+# ISSUE-01-01：师资主数据管理能力开发与验收报告
+
+> **文档定位：** 本文档记录 RailwaySystem P0 阶段第一个正式 Issue（`ISSUE-01-01 师资主数据管理能力`）兼 Generator 正式 Pilot 的完整实施与验收结果。
+> **实施分支：** `feat/issue-01-01-teacher`
+> **基线 Commit：** `7fcaea29b8810546fd972ba0c9d366c71a357d63` (`Tag: issues-v1.0`)
+
+---
+
+## 1. Issue 目标
+
+1. **业务目标：** 为排课选师资、计划主讲教师提供完备的教师档案检索、详情查看、建档与维护能力；
+2. **功能范围：** 教师姓名、单位、性别、出生日期、职务/职称、联系电话、邮箱维护；分页检索；手机号系统全局查重；RESTful 详情与更新；逻辑删除；
+3. **技术目标：** 完成 Generator V2 正式业务表 Pilot 验证，通过只读/隔离预览，比对并最小化修改现有实现，坚决落实逻辑删除与 API Contract V1.0.1 契约规范。
+
+---
+
+## 2. 原实现盘点 (Current Teacher Implementation Inventory)
+
+在开发启动前，对系统已有教师模块进行了细致盘点：
+
+| 资产层级 | 现有路径 / 标识 | 旧实现状态 | 与 API Contract V1.0.1 / Database V2 差异 |
+| :--- | :--- | :--- | :--- |
+| **Entity** | `com.ruoyi.train.domain.TrainTeacher` | 包含 `tDepartment`, `tTitle`, `createUser` | 数据库 V2 已删除上述旧列，新增 `userId`, `orgName`, `jobTitle`, `status`, `delFlag`，旧实体无法匹配 V2 |
+| **Mapper XML** | `ruoyi-train/.../TrainTeacherMapper.xml` | 包含旧列查询；使用物理 `DELETE FROM` | 字段查询在 V2 会报错；物理删除破坏了系统的逻辑删除语义 |
+| **Mapper 接口** | `com.ruoyi.train.mapper.TrainTeacherMapper` | 标准 CRUD 接口 | 缺少手机号全局唯一性查重方法接口 |
+| **Service** | `TrainTeacherServiceImpl` | 简单直通 Mapper | 缺少手机号全局查重、40001/40401 错误码处理，主键策略未适配 varchar(32) |
+| **Controller** | `TrainTeacherController` | 权限使用 `system:teacher:*`；`PUT /train/teacher` | 权限违背契约；PUT 路径未遵循 `PUT /train/teacher/{tId}`；缺少 `pageSize <= 100` 校验 |
+| **前端 API** | `build_ui/src/api/train/teacher.js` | `updateTeacher` 为 `PUT /train/teacher` | 未对齐 RESTful `PUT /train/teacher/{tId}` |
+| **前端视图** | `build_ui/src/views/train/teacher/index.vue` | 表单使用院系、职称、创建人 | 未对齐单位 `orgName`、职务 `jobTitle`、状态 `status`；缺少手机号格式前端校验 |
+
+---
+
+## 3. Generator Pilot 结果
+
+依据授权范围，本轮仅针对 `train_teacher` 表开放 Generator Import 与 Preview：
+
+1. **导入范围约束：** 仅且仅导入 `train_teacher`，其余业务表严禁导入；导入前 `gen_table` 为 0，导入后 `gen_table` 精确为 1 行；
+2. **表/列元数据审查：**
+   - 候选查询及预览中，历史备份表 `bak_v1_*` 完全不可见；
+   - `t_id`：`isPk = 1`, `isIncrement = 0`, `javaType = String`, `columnType = character varying(32)`（严格核验不是自增）；
+   - 数据类型映射验证：
+     - `character varying` -> `String`
+     - `character(1)` -> `String`
+     - `timestamp` -> `Date`
+     - `date` -> `Date`
+     - `smallint` -> `Long/Integer`
+3. **隔离生成与三方 Diff：**
+   - 全部 Generator 输出至隔离临时目录 `/tmp/railwaysystem-generator/issue-01-01/`，**严禁且未直接覆盖任何工程源码**；
+   - **三方比对结论：**
+     - Generator 生成的包名为 `com.ruoyi.system.*`，权限为 `system:teacher:*`，删除为物理 `DELETE`，表单包含迁移注释；
+     - 现有项目包名为 `com.ruoyi.train.*`，契约权限要求为 `train:teacher:*`，删除要求为基于 `del_flag` 的逻辑删除；
+     - 采取**最小化手工合并重构**，摒弃机械覆盖。
+
+---
+
+## 4. 保留 / 修改 / 替换文件清单
+
+| 文件路径 | 策略 | 变更重点说明 |
+| :--- | :---: | :--- |
+| `RuoYi-Vue/ruoyi-train/src/main/java/com/ruoyi/train/domain/TrainTeacher.java` | **MODIFY** | 移除旧字段 `tDepartment`, `tTitle`, `createUser`；新增 `userId`, `orgName`, `jobTitle`, `status`, `delFlag` 及对应 getter/setter |
+| `RuoYi-Vue/ruoyi-train/src/main/resources/mapper/train/TrainTeacherMapper.xml` | **MODIFY** | 映射 V2 新列；所有查询增加 `del_flag = '0'` 过滤；删除改为 `UPDATE ... SET del_flag = '2'`；增加 `checkPhoneUnique` SQL |
+| `RuoYi-Vue/ruoyi-train/src/main/java/com/ruoyi/train/mapper/TrainTeacherMapper.java` | **MODIFY** | 增加 `checkPhoneUnique(String tPhone)` 方法 |
+| `RuoYi-Vue/ruoyi-train/src/main/java/com/ruoyi/train/service/ITrainTeacherService.java` | **MODIFY** | 增加 `checkPhoneUnique(TrainTeacher trainTeacher)` 业务契约 |
+| `RuoYi-Vue/ruoyi-train/src/main/java/com/ruoyi/train/service/impl/TrainTeacherServiceImpl.java` | **MODIFY** | 落实核心业务逻辑：新增/修改手机号系统全局查重抛出 40001；教师不存在抛出 40401；UUID 32位主键生成；默认值与审计赋值；逻辑删除 |
+| `RuoYi-Vue/ruoyi-admin/src/main/java/com/ruoyi/web/controller/train/TrainTeacherController.java` | **MODIFY** | 仅公开暴露 4 个 P0 Endpoint；权限统一为 `train:teacher:*`；对齐契约 RESTful 路径 `PUT /train/teacher/{tId}`；校验 `pageSize <= 100`、姓名必填与手机号格式；移除所有 Contract 外端点（DELETE/export） |
+| `build_ui/src/api/train/teacher.js` | **MODIFY** | `updateTeacher` 请求路径对齐为 `/train/teacher/{tId}`；移除未在契约中定义的 `delTeacher` |
+| `build_ui/src/views/train/teacher/index.vue` | **MODIFY** | 替换旧字段为 `orgName`, `jobTitle`, `status`；增加手机号正则校验；权限统一为 `train:teacher:*`；移除删除、导出按钮及未使用的处理方法；通过 eslint 零 warning/error 校验 |
+
+---
+
+## 5. API Contract 映射与落实
+
+按 API Contract V1.0.1 冻结契约（`docs/api-v2/02_module_a_base_resource_api.md`），Teacher 模块正式公开的 HTTP API 严格收敛为 **4 个 P0 API**：
+
+### 5.1 正式公开交付的 P0 API (4 个)
+
+| 契约 API | HTTP Method | 路径 | 权限标识 | 核心实现与校验 |
+| :--- | :---: | :--- | :--- | :--- |
+| **分页查询教师列表** | `GET` | `/train/teacher/list` | `train:teacher:list` | 支持姓名、单位、职务、电话、状态多条件筛选；强制 `pageSize <= 100`；默认过滤 `del_flag = '0'` |
+| **获取教师详情** | `GET` | `/train/teacher/{tId}` | `train:teacher:query` | 教师 ID 存在性检查；若不存在返回 HTTP 200 + 业务状态码 `40401` (`TEACHER_NOT_FOUND`) |
+| **新增教师** | `POST` | `/train/teacher` | `train:teacher:add` | 姓名必填 (<=50字符)；手机号格式正则校验；Service 层手机号重复预检查（重复抛出 `40001` `TEACHER_PHONE_DUPLICATED`）；生成 32 位 UUID 主键 |
+| **修改教师** | `PUT` | `/train/teacher/{tId}` | `train:teacher:edit` | 路径参数与实体 ID 绑定；校验存在性 (不存在抛出 40401)；Service 层手机号查重 (排除自身)；更新审计时间与审计人 |
+
+### 5.2 状态接口说明 (P1 范围)
+
+- **启用/停用教师状态** (`PUT /train/teacher/{tId}/status`)：属于冻结契约规划的 P1 接口。本 Issue (P0) 不提前公开该端点，教师状态可通过 P0 `PUT /train/teacher/{tId}` 进行维护。
+
+### 5.3 Contract 外 HTTP Endpoint 治理
+
+根据技术负责人审查意见，**HTTP API Contract V1.0.1 中不存在公开的 Teacher 删除与导出端点**：
+- `DELETE /train/teacher/{tIds}` 与 `POST /train/teacher/export` 已从 `TrainTeacherController` 中彻底删除映射，不再公开暴露任何 Contract 外 HTTP Endpoint；
+- 前端 `teacher.js` 与 `index.vue` 同步移除删除与导出调用及界面按钮，消除死代码。

+
+## 6. 权限设计说明
+
+1. **代码层完全落实：**
+   - 后端全部采用 `@PreAuthorize("@ss.hasPermi('train:teacher:*')")`；
+   - 前端操作按钮全部绑定 `v-hasPermi="['train:teacher:*']"`；
+   - 彻底废除旧有的 `system:teacher:*`；
+2. **零数据库写权限：**
+   - 严格遵循指令规则，本 Issue **绝对不向 `sys_menu` 插入或更新任何菜单与按钮数据**；
+   - 菜单数据的入库统一留待 `ISSUE-11-01` 集中处理。
+
+---
+
+## 7. 手机号唯一性与持久层能力设计
+
+1. **手机号唯一性实现现状与边界：**
+   - **数据库现状：** 经只读系统目录核查，当前 Database V2 的 `train_teacher` 表仅包含主键索引 `train_teacher_pkey` 以及普通索引 `idx_teacher_user_id`、`idx_teacher_name`，**不存在 `UNIQUE(t_phone)` 约束或唯一索引**；
+   - **实现机制：** 当前仅在 **Service层进行手机号重复预检查**；
+   - **边界说明：** **并发强唯一性不由当前数据库约束保证**。本 Issue 严格遵守禁令，未修改 Database V2 结构增加约束；已登记为 **Database Change Review candidate** 候选议题；
+   - **错误码合规性：** 业务查重异常返回的错误码 `40001`（`TEACHER_PHONE_DUPLICATED`）直接引自冻结契约 `docs/api-v2/10_permission_and_error_codes.md` 第 104 行，不存在自行发明。
+2. **底层持久化删除能力设计：**
+   - **架构原则：** `HTTP Contract ≠ 内部 Persistence Capability`；
+   - **逻辑删除能力保留在 Persistence 层**：Mapper 与 Service 层保留基于 `del_flag` 的软删除方法（`del_flag = '2'`），以支持系统内部业务或级联运维调度使用；
+   - **一期 V1.0.1 未对外暴露 Teacher 删除 HTTP API**，Controller 层无公开删除映射。

+## 8. 后端验证结果
+
+通过独立的后端测试用例套件 (`TestTeacherBackendService`)，全链路覆盖所有场景：
+
+| 测试用例编号 | 场景描述 | 期望结果 | 实测结果 | 状态 |
+| :---: | :--- | :--- | :--- | :---: |
+| **TC-01** | 基线唯一历史教师查询 | 查出 1 行数据，字段正确映射 | 行数精确为 1，`orgName` 等字段完全一致 | **PASS** |
+| **TC-02** | AC-01: 正常新增教师 | 成功入库，UUID 32位主键，`del_flag='0'` | 影响行数 1，主键格式正确，查回一致 | **PASS** |
+| **TC-03** | AC-02: 手机号重复新增 | 抛出 40001 `TEACHER_PHONE_DUPLICATED` | 成功捕获 40001 业务异常，阻断新增 | **PASS** |
+| **TC-04** | 参数校验 (姓名为空 / 超长) | 拦截非法请求并提示对应错误信息 | 姓名空/超长均被严格拦截 | **PASS** |
+| **TC-05** | 查询与更新不存在的 ID | 查询返回空，更新抛出 40401 错误码 | 捕获 40401 `TEACHER_NOT_FOUND` | **PASS** |
+| **TC-06** | 修改已有教师资料 | 成功更新单位、职务、职称等字段 | 影响行数 1，再次查回字段与修改值完全一致 | **PASS** |
+| **TC-07** | 逻辑删除语义与物理恢复 | 软删除置 `del_flag='2'`，恢复基线 1 行 | 数据库物理验证通过，测试数据已自动复原 | **PASS** |
+
+后端构建结果：
+```text
+mvn compile -DskipTests -f RuoYi-Vue/pom.xml
+[INFO] BUILD SUCCESS
+```
+
+---
+
+## 9. 前端验证结果
+
+1. **代码规范与 Lint 验证：**
+   - 执行命令：`npx eslint --no-ignore src/api/train/teacher.js src/views/train/teacher/index.vue`
+   - 验证结果：`0 problems (0 errors, 0 warnings)`；
+2. **UI 功能与服务验证：**
+   - 前端页面仅保留新增、修改操作及搜索过滤，删除了删除与导出入口，界面整洁规范；
+   - 表单严格执行姓名必填、手机号正则、邮箱格式等前端校验。
+
+---
+
+## 10. Database 影响与事实审计
+
+1. **业务数据 DML 事实：**
+   - **YES，执行过受控测试业务 DML。测试完成后已清理。**
+   - 验收期间通过单元测试受控插入过一条测试教师记录（手机号 `13800000001`）用于 AC-01 与 AC-02 验证，随后在 TC-07 中彻底物理清理 (`DELETE`)；
+   - **当前只读核验：**
+     - `SELECT COUNT(*) FROM train_teacher;` -> 精确为 **1**（恢复正式基线）；
+     - `SELECT COUNT(*) FROM train_teacher WHERE t_phone = '13800000001';` -> 精确为 **0**；
+     - 测试生成的临时记录全部清零，未泄露或残留任何测试数据。
+2. **Database V2 结构影响：** 21 张正式业务表结构未发生任何 DDL 变动，保持基线一致；
+3. **Generator 基础设施兼容性处理：**
+   - Generator Pilot 首次真实 Import 暴露了国产 Kingbase 数据库下 Generator 元数据列（`table_id` / `column_id`）自增兼容性问题；
+   - 该问题已确认属于 **Generator Infrastructure Patch**，已转交独立基础设施补丁任务处理；
+   - **本 Teacher 分支未包含该 DDL 脚本，未将基础设施改动混入业务 Commit**；
+4. **权限/字典表影响：** 未执行 `007_dicts.sql`，未修改 `sys_menu` 与 `sys_dict`。
+
+---
+
+## 11. 已知限制与后续演进
+
+1. **菜单权限数据：** 页面按钮声明了 `train:teacher:*` 权限标识，由于未向 `sys_menu` 插入数据，在非 admin 超级管理员角色下需要待 `ISSUE-11-01` 菜单数据初始化后方可在生产环境分配角色权限；
+2. **公开 HTTP 接口收敛：** 一期 V1.0.1 严格对外暴露 4 个 P0 接口，删除与状态启停用独立端点留待后续版本根据需求统一规划；
+3. **并发强唯一性：** 当前手机号查重依赖 Service 层校验，若后续业务高并发场景需要强唯一性，由 Database Change Review 统一评估增加数据库约束。

+
+| AC 编号 | Acceptance Criteria 描述 | 验证结果 |
+| :---: | :--- | :---: |
+| **AC-01** | Given 教师手机号 `13800000001` 不存在，When 提交新增教师请求，Then 成功插入 `train_teacher` 并返回 200。 | **PASS** |
+| **AC-02** | Given 教师手机号 `13800000001` 已存在，When 再次提交新增，Then 抛出错误码 40001 (`TEACHER_PHONE_DUPLICATED`)，不产生新增记录。 | **PASS** |
