补充测算利率列表前后端实施计划
2026-03-28 11:58:34 +08:00
# 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<LoanPricingWorkflow>
```
调整为：
```java
IPage<LoanPricingWorkflowListVO>
```
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<LoanPricingWorkflowListVO> 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<LoanPricingWorkflowListVO>().setRecords(List.of(row)));
IPage<LoanPricingWorkflowListVO> 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<LoanPricingWorkflowListVO> selectWorkflowPageWithRates(
Page<LoanPricingWorkflowListVO> 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。
