请求路径是单向分层：用户端 → Nginx → Gateway → 对应业务域。六个 Java 域各自持有 api 契约和 server 实现，靠 Nacos 注册发现；MySQL 按域拆成六个库。AI 生成在 Python 服务，Java ai 域负责额度、会话和落库，普通社区功能不绑定具体模型。

项目结构

目录	负责什么
forum-vue	用户端页面、编辑器、社区互动与看板娘界面
java-cloud-standalone	Gateway + 六域 api/server + 公共 common
ai-server	发帖检查、摘要、写作、生图、站内检索与看板娘
nginx	网站入口、Compose、打包和发布脚本
live2d	看板娘模型资源
migrate-online-db.sh	旧单库 forum_db 拆到六域库的迁移脚本

六域职责

域	进程	数据库	主要职责
auth	forum-auth	forum_auth_db	登录注册、账号资料、权限快照
content	forum-content	forum_content_db	帖子、板块、标签、评论、弹幕、推荐
im	forum-im	forum_im_db	私信、群聊、通知、语音信令
game	forum-game	forum_game_db	大厅、房间、对局、排行
economy	forum-economy	forum_economy_db	积分、签到、抽奖、会员
ai	forum-ai	forum_ai_db	AI 额度、会话、漂流瓶、看板娘业务落库

跨域只依赖对方的 xxx-api，通过本地 Feign 客户端调用；不共享 Entity、Mapper、Service 实现。

AI 模块

AI 模块采用"统一入口、模块化处理"的方式。Java 后端不直接调用某一张图或某个模型，而是把请求交给 AI 服务入口；AI 服务按 taskType + intent + version 路由到已注册模块。当前的八个 Python 模块目录承载内容审核、摘要、创作、生图、游戏、搜索、RAG、推荐和看板娘九类 Gateway 能力；Java 始终负责权限、额度、持久化与最终业务状态。

本地启动

准备 Java 17、Python 3.11、Node.js、Docker Desktop。中间件（含与线上同镜像的 Nacos）由开发 Compose 拉起。

# 中间件（开发 Compose：Nacos / MySQL / Redis / RabbitMQ / PostgreSQL / FFmpeg）
cd nginx
docker compose -f docker-compose.dev.yaml up -d
# IDEA 连接 Nacos 客户端：127.0.0.1:8848；浏览器控制台：http://127.0.0.1:8080/index.html
# （勿再启动仓库内本机独立 Nacos，避免端口冲突）

# 用户端
cd ..\forum-vue\front
npm install
npm run dev

# Java 微服务（IDEA 推荐按模块启动，或根目录 reactor 打包后分别启动）
cd ..\..\java-cloud-standalone
mvn -DskipTests package
# 依次启动：gateway、auth、content、im、game、economy、ai

# AI 服务
cd ..\ai-server
python main.py

若本地仍是旧的单库 forum_db，可先执行：

bash migrate-online-db.sh migrate-data

本地构建和 Docker 构建会通过本机 7897 代理访问外部依赖。密钥和环境差异只放在环境变量或本地配置中，不放入仓库。

分工 ：nginx/.env 只给 Docker Compose / up.sh 部署用；本地 IDEA 启动的 Java 不再 读取该文件，只使用系统环境变量与各模块 application.yml 默认值。

环境变量说明

参考 nginx/.env.example（部署用），主要配置项：

变量	说明
JWT_SECRET	JWT 签名密钥，生产必须替换
PII_CRYPTO_SECRET	手机号等敏感字段对称加密密钥
MYSQL_ROOT_PASSWORD	MySQL root 密码
FORUM_*_DB_USERNAME / FORUM_*_DB_PASSWORD	六个业务域数据库账号
NACOS_ADDR	Nacos 地址，生产默认 nacos:8848
REDIS_PASSWORD	Redis 认证密码
RABBITMQ_USER / RABBITMQ_PASSWORD / RABBITMQ_VHOST	MQ 账号与虚拟主机
DASHSCOPE_API_KEY	通义大模型 API Key
TAVILY_API_KEY	看板娘联网搜索 Key
HUANAPI_IMAGE_KEY	图片生成服务 Key
ALIYUN_ACCESS_KEY_ID/SECRET	阿里云 OSS / 短信公共凭据
FORUM_MASCOT_INTERNAL_KEY	Java ↔ Python 内部鉴权密钥，两侧须一致
FORUM_VOICE_TURN_*	语音通话用的 TURN 服务器地址和凭据

在 nginx 目录执行：

.\scripts\make-package.ps1

默认只显示简洁的构建结果。需要查看镜像构建详情时，再使用：

.\scripts\make-package.ps1 -ShowBuildDetails

完整发布包会生成在 nginx\package\。上传前可校验：

.\scripts\verify-package.ps1

发布包以六个 server 模块各自的 src/main/resources/db/create.sql 作为独立数据库初始化基线。已有旧单库 forum_db 的环境，上线前用包内 migrate-online-db.sh migrate-data 建六域结构并搬迁数据，默认保留 forum_db。旧会话清理默认关闭，只有明确把脚本中的开关改为 1 才会执行清理。

核心设计思路

权限边界放在各 Java 业务域的 Service 层。前端的登录拦截只是减少无效请求；跨域调用通过 auth-api 等契约获取身份快照，AI 服务也只接受附带内部密钥的请求。

帖子有一套严格的状态流转：草稿 → 待审核 → 已发布，每一步只能由 Java Service 推进。审核期间字段锁定，前端拿不到直接改状态的入口。每次提交审核都会生成一个任务 ID 写入 article.audit_task_id，和 AI 侧 LangGraph 的 thread_id 对应，审核过程可以完整追溯。

AI 服务只管生成，不管写入。审核结论、摘要、推荐特征都由模型给出，但落库的动作始终在 Java 完成。这样换模型或 AI 服务临时挂掉，不会影响发帖、聊天这些核心功能。

消息的逻辑是先存后推。WebSocket 断线重连后，未读内容从数据库补全，不依赖连接状态。私信、群聊、语音邀请和系统通知走同一套流程，差别只在消息类型字段。

游戏的实时状态放在内存里，结束后再写库。对局中的每一步通过 WebSocket 广播给房间成员，游戏结束才把战绩和回放写进数据库，不做高频持久化。

站内搜索优先走向量召回，没命中再退回关键词排序。搜索模块只返回候选 ID 和相关分数，权限过滤和分页由 Java 完成，搜索结果不会泄露无权查看的内容。

Gateway 与六个 Java 业务容器共用 forum-backend 镜像，靠不同 jar 入口区分进程。ffmpeg 负责视频转码，经内部密钥与 Java / AI 通信。

开发约定

• 内容、权限和数据由对应业务域的 Java 服务决定，页面只负责展示和提交操作。
• AI 只通过统一入口接入，页面不直接调用具体模型。
• 新的数据库变更只追加新脚本，不修改已经执行过的历史脚本。
• 密码、密钥、验证码或本地环境配置不提交仓库。
