# 流程列表测算利率展示后端实施计划 > **For agentic workers:** REQUIRED: Use superpowers:executing-plans to implement this plan in this repository. Do not use subagents. Steps use checkbox (`- [ ]`) syntax for tracking. **Goal:** 让流程列表接口通过联表 SQL 一次返回测算利率 `calculateRate` 和执行利率 `executeRate`。 **Architecture:** 后端为流程列表新增列表专用返回对象，替换当前直接返回 `LoanPricingWorkflow` 实体分页的方式。Mapper 层新增联表 SQL，以 `loan_pricing_workflow` 为主表，左连接个人和企业模型输出表，并统一产出 `calculateRate` 字段供前端直接消费。 **Tech Stack:** Spring Boot、MyBatis Plus、Lombok、Maven、XML Mapper --- ### Task 1: 建立流程列表专用返回对象 **Files:** - Create: `ruoyi-loan-pricing/src/main/java/com/ruoyi/loanpricing/domain/vo/LoanPricingWorkflowListVO.java` - Modify: `ruoyi-loan-pricing/src/main/java/com/ruoyi/loanpricing/service/ILoanPricingWorkflowService.java` - Modify: `ruoyi-loan-pricing/src/main/java/com/ruoyi/loanpricing/controller/LoanPricingWorkflowController.java` - [ ] **Step 1: 写一个失败测试，约束列表返回对象需要包含测算利率** Create/Test: `ruoyi-loan-pricing/src/test/java/com/ruoyi/loanpricing/domain/vo/LoanPricingWorkflowListVOTest.java` 测试示例： ```java @Test void shouldExposeCalculateRateAndExecuteRateFields() throws Exception { LoanPricingWorkflowListVO vo = new LoanPricingWorkflowListVO(); vo.setCalculateRate("6.15"); vo.setExecuteRate("5.80"); assertEquals("6.15", vo.getCalculateRate()); assertEquals("5.80", vo.getExecuteRate()); } ``` - [ ] **Step 2: 运行测试确认在对象未创建前失败** Run: `mvn -pl ruoyi-loan-pricing -Dtest=LoanPricingWorkflowListVOTest test` Expected: FAIL，提示 `LoanPricingWorkflowListVO` 不存在或缺少字段。 - [ ] **Step 3: 新增列表专用 VO** 创建 `LoanPricingWorkflowListVO`，至少包含： ```java private String serialNum; private String custName; private String custType; private String guarType; private String applyAmt; private String calculateRate; private String executeRate; private Date createTime; private String createBy; ``` - [ ] **Step 4: 修改 Service 接口与 Controller 返回类型** 将列表分页返回从： ```java IPage ``` 调整为： ```java IPage ``` 并同步更新 Controller 列表接口使用的新分页结果类型。 - [ ] **Step 5: 再次运行测试确认返回对象字段已可用** Run: `mvn -pl ruoyi-loan-pricing -Dtest=LoanPricingWorkflowListVOTest test` Expected: PASS - [ ] **Step 6: 提交这一小步** Run: `git add ruoyi-loan-pricing/src/main/java/com/ruoyi/loanpricing/domain/vo/LoanPricingWorkflowListVO.java ruoyi-loan-pricing/src/main/java/com/ruoyi/loanpricing/service/ILoanPricingWorkflowService.java ruoyi-loan-pricing/src/main/java/com/ruoyi/loanpricing/controller/LoanPricingWorkflowController.java ruoyi-loan-pricing/src/test/java/com/ruoyi/loanpricing/domain/vo/LoanPricingWorkflowListVOTest.java && git commit -m "新增流程列表测算利率返回对象"` Expected: 生成仅包含 VO 与接口调整的中文提交。 ### Task 2: 新增联表 SQL 返回统一测算利率 **Files:** - Modify: `ruoyi-loan-pricing/src/main/java/com/ruoyi/loanpricing/mapper/LoanPricingWorkflowMapper.java` - Create: `ruoyi-loan-pricing/src/main/resources/mapper/loanpricing/LoanPricingWorkflowMapper.xml` - Modify: `ruoyi-loan-pricing/src/main/java/com/ruoyi/loanpricing/service/impl/LoanPricingWorkflowServiceImpl.java` - Test: `ruoyi-loan-pricing/src/test/java/com/ruoyi/loanpricing/service/impl/LoanPricingWorkflowServiceImplTest.java` - [ ] **Step 1: 写一个失败测试，约束服务层返回的列表对象要透传 `calculateRate`** Create/Test: `ruoyi-loan-pricing/src/test/java/com/ruoyi/loanpricing/service/impl/LoanPricingWorkflowServiceImplTest.java` 测试示例： ```java @Test void shouldReturnPagedWorkflowListWithCalculateRate() { Page page = new Page<>(1, 10); LoanPricingWorkflow query = new LoanPricingWorkflow(); LoanPricingWorkflowListVO row = new LoanPricingWorkflowListVO(); row.setCalculateRate("6.15"); when(loanPricingWorkflowMapper.selectWorkflowPageWithRates(any(), any())).thenReturn(new Page().setRecords(List.of(row))); IPage result = service.selectLoanPricingPage(page, query); assertEquals("6.15", result.getRecords().get(0).getCalculateRate()); } ``` - [ ] **Step 2: 运行测试确认在方法未接入前失败** Run: `mvn -pl ruoyi-loan-pricing -Dtest=LoanPricingWorkflowServiceImplTest test` Expected: FAIL，提示方法签名不匹配或 Mapper 自定义方法不存在。 - [ ] **Step 3: 在 Mapper 接口声明列表专用分页方法** 在 `LoanPricingWorkflowMapper` 中新增类似方法： ```java IPage selectWorkflowPageWithRates( Page page, @Param("query") LoanPricingWorkflow query); ``` - [ ] **Step 4: 在 XML 中实现联表 SQL** 创建 `LoanPricingWorkflowMapper.xml`，编写列表专用查询，关键逻辑至少包含： ```xml SELECT lpw.serial_num AS serialNum, lpw.cust_name AS custName, lpw.cust_type AS custType, lpw.guar_type AS guarType, lpw.apply_amt AS applyAmt, CASE WHEN lpw.cust_type = '个人' THEN mr.calculate_rate WHEN lpw.cust_type = '企业' THEN mc.calculate_rate ELSE NULL END AS calculateRate, lpw.execute_rate AS executeRate, lpw.create_time AS createTime, lpw.create_by AS createBy FROM loan_pricing_workflow lpw LEFT JOIN model_retail_output_fields mr ON lpw.model_output_id = mr.id LEFT JOIN model_corp_output_fields mc ON lpw.model_output_id = mc.id ``` 并保留当前筛选条件和按更新时间倒序。 - [ ] **Step 5: 在 ServiceImpl 中改为调用联表分页方法** 将列表分页实现从： ```java return loanPricingWorkflowMapper.selectPage(page, wrapper); ``` 切换为调用新的 Mapper 联表分页方法，保留查询参数透传。 - [ ] **Step 6: 运行服务层测试确认通过** Run: `mvn -pl ruoyi-loan-pricing -Dtest=LoanPricingWorkflowServiceImplTest test` Expected: PASS - [ ] **Step 7: 如需补充 XML 级验证，再运行模块测试** Run: `mvn -pl ruoyi-loan-pricing test` Expected: 至少本次新增测试通过；若存在其他失败，需先区分是否为既有问题。 - [ ] **Step 8: 提交这一小步** Run: `git add ruoyi-loan-pricing/src/main/java/com/ruoyi/loanpricing/mapper/LoanPricingWorkflowMapper.java ruoyi-loan-pricing/src/main/resources/mapper/loanpricing/LoanPricingWorkflowMapper.xml ruoyi-loan-pricing/src/main/java/com/ruoyi/loanpricing/service/impl/LoanPricingWorkflowServiceImpl.java ruoyi-loan-pricing/src/test/java/com/ruoyi/loanpricing/service/impl/LoanPricingWorkflowServiceImplTest.java && git commit -m "新增流程列表测算利率联表查询"` Expected: 生成包含联表 SQL 与服务切换的中文提交。 ### Task 3: 完成后端留档与接口验证 **Files:** - Create: `doc/implementation-report-2026-03-28-workflow-calculate-rate-list-backend.md` - [ ] **Step 1: 补充后端实施记录** 实施记录至少写明： ```markdown - 列表接口返回类型已调整为列表专用 VO - 后端通过联表 SQL 一次返回 `calculateRate` 与 `executeRate` - 个人客户测算利率来自 `model_retail_output_fields.calculate_rate` - 企业客户测算利率来自 `model_corp_output_fields.calculate_rate` ``` - [ ] **Step 2: 验证列表接口返回结构** Run: 按项目现有方式启动后端后，请求 `/loanPricing/workflow/list` Expected: 返回行数据中包含 `calculateRate` 和 `executeRate`。 - [ ] **Step 3: 核对个人和企业记录的测算利率来源** Run: 使用已有测试数据各抽取一条个人和企业记录，对比接口返回与模型输出表数据。 Expected: 个人记录取自零售模型输出表，企业记录取自对公模型输出表。 - [ ] **Step 4: 如果为验证启动了后端进程，结束对应进程** Run: `ps -ef | rg 'RuoYiApplication|java'` Expected: 对本次验证启动的后端进程执行停止；对非本次启动进程不做处理。 - [ ] **Step 5: 提交后端实施记录** Run: `git add doc/implementation-report-2026-03-28-workflow-calculate-rate-list-backend.md && git commit -m "补充测算利率列表后端实施记录"` Expected: 生成仅包含后端留档内容的中文提交。
