# 项目详情风险明细统一导出后端 Implementation Plan
|
||
|
||
> **For agentic workers:** REQUIRED: Use superpowers:subagent-driven-development (if subagents available) or superpowers:executing-plans to implement this plan. Steps use checkbox (`- [ ]`) syntax for tracking.
|
||
>
|
||
> 仓库约束：当前仓库明确禁止开启 subagent，执行时统一使用 `superpowers:executing-plans`。
|
||
|
||
**Goal:** 为项目详情风险明细新增统一后端导出能力，输出一个包含 `涉疑交易明细`、`员工负面征信信息`、`异常账户人员信息` 三个 sheet 的 Excel 文件。
|
||
|
||
**Architecture:** 复用现有涉疑交易导出查询口径，补充员工负面征信的非分页导出查询，再由后端统一组装工作簿并输出响应流。异常账户人员信息本轮不开发真实查询，只输出固定表头的空白 sheet，保证导出文件结构稳定。
|
||
|
||
**Tech Stack:** Java 21, Spring Boot 3, MyBatis XML, EasyExcel, JUnit 5, Mockito

|
||
|
||
## Task 1: 锁定统一导出接口契约
|
||
|
||
**Files:**
|
||
|
||
- Modify: `ccdi-project/src/test/java/com/ruoyi/ccdi/project/controller/CcdiProjectOverviewControllerContractTest.java`
|
||
- Modify: `ccdi-project/src/test/java/com/ruoyi/ccdi/project/controller/CcdiProjectOverviewControllerTest.java`
|
||
|
||
- [ ] **Step 1: 先写控制器契约测试**
|
||
|
||
在 `CcdiProjectOverviewControllerContractTest` 中新增一个测试，断言新方法：
|
||
|
||
```java
|
||
Method method = controllerClass.getMethod(
|
||
"exportRiskDetails",
|
||
HttpServletResponse.class,
|
||
Long.class
|
||
);
|
||
PostMapping postMapping = method.getAnnotation(PostMapping.class);
|
||
assertEquals("/risk-details/export", postMapping.value()[0]);
|
||
```
|
||
|
||
- [ ] **Step 2: 补控制器单测，先让它失败**
|
||
|
||
在 `CcdiProjectOverviewControllerTest` 中新增测试，约束控制器只做委托：
|
||
|
||
```java
|
||
MockHttpServletResponse response = new MockHttpServletResponse();
|
||
controller.exportRiskDetails(response, 40L);
|
||
verify(overviewService).exportRiskDetails(same(response), same(40L));
|
||
```
|
||
|
||
- [ ] **Step 3: 运行后端定向测试，确认失败点正确**
|
||
|
||
Run:
|
||
|
||
```bash
|
||
mvn -pl ccdi-project -Dtest=CcdiProjectOverviewControllerContractTest,CcdiProjectOverviewControllerTest test
|
||
```
|
||
|
||
Expected:
|
||
|
||
- FAIL，提示控制器缺少 `exportRiskDetails` 方法或签名不匹配
|
||
|
||
- [ ] **Step 4: 最小化补齐控制器方法签名**
|
||
|
||
在 `CcdiProjectOverviewController.java` 中增加方法骨架：
|
||
|
||
```java
|
||
@PostMapping("/risk-details/export")
|
||
@Operation(summary = "导出风险明细")
|
||
@PreAuthorize("@ss.hasPermi('ccdi:project:query')")
|
||
public void exportRiskDetails(HttpServletResponse response, Long projectId) {
|
||
overviewService.exportRiskDetails(response, projectId);
|
||
}
|
||
```
|
||
|
||
- [ ] **Step 5: 重新运行控制器测试**
|
||
|
||
Run:
|
||
|
||
```bash
|
||
mvn -pl ccdi-project -Dtest=CcdiProjectOverviewControllerContractTest,CcdiProjectOverviewControllerTest test
|
||
```
|
||
|
||
Expected:
|
||
|
||
- PASS
|
||
|
||
- [ ] **Step 6: 提交本任务**
|
||
|
||
```bash
|
||
git add ccdi-project/src/main/java/com/ruoyi/ccdi/project/controller/CcdiProjectOverviewController.java \
|
||
ccdi-project/src/test/java/com/ruoyi/ccdi/project/controller/CcdiProjectOverviewControllerContractTest.java \
|
||
ccdi-project/src/test/java/com/ruoyi/ccdi/project/controller/CcdiProjectOverviewControllerTest.java
|
||
git commit -m "补充风险明细统一导出接口契约"
|
||
```
|
||
|
||
## Task 2: 补齐员工负面征信导出数据链路
|
||
|
||
**Files:**
|
||
|
||
- Create: `ccdi-project/src/main/java/com/ruoyi/ccdi/project/domain/excel/CcdiProjectEmployeeCreditNegativeExcel.java`
|
||
- Modify: `ccdi-project/src/main/java/com/ruoyi/ccdi/project/service/ICcdiProjectOverviewService.java`
|
||
- Modify: `ccdi-project/src/main/java/com/ruoyi/ccdi/project/service/impl/CcdiProjectOverviewServiceImpl.java`
|
||
- Modify: `ccdi-project/src/main/java/com/ruoyi/ccdi/project/mapper/CcdiProjectOverviewMapper.java`
|
||
- Modify: `ccdi-project/src/main/resources/mapper/ccdi/project/CcdiProjectOverviewMapper.xml`
|
||
- Modify: `ccdi-project/src/test/java/com/ruoyi/ccdi/project/service/impl/CcdiProjectOverviewServiceEmployeeCreditNegativeTest.java`
|
||
- Modify: `ccdi-project/src/test/java/com/ruoyi/ccdi/project/mapper/CcdiProjectOverviewMapperSqlTest.java`
|
||
|
||
- [ ] **Step 1: 先写 Mapper SQL 断言**
|
||
|
||
在 `CcdiProjectOverviewMapperSqlTest` 中新增对 `selectEmployeeCreditNegativeList` 的断言：
|
||
|
||
```java
|
||
String exportSql = extractSelect(xml, "selectEmployeeCreditNegativeList");
|
||
assertTrue(exportSql.contains("from ccdi_project_overview_employee_result"));
|
||
assertTrue(exportSql.contains("inner join ccdi_credit_negative_info"));
|
||
assertTrue(exportSql.contains("order by neg.query_date desc, neg.person_id asc"));
|
||
```
|
||
|
||
- [ ] **Step 2: 再写服务层失败测试**
|
||
|
||
在 `CcdiProjectOverviewServiceEmployeeCreditNegativeTest` 中新增两个测试：
|
||
|
||
- 导出时项目存在且能返回 `List<CcdiProjectEmployeeCreditNegativeExcel>`
|
||
- 项目不存在时抛出 `ServiceException`
|
||
|
||
示例断言：
|
||
|
||
```java
|
||
List<CcdiProjectEmployeeCreditNegativeExcel> rows = service.exportEmployeeCreditNegative(40L);
|
||
assertEquals("李四", rows.getFirst().getPersonName());
|
||
verify(overviewMapper).selectEmployeeCreditNegativeList(40L);
|
||
```
|
||
|
||
- [ ] **Step 3: 运行测试确认失败**
|
||
|
||
Run:
|
||
|
||
```bash
|
||
mvn -pl ccdi-project -Dtest=CcdiProjectOverviewMapperSqlTest,CcdiProjectOverviewServiceEmployeeCreditNegativeTest test
|
||
```
|
||
|
||
Expected:
|
||
|
||
- FAIL，提示缺少 Mapper select 或服务方法
|
||
|
||
- [ ] **Step 4: 实现最小导出链路**
|
||
|
||
按以下顺序补代码：
|
||
|
||
1. 创建 `CcdiProjectEmployeeCreditNegativeExcel.java`
|
||
2. 在 `ICcdiProjectOverviewService` 增加：
|
||
|
||
```java
|
||
List<CcdiProjectEmployeeCreditNegativeExcel> exportEmployeeCreditNegative(Long projectId);
|
||
```
|
||
|
||
3. 在 `CcdiProjectOverviewMapper.java` 增加：
|
||
|
||
```java
|
||
List<CcdiProjectEmployeeCreditNegativeItemVO> selectEmployeeCreditNegativeList(@Param("projectId") Long projectId);
|
||
```
|
||
|
||
4. 在 `CcdiProjectOverviewMapper.xml` 新增非分页导出 SQL
|
||
5. 在 `CcdiProjectOverviewServiceImpl` 中增加映射方法，把 `ItemVO` 转为 `Excel` 行对象
|
||
|
||
- [ ] **Step 5: 重新运行定向测试**
|
||
|
||
Run:
|
||
|
||
```bash
|
||
mvn -pl ccdi-project -Dtest=CcdiProjectOverviewMapperSqlTest,CcdiProjectOverviewServiceEmployeeCreditNegativeTest test
|
||
```
|
||
|
||
Expected:
|
||
|
||
- PASS
|
||
|
||
- [ ] **Step 6: 提交本任务**
|
||
|
||
```bash
|
||
git add ccdi-project/src/main/java/com/ruoyi/ccdi/project/domain/excel/CcdiProjectEmployeeCreditNegativeExcel.java \
|
||
ccdi-project/src/main/java/com/ruoyi/ccdi/project/service/ICcdiProjectOverviewService.java \
|
||
ccdi-project/src/main/java/com/ruoyi/ccdi/project/service/impl/CcdiProjectOverviewServiceImpl.java \

ccdi-project/src/main/resources/mapper/ccdi/project/CcdiProjectOverviewMapper.xml \
|
||
ccdi-project/src/test/java/com/ruoyi/ccdi/project/service/impl/CcdiProjectOverviewServiceEmployeeCreditNegativeTest.java \
|
||
ccdi-project/src/test/java/com/ruoyi/ccdi/project/mapper/CcdiProjectOverviewMapperSqlTest.java
|
||
git commit -m "补充风险明细负面征信导出链路"
|
||
```
|
||
|
||
## Task 3: 实现统一工作簿导出器
|
||
|
||
**Files:**
|
||
|
||
- Create: `ccdi-project/src/main/java/com/ruoyi/ccdi/project/service/impl/CcdiProjectRiskDetailWorkbookExporter.java`
|
||
- Create: `ccdi-project/src/test/java/com/ruoyi/ccdi/project/service/impl/CcdiProjectRiskDetailWorkbookExporterTest.java`
|
||
|
||
- [ ] **Step 1: 先写工作簿测试**
|
||
|
||
新增 `CcdiProjectRiskDetailWorkbookExporterTest`，覆盖：
|
||
|
||
- 工作簿固定包含 3 个 sheet
|
||
- 顺序为 `涉疑交易明细`、`员工负面征信信息`、`异常账户人员信息`
|
||
- 第三个 sheet 只有表头
|
||
|
||
建议使用 `ByteArrayOutputStream + EasyExcel.read/POI` 读取结果验证。
|
||
|
||
关键断言示例：
|
||
|
||
```java
|
||
assertEquals("涉疑交易明细", workbook.getSheetAt(0).getSheetName());
|
||
assertEquals("员工负面征信信息", workbook.getSheetAt(1).getSheetName());
|
||
assertEquals("异常账户人员信息", workbook.getSheetAt(2).getSheetName());
|
||
assertEquals("账号", workbook.getSheetAt(2).getRow(0).getCell(0).getStringCellValue());
|
||
```
|
||
|
||
- [ ] **Step 2: 运行测试确认失败**
|
||
|
||
Run:
|
||
|
||
```bash
|
||
mvn -pl ccdi-project -Dtest=CcdiProjectRiskDetailWorkbookExporterTest test
|
||
```
|
||
|
||
Expected:
|
||
|
||
- FAIL，提示缺少导出器类
|
||
|
||
- [ ] **Step 3: 写最小工作簿导出器**
|
||
|
||
创建 `CcdiProjectRiskDetailWorkbookExporter`，职责仅限：
|
||
|
||
- 写入 `涉疑交易明细` sheet
|
||
- 写入 `员工负面征信信息` sheet
|
||
- 写入仅含表头的 `异常账户人员信息` sheet
|
||
- 统一设置文件名和响应头
|
||
|
||
不要在这个类里做项目校验或数据库查询。
|
||
|
||
- [ ] **Step 4: 重新运行工作簿测试**
|
||
|
||
Run:
|
||
|
||
```bash
|
||
mvn -pl ccdi-project -Dtest=CcdiProjectRiskDetailWorkbookExporterTest test
|
||
```
|
||
|
||
Expected:
|
||
|
||
- PASS
|
||
|
||
- [ ] **Step 5: 提交本任务**
|
||
|
||
```bash
|
||
git add ccdi-project/src/main/java/com/ruoyi/ccdi/project/service/impl/CcdiProjectRiskDetailWorkbookExporter.java \
|
||
ccdi-project/src/test/java/com/ruoyi/ccdi/project/service/impl/CcdiProjectRiskDetailWorkbookExporterTest.java
|
||
git commit -m "补充风险明细多sheet导出器"
|
||
```
|
||
|
||
## Task 4: 串起服务实现并完成后端验证
|
||
|
||
**Files:**
|
||
|
||
- Modify: `ccdi-project/src/main/java/com/ruoyi/ccdi/project/service/ICcdiProjectOverviewService.java`
|
||
- Modify: `ccdi-project/src/main/java/com/ruoyi/ccdi/project/service/impl/CcdiProjectOverviewServiceImpl.java`
|
||
- Modify: `ccdi-project/src/test/java/com/ruoyi/ccdi/project/controller/CcdiProjectOverviewControllerTest.java`
|
||
- Modify: `docs/reports/implementation/2026-03-30-project-detail-risk-details-unified-export-backend-implementation.md`
|
||
|
||
- [ ] **Step 1: 先写服务层失败测试**
|
||
|
||
如果现有 `CcdiProjectOverviewServiceImplTest` 更合适，就在其中新增；否则新建一个导出专用测试类。至少覆盖：
|
||
|
||
- 服务内部调用现有 `exportSuspiciousTransactions`
|
||
- 服务调用 `exportEmployeeCreditNegative`
|
||
- 服务把两份真实数据交给 `CcdiProjectRiskDetailWorkbookExporter`
|
||
- 项目不存在时直接失败
|
||
|
||
- [ ] **Step 2: 运行服务测试确认失败**
|
||
|
||
Run:
|
||
|
||
```bash
|
||
mvn -pl ccdi-project -Dtest=CcdiProjectOverviewServiceImplTest,CcdiProjectOverviewControllerTest test
|
||
```
|
||
|
||
Expected:
|
||
|
||
- FAIL，提示 `exportRiskDetails` 尚未真正实现
|
||
|
||
- [ ] **Step 3: 实现统一导出主流程**
|
||
|
||
在 `CcdiProjectOverviewServiceImpl` 中补齐：
|
||
|
||
```java
|
||
public void exportRiskDetails(HttpServletResponse response, Long projectId) {
|
||
ensureProjectExists(projectId);
|
||
CcdiProjectSuspiciousTransactionQueryDTO queryDTO = new CcdiProjectSuspiciousTransactionQueryDTO();
|
||
queryDTO.setProjectId(projectId);
|
||
queryDTO.setSuspiciousType("ALL");
|
||
List<CcdiProjectSuspiciousTransactionExcel> suspiciousRows = exportSuspiciousTransactions(queryDTO);
|
||
List<CcdiProjectEmployeeCreditNegativeExcel> creditRows = exportEmployeeCreditNegative(projectId);
|
||
workbookExporter.export(response, projectId, suspiciousRows, creditRows);
|
||
}
|
||
```
|
||
|
||
- [ ] **Step 4: 跑完整后端回归**
|
||
|
||
Run:
|
||
|
||
```bash
|
||
mvn -pl ccdi-project -Dtest=CcdiProjectOverviewControllerTest,CcdiProjectOverviewControllerContractTest,CcdiProjectOverviewServiceEmployeeCreditNegativeTest,CcdiProjectRiskDetailWorkbookExporterTest,CcdiProjectOverviewMapperSqlTest test
|
||
```
|
||
|
||
Expected:
|
||
|
||
- PASS
|
||
|
||
可选补充：
|
||
|
||
```bash
|
||
mvn -pl ccdi-project test
|
||
```
|
||
|
||
- [ ] **Step 5: 写后端实施记录**
|
||
|
||
在 `docs/reports/implementation/2026-03-30-project-detail-risk-details-unified-export-backend-implementation.md` 中记录：
|
||
|
||
- 新增接口与方法
|
||
- 多 sheet 工作簿实现
|
||
- 员工负面征信导出链路
|
||
- 异常账户空白 sheet 处理
|
||
- 实际执行的测试命令与结果
|
||
|
||
- [ ] **Step 6: 提交本任务**
|
||
|
||
```bash
|
||
git add ccdi-project/src/main/java/com/ruoyi/ccdi/project/service/ICcdiProjectOverviewService.java \
|
||
ccdi-project/src/main/java/com/ruoyi/ccdi/project/service/impl/CcdiProjectOverviewServiceImpl.java \
|
||
ccdi-project/src/test/java/com/ruoyi/ccdi/project/controller/CcdiProjectOverviewControllerTest.java \
|
||
docs/reports/implementation/2026-03-30-project-detail-risk-details-unified-export-backend-implementation.md
|
||
git commit -m "完成风险明细统一导出后端实现"
|
||
```
|
||
|
||
## Final Verification
|
||
|
||
- [ ] 运行：
|
||
|
||
```bash
|
||
mvn -pl ccdi-project -Dtest=CcdiProjectOverviewControllerTest,CcdiProjectOverviewControllerContractTest,CcdiProjectOverviewServiceEmployeeCreditNegativeTest,CcdiProjectRiskDetailWorkbookExporterTest,CcdiProjectOverviewMapperSqlTest test
|
||
```
|
||
|
||
- [ ] 确认导出接口路径为 `POST /ccdi/project/overview/risk-details/export`
|
||
- [ ] 确认导出文件包含 3 个 sheet，第三个 sheet 只有表头
|
||
- [ ] 确认旧的 `/suspicious-transactions/export` 仍保留，避免影响其他调用方
|
||
