
@Transactional
@PostMapping("/updateMeetingRegistration")
public AjaxResult updateMeetingRegistration(@RequestBody MeetingUpdateInfo meeting){
    String subscribeId = meeting.getSubscribeId();
    if (StringUtils.isBlank(subscribeId)) {
        return AjaxResult.error("预约id不能为空!");
    }
    //更新subscribe_meeting表
    SubscribeMeeting subscribeMeeting = SubscribeMeeting.builder()
            .subscribeId(subscribeId)
            .customName(meeting.getCustomName())
            .customIdNumber(meeting.getCustomIdNumber())
            .regionName(meeting.getRegionName())
            .shopName(meeting.getShopName())
            .ticket(meeting.getTicket())
            .meetingRemark(meeting.getMeetingRemark())
            .build();
    subscribeMeetingService.updateById(subscribeMeeting);
    //更新subscribe_detail表
    UpdateWrapper<SubscribeDetail> updateWrapper = new UpdateWrapper<>();
    updateWrapper.lambda()
            .set(SubscribeDetail::getCustomPhone, meeting.getCustomPhone())
            .set(SubscribeDetail::getCustomType, meeting.getCustomType())
            .set(SubscribeDetail::getLeaderName, meeting.getLeaderName())
            .eq(SubscribeDetail::getSubscribeId, subscribeId);
    subscribeDetailService.update(updateWrapper);
    return AjaxResult.success();
}
