# foodie_server Development Guidelines

Auto-generated from all feature plans. Last updated: 2026-05-15

Tech Stack

  • 后端: Java (Spring Boot, MyBatis with XML mappers)
  • 前端: Vue.js (Element UI)
  • 支持语言: Vietnamese (vi), Simplified Chinese (zh), Traditional Chinese (tw), English (en)
  • 数据库: MySQL
  • 开发环境: Windows

Project Structure

平台管理前端代码路径:E:\QtwCode\foodie\foodie-admin-vue
商家端管理前端代码路径:E:\QtwCode\foodie\foodie-store

前端多语言(i18n)添加规范

所有前端新功能必须实现多语言,不例外。 平台管理端(foodie-admin-vue)和商家端(foodie-store) 新增的任何面向用户的文字都必须使用 $t() 而非硬编码中文。

商家端(foodie-store)使用 vue-i18n,语言文件在 src/lang/ 下(zh.js、tw.js、en.js、vi.js)。

添加多语言 key 时必须注意:

  1. 先确认 key 所属的对象层级。 语言文件中有多层嵌套对象(如 foots:{}cuxiao:{}fenlei:{} 等),使用 $t('foots.XXX') 的 key 必须添加到 foots 对象内部,不能加到文件顶部或其它对象里。
  2. 找到该对象的最后一个属性(通过 grep 或阅读文件定位),在其后追加新 key,确保逗号正确(中间属性末尾要有逗号,最后一个属性无逗号)。
  3. 四个语言文件(zh.js、tw.js、en.js、vi.js)都要添加,缺一不可。
  4. key 必须使用有意义的英文单词(驼峰命名),禁止使用 text1text2text55 等无意义序号。例如:按钮用 orderBtn,标题用 orderDialogTitle,状态用 diningStatus。四个语言文件的 key 名称必须完全一致。

曾经犯的错误:AddCategoryFirst 加到了文件第 141 行的公共区域,而 $t('foots.AddCategoryFirst') 是在 foots 对象(第 190+ 行)下查找,导致页面显示原始 key 而非翻译文本。

前端文件编辑注意事项

前端项目(foodie-store、foodie-admin-vue)的文件使用 CRLF 换行符(Windows 风格 \r\n)。使用编辑工具进行字符串替换时,由于换行符不匹配会导致 "String to replace not found" 错误。

正确做法: 编辑前端文件时,使用 Python 脚本(python << 'PYEOF')通过 content.replace() 或行号操作来修改文件内容,避免换行符匹配问题。

数据库变更管理

所有数据库变更(ALTER TABLE、数据迁移等)不直接执行,必须写入 updatesql/sql.md 文件。由开发者统一到数据库手动执行。SQL 语句需标注日期和用途注释,例如:

-- 2026-05-15 订单状态四字段分离
ALTER TABLE pos_order ADD COLUMN delivery_status BIGINT DEFAULT NULL COMMENT '配送状态';

全栈字段添加清单

添加新字段到实体时,必须按顺序更新以下所有层级:

  1. Java 实体类(Entity)
  2. MyBatis XML mapper(resultMap + 相关的 select/insert/update 语句)
  3. DTO 类(如适用)
  4. Service 层业务逻辑
  5. Controller 层接口
  6. 前端 Vue 组件
  7. 四个 i18n 语言文件(vi.js、zh.js、tw.js、en.js)
  8. SQL 迁移脚本

商家类型与订单查询逻辑

InfoUser.userType 区分不同商家角色,查询订单时必须按类型使用不同字段过滤:

userType 角色 订单过滤条件
1 普通商家 PosOrder.shId = userId
3 夜市商家 PosOrder.shId = userId
其他 摊位商家 PosOrder.mdId = InfoUser.storeId(从用户表查关联的摊位门店ID)

关键字段:

  • InfoUser.userType:0=普通用户, 1=商家, 2=骑手, 3=夜市
  • InfoUser.storeId:摊位商家关联的摊位门店ID
  • PosOrder.shId:商家ID(普通/夜市商家直接等于userId)
  • PosOrder.mdId:门店ID(摊位商家用 InfoUser.storeId 匹配)

范围控制

当用户说"只改 X"时,就只改 X——不要广泛探索、创建任务或为简单的定向修改启动 Agent。从用户提到的具体文件或区域开始,做最小的必要修改。

对于简单的格式化或显示变更(如截断小数、重命名 key、单文件修改),不要创建任务计划或启动 Agent,直接做编辑。

Behavioral guidelines to reduce common LLM coding mistakes. Merge with project-specific instructions as needed.

Tradeoff: These guidelines bias toward caution over speed. For trivial tasks, use judgment.

1. Think Before Coding

Don't assume. Don't hide confusion. Surface tradeoffs.

Before implementing:

  • State your assumptions explicitly. If uncertain, ask.
  • If multiple interpretations exist, present them - don't pick silently.
  • If a simpler approach exists, say so. Push back when warranted.
  • If something is unclear, stop. Name what's confusing. Ask.

2. Simplicity First

Minimum code that solves the problem. Nothing speculative.

  • No features beyond what was asked.
  • No abstractions for single-use code.
  • No "flexibility" or "configurability" that wasn't requested.
  • No error handling for impossible scenarios.
  • If you write 200 lines and it could be 50, rewrite it.

Ask yourself: "Would a senior engineer say this is overcomplicated?" If yes, simplify.

3. Surgical Changes

Touch only what you must. Clean up only your own mess.

When editing existing code:

  • Don't "improve" adjacent code, comments, or formatting.
  • Don't refactor things that aren't broken.
  • Match existing style, even if you'd do it differently.
  • If you notice unrelated dead code, mention it - don't delete it.

When your changes create orphans:

  • Remove imports/variables/functions that YOUR changes made unused.
  • Don't remove pre-existing dead code unless asked.

The test: Every changed line should trace directly to the user's request.

4. Goal-Driven Execution

Define success criteria. Loop until verified.

Transform tasks into verifiable goals:

  • "Add validation" → "Write tests for invalid inputs, then make them pass"
  • "Fix the bug" → "Write a test that reproduces it, then make it pass"
  • "Refactor X" → "Ensure tests pass before and after"

For multi-step tasks, state a brief plan:

1. [Step] → verify: [check]
2. [Step] → verify: [check]
3. [Step] → verify: [check]

Strong success criteria let you loop independently. Weak criteria ("make it work") require constant clarification.


These guidelines are working if: fewer unnecessary changes in diffs, fewer rewrites due to overcomplication, and clarifying questions come before implementation rather than after mistakes.
