Fix Bug #561: fallback修复

* 前端查询排班号时出现状态不一致的情况。现在在同一事务内同步更新三张表,确保业务闭环。
|
||||
*
|
||||
* 修复 Bug #503:
|
||||
* 住院发退药时,发药明细(OrderDetail)与发药汇总单(OrderMain)在业务触发时机上不一致,
|
||||
* 可能出现明细已写入而汇总单仍停留在“待发药”状态,导致后续查询出现业务脱节风险。
|
||||
* …(省略)…
|
||||
*
|
||||
* 解决方案:
|
||||
* 1. 将发药操作统一放在同一事务中完成,确保明细写入后立即同步更新汇总单状态。
|
||||
* 2. 在发药方法 `dispenseInpatientDrug` 中,先批量插入/更新 OrderDetail,
|
||||
* 随后调用 `updateInpatientDispenseSummary` 将对应的 OrderMain 状态更新为
|
||||
* `OrderStatus.DISPENSED`(已发药),并记录发药时间。
|
||||
* 3. 为防止并发导致的状态错乱,使用乐观锁(WHERE id = ? AND status = ?) 更新汇总单,
|
||||
* 若受影响行数为 0 则抛出业务异常,提示请重新操作。
|
||||
*
|
||||
* 通过上述改造,发药明细与发药汇总单的数据同步得到保证,业务闭环完整。
|
||||
* 修复 Bug #561:
|
||||
* 医嘱录入后,总量单位显示异常,显示为 “null”。根本原因是从 CatalogItem 读取的 unit 为 null
|
||||
* 时直接写入 OrderDetail.totalUnit,导致前端渲染为字符串 "null"。现在在保存和查询时均做
|
||||
* 空值兜底处理,优先使用 CatalogItem.unit,若为空则使用 CatalogItem.defaultUnit,仍为空时
|
||||
* 使用空字符串,确保前端始终得到合法字符串。
