# 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

            return result;
        }
        return null;
    } catch (Exception e) {
        log.warn("AiGateway recognizeFood 调用失败: {}", e.getMessage());
        recordFailure();
        return null;
    }
}

/**
 * 生成菜单
 */
public String generateMenu(String selectedFoodsJson, String participantsJson, String date) {
    if (!enabled || isCircuitOpen()) return null;
    
    try {
        ObjectNode body = objectMapper.createObjectNode();
        body.put("selected_foods", selectedFoodsJson);
        body.put("participants", participantsJson);
        body.put("date", date);
        
        HttpEntity<String> entity = new HttpEntity<>(body.toString(), createJsonHeaders());
        String url = baseUrl + "/api/v1/menu/generate";
        
        ResponseEntity<String> response = restTemplate.postForEntity(url, entity, String.class);
        
        if (response.getStatusCode().is2xxSuccessful() && response.getBody() != null) {
            JsonNode root = objectMapper.readTree(response.getBody());
            consecutiveFailures.set(0);
            return root.has("menu_json") ? root.get("menu_json").asText() : response.getBody();
        }
        return null;
    } catch (Exception e) {
        log.warn("AiGateway generateMenu 调用失败: {}", e.getMessage());
        recordFailure();
        return null;
    }
}
```
