# DEF-01 定向整改：`GET /jobs` 公开列表关键词规范化 |
||||
|
|
||||
|
日期：2026-09-20 |
||||
|
分支：`refactor/r01-structure-performance` |
||||
|
基线 HEAD：`2319f97203a2cafcf8012869fda8c30599ffb305`（整改前的 upstream 同点） |
||||
|
方案：**方案 A**（服务入口局部规范化），**不采用方案 B** |
||||
|
本轮性质：定向整改 + 独立复验；未暂存、未提交、未推送 |
||||
|
|
||||
|
--- |
||||
|
|
||||
|
## 1. 修复前最小复现 |
||||
|
|
||||
|
真实 HTTP（整改前，`mvn` 于 `2319f97`）： |
||||
|
|
||||
|
``` |
||||
|
GET /api/v1/jobs?keyword=%20AlphaEngineer%20 → items=0 （期望 1：trim 后应命中） |
||||
|
GET /api/v1/jobs?keyword=%20%20%20 → items=0 （期望 20：空白应等同未传） |
||||
|
GET /api/v1/jobs/ch?keyword=AlphaEngineer → items=1 |
||||
|
GET /api/v1/jobs → items=20 |
||||
|
GET /api/v1/jobs/search?keyword=%20AlphaEngineer%20 → 1 （正确） |
||||
|
GET /api/v1/jobs/search?keyword=%20%20%20 → 20 （正确） |
||||
|
``` |
||||
|
|
||||
|
## 2. 两个端点的调用链 |
||||
|
|
||||
|
| 端点 | 调用链 | 关键词处理 | |
||||
|
|---|---|---| |
||||
|
| `GET /jobs` | `JobController.listJobs:97` → `JobService.listPublishedJobs:123` → `JobRepository.findPublishedJobs`（JPQL） | 只判 `:keyword IS NULL`，**无 trim、无 blank 归一** | |
||||
|
| `GET /jobs/search` | `JobController.searchJobs:134` → `JobService.searchJobs` → `JobSearchSpecification:52-53` | `!keyword.isBlank()` 判空 + `keyword.trim()` | |
||||
|
|
||||
|
## 3. 根因 |
||||
|
|
||||
|
`JobRepository.findPublishedJobs` 的 JPQL 为： |
||||
|
|
||||
|
```sql |
||||
|
AND (:keyword IS NULL OR j.title LIKE %:keyword% OR j.description LIKE %:keyword%) |
||||
|
``` |
||||
|
|
||||
|
- `" AlphaEngineer "` **不是 null** → 生成 `LIKE '% AlphaEngineer %'` → 前导/尾随空格进入匹配串 → **0 条**； |
||||
|
- `" "` **不是 null** → 生成 `LIKE '% %'` → 无意义的过滤条件 → **0 条**； |
||||
|
- `/jobs/search` 已做 `trim()` 与 `isBlank()` 归一 → 两条**公开**查询路径的输入语义不一致。 |
||||
|
|
||||
|
## 4. 为什么选方案 A |
||||
|
|
||||
|
- 缺陷是**输入规范化缺失**，不是查询实现缺陷； |
||||
|
- 方案 A 把规范化放在**唯一入口**（`listPublishedJobs`），一处生效、语义显式、可被单测直接覆盖； |
||||
|
- 改动面最小（1 个文件、+7/−1），**不触碰** Repository / Specification / Controller / DTO / OpenAPI / |
||||
|
排序 / 分页 / 薪资 / 城市 / 状态，回归风险最低。 |
||||
|
|
||||
|
## 5. 为什么不选方案 B |
||||
|
|
||||
|
- 方案 B 让 `/jobs` 改走 `JobSearchSpecification`，会改变 `/jobs` 的**分页 DTO 形态、排序实现与 |
||||
|
查询计划**（`JobSearchItem` 与现有 `toPublicView` 字段并不相同），属于超出缺陷范围的语义扩张； |
||||
|
- 两套实现并存是**既有事实**（`/jobs` 与 `/jobs/search` 本就服务不同调用方）， |
||||
|
合并应作为独立重构批次评估，不应与本次缺陷修复捆绑。 |
||||
|
|
||||
|
## 6. 精确生产修改 |
||||
|
|
||||
|
**唯一文件**：`mydreamjob-server/src/main/java/com/mydreamjob/job/JobService.java` |
||||
|
（`git diff --stat`：**1 file changed, 7 insertions(+), 1 deletion(-)**） |
||||
|
|
||||
|
```java |
||||
|
public Page<Map<String, Object>> listPublishedJobs(String keyword, String city, ...) { |
||||
|
if (salaryMin != null && salaryMax != null && salaryMin > salaryMax) { |
||||
|
throw new BusinessException(ErrorCode.BAD_REQUEST); |
||||
|
} |
||||
|
String normalizedKeyword = keyword == null || keyword.isBlank() ? null : keyword.trim(); // ← 新增 |
||||
|
Pageable pageable = PageRequest.of(page, size, Sort.by(Sort.Direction.DESC, "createdAt")); |
||||
|
Page<Job> result = jobRepository.findPublishedJobs(normalizedKeyword, city, employmentType, // ← 原为 keyword |
||||
|
salaryMin, salaryMax, pageable); |
||||
|
return result.map(this::toPublicView); |
||||
|
} |
||||
|
``` |
||||
|
|
||||
|
（另含一段 Javadoc 说明 DEF-01 的语义契约；不改变任何行为。） |
||||
|
|
||||
|
**未新增通用工具类**：项目内不存在语义完全相同的既有规范化工具，故保持这段局部逻辑。 |
||||
|
|
||||
|
## 7. 输入规范化决策表 |
||||
|
|
||||
|
| 输入 | 规范化结果 | |
||||
|
|---|---| |
||||
|
| `null` | `null` | |
||||
|
| `""` | `null` | |
||||
|
| `" "` | `null` | |
||||
|
| `"AlphaEngineer"` | `"AlphaEngineer"` | |
||||
|
| `" AlphaEngineer "` | `"AlphaEngineer"` | |
||||
|
| `"Alpha Engineer"` | `"Alpha Engineer"`（中间空格**不折叠**） | |
||||
|
|
||||
|
未做：大小写转换、中间空格折叠、SQL 拼接、Repository 改动、Specification 改动、Controller 改动、 |
||||
|
排序/分页/薪资/城市/状态语义改动、公开岗位范围改动。 |
||||
|
|
||||
|
## 8. 新增测试方法名 |
||||
|
|
||||
|
`mydreamjob-server/src/test/java/com/mydreamjob/job/JobListKeywordNormalizationIntegrationTest.java` |
||||
|
（9 项，走**真实链路** HTTP → SecurityFilterChain → JobController → JobService → JobRepository）： |
||||
|
|
||||
|
`plainKeywordFindsPublishedJob`、`trimmedKeywordFindsSamePublishedJob`、`blankKeywordBehavesAsNoKeyword`、 |
||||
|
`emptyKeywordBehavesAsNoKeyword`、`nullOrMissingKeywordListsPublishedJobs`、 |
||||
|
`draftJobNeverAppearsAfterNormalization`、`normalizationDoesNotChangePagination`、 |
||||
|
`normalizationDoesNotChangeExistingSortContract`、`listJobsIsReadOnly` |
||||
|
|
||||
|
夹具：1 条标题含 `AlphaEngineer` 的 PUBLISHED + 2 条其它 PUBLISHED + 1 条 DRAFT + 1 条 CLOSED； |
||||
|
唯一前缀 `DEF01KEYWORD_`；清理**只按显式登记的主键**，不使用 `deleteAll()`；不依赖执行顺序。 |
||||
|
|
||||
|
## 9. 修复前失败结果 |
||||
|
|
||||
|
以**变异验证**给出权威的修复前证据（把 `normalizedKeyword` 改回 `keyword`，其余不动）： |
||||
|
|
||||
|
``` |
||||
|
Tests run: 9, Failures: 4, Errors: 0, Skipped: 0 |
||||
|
JobListKeywordNormalizationIntegrationTest.trimmedKeywordFindsSamePublishedJob FAIL |
||||
|
JobListKeywordNormalizationIntegrationTest.blankKeywordBehavesAsNoKeyword FAIL |
||||
|
JobListKeywordNormalizationIntegrationTest.normalizationDoesNotChangePagination FAIL |
||||
|
JobListKeywordNormalizationIntegrationTest.normalizationDoesNotChangeExistingSortContract FAIL |
||||
|
``` |
||||
|
|
||||
|
即 **trim 与 blank 两类断言在缺失修复时必然失败**（≥2 项，满足要求）。 |
||||
|
|
||||
|
## 10. 修复后结果 |
||||
|
|
||||
|
| 命令 | 结果 | |
||||
|
|---|---| |
||||
|
| `mvn -Dtest="JobListKeywordNormalizationIntegrationTest" test` | **9 / 0 / 0 / 0** | |
||||
|
| `mvn -Dtest="*Job*Test,*JobSearch*Test" test` | **219 / 0 / 0 / 0** | |
||||
|
|
||||
|
## 11. 真实 MySQL HTTP 结果 |
||||
|
|
||||
|
最新 JAR（`mvn clean verify` 产物）+ 真实 MySQL/Redis/RabbitMQ，前缀 `DEF01_20260920_`： |
||||
|
**11 / 11 通过**。 |
||||
|
|
||||
|
| 断言 | 实测 | |
||||
|
|---|---| |
||||
|
| 普通关键词 HTTP 200 且只命中目标 | `200, [target]` ✔ | |
||||
|
| 两侧空白与普通关键词：ID/顺序/数量一致 | `pad=[T] plain=[T]` ✔ | |
||||
|
| 纯空白与无关键词：ID/顺序/总数一致 | `blank == none` ✔ | |
||||
|
| 空字符串与无关键词：一致 | `empty == none` ✔ | |
||||
|
| DRAFT 不进入公开结果 | `statuses=['PUBLISHED']` ✔ | |
||||
|
| 分页 metadata 不因规范化变化 | `total=1,page=0,size=1,totalPages=1` ✔ | |
||||
|
| 默认排序不变（夹具 createdAt 降序） | `none == blank`，desc ✔ | |
||||
|
| 不返回 4xx/5xx | `[200]×7` ✔ | |
||||
|
| 响应不泄露 SQL/异常/路径/堆栈 | `leaks=[]` ✔ | |
||||
|
| 对照 `/jobs/search` 的 trim/blank 语义一致 | `pad==plain`、`blank==全部` ✔ | |
||||
|
| 请求前后数据库逐字段零变化 | `changed=none` ✔ | |
||||
|
|
||||
|
## 12. 变异测试结果 |
||||
|
|
||||
|
- 保存 `JobService.java` **原始字节**（sha256 前 16 位 `b4fab0034b34d569`，14 699 字节）； |
||||
|
- 变异：`findPublishedJobs(normalizedKeyword, …)` → `findPublishedJobs(keyword, …)`； |
||||
|
- 结果：**4 项失败**（见 §9）； |
||||
|
- **按原始字节精确恢复**（**未使用** `git restore` / `git checkout`），恢复后 sha 一致； |
||||
|
- 复跑新增测试 **9/9 绿**；校验无变异残留（`findPublishedJobs(keyword,` 计数 = 0， |
||||
|
`String normalizedKeyword =` 计数 = 1）。 |
||||
|
|
||||
|
## 13. 岗位关联回归 |
||||
|
|
||||
|
`mvn -Dtest="*Job*Test,*JobSearch*Test" test` → **219 / 0 / 0 / 0**（未修改或删除任何既有断言）。 |
||||
|
|
||||
|
## 14. 全量测试数 |
||||
|
|
||||
|
| 命令 | Tests | Failures | Errors | Skipped | BUILD | |
||||
|
|---|---|---|---|---|---| |
||||
|
| `mvn test` | **2797** | 0 | 0 | 0 | SUCCESS | |
||||
|
| `mvn clean verify` | **2797** | 0 | 0 | 0 | SUCCESS | |
||||
|
|
||||
|
`2797 = 2788（基线）+ 9（本轮新增）`，满足「不低于 2788 + 新增数」。 |
||||
|
Testcontainers MySQL 用例实际执行（`Skipped=0`）。 |
||||
|
|
||||
|
## 15. OpenAPI |
||||
|
|
||||
|
``` |
||||
|
python ..\docs\verify_openapi.py → paths: 176 / operations: 214 / All checks passed! |
||||
|
``` |
||||
|
|
||||
|
`docs/openapi-rc.json` **未修改**（`git diff` 为空）。 |
||||
|
|
||||
|
## 16. 数据副作用 |
||||
|
|
||||
|
- 黑盒前后 7 张表（jobs / companies / users / user_roles / audit_logs / notifications / applications） |
||||
|
**逐字段零变化**； |
||||
|
- 单测 `listJobsIsReadOnly` 对 5 张表逐字段零变化； |
||||
|
- 夹具残留 **0**；历史未跟踪文件与历史数据（含 `users.id` 7938/7939 的 `user_roles`）完好； |
||||
|
- `audit_logs` **未删除任何行**。 |
||||
|
|
||||
|
## 17. 精确修改文件 |
||||
|
|
||||
|
``` |
||||
|
M mydreamjob-server/src/main/java/com/mydreamjob/job/JobService.java （+7 −1） |
||||
|
?? mydreamjob-server/src/test/java/com/mydreamjob/job/JobListKeywordNormalizationIntegrationTest.java （新增，9 项） |
||||
|
?? docs/def-01-job-keyword-normalization-remediation-20260920.md （本报告） |
||||
|
?? docs/final-independent-acceptance-20260918.md （追加 DEF-01 章节） |
||||
|
``` |
||||
|
|
||||
|
## 18. Git 状态（整改与复验阶段） |
||||
|
|
||||
|
| 项 | 结果 | |
||||
|
|---|---| |
||||
|
| 生产代码改动 | **仅 `JobService.java` 1 个文件** | |
||||
|
| `JobRepository` / `JobSearchSpecification` / `JobController` | **零修改** | |
||||
|
| 其他生产模块 / Flyway / `pom.xml` / `openapi-rc.json` | **零修改** | |
||||
|
| 验收脚本与原始产物 | **零修改** | |
||||
|
|
||||
|
## 19. 未涉及范围 |
||||
|
|
||||
|
未进入：简历隐私矩阵、管理员初始化矩阵、Q01 H2/MySQL 对账与 EXPLAIN 分表、写侧刷新链路 |
||||
|
（四项 SKIP 仍待验收）。 |
||||
|
|
||||
|
## 20. 本轮测试自身缺陷（非产品缺陷，已修正并记录） |
||||
|
|
||||
|
| # | 现象 | 判定 | 修正 | |
||||
|
|---|---|---|---| |
||||
|
| T-1 | 「带空白关键词」用例恒返回空 | **测试缺陷**：MockMvc 对 URL 模板二次编码（`%20` → `%2520`），测的是字面量 `%20` 而非空白参数 | 改用 `.param()` 传参 | |
||||
|
| T-2 | 分页/排序断言随更大范围运行而失败 | **测试缺陷**：断言了既有契约**不保证**的顺序 —— 默认排序 `createdAt DESC` 无 tiebreaker，并列时入选子集与顺序均不稳定 | 夹具改用**显式互异 `created_at`**；分页用例只断言确定性元数据 | |
||||
|
| T-3 | 黑盒夹具未创建 | **脚本缺陷**：`seed_sms_codes/login` 使用 `lib.phone()`（`199000` 号段），而建公司语句另写了 `199002` 号段，两者是**不同号码**，公司被挂到不存在的用户上（号码为本地验收自建夹具，报告中脱敏） | 统一为 `lib.phone(CO)` | |
||||
|
| T-4 | 黑盒「默认排序」断言失败 | **脚本缺陷**：把「关键词过滤后的结果」与「无关键词的完整结果」做相等比较，语义不同 | 只比较同为未过滤的 `none` 与 `blank` | |
||||
|
|
||||
|
## 21. 明确声明 |
||||
|
|
||||
|
**未修改** `/jobs/search`、`JobSearchSpecification`、`JobRepository` JPQL、Controller 路由、 |
||||
|
排序/分页/薪资/城市/状态过滤、DTO、OpenAPI、`ErrorCode`、`SecurityConfig`、V1–V45、`pom.xml`； |
||||
|
**未新增 V46**；**未修改任何既有测试断言**；**未**执行 `git reset/restore/checkout/clean`； |
||||
|
**未**使用 `git add -A` / `git add .` / 目录级暂存；**未**删除或移动历史未跟踪文件。 |
||||
|
|
||||
|
本报告与 `docs/final-independent-acceptance-20260918.md` 的 DEF-01 追加章节于提交前保持**待提交**状态。 |
