/**
|
||||
* 医嘱业务实现
|
||||
*
|
||||
* 主要改动：
|
||||
* 1. 为“待写病历”列表查询加入分页（默认 1 页 20 条）并使用 {@link PageHelper} 只查询必要列，
|
||||
* 防止一次性拉取全部门诊订单导致前端加载时间 > 2 秒。
|
||||
* 2. 将查询条件抽取为 {@link OrderMainExample}（示例），仅过滤出状态为 {@link OrderStatus#PENDING_MEDICAL_RECORD}
|
||||
* 的记录，避免全表扫描。
|
||||
* 修复 Bug #505：在药房已发药后，护士不能再执行退回操作。
|
||||
* 通过在业务层校验状态并回滚相关明细状态实现。
|
||||
*
|
||||
* 其它历史修复说明保持不变。
|
||||
* 新增：在发药后同步更新发药汇总单（OrderMain）中的发药数量、金额等统计信息，解决 Bug #503
|
||||
* 【住院发退药】发药明细与发药汇总单数据触发时机不一致，存在业务脱节风险。
|
||||
*
|
||||
* 修复 Bug #506：门诊诊前退号后，数据库多表状态值变更与 PRD 定义不符。
|
||||
* 退号（取消挂号）应同时将 OrderMain、OrderDetail、ScheduleSlot 等相关表的状态统一设置为
|
||||
* PRD 中约定的 “已取消”(OrderStatus.CANCELLED)。此前仅更新了 OrderMain，导致
|
||||
* 明细仍保持原有状态，业务查询出现不一致。下面的 {@code cancelOrder} 方法在同一事务内
|
||||
* 完整同步状态，确保所有关联表状态与 PRD 定义保持一致。
