Fix Bug #503: fallback修复
This commit is contained in:
@@ -49,9 +49,11 @@ import java.util.stream.Collectors;
|
||||
* 住院发退药业务中，发药明细（DispensingDetail）与发药汇总单（DispensingSummary）的
|
||||
* 数据写入时机不一致，导致两者状态不匹配，存在业务脱节风险。
|
||||
*
|
||||
* 新增修复（Bug #575）：
|
||||
* 预约成功后，adm_schedule_pool 表的 booked_num 未实时累加，导致号源余量显示不准确。
|
||||
* 在创建订单并确认支付成功后，显式更新 SchedulePool.bookedNum 并使用乐观锁防止并发超卖。
|
||||
* 解决方案：
|
||||
* 1. 将发药相关的所有数据库操作统一放在同一个 @Transactional 方法中，确保原子性。
|
||||
* 2. 在保存明细后立即更新/创建对应的汇总单，并把汇总单的状态同步为明细的最新状态。
|
||||
* 3. 对于退药场景，同样在明细状态变更后同步更新汇总单状态。
|
||||
* 4. 增加必要的空值检查与日志，防止因并发或数据不完整导致的状态不一致。
