Fix Bug #505: fallback修复
This commit is contained in:

|
||||
* 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。
|
||||
*
|
||||
* 关键修复点（Bug #506）：
|
||||
* 门诊诊前退号后，涉及 OrderMain、OrderDetail、ScheduleSlot、SchedulePool、RefundLog
|
||||
* 等多表的状态更新未严格遵循产品需求（PRD）。原实现使用了错误的状态枚举，导致
|
||||
* 数据库中状态值与前端展示、统计口径不一致。此处统一使用 PRD 定义的状态：
|
||||
* • OrderMain -> OrderStatus.CANCELLED
|
||||
* • OrderDetail -> OrderStatus.CANCELLED
|
||||
* • ScheduleSlot-> ScheduleSlotStatus.AVAILABLE
|
||||
* • SchedulePool-> SchedulePoolStatus.AVAILABLE
|
||||
* • RefundLog -> RefundStatus.SUCCESS
|
||||
*
|
||||
* 同时保证在同一事务内完成所有表的更新，防止部分成功、部分失败导致数据不一致。
|
||||
* 关键修复点（Bug #505）：
|
||||
* 当药品已由药房发药（DispenseStatus = DISPENSED）时，护士在“医嘱校对”模块仍可以
|
||||
* 执行“退回”操作，导致状态回滚错误。现在在执行退回前加入发药状态校验，
|
||||
* 若已发药则抛出 BusinessException，阻止退回。
