+> **关联模块：** `ISSUE-01-03 课程库基础资料管理`

+> **开发基线：** `55143af4a518222007d9b82dfbe0677a04f06150`  
+> **API Contract：** `docs/api-v2/02_module_a_base_resource_api.md`  
+> **数据库：** KingbaseES / Database V2

+
+---
+
+## 1. 功能目标与范围
+
+本功能将课程维护改造为两步式向导，并补齐课程与教学资源之间的真实关联能力：
+
+1. 第一步维护课程编码、名称、类型、学时、教学目标、课程内容、状态与备注；
+2. 第二步查看已关联资源、关联资源库中的既有资源、上传新资源并自动关联、解除资源关联；
+3. 课程与资源使用规范化多对多关联表 `train_course_resource`，禁止在 `train_course` 中保存逗号分隔资源 ID；
+4. 复用既有课程、教学资源与通用文件上传能力，不引入新的文件存储协议；
+5. 不修改培训计划课程配置、排课及其他计划流程模块。
+
+### 1.1 明确边界
+
+- 解除关联只删除 `train_course_resource` 关系，不删除 `train_resource` 资源记录及实际文件；
+- 被课程引用的资源禁止直接删除，必须先解除课程关联；
+- 本功能不提供资源文件物理删除、资源版本管理、断点续传及大文件分片上传；
+- 本功能未执行真实生产数据库迁移或写入。
+
+---
+
+## 2. 用户操作流程
+
+### 2.1 新增课程
+
+1. 用户点击“新增”；
+2. 在“课程基本信息”步骤填写并保存课程；
+3. 后端返回已生成 `cId`，前端进入“教学资源”步骤；
+4. 用户可关联既有资源，或通过通用上传组件上传文件、创建资源并自动绑定；
+5. 用户点击“完成”关闭向导并刷新课程列表。
+
+### 2.2 修改课程
+
+1. 用户从列表进入“修改”；
+2. 页面加载课程详情及其真实资源列表；
+3. 用户可修改课程基本信息，也可进入第二步新增或解除资源关联；
+4. 解除关联不会删除资源库中的资源。
+
+---
+
+## 3. 数据模型与设计决策
+
+### 3.1 规范化关联模型
+
+课程与资源采用标准 N:M 模型：
+
+```text
+train_course (1) ──< train_course_resource >── (1) train_resource
+```
+
+`train_course_resource` 核心字段：
+
+| 字段 | 类型 | 说明 |
+|---|---|---|
+| `id` | `BIGINT IDENTITY` | 关联记录主键 |
+| `c_id` | `VARCHAR(32)` | 课程 ID，外键指向 `train_course.c_id` |
+| `resource_id` | `VARCHAR(32)` | 资源 ID，外键指向 `train_resource.resource_id` |
+| `sort_no` | `INTEGER` | 课程内资源排序号 |
+| `create_by` | `VARCHAR(64)` | 创建人 |
+| `create_time` | `TIMESTAMP` | 创建时间 |
+
+唯一约束为 `(c_id, resource_id)`，防止同一资源被重复绑定到同一课程。
+
+### 3.2 旧字段兼容迁移
+
+迁移脚本兼容曾执行旧版 011 的环境：
+
+1. 检测 `train_course.resource_id` 是否存在；
+2. 将逗号分隔的资源 ID 拆分后迁移到 `train_course_resource`；
+3. 忽略不存在或已逻辑删除的资源；
+4. 使用唯一约束避免重复迁移；
+5. 完成迁移后删除 `train_course.resource_id` 非规范字段。
+
+---
+
+## 4. API 与权限
+
+### 4.1 本次新增或调整的课程接口
+
+| HTTP Method | Path | 权限 | 说明 |
+|:---:|---|---|---|
+| `GET` | `/train/course/{cId}` | `train:course:query` | 返回 `CourseDetailVO`，其中 `resources` 为真实关联资源列表 |
+| `POST` | `/train/course` | `train:course:add` | 新增课程并在 `data` 中返回包含生成后 `cId` 的课程对象 |
+| `POST` | `/train/course/{cId}/resources` | `train:course:edit` | 绑定资源；请求体为 `resourceId`、`sortNo` |
+| `DELETE` | `/train/course/{cId}/resources/{resourceId}` | `train:course:edit` | 解除课程资源关联，不删除资源本身 |
+
+### 4.2 复用的资源接口
+
+| HTTP Method | Path | 权限 | 用途 |
+|:---:|---|---|---|
+| `GET` | `/train/resource/list` | `train:resource:list` | 获取可关联资源 |
+| `POST` | `/train/resource` | `train:resource:edit` | 创建教学资源并返回生成后的资源对象 |
+| `POST` | `/common/upload` | 登录用户 | 复用通用上传组件上传资源文件 |
+
+### 4.3 请求模型
+
+`CourseResourceBindDTO`：
+
+| 字段 | 校验 | 说明 |
+|---|---|---|
+| `resourceId` | `@NotBlank` | 必填资源 ID |
+| `sortNo` | `@Min(0)` | 可选排序号，默认 0 |
+
+---
+
+## 5. 后端实现
+
+| 层级 | 文件 | 实现内容 |
+|---|---|---|
+| Controller | `TrainCourseController` | 返回新增课程对象；增加资源绑定、解绑端点 |
+| Controller | `TrainResourceController` | 新增资源后返回包含 `resourceId` 的资源对象 |
+| DTO | `CourseResourceBindDTO` | 绑定请求参数与校验 |
+| VO | `CourseDetailVO` | `resources` 调整为 `List<TrainResource>` |
+| Service | `TrainCourseResourceServiceImpl` | 校验课程和资源、幂等绑定、更新排序、解除关联 |
+| Service | `TrainCourseServiceImpl` | 查询课程详情时聚合真实资源列表 |
+| Service | `TrainResourceServiceImpl` | 删除前检查课程引用并给出友好提示 |
+| Mapper | `TrainCourseResourceMapper` | 关联查询、新增、更新、删除与引用计数 |
+| Mapper XML | `TrainCourseResourceMapper.xml` | 实现规范化关联 SQL，并过滤已逻辑删除资源 |
+| Entity/Mapper | `TrainCourse`、`TrainCourseMapper.xml` | 移除旧 `resourceId/resource_id` 逗号串字段 |
+
+绑定操作的业务语义为幂等：若关联已存在，则更新 `sort_no`，不重复插入关联记录。
+
+---
+
+## 6. 前端实现
+
+主要页面：`build_ui/src/views/train/course/index.vue`
+
+实现内容：
+
+1. 使用 `el-steps` 提供“课程基本信息 → 教学资源”两步流程；
+2. 新增课程时先保存课程并取得后端生成的 `cId`；
+3. 展示真实关联资源及其文件/链接；
+4. 支持搜索并关联资源库中尚未绑定的资源；
+5. 非外部链接资源复用 `file-upload` 组件；
+6. 外部链接校验必须以 `http://` 或 `https://` 开头；
+7. 上传资源后调用既有资源新增接口，再调用课程资源绑定接口；
+8. 支持解除关联，并明确提示资源本身不会被删除。
+
+前端 API 文件 `build_ui/src/api/train/course.js` 新增：
+
+- `bindCourseResource(cId, data)`；
+- `unbindCourseResource(cId, resourceId)`。
+
+---
+
+## 7. 数据库迁移与回滚
+
+### 7.1 正向迁移
+
+脚本：`RuoYi-Vue/sql/train/v2/011_pilot_20261010_master_data_and_resource.sql`
+
+- 幂等创建 `train_resource` 与 `train_course_resource`；
+- 创建课程资源唯一索引、课程索引与资源索引；
+- 创建课程、资源外键；
+- 迁移旧逗号 ID 后删除 `train_course.resource_id`；
+- 补齐资源类型字典、菜单与角色授权。
+
+### 7.2 回滚
+
+脚本：`RuoYi-Vue/sql/train/v2/rollback/011_pilot_20261010_master_data_and_resource_rollback.sql`
+
+回滚脚本会删除资源菜单、字典、课程资源关联表与资源表，并回滚 011 中的主数据扩展列。该操作具有破坏性，只允许在确认无正式数据的回滚窗口执行。
+
+---
+
+## 8. 自动化验证结果
+
+| 验证项 | 结果 | 说明 |
+|---|:---:|---|
+| `ruoyi-train` 全量测试 | **PASS** | 393 tests，0 failures，0 errors，0 skipped |
+| 课程资源关联定向测试 | **PASS** | 3 tests，覆盖新增绑定、重复绑定幂等更新、资源不存在拦截 |
+| 后端业务模块编译 | **PASS** | `ruoyi-train` 编译成功 |
+| 前端 ESLint | **PASS** | 课程页面与课程 API 文件 0 errors |
+| 前端生产构建 | **PASS** | `npm run build:prod` 成功 |
+| 完整 `ruoyi-admin` 本地聚合构建 | **环境阻断** | 本机缺少非公开依赖 `com.kingbase:kingbase8:8.6.0`，不是本次代码编译错误 |
+| 数据库迁移实跑 | **PENDING** | 未连接目标 Kingbase 环境执行 011 |
+| 浏览器端到端验收 | **PENDING** | 需在迁移后的集成环境验证上传、绑定、解绑完整流程 |
+
+前端构建存在一条仓库既有警告：`src/views/graph/antv/index2.vue` 使用的 `@antv/x6` 未导出 `Addon`。该警告与课程模块无关，未阻断构建。
+
+---
+
+## 9. Acceptance Criteria
+
+| AC | 验收内容 | 当前状态 |
+|:---:|---|:---:|
+| AC-01 | 新增课程保存后可进入资源步骤，且获得有效 `cId` | **STATIC/AUTOMATED PASS** |

+
+---
+
+## 10. 上线与验证顺序
+
+1. 在备份后的集成数据库执行正向迁移 011；
+2. 核对 `train_course_resource` 表、唯一约束、外键、字典和菜单；
+3. 构建并部署后端、前端；
+4. 使用具备课程及资源权限的账号进行浏览器验收；
+5. 验证新增课程、修改课程、上传资源、关联既有资源、解除关联和资源删除保护；
+6. 核对操作日志与数据库关联记录；
+7. 验收通过后再合并到目标集成分支。
+
+---
+
+## 11. Git 与交付状态
+
+- 当前代码与本文档均位于本地分支 `feat/20261009-course-wizard`；
+- 当前改动尚未执行 `git commit`、`git push` 或创建合并请求；
+- 远端页面显示的 `Status: Failed` 对应基线提交 `55143af4` 的既有 CI Pipeline，不代表本地尚未提交的课程向导代码已经执行或失败；
+- 推荐先完成本地变更审查并按中文提交规范提交，再推送该功能分支触发新的 CI；
+- 新 Pipeline 全部通过后，再向 `integration/20261010-pilot` 创建合并请求。
+
+建议提交信息：
+
+```text
+新增培训：实现课程两步式向导与教学资源关联
+```
+
+---
+
+## 12. 已知事项
+
+1. 本地完整管理端构建依赖授权的 Kingbase JDBC 驱动；CI Runner 必须先通过 `scripts/bootstrap/check-kingbase-jdbc.sh`；
+2. 当前远端失败 Pipeline 的具体失败 Job 和日志需在 GitLab Pipeline 页面查看，单凭分支页红色状态无法判断根因；
+3. 推送不会自动部署生产环境：当前 `.gitlab-ci.yml` 仅允许 `feat/cicd-pipeline` 执行 `deploy_production`，本功能分支只会运行后端、前端构建测试。

 # ISSUE-01-03 课程库基础资料管理 开发与验收文档 (A- / Final Cleanup 修订版)
 
+> **后续能力更新（2026-10-09）：** 本文记录早期课程库 P0 建设历史。其中“教学资源仅返回空列表、绑定/解绑尚未实现”等描述已被后续功能替代。当前两步式课程向导、资源上传及规范化关联的实现与验收状态，以 [`feat-20261009-course-wizard.md`](./feat-20261009-course-wizard.md) 为准。
