*
|
||||
* 修复 Bug #505、#503、#506、#561 等。
|
||||
*
|
||||
* 关键修复点（Bug #503）：
|
||||
* 住院发退药时，发药明细（DispensingDetail）与发药汇总单（OrderMain/OrderDetail）状态的触发时机不一致，
|
||||
* 可能出现明细已标记为已发药，而汇总单仍停留在“待发药”状态，导致业务脱节风险。
|
||||
* 关键修复点（Bug #506）：
|
||||
* 门诊诊前退号后，涉及的多张表（order_main、order_detail、schedule_slot、schedule_pool 等）状态未统一
|
||||
* 与生产环境（PRD）定义不符，导致前端显示状态错误、后续排班冲突等问题。
|
||||
*
|
||||
* 解决思路：
|
||||
* 1. 将发药（包括发药明细写入）与汇总单状态更新放在同一个 @Transactional 方法中，确保原子性。
|
||||
* 2. 在写入 DispensingDetail 后，立即更新对应的 OrderDetail 状态为 {@link DispenseStatus#DISPENSED}，
|
||||
* 并检查同一笔住院医嘱的所有明细是否全部发药，若全部发药则把 OrderMain 状态同步更新为 {@link DispenseStatus#DISPENSED}。
|
||||
* 3. 同时记录发药日志，保持审计完整。
|
||||
*
|
||||
* 该实现消除了明细与汇总单状态不一致的窗口，避免了后续业务（如退药、费用结算）出现异常。
|
||||
* 1. 将退号（退款）业务全部放在同一个 @Transactional 方法中，确保原子性。
|
||||
* 2. 统一使用 {@link OrderStatus#CANCELLED} 作为退号后医嘱主表的状态。
|
||||
* 3. 对应明细表（order_detail）状态同步更新为 {@link OrderStatus#CANCELLED}。
|
||||
* 4. 释放已占用的号源：将 schedule_slot.status 设为 {@link ScheduleSlotStatus#AVAILABLE}，
|
||||
* 并将 schedule_pool.used_count -1（若大于0）以恢复号源库存。
|
||||
* 5. 记录退款日志（refund_log），确保审计完整。
