*
|
*
|
||||||
* 解决方案:
|
* 新增修复(Bug #575):
|
||||||
* 1. 将发药业务统一放在同一个 @Transactional 方法中,确保两张表的写入要么全部成功要么全部回滚。
|
* 预约成功后,实时累加 SchedulePool.booked_num,防止出现已预约数未更新的情况。
|
||||||
* 2. 先生成并持久化 DispensingSummary,再生成对应的 DispensingDetail。
|
|
||||||
* 3. 在写入明细前,将明细的状态显式设置为与汇总单相同的状态(如 DISPENSED),避免因默认值导致的不一致。
|
|
||||||
* 4. 完成后统一更新 OrderMain 的发药状态,确保业务层面的状态同步。

* 2. 根据汇总单创建对应的 DispensingDetail(明细),并显式设置状态;
|
* 2. 更新对应的 ScheduleSlot 状态;
|

* 3. 更新 OrderMain、OrderDetail 等相关表的状态;
|
* 3. **实时累加 SchedulePool.booked_num**(Bug #575 修复点);
|
||||||
* 4. 如有异常,事务回滚,保证两张表的数据一致性。

* 4. 其它业务如费用计算、队列排号等。
