Fix Bug #575: fallback修复

|
||||
* 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。
|
||||
*
|
||||
* 解决方案:
|
||||
* 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。
|
||||
* 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。
|
||||
* 新增修复(Bug #575):
|
||||
* 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。

|

* 为了修复 Bug #503,整个过程必须在同一个事务中完成:

* 1. 创建并持久化 DispensingSummary(汇总单);
|

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

* 3. 更新 OrderMain、OrderDetail 等相关表的状态;
|

* 4. 如有异常,事务回滚,保证两张表的数据一致性。

* 该方法在事务内完成:
|

* 1. 插入 OrderMain、OrderDetail 等基础数据;
|
||||
* 2. 更新对应的 ScheduleSlot 状态;
|
||||
* 3. **实时累加 SchedulePool.booked_num**(Bug #575 修复点);
