* 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. 将发药明细与发药汇总的写入统一放在同一个事务中，保证原子性。
|
||||
* 2. 在插入明细后立即计算并写入对应的汇总记录，避免因异步或延迟触发导致的不一致。
|
||||
* 3. 为防止并发导致的重复汇总，使用唯一键（order_main_id + drug_id）在数据库层面做唯一约束，
|
||||
* 并在代码中使用 `INSERT … ON DUPLICATE KEY UPDATE`（MyBatis 中通过 `insertOrUpdate`）的方式
|
||||
* 完成“先插后更新”逻辑。
|
||||
*
|
||||
* 这样可以确保每一次发药操作，明细与汇总始终保持同步，业务风险得到根本消除。
