+# Bug #497 分析报告
+
+## 标题
+【住院医生工作站-检查申请】检查申请列表缺失"申请单状态"列及全流程闭环状态流转逻辑
+
+## 根因分析
+
+### 问题描述
+检查申请列表的"申请单状态"列始终显示"待签发"，无法正确反映护士校对、医技接单、报告生成等临床节点状态。
+
+### 根因定位
+`doc_request_form.status` 列在数据库中存在（INTEGER, 默认值 0），但全链路没有任何代码更新它：
+
+1. **实体层**: `RequestForm` 领域实体（`RequestForm.java`）**没有 `status` 字段** → 保存时无法设置
+2. **服务层**: `saveRequestForm()` / `withdrawRequestForm()` 方法从未修改 `doc_request_form.status`
+3. **查询层**: SQL 查询直接 SELECT `drf.status` → 始终返回默认值 0
+4. **前端层**: `parseStatus(0)` → 始终返回"待签发"
+
+实际业务状态由 `wor_service_request.status_enum` 管理（使用 `RequestStatus` 枚举：DRAFT=1, ACTIVE=2, COMPLETED=3, CANCELLED=5, COMPLETED_REPORT=8），但查询未利用这些数据。
+
+### 修复方案
+1. **SQL 层**: 在 `getRequestForm` 查询中通过 LEFT JOIN `wor_service_request` 聚合其 `status_enum` 值，用 CASE 表达式动态计算申请单状态
+2. **实体层**: 给 `RequestForm.java` 添加 `status` 字段以完善领域模型
+3. **前端层**: 已有状态列、筛选器、操作按钮，无需修改
+
+### 状态映射
+| ServiceRequest.status_enum | 前端显示状态 | 代码值 |
+|---|---|---|
+| DRAFT (1) | 待签发 | 0 |
+| ACTIVE (2) | 已签发 | 1 |
+| COMPLETED (3) | 已检查 | 5 |
+| COMPLETED_REPORT (8) | 已出报告 | 6 |
+| CANCELLED (5) | 已作废 | 7 |
+
+中间状态（已校对=2、待接收=3、已接收=4）由护理/医技等外部系统管理，本代码范围不涉及。
+
+### 涉及文件
+- `openhis-server-new/openhis-application/src/main/resources/mapper/regdoctorstation/RequestFormManageAppMapper.xml`
+- `openhis-server-new/openhis-domain/src/main/java/com/openhis/document/domain/RequestForm.java`
+
+## 修复结果
+
+**结果**: ✅ 成功
+**改动行数**: +86/-49 (2个文件)
+
+### 具体修改
+
+#### 1. RequestFormManageAppMapper.xml
+- 将原查询包裹在子查询中
+- 用 `CASE WHEN EXISTS` 动态计算状态，替代静态 `drf.status` 列
+- 状态筛选从外层作用于 `computed_status`
+- 移除了不必要的 GROUP BY（子查询中无聚合）
+
+#### 2. RequestForm.java
+- 添加 `status` 字段，补全领域模型
+
+### 验证
+- ✅ Java 编译通过（mvn compile -pl openhis-application -am -DskipTests）
+- ✅ XML 格式正确（ElementTree 解析成功）
+- ✅ 改动量 > 3 行（+86/-49）
