# V39：测评结果驱动岗位推荐设计 |
||||
|
|
||||
|
> 状态：**编码完成，真实 MySQL/Docker 关键黑盒已通过，待 Git 检查点。** |
||||
|
> 功能版本：V39。 |
||||
|
> 当前基线：Flyway 迁移新增 `V37__job_recommendation_profiles.sql`；静态 OpenAPI 为 `154 paths / 190 operations`。 |
||||
|
> 文档用途：V39 第一版规则、接口、安全边界与验收口径的权威设计说明。 |
||||
|
|
||||
|
## 1. 目标与边界 |
||||
|
|
||||
|
### 1.1 目标 |
||||
|
|
||||
|
为学生提供“可解释、可复现、可关闭”的岗位推荐列表。推荐只使用学生已授权产生的偏好、V35 RIASEC 职业兴趣结果和 V36 四维能力结果，并结合企业为岗位维护的结构化推荐画像。 |
||||
|
|
||||
|
推荐的含义是“当前岗位与学生已知偏好的匹配程度”，不保证录用概率，不构成职业、心理或就业诊断。 |
||||
|
|
||||
|
### 1.2 第一版范围 |
||||
|
|
||||
|
- 仅 STUDENT 查看自己的推荐岗位。 |
||||
|
- 仅推荐状态为 `PUBLISHED` 且学生尚未投递的岗位。 |
||||
|
- 使用学生偏好、最新完成的 RIASEC 结果、最新有效的四维能力结果和岗位推荐画像。 |
||||
|
- 企业只能维护自己岗位的推荐画像；不能查询任何学生的测评明细、推荐分或推荐理由。 |
||||
|
- 返回有限、白名单化的推荐理由和缺口提示。 |
||||
|
- 规则实时计算；不保存学生级推荐历史、点击画像或行为画像。 |
||||
|
|
||||
|
### 1.3 明确不在本版范围 |
||||
|
|
||||
|
- 不使用 AI、大模型、简历文本向量或隐式行为画像。 |
||||
|
- 不自动投递、不替学生收藏、不发送推荐通知。 |
||||
|
- 不增加企业人才推荐或企业查看学生测评详情。 |
||||
|
- 不接入 V38 之外的 `GROWTH` 评分维度，不写 `candidate_dimension_scores`。 |
||||
|
- 不把 RIASEC 结果当作职业诊断，不根据测评结果拒绝学生投递。 |
||||
|
- 实现“我不感兴趣”持久化，以及推荐解释的有帮助/无帮助反馈；首版不将反馈用于模型训练。 |
||||
|
|
||||
|
## 2. 现状核查结论 |
||||
|
|
||||
|
| 已有能力 | 当前状态 | 对 V39 的影响 | |
||||
|
|---|---|---| |
||||
|
| 岗位搜索 | `/jobs` 已支持城市、薪资、用工类型、关键词和分页 | 可复用公开岗位视图和发布状态口径 | |
||||
|
| 单岗位匹配诊断 | `GET /jobs/{jobId}/match`，按学生偏好计算 | 只适合单岗位说明；内部会写审计，不应在推荐列表中逐岗位循环调用 | |
||||
|
| 学生偏好 | 城市、薪资、用工类型、行业、岗位类型、远程意愿 | 可作为硬过滤和软匹配数据 | |
||||
|
| V35 RIASEC | 最新完成结果可提供六维兴趣聚合分 | 可作为兴趣匹配输入；不读取答案和题目 | |
||||
|
| V36 四维能力 | 最新有效完成结果可提供四维聚合分和有效期 | 可作为能力适配输入；不依赖 V38 开关 | |
||||
|
| V38 评分接入 | ABILITY 可有限进入候选评分 | V39 直接读 V36 聚合结果，不读取候选评分快照，避免推荐随评分开关改变 | |
||||
|
| `jobs` 表 | 只有标题、描述、要求、城市、薪资、用工类型 | 缺少可靠的 RIASEC/能力要求字段，必须新增结构化岗位推荐画像 | |
||||
|
|
||||
|
## 3. 总体方案 |
||||
|
|
||||
|
### 3.1 方案选择 |
||||
|
|
||||
|
采用“**规则推荐 + 岗位结构化画像 + 实时只读计算**”方案。 |
||||
|
|
||||
|
```text |
||||
|
学生偏好 ─────────────┐ |
||||
|
V35 RIASEC 聚合结果 ──┼─> RecommendationService ─> 推荐岗位列表 + 理由/缺口 |
||||
|
V36 能力聚合结果 ─────┤ ↑ |
||||
|
岗位推荐画像 ─────────┘ └─ 仅查询 PUBLISHED、未投递岗位 |
||||
|
``` |
||||
|
|
||||
|
不能使用岗位标题、岗位描述或 `requirements` 进行关键词猜测来代替岗位画像：该做法不可解释、难以测试，也会把同义词、否定语句和描述质量差异误当成职业要求。 |
||||
|
|
||||
|
### 3.2 推荐画像的维护主体 |
||||
|
|
||||
|
企业在创建或维护岗位后，为本人岗位维护一份结构化推荐画像。画像只描述岗位，不包含学生数据；它包含： |
||||
|
|
||||
|
- 行业代码与岗位族代码，用于与学生偏好精确比较； |
||||
|
- RIASEC 六维权重，用于表达该岗位偏好的兴趣侧重点； |
||||
|
- 四维能力期望值，用于表达完成该岗位所需的基础能力水平； |
||||
|
- 是否启用测评推荐。 |
||||
|
|
||||
|
企业画像是“岗位推荐参考”，不是招聘门槛。企业仍需通过原有岗位说明、投递、面试与 Offer 流程进行评估。 |
||||
|
|
||||
|
### 3.3 平台受控分类与审核流 |
||||
|
|
||||
|
行业代码和岗位族代码采用“**平台维护、企业选择、不得自由输入**”的两级受控字典： |
||||
|
|
||||
|
```text |
||||
|
行业大类（industry） |
||||
|
└─ 岗位族（job family） |
||||
|
└─ 企业保留自由填写的岗位标题（jobs.title） |
||||
|
``` |
||||
|
|
||||
|
该选择参考了主流招聘产品按大类、细分职类组织职位浏览和筛选的做法：分类用于匹配与检索，岗位标题保留企业对具体职位的表达。第一版字典由产品负责人确定编码、后端随 Flyway 种子发布；ADMIN 只审核企业的岗位画像，不可在线任意新增分类。分类变更必须通过代码评审、版本化种子和兼容迁移完成。 |
||||
|
|
||||
|
建议首批受控岗位族覆盖当前产品最常见的求职方向：互联网技术、产品、设计、运营/市场、销售/客户成功、人力/行政/财务/法务、生产制造/工程、教育/医疗、供应链/物流、零售/生活服务和综合管理。每个岗位族必须隶属唯一行业大类，编码一经发布不得重用。 |
||||
|
|
||||
|
企业首次保存或修改已审核画像后，画像进入 `PENDING_REVIEW`；只有 `APPROVED` 且 `enabled=true` 的画像可用于个性化推荐。ADMIN 使用固定理由码审批或驳回。企业主动停用画像可立即生效，不需要等待审核。 |
||||
|
|
||||
|
### 3.4 时间一致性 |
||||
|
|
||||
|
一次推荐请求在服务入口生成唯一的 `capturedNow`，V36 结果有效性、规则版本和返回时间均使用该时间点。不得在同一请求内多次调用 `now()` 导致结果边界不一致。 |
||||
|
|
||||
|
## 4. 数据来源与有效性 |
||||
|
|
||||
|
| 来源 | 选择规则 | 无数据/异常处理 | 禁止读取 | |
||||
|
|---|---|---|---| |
||||
|
| 学生偏好 | 本人 `student_preferences`，至多一条 | 缺字段时该偏好项不计入分母 | 其他学生偏好 | |
||||
|
| RIASEC | `HOLLAND_RIASEC` 类型、`COMPLETED`、按完成时间倒序和答卷 ID 倒序取一条 | JSON 损坏、缺维、分数越界时兴趣信号不可用 | 原始答案、题目、questionCode | |
||||
|
| 四维能力 | `WORKPLACE_ABILITY`、`COMPLETED`、`valid_until > capturedNow`、按完成时间倒序和答卷 ID 倒序取一条 | 过期、缺维、不是 24/24 完成时能力信号不可用 | 原始答案、题目反馈、答案键、评分规则 | |
||||
|
| 岗位画像 | `job_recommendation_profiles.enabled=true`、`review_status=APPROVED` 且关联 `PUBLISHED` 岗位 | 无画像或待审核画像不宣称“测评匹配”；仅进入兜底列表 | 企业内部非公开数据 | |
||||
|
| 投递记录 | 当前学生与岗位的任何已有投递记录 | 已投递岗位从推荐候选中排除 | 其他学生投递数据 | |
||||
|
| 推荐反馈 | 本人对岗位的有效 `NOT_INTERESTED` 反馈 | 仅排除本人明确不感兴趣的岗位；理由反馈不改变排序 | 其他学生反馈 | |
||||
|
|
||||
|
RIASEC 只使用六维聚合百分比；四维能力只使用 LOGIC、COMMUNICATION、EXECUTION、LEARNING 四个聚合分。两类结果均须通过服务端结构校验后才可参与排序。 |
||||
|
|
||||
|
## 5. 推荐候选、过滤与排序 |
||||
|
|
||||
|
### 5.1 硬过滤 |
||||
|
|
||||
|
推荐候选必须同时满足： |
||||
|
|
||||
|
1. 岗位状态为 `PUBLISHED`； |
||||
|
2. 当前学生不存在该岗位的任何投递记录，避免推荐一个无法再次投递的岗位； |
||||
|
3. 若学生已设置期望城市，岗位城市必须命中； |
||||
|
4. 若学生已设置期望薪资下限且岗位有薪资上限，学生下限不得高于岗位上限； |
||||
|
5. 当前学生没有对该岗位提交有效的 `NOT_INTERESTED` 反馈； |
||||
|
6. 岗位推荐画像存在、已启用且审核状态为 `APPROVED` 时，才进入“个性化推荐”排序。 |
||||
|
|
||||
|
城市和薪资口径与现有单岗位匹配诊断保持一致。用工类型、行业和岗位族是软信号，不作为拒绝或隐藏条件。 |
||||
|
|
||||
|
### 5.2 三类软信号 |
||||
|
|
||||
|
| 信号 | 默认权重 | 计算方式 | |
||||
|
|---|---:|---| |
||||
|
| 偏好适配 `P` | 40% | 城市 30、用工类型 20、薪资 20、行业 15、岗位族 15；只对学生已设置且岗位有对应结构化值的字段纳入分母 | |
||||
|
| 兴趣适配 `I` | 35% | `Σ(RIASEC学生维度分 × 岗位该维权重) / Σ岗位兴趣权重` | |
||||
|
| 能力适配 `A` | 25% | 对每个已配置能力期望值：学生分数大于等于期望值记 100，否则 `学生分 / 期望分 × 100`；再取已配置维度平均值 | |
||||
|
|
||||
|
总分公式： |
||||
|
|
||||
|
```text |
||||
|
recommendationScore = |
||||
|
(P × 40 + I × 35 + A × 25) / 可用信号权重之和 |
||||
|
``` |
||||
|
|
||||
|
结果保留两位小数，使用 `HALF_UP`。缺失或无效信号不记为 0，而是从分母中移除；这样不会因为学生尚未完成某项测评而被无理由降分。 |
||||
|
|
||||
|
如果偏好、兴趣、能力三者都不可用，则该岗位不能标为个性化推荐。 |
||||
|
|
||||
|
### 5.3 排序与兜底 |
||||
|
|
||||
|
个性化岗位按以下顺序排序： |
||||
|
|
||||
|
1. `recommendationScore DESC`； |
||||
|
2. `published_at DESC`； |
||||
|
3. `job_id DESC`。 |
||||
|
|
||||
|
若没有任何可用个性化结果，接口返回 `mode=FALLBACK` 的公开岗位兜底列表，只按发布时间排序，`recommendationScore=null`，并明确说明“完善偏好或完成测评后可获得个性化推荐”。兜底列表绝不伪装为个性化结果。 |
||||
|
|
||||
|
### 5.4 理由与缺口 |
||||
|
|
||||
|
每个个性化岗位最多返回 3 条理由和 2 条建议，均由固定白名单模板生成，例如： |
||||
|
|
||||
|
- `PREFERENCE_CITY_MATCH`：工作城市符合你的偏好； |
||||
|
- `PREFERENCE_SALARY_MATCH`：薪资范围满足你的期望； |
||||
|
- `RIASEC_INTEREST_MATCH`：职业兴趣与岗位侧重点较匹配； |
||||
|
- `ABILITY_STRENGTH_MATCH`：你的能力表现满足该岗位的主要侧重点； |
||||
|
- `ABILITY_GAP`：可优先提升与岗位相关的某项能力； |
||||
|
- `PREFERENCE_GAP`：用工类型或岗位族与当前偏好存在差异。 |
||||
|
|
||||
|
不返回 RIASEC 原始六维向量、能力答卷 ID、结果 ID、题目、答案、答案键、评分规则或企业配置原文。 |
||||
|
|
||||
|
## 6. 数据模型与 Flyway（建议，待确认） |
||||
|
|
||||
|
### 6.1 迁移 |
||||
|
|
||||
|
当前最新迁移为 V36；建议新增： |
||||
|
|
||||
|
```text |
||||
|
V37__job_recommendation_profiles.sql |
||||
|
``` |
||||
|
|
||||
|
功能版本仍为 V39。该单一迁移创建岗位画像、受控分类和学生反馈三张相关表，不修改 V1–V36 的语义。 |
||||
|
|
||||
|
### 6.2 `job_recommendation_taxonomies` |
||||
|
|
||||
|
平台受控字典表，随 `job-taxonomy-v0.1` 种子初始化。 |
||||
|
|
||||
|
| 字段 | 说明 | |
||||
|
|---|---| |
||||
|
| `code` | 不可重用的稳定编码，主键 | |
||||
|
| `parent_code` | 岗位族指向所属行业大类；行业大类为 `NULL` | |
||||
|
| `taxonomy_type` | `INDUSTRY` 或 `JOB_FAMILY` | |
||||
|
| `display_name` | 前端展示名 | |
||||
|
| `active` | 是否仍允许企业新选用 | |
||||
|
| `sort_order`、`catalog_version` | 展示顺序与目录版本 | |
||||
|
|
||||
|
服务端必须校验 `industry_code` 是有效行业大类、`job_family_code` 是该行业下有效岗位族；企业不得传任意文本或跨层级组合。 |
||||
|
|
||||
|
### 6.3 `job_recommendation_profiles` |
||||
|
|
||||
|
| 字段 | 说明 | |
||||
|
|---|---| |
||||
|
| `id` | 主键 | |
||||
|
| `job_id` | 外键至 `jobs.id`，唯一，一岗一份画像 | |
||||
|
| `enabled` | 是否参与个性化推荐，默认 `false` | |
||||
|
| `review_status` | `PENDING_REVIEW`、`APPROVED`、`REJECTED`、`DISABLED` | |
||||
|
| `industry_code` | 必填、受控行业大类编码 | |
||||
|
| `job_family_code` | 必填、受控岗位族编码 | |
||||
|
| `riasec_r` 至 `riasec_c` | 六维兴趣权重，`0..100`，至少一个非零才可启用兴趣信号 | |
||||
|
| `logic_requirement` 等四列 | 四维能力期望值，`0..100`；`NULL` 表示该维不参与能力适配 | |
||||
|
| `reviewed_by_user_id`、`reviewed_at` | 最近一次审核人和审核时间，仅内部使用 | |
||||
|
| `review_reason_code` | 审核/驳回的固定理由码，不存自由文本 | |
||||
|
| `profile_version` | 乐观锁版本 | |
||||
|
| `created_at`、`updated_at` | 审计时间 | |
||||
|
|
||||
|
约束与索引： |
||||
|
|
||||
|
- `UNIQUE(job_id)`； |
||||
|
- `FOREIGN KEY(job_id) REFERENCES jobs(id)`； |
||||
|
- 所有权重和能力期望必须在 `0..100`； |
||||
|
- 建立 `(enabled, review_status, job_id)` 索引，支撑可推荐画像的候选岗位查询； |
||||
|
- 使用 JPA `@Version` 和 `expectedVersion` 防止企业并发覆盖配置。 |
||||
|
|
||||
|
### 6.4 `student_job_recommendation_feedback` |
||||
|
|
||||
|
仅保存学生主动提交的最小化反馈，不保存自动点击画像。 |
||||
|
|
||||
|
| 字段 | 说明 | |
||||
|
|---|---| |
||||
|
| `id` | 主键 | |
||||
|
| `student_user_id`、`job_id` | 反馈所属学生和岗位 | |
||||
|
| `feedback_type` | `NOT_INTERESTED`、`REASON_HELPFUL`、`REASON_NOT_HELPFUL` | |
||||
|
| `reason_code` | 可选固定理由码；不得提交自由文本、测评内容或个人信息 | |
||||
|
| `feedback_key` | `student + job + type + reasonCode` 组成的非空去重键 | |
||||
|
| `status` | `ACTIVE` 或 `REVOKED`；撤销不物理删除 | |
||||
|
| `idempotency_key` | 同一学生请求幂等键唯一；同键异体返回冲突 | |
||||
|
| `created_at`、`updated_at`、`version` | 审计时间与乐观锁 | |
||||
|
|
||||
|
`NOT_INTERESTED` 有效时排除该岗位；理由是否“有帮助”只用于后续人工优化规则，不自动改变学生分、岗位分或排序公式。 |
||||
|
|
||||
|
## 7. API 设计（建议，待确认） |
||||
|
|
||||
|
### 7.1 学生推荐列表 |
||||
|
|
||||
|
```http |
||||
|
GET /profile/me/job-recommendations?page=0&size=20 |
||||
|
``` |
||||
|
|
||||
|
权限：仅 STUDENT 本人。`page` 从 0 开始，`size` 范围 1–50。 |
||||
|
|
||||
|
响应核心字段： |
||||
|
|
||||
|
```json |
||||
|
{ |
||||
|
"mode": "PERSONALIZED", |
||||
|
"rulesVersion": "job-recommendation-v0.1", |
||||
|
"items": [ |
||||
|
{ |
||||
|
"job": { "id": 101, "title": "后端开发工程师", "city": "合肥" }, |
||||
|
"recommendationScore": 82.50, |
||||
|
"reasons": ["PREFERENCE_CITY_MATCH", "RIASEC_INTEREST_MATCH"], |
||||
|
"suggestions": ["ABILITY_GAP"], |
||||
|
"availableSignals": ["PREFERENCE", "RIASEC", "ABILITY"] |
||||
|
} |
||||
|
], |
||||
|
"page": 0, |
||||
|
"size": 20, |
||||
|
"total": 1, |
||||
|
"totalPages": 1, |
||||
|
"generatedAt": "2026-09-04T12:00:00" |
||||
|
} |
||||
|
``` |
||||
|
|
||||
|
岗位详情继续复用既有 `GET /jobs/{jobId}`；如需查看单个岗位的偏好诊断，继续复用既有 `GET /jobs/{jobId}/match`。 |
||||
|
|
||||
|
### 7.2 企业岗位画像查询与更新 |
||||
|
|
||||
|
```http |
||||
|
GET /companies/me/jobs/{jobId}/recommendation-profile |
||||
|
PUT /companies/me/jobs/{jobId}/recommendation-profile |
||||
|
``` |
||||
|
|
||||
|
仅岗位所属 COMPANY 可查询和更新。更新请求需带 `expectedVersion`，并仅接受固定字段：`enabled`、`industryCode`、`jobFamilyCode`、`riasecWeights`、`abilityRequirements`。新建/更新后进入 `PENDING_REVIEW`；只有企业主动 `enabled=false` 时可转为 `DISABLED`。 |
||||
|
|
||||
|
不提供 DELETE；企业通过 `enabled=false` 停用画像，保留配置和审计链路。 |
||||
|
|
||||
|
### 7.3 受控分类、学生反馈与 ADMIN 审核 |
||||
|
|
||||
|
```http |
||||
|
GET /job-recommendation-taxonomies |
||||
|
POST /profile/me/job-recommendations/{jobId}/feedback |
||||
|
DELETE /profile/me/job-recommendations/{jobId}/feedback |
||||
|
GET /admin/job-recommendation-profiles?page=0&size=20&status=PENDING_REVIEW |
||||
|
POST /admin/job-recommendation-profiles/{jobId}/decision |
||||
|
``` |
||||
|
|
||||
|
分类接口只返回 `code`、`parentCode`、`type`、`displayName`、`sortOrder` 和 `catalogVersion`；无需登录即可让岗位发布和岗位搜索复用同一字典。 |
||||
|
|
||||
|
反馈创建必须携带 `idempotencyKey`。`NOT_INTERESTED` 的撤销只把对应记录改为 `REVOKED`；不删除审计记录。ADMIN 审核请求只接受 `APPROVE` 或 `REJECT` 与固定 `reasonCode`，不接受自由文本。 |
||||
|
|
||||
|
### 7.4 OpenAPI 预估 |
||||
|
|
||||
|
新增 6 个路径、8 个 operation： |
||||
|
|
||||
|
```text |
||||
|
148 paths / 182 operations → 154 paths / 190 operations |
||||
|
``` |
||||
|
|
||||
|
编码时必须以运行时 OpenAPI 为准更新 `docs/openapi-rc.json` 与 `docs/verify_openapi.py`，不允许仅修改静态计数。 |
||||
|
|
||||
|
## 8. 权限、隐私与审计 |
||||
|
|
||||
|
| 操作 | STUDENT | COMPANY | ADMIN | 未登录 | |
||||
|
|---|---:|---:|---:|---:| |
||||
|
| 查看本人推荐列表 | 200 | 403/2002 | 403/2002 | 401 | |
||||
|
| 提交/撤销本人推荐反馈 | 200 | 403/2002 | 403/2002 | 401 | |
||||
|
| 查看本人岗位匹配诊断 | 既有行为 | 既有行为 | 既有行为 | 既有行为 | |
||||
|
| 查看自己岗位画像 | 403/2002 | 仅所属岗位 200 | 403/2002 | 401 | |
||||
|
| 更新自己岗位画像 | 403/2002 | 仅所属岗位 200，进入待审核 | 403/2002 | 401 | |
||||
|
| 查询受控分类 | 200 | 200 | 200 | 200 | |
||||
|
| 查看待审核岗位画像 | 403/2002 | 403/2002 | 200 | 401 | |
||||
|
| 审批岗位画像 | 403/2002 | 403/2002 | 200 | 401 | |
||||
|
|
||||
|
审计动作建议： |
||||
|
|
||||
|
- `JOB_RECOMMENDATION_PROFILE_UPDATED`：仅记录 `jobId`、画像版本、是否启用、请求 ID 和时间； |
||||
|
- `JOB_RECOMMENDATION_PROFILE_DECIDED`：仅记录 `jobId`、决定、固定理由码、画像版本、请求 ID 和时间； |
||||
|
- `JOB_RECOMMENDATION_FEEDBACK_CREATED` / `JOB_RECOMMENDATION_FEEDBACK_REVOKED`：仅记录 `jobId`、反馈类型、固定理由码、请求 ID 和时间； |
||||
|
- `JOB_RECOMMENDATIONS_VIEWED`：可选，仅记录返回数量、规则版本和请求 ID；不得记录完整排序、测评分、题目、答案、手机、邮箱、IP、User-Agent 或 token。 |
||||
|
|
||||
|
公司端绝不获得学生的 RIASEC、四维能力、候选评分、推荐分、推荐理由或缺口。学生端也不获得企业配置的完整权重和能力期望值。 |
||||
|
|
||||
|
## 9. 模块边界、性能与并发 |
||||
|
|
||||
|
### 9.1 建议模块划分 |
||||
|
|
||||
|
- `JobRecommendationProfile` / Repository：岗位画像配置； |
||||
|
- `JobRecommendationTaxonomy` / Repository：平台受控行业与岗位族字典； |
||||
|
- `StudentJobRecommendationFeedback` / Repository：学生显式反馈及撤销状态； |
||||
|
- `JobRecommendationProfileService`：企业画像读取、所有权校验和乐观锁更新； |
||||
|
- `JobRecommendationAdminService`：待审核画像分页和固定决定流转； |
||||
|
- `StudentRecommendationSource`：一次读取学生偏好、最新有效 V35/V36 聚合结果； |
||||
|
- `JobRecommendationCalculator`：纯函数，执行结构校验、分数公式和理由模板； |
||||
|
- `JobRecommendationService`：过滤、分页、排序和响应白名单； |
||||
|
- `JobRecommendationController`：仅从 `SecurityContext` 获取当前用户 ID。 |
||||
|
|
||||
|
### 9.2 N+1 防护 |
||||
|
|
||||
|
推荐列表不得对每个岗位调用现有 `MatchService.diagnose()`：该方法会逐岗位读数据并写审计，既会造成 N+1，也会污染审计。 |
||||
|
|
||||
|
推荐请求的目标查询上限为固定次数： |
||||
|
|
||||
|
1. 学生偏好一次； |
||||
|
2. 最新 RIASEC 结果一次； |
||||
|
3. 最新有效四维能力结果一次； |
||||
|
4. 分页候选岗位及画像一次； |
||||
|
5. 当前学生已投递岗位 ID 集合一次； |
||||
|
6. 当前学生有效 `NOT_INTERESTED` 岗位 ID 集合一次； |
||||
|
7. 页面企业信息批量加载一次。 |
||||
|
|
||||
|
岗位排序应使用单条参数化 SQL/JPA 查询按推荐表达式完成，或在有明确候选上限时使用固定批量加载；禁止“每岗位再查画像、公司、投递或测评”的循环查询。编码后必须用 Hibernate/JDBC Spy 断言查询次数不随页面 items 数线性增加。 |
||||
|
|
||||
|
### 9.3 并发 |
||||
|
|
||||
|
- 推荐查询只读、无幂等键要求； |
||||
|
- 企业更新画像、学生反馈撤销和 ADMIN 审核均使用 `expectedVersion` + `@Version`，冲突返回 409； |
||||
|
- 岗位关闭、画像停用或学生完成投递后，下一次查询自然不再返回该岗位；不缓存旧结果。 |
||||
|
|
||||
|
## 10. 错误码（建议） |
||||
|
|
||||
|
建议使用新段 `10001–10009`： |
||||
|
|
||||
|
| 错误码 | HTTP | 含义 | |
||||
|
|---|---:|---| |
||||
|
| `10001` | 404 | `JOB_RECOMMENDATION_PROFILE_NOT_FOUND` | |
||||
|
| `10002` | 400 | `JOB_RECOMMENDATION_PROFILE_INVALID` | |
||||
|
| `10003` | 409 | `JOB_RECOMMENDATION_PROFILE_CONCURRENT_UPDATE` | |
||||
|
| `10004` | 400 | `JOB_RECOMMENDATION_INVALID_QUERY` | |
||||
|
| `10005` | 400 | `JOB_RECOMMENDATION_TAXONOMY_INVALID` | |
||||
|
| `10006` | 409 | `JOB_RECOMMENDATION_FEEDBACK_CONCURRENT_UPDATE` | |
||||
|
| `10007` | 409 | `JOB_RECOMMENDATION_FEEDBACK_IDEMPOTENCY_CONFLICT` | |
||||
|
| `10008` | 404 | `JOB_RECOMMENDATION_FEEDBACK_NOT_FOUND` | |
||||
|
| `10009` | 409 | `JOB_RECOMMENDATION_PROFILE_INVALID_REVIEW_STATE` | |
||||
|
|
||||
|
现有岗位不存在、岗位归属不匹配、未登录和角色越权继续使用既有错误码，不重复造码。 |
||||
|
|
||||
|
## 11. 功能开关、兼容与回滚 |
||||
|
|
||||
|
建议新增默认关闭的开关： |
||||
|
|
||||
|
```yaml |
||||
|
recommendation: |
||||
|
assessment: |
||||
|
enabled: ${RECOMMENDATION_ASSESSMENT_ENABLED:false} |
||||
|
``` |
||||
|
|
||||
|
开关关闭时，学生推荐接口只返回 `FALLBACK` 公开岗位列表，不查询测评结果、不生成个性化分；企业仍可维护岗位画像，为灰度开启做准备。 |
||||
|
|
||||
|
开关开启时规则版本为 `job-recommendation-v0.1`。回滚只需关闭开关；画像数据保留，不删除岗位、测评、投递、评分或审计数据。 |
||||
|
|
||||
|
V39 不改变： |
||||
|
|
||||
|
- V35/V36 的题库、答题、重测、有效期和审计语义； |
||||
|
- V38 的候选评分开关、ABILITY 快照和 V32 排名口径； |
||||
|
- 既有 `/jobs` 搜索、`/jobs/{jobId}/match`、投递和收藏接口语义。 |
||||
|
|
||||
|
## 12. 测试与验收计划 |
||||
|
|
||||
|
### 12.1 单元测试 |
||||
|
|
||||
|
- RIASEC 与四维能力来源选择：最新优先、过期回退、结构异常不抛 500； |
||||
|
- 公式：单信号、双信号、三信号、缺失重归一化、`HALF_UP`、稳定排序； |
||||
|
- 硬过滤：未发布、已投递、城市不符、薪资不符； |
||||
|
- 理由/建议白名单和最大数量； |
||||
|
- 受控分类父子校验、画像字段边界、启用条件和审核状态机； |
||||
|
- 反馈幂等、撤销、不感兴趣过滤和理由反馈不改变推荐分； |
||||
|
- 画像、反馈和审核的乐观锁冲突。 |
||||
|
|
||||
|
### 12.2 MockMvc 与持久化测试 |
||||
|
|
||||
|
- STUDENT/COMPANY/ADMIN/未登录权限矩阵； |
||||
|
- 企业只能读写自己的岗位画像，更新后必须进入待审核状态； |
||||
|
- ADMIN 只能审核、不可修改企业画像内容；非 ADMIN 审核返回 403； |
||||
|
- 分类接口仅返回受控字典；自由行业/岗位族编码返回 400； |
||||
|
- 推荐响应不含测评题目、答案、答案键、结果 ID、原始画像权重； |
||||
|
- 无画像/无测评返回 `FALLBACK`，不伪造个性化分； |
||||
|
- 分页参数、空列表、推荐总数和稳定排序； |
||||
|
- 查询次数固定，禁止推荐列表 N+1； |
||||
|
- 不写 `candidate_dimension_scores`、不改变 V32 排名。 |
||||
|
|
||||
|
### 12.3 MySQL/Docker 黑盒 |
||||
|
|
||||
|
1. 执行 V37 迁移，校验三张表、唯一约束、外键、范围约束、分类种子和索引； |
||||
|
2. 企业创建/更新自己岗位画像，其他企业返回 403，ADMIN 审批后才可用于推荐； |
||||
|
3. 学生完成 RIASEC 和能力测评后，推荐分与理由符合固定 fixture； |
||||
|
4. 验证历史高分、最新低分和能力过期三种选择口径； |
||||
|
5. 开关关闭返回 `FALLBACK`，开启后才产生 `PERSONALIZED`； |
||||
|
6. 已投递、明确不感兴趣、关闭、城市/薪资不符岗位不会进入个性化列表； |
||||
|
7. 反馈重复提交、同键重放、撤销重试和审核并发均满足预期业务码； |
||||
|
8. 响应和审计不泄露题目、答案、评分规则、结果 ID 或凭据； |
||||
|
9. RabbitMQ 队列终态正常，并回归 V34–V38 关键接口。 |
||||
|
|
||||
|
冻结条件：全量 `mvn clean verify`、运行时/静态 OpenAPI 对账、真实 MySQL/Docker 黑盒关键项全部 PASS，且 FAIL=0。 |
||||
|
|
||||
|
## 13. 已确认决策与编码前最后口径 |
||||
|
|
||||
|
负责人已确认： |
||||
|
|
||||
|
1. 新增岗位推荐画像与 Flyway `V37__job_recommendation_profiles.sql`； |
||||
|
2. 接受默认排序权重：偏好 40%、RIASEC 35%、能力 25%； |
||||
|
3. 无结构化岗位画像时仅返回 `FALLBACK`，不伪造测评推荐； |
||||
|
4. 任何已有投递的岗位均不再推荐； |
||||
|
5. 默认关闭 `recommendation.assessment.enabled`，支持灰度； |
||||
|
6. 第一版加入学生“不感兴趣”持久化和推荐理由反馈； |
||||
|
7. 按负责人第 8 项“是”处理：第一版需要 ADMIN 审核企业岗位画像。 |
||||
|
|
||||
|
基于第 6、7 项，原先的 3 个 operation 扩展为 8 个 operation，且迁移包含三个相关表。这是已确认产品范围变化，不是无关扩张。 |
||||
|
|
||||
|
编码开始前只需最终确认以下两项具体口径： |
||||
|
|
||||
|
1. 受控分类采用“平台种子维护、企业只能选择、不允许自由输入”，并按 `job-taxonomy-v0.1` 首批目录落库； |
||||
|
2. ADMIN 审核语义确为“企业提交/更新画像后进入 `PENDING_REVIEW`，审核通过才参与推荐”。 |
||||
|
|
||||
|
若以上两项确认，即可进入 V39 编码；在此之前不得创建迁移、Controller 或前端接口实现。 |
