+# 饮食模块实现计划
+
+> **面向 AI 代理的工作者：** 必需子技能：使用 superpowers:subagent-driven-development（推荐）或 superpowers:executing-plans 逐任务实现此计划。步骤使用复选框（`- [ ]`）语法来跟踪进度。
+
+**目标：** 构建饮食模块后端 API，包括调研表、食材推荐、食谱生成、饮食记录、共餐配置等核心功能。
+
+**架构：** 基于现有菌群报告体系和家庭体系扩展，新增 6 张表 + 5 个 Controller + 4 个 Service。AI 识别和菜单生成复用 AiGateway（LangGraph 接入）。
+
+**技术栈：** Spring Boot 2.7.18 + MyBatis-Plus + Java 8 + LangGraph Python 服务

+
+## 4. 核心流程
+
+### 4.1 调研引导流程
+
+```
+用户首次进入 /pages/diet/index
+  ↓
+GET /api/diet/preferences/current-member
+  → 无记录 → 返回 404
+  ↓
+前端弹"调研引导弹窗"
+  → 必填：过敏原、绝对忌口、宗教饮食
+  → 可选：辣度、口味、菜系、烹饪方式
+  → 系统推荐目标（基于 disease_risks）→ 用户确认
+  ↓
+POST /api/diet/preferences/save
+  → 写入 diet_preferences，filled_at = now()
+  → goal_confirmed 字段记录是否确认
+  ↓
+首页刷新，显示推荐食材
+```
+
+### 4.2 食材推荐流程
+
+```
+用户进入饮食首页
+  ↓
+GET /api/diet/ingredients/suggest
+  → 查 meal_configs → participant_member_ids
+  → 查每个 member 的 diet_preferences + health_gut_flora
+  → 过滤禁忌食材（过敏+忌口+宗教）
+  → 计算推荐分：
+    - food_recommend_idx 评分（0-100）
+    - bacteria_food_mapping 映射加分/减分
+    - 目标匹配加权
+  → 返回 Top 15 食材列表（含推荐理由）
+  ↓
+前端展示"已选食材"列表（会话内）
+  → 用户可：换一批 / 添加 / 删除
+  ↓
+POST /api/diet/ingredients/recommend（换一批）
+  → 同 get suggest，但随机种子变化
+  ↓
+POST /api/diet/ingredients/add（添加食材）
+  Body: { food_id, name }
+  → 前端会话内追加，不持久化
+  ↓
+POST /api/diet/ingredients/remove（删除食材）
+  Body: { food_id }
+  → 前端会话内移除
+  ↓
+POST /api/diet/ingredients/confirm（确认并生成食谱）
+  Body: { selected_foods: [{food_id, name}], date: "2026-08-06" }
+  → 调 AiGateway.generateMenu(selected_foods, participants, date)
+    → LangGraph 文本节点生成菜品 + 克数（按人数自动算）
+  → 写入 diet_recommendations（version=1）
+  → 返回推荐方案
+```
+
+### 4.3 饮食记录流程
+
+```
+用户点击"今日饮食" → 拍早餐
+  ↓
+uni.chooseImage → 上传 OSS → 拿到 image_url
+  ↓
+POST /api/diet/record/recognize
+  Body: { image_url }
+  → AiGateway.recognizeFood(image_url)
+    → LangGraph 视觉节点识别食材 + 置信度
+    → 输出：[{name, confidence, category}]
+  → 返回识别结果
+  ↓
+前端展示"AI 识别结果"列表，用户可勾选/修改/增删
+  ↓
+POST /api/diet/record/save
+  Body: {
+    member_id, meal_type, record_method: "photo",
+    image_url, ai_recognized_foods, user_confirmed_foods
+  }
+  → 写入 diet_records + diet_record_items
+  → 返回记录 ID
+  ↓
+前端跳转到"今日饮食记录"页
+```
+
+### 4.4 目标自动推断流程
+
+```
+用户填写调研表时，系统推荐健康目标：
+  ↓
+查 family_member 对应 user 的 health_reports.disease_risks
+  ↓
+规则映射：
+  - 糖尿病高风险 → 推荐 "控糖"
+  - 肥胖 → 推荐 "减脂"
+  - 肠道菌群失衡（gut_balance_score < 60） → 推荐 "肠道调理"
+  - 高血压 → 推荐 "低钠"
+  ↓
+输出推荐目标列表 → 前端展示"系统推荐目标：减脂 + 肠道调理"
+  → 用户确认 → 写入 diet_preferences.health_goals，goal_confirmed=1
+  → 用户不确认 → 留空，后续手动填
+```
+
+---
+
+## 5. AI 网关扩展
+
+### 5.1 `AiGateway.recognizeFood(imageUrl)`
+
+```
+POST /api/ai/food/recognize
+  Body: { image_url: "https://..." }
+
+AiGatewayService.recognizeFood(imageUrl)
+  → prompt: "识别图片中的主要食材，返回 JSON 格式：[{name, confidence, category}]"
+  → 调 LangGraph /api/v1/chat/process（视觉节点）
+  → fallback：失败时返回空数组
+  → 返回：{ foods: [{name, confidence, category}], raw_response }
+```
+
+**约束**：
+- 不引入新模型，复用现有 LangGraph 工作流
+- 图片先传到 OSS（复用健康报告上传流程）
+- 单次调用超时 3s，超时降级为纯手动
+
+### 5.2 `AiGateway.generateMenu(selectedFoods, participants, date)`
+
+```
+POST /api/ai/menu/generate
+  Body: {
+    selected_foods: [{food_id, name}],
+    participants: [member_ids],
+    date: "2026-08-06"
+  }
+
+AiGatewayService.generateMenu(selectedFoods, participants, date)
+  → prompt: "根据以下食材和用餐人数，生成一日三餐菜单..."
+    输入：
+    - 食材列表
+    - 用餐人数（participants.length）
+    - 日期
+    - 营养目标（从 diet_preferences.health_goals 取）
+    - 禁忌（从 allergies + absolute_avoid + religious_diet 取）
+  → LangGraph 文本节点生成菜单
+  → 输出：{ meals: [{name, ingredients: [{name, grams}], cooking_method, nutrition}] }
+  → 返回 menu_json
+```
+
+**克数自动计算**：AI 根据 `participants.length` 自动推算克数，无需前端传入。
+
+---
+
+## 6. 后端 API 设计
+
+### 6.1 新增 Controller
+
+```
+DietPreferencesController
+  POST /api/diet/preferences/current-member  → 查当前成员调研表

+  POST /api/diet/ingredients/recommend       → 换一批
+  POST /api/diet/ingredients/add             → 手动添加食材（会话内）
+  POST /api/diet/ingredients/remove          → 删除食材
+  POST /api/diet/ingredients/confirm         → 确认食材，生成食谱
+

+
+DietRecordController
+  POST /api/diet/record/recognize            → AI 识别图片食材
+  POST /api/diet/record/save                 → 保存饮食记录
+  POST /api/diet/record/daily                → 查今日饮食汇总
+  POST /api/diet/record/weekly               → 查本周趋势
+
+DietMealConfigController

+  POST /api/diet/meals/config/save           → 保存共餐配置
+```
+
+### 6.2 响应结构（统一）
+
+```json
+{
+  "code": 200,
+  "message": "success",
+  "data": { ... }
+}
+```
+
+---
+
+## 7. 前端页面规划
+
+### 7.1 分包结构
+
+在 `pages.json` 的 `subPackages` 中注册 `pages/diet/`：
+
+```json
+{
+  "subPackages": [
+    {
+      "root": "pages/diet",
+      "pages": [
+        { "path": "index", "style": { "navigationBarTitleText": "饮食" } },

+      ]
+    }
+  ]
+}
+```

+```
+
+---
+
+## 9. 实施计划（待细化）
+
+### Phase 1：数据模型 + 后端基础
+- [ ] 执行迁移（7 张表/字段变更）
+- [ ] 实现 `DietPreferencesController` + `DietPreferencesService`
+- [ ] 实现 `DietIngredientController` + `BeijingNutritionService.generateIngredientList()`
+- [ ] 实现 `DietRecommendationController` + `DietRecommendationService`
+- [ ] `mvn clean compile` 验证
+
+### Phase 2：AI 扩展
+- [ ] 实现 `AiGateway.recognizeFood()`（视觉节点）
+- [ ] 实现 `AiGateway.generateMenu()`（文本节点）
+- [ ] 实现 `DietRecordController` + `DietRecordService`
+- [ ] 测试识别链路（失败降级）
+
+### Phase 3：前端
+- [ ] 注册 `pages/diet/` 分包
+- [ ] 实现 `pages/diet/index.vue`（食材推荐器）
+- [ ] 实现 `pages/diet/preferences.vue`（调研表）
+- [ ] 实现 `pages/diet/recommendation.vue`（食谱展示）
+- [ ] 实现 `pages/diet/records.vue`（饮食记录）
+- [ ] 实现其他 3 个页面
+
+### Phase 4：集成测试
+- [ ] 端到端流程测试（调研 → 推荐 → 生成 → 记录）
+- [ ] 边界测试（无调研表、无菌群报告、无共餐配置）
+- [ ] 性能测试（AI 识别延迟、批量推荐）
+

+
+## 10. 规格自检
+
+| 检查项 | 结果 |
+|--------|------|
+| 占位符扫描 | ✅ 无"待定"/"TODO" |
+| 内部一致性 | ✅ 数据流、接口、页面逻辑自洽 |
+| 范围检查 | ✅ 聚焦单一模块，不混入无关功能 |
+| 模糊性检查 | ✅ 每个需求有唯一解释 |
+| 迁移工作流 | ✅ 符合 AGENTS.md 规范（ensureColumn + schema.sql 同步） |
+| 接口规范 | ✅ 全部用 @PostMapping |
+| Bean 命名 | ✅ 新 Controller/Service 无重名风险 |
+| 小程序限制 | ✅ 未使用可选链/CSS Grid/:key 表达式 |
