+# 凯迪 ERP + OA 一体化平台
+
+凯迪 ERP + OA 是面向企业内部运营的综合业务平台，覆盖组织协同、审批、合同、采购、库存、财务、人力、项目、制造、运营、档案、审计和系统管理等工作域。前端采用 Vue 3 + TypeScript + Element Plus，后端采用 Spring Boot 3.2 + Spring Data JPA。
+
+> 生产部署固定使用 PostgreSQL 15 或更高版本，不使用 Docker。源码目录保留的 SQLite 配置只用于本地开发和测试；正式 Release JAR 会排除 SQLite 驱动和社区方言。
+
+## 项目现状
+
+- 业务范围覆盖 29 个机构/部门，包含约 700 个 Vue 业务页面和大规模 REST/JPA 模型。
+- 当前有效后端位于 `oa-backend/`。
+- 当前有效前端位于 `ofbiz-framework/plugins/modern-ui/app/`；其上层旧 OFBiz 运行框架已经弃用。
+- 前端构建产物直接写入后端 `src/main/resources/static/`，由同一个 Spring Boot JAR 提供页面与 `/api/oa/*` API。
+- 已实现非 Docker 一键安装、PostgreSQL Flyway 迁移、独立网页安装向导、Gitea Release 更新、Ed25519/SHA-256 校验、服务重启、健康检查和自动回滚。
+- 业务功能和外部系统接入仍需按项目需求验收；技术部署链路通过不等于可以跳过生产安全、备份和数据迁移评审。
+
+## 两种运行模式
+
+| 模式 | 数据库 | 用途 | 关键约束 |
+|---|---|---|---|
+| 源码开发 | SQLite 或 PostgreSQL | 本机开发、界面调试、自动化测试 | SQLite 仅为零配置开发选项，不代表在线环境 |
+| 正式安装 | PostgreSQL 15+ | 服务器部署、在线更新 | 使用签名 Release、systemd/launchd，生产 JAR 不含 SQLite |
+

+
+## 本地构建
+
+克隆仓库并进入开发分支：
+
+```bash
+git clone git@38.76.196.225:awaioi/ERP.git
+cd ERP
+git switch dev
+git config core.hooksPath .githooks
+```
+
+### 环境要求
+
+- Java 17 或更高版本
+- Node.js 和 npm
+- Python 3、curl、lsof
+- 使用公网预览时需要已登录并配置好的 ngrok 3
+- PostgreSQL 模式需要 PostgreSQL 15+ 以及可连接的数据库账号
+
+### 1. 构建前端
+
+```bash
+cd ofbiz-framework/plugins/modern-ui/app
+npm ci
+NODE_OPTIONS=--max-old-space-size=8192 npm run build
+```
+
+Vite 会清空并重新生成 `oa-backend/src/main/resources/static/`。修改前端后必须先执行前端构建，再执行 `bootJar`，否则 JAR 中仍是旧页面。
+
+### 2. 构建后端
+
+开发构建保留 SQLite 运行库：
+
+```bash
+cd oa-backend
+./gradlew test
+./gradlew bootJar
+```
+
+PostgreSQL-only 正式构建：
+
+```bash
+cd oa-backend
+./gradlew clean bootJar -PreleaseVersion=0.2.0 -PproductionBuild=true
+```
+
+正式 JAR 必须包含 PostgreSQL 驱动，并且不得包含 `sqlite-jdbc` 或 `hibernate-community-dialects`。
+
+## 一键启动本地预览
+
+根目录的 `run.command` 会检查环境、启动或复用 ERP 后端、启动或复用固定 ngrok 隧道、验证本地登录和公网页面，然后打开浏览器。它不会安装 PostgreSQL、构建前端或生成 JAR。
+
+```bash
+chmod +x run.command
+./run.command
+```
+
+macOS 也可以在 Finder 中双击 `run.command`。终端保持运行用于监控服务，按 `Ctrl+C` 只会停止本次启动器自己创建的进程，不会批量终止其他 Java 进程。
+
+常用覆盖项：
+
+| 环境变量 | 默认值 | 说明 |
+|---|---|---|
+| `ERP_RUN_BACKEND_PORT` | `8091` | 本地 Spring Boot 端口 |
+| `ERP_RUN_JAR_PATH` | 最新的 `oa-backend-*.jar` | 指定要运行的 JAR |
+| `ERP_RUN_PROFILE` | 当前环境的 Spring profile | 正式环境设为 `postgres` |
+| `ERP_RUN_CONFIG_FILE` | 空 | 读取安装器生成的 `erp.env` |
+| `ERP_RUN_PUBLIC_URL` | 固定 ngrok 域名 | 公网预览地址 |
+| `ERP_RUN_NGROK_API_PORT` | `4040` | ngrok 本地管理端口 |
+| `ERP_RUN_NO_OPEN` | `0` | 设为 `1` 时不自动打开浏览器 |
+
+直接以 PostgreSQL profile 运行源码构建时：
+
+```bash
+export SPRING_PROFILES_ACTIVE=postgres
+export OA_DB_URL='jdbc:postgresql://127.0.0.1:5432/kaidi_erp?sslmode=disable'
+export OA_DB_USERNAME='kaidi_erp'
+export OA_DB_PASSWORD='replace-with-a-strong-password'
+./run.command
+```
+
+默认本地地址为 `http://127.0.0.1:8091`。开发预览固定域名为：
+
+```text
+https://resonant-elated-launder.ngrok-free.dev/
+```
+
+演示环境初始账号为 `admin / 123456`。任何共享或生产环境都必须立即更换默认密码，并限制公网访问。
+
+## 非 Docker 正式安装
+
+安装器支持 64 位 Linux `amd64/arm64` 和 macOS `arm64/amd64`。Linux 安装需要 root；macOS 不应使用 sudo 启动 LaunchAgent。正式安装前必须已有包含下列四个资产的 Gitea Release：
+
+- `kaidi-erp-<version>.tar.gz`
+- `kaidi-erp-installer-<version>.jar`
+- `SHA256SUMS`
+- `SHA256SUMS.sig`
+
+### Linux 一键安装
+
+生产环境应先为 Gitea 配置 HTTPS：
+
+```bash
+curl -fsSL https://git.example.com/awaioi/ERP/raw/branch/main/install.sh \
+  | sudo -E bash -s -- \
+      --gitea-url https://git.example.com \
+      --repository awaioi/ERP
+```
+
+命令行只做环境准备：优先使用已有的 Java 17+，缺少时通过当前系统的 `apt-get`、`dnf`、`yum`、`zypper` 或 Homebrew 安装 Java、curl、tar、Python 3 和 OpenSSL 3，然后下载并启动独立安装器。数据库信息不在命令行输入。
+
+Linux 生产服务要求主机使用 systemd；没有 systemd 的容器、WSL 或精简系统只能显式使用 `--no-service` 做开发验收，在线更新也会保持关闭。
+
+安装器启动后会输出带一次性令牌的局域网地址，例如：
+
+```text
+Setup URL: http://192.168.1.20:8091/?token=<one-time-token>
+```
+
+首次打开该地址进入网页向导，依次完成环境检查、PostgreSQL 地址/端口/库名/账号/密码/SSL 测试、管理员账号/姓名/密码设置、数据库迁移和初始化。项目当前没有 Redis 依赖，因此向导不会显示 Redis 配置项。正式服务真实健康检查通过后，启动器才会原子写入安装锁并物理删除 `installer/` 和 `install.pending`。
+
+PostgreSQL 必须使用专用空数据库，网页中填写的账号必须是该数据库的所有者。该约束保证账号拥有 `public` schema 建表权限，并能持有安装器创建的 `pg_trgm` 扩展；只授予 `CONNECT` 权限不足以完成迁移。
+
+### macOS
+
+macOS 需要 Homebrew，并使用已有 PostgreSQL：
+
+```bash
+curl -fsSL https://git.example.com/awaioi/ERP/raw/branch/main/install.sh \
+  | bash -s -- \
+      --gitea-url https://git.example.com \
+      --repository awaioi/ERP
+```
+
+### 当前 HTTP 测试服务器
+
+当前 Gitea 地址 `http://38.76.196.225:10099` 只允许用于开发验收：
+
+```bash
+(
+  set -e
+  tmp="$(mktemp)"
+  trap 'rm -f -- "$tmp"' EXIT
+  curl -fsSL http://38.76.196.225:10099/awaioi/ERP/raw/tag/v0.3.1/install.sh -o "$tmp"
+  printf '%s  %s\n' '89a3c45e76f500c9475cb596ea29e3518bfafdc59f36dd3c7b316ed3cdd0448c' "$tmp" | sha256sum -c -
+  sudo -E bash "$tmp" \
+    --gitea-url http://38.76.196.225:10099 \
+    --repository awaioi/ERP \
+    --allow-insecure
+)
+```
+
+只有 `v0.3.1` Release 发布后这条命令才可下载安装包。固定 tag 和 SHA-256 只用于保护当前 HTTP 引导脚本不被传输途中篡改；Release 资产仍会继续执行 Ed25519 和 SHA-256 双重校验。HTTP 会暴露请求、Release 元数据和可能使用的访问令牌，不得作为生产方案。
+
+### 完整卸载后重装
+
+以下命令具有破坏性：它会先停止服务，使用现有配置中的 ERP 数据库账号删除并重建目标数据库的 `public` schema，然后删除 systemd unit、程序、配置、状态和日志。脚本只允许数据库所有者执行 schema 清理，并拒绝 `postgres`、`template0`、`template1` 和危险文件路径。
+
+```bash
+(
+  set -e
+  tmp="$(mktemp)"
+  trap 'rm -f -- "$tmp"' EXIT
+  curl -fsSL http://38.76.196.225:10099/awaioi/ERP/raw/tag/v0.3.1/uninstall.sh -o "$tmp"
+  printf '%s  %s\n' '98c56fed2fd4d01874e4ab5a1a4f3ec42ec3e29b315ffd87385a95488d587546' "$tmp" | sha256sum -c -
+  sudo -E bash "$tmp" --purge-database --yes
+)
+```
+
+卸载器会先核对安装配置、路径和 systemd 停止状态，再清理数据库和文件。卸载成功后，再执行上面的 Linux 一键安装命令。不要对包含其他系统数据的共享数据库运行此命令。
+
+### 正式安装目录
+
+Linux 默认路径：
+
+| 内容 | 路径 |
+|---|---|
+| 程序和版本目录 | `/opt/kaidi-erp` |
+| 环境配置 | `/etc/kaidi-erp/erp.env` |
+| 更新状态 | `/var/lib/kaidi-erp/update-state.json` |
+| 安装状态 | `/var/lib/kaidi-erp/install.pending`、`/var/lib/kaidi-erp/install.lock` |
+| 首次安装器 | `/opt/kaidi-erp/installer/`（健康后自动删除） |
+| systemd 服务 | `kaidi-erp.service` |
+
+使用 `--no-service` 只用于开发验收：启动器会在当前用户下运行，但默认设置 `OA_UPDATE_ENABLED=false`。生产环境应使用 systemd/launchd，让在线更新可以在 Java 进程退出后自动拉起新版本。
+
+### HTTPS 反向代理
+
+正式服务监听 `8090`。Nginx、宝塔、Caddy 或 CDN 终止 HTTPS 后，必须把公网协议和主机转发给 Spring Boot；否则浏览器的同源 API 请求会被误判为跨域，并收到纯文本 `403 Invalid CORS request`，前端表现为“响应非 JSON (HTTP 403)”。Nginx 的代理位置至少包含：
+
+```nginx
+location / {
+    proxy_pass http://127.0.0.1:8090;
+    proxy_http_version 1.1;
+    proxy_set_header Host $host;
+    proxy_set_header X-Forwarded-Host $host;
+    proxy_set_header X-Forwarded-Proto $scheme;
+    proxy_set_header X-Forwarded-Port $server_port;
+    proxy_set_header X-Real-IP $remote_addr;
+    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+}
+```
+
+如果 Nginx 前面还有 Cloudflare 等上游代理，`X-Forwarded-Proto` 必须保留浏览器实际使用的 `https`，不能被内层 HTTP 链路覆盖。前端与 `/api/oa/*` 推荐使用同一个公网域名；不要在 Nginx 中附加 `Access-Control-Allow-Origin *`。
+
+## 在线更新与回滚
+
+管理员登录后进入：
+
+```text
+应用定制平台 -> 系统更新
+```
+
+对应前端路由为 `/appdev/update`，后端 API 为 `/api/oa/system-update/*`。更新过程如下：
+
+1. 从 Gitea 读取 stable channel 的最新 Release。
+2. 下载归档、`SHA256SUMS` 和 Ed25519 签名（Release 里的独立安装器资产只用于首次安装）。
+3. 先验证签名和 SHA-256，再拒绝路径穿越、绝对路径、符号链接、硬链接和结构不完整的归档。
+4. 校验 `manifest.json` 中的版本、`database=postgresql` 和 `rollbackCompatible=true`。
+5. 可选执行 `pg_dump`，将新版本写入独立目录。
+6. 原子切换 `current` 符号链接，并停止旧 Java 进程。
+7. systemd/launchd 拉起新版本，更新助手等待新的 PID 和 `/api/oa/health`。
+8. 新版本不健康时切回上一链接，终止故障进程并再次验证旧版本健康状态。
+
+同一安装目录使用操作系统文件锁，不能并发执行两个更新任务。也可以手工触发：
+
+```bash
+/opt/kaidi-erp/current/bin/erp-update install 0.2.0
+```
+
+应用回滚不等于数据库回滚。包含不可逆 Flyway 迁移的版本必须先保证旧应用仍兼容新结构，并建议在安装配置中启用：
+
+```bash
+ERP_UPDATE_BACKUP_MODE=pg_dump
+```
+
+更新助手不会自动覆盖生产数据库。需要恢复数据库时，应由管理员确认后使用 `pg_restore`。
+
+## Gitea Release 发布
+
+推送 `v*` tag 会触发 `.gitea/workflows/release.yml`。流水线会先执行 shell、后端和独立安装器测试，再构建前端、生成 PostgreSQL-only JAR、打包、签名，并创建或更新对应 Gitea Release。
+
+### Actions 前置配置
+
+Gitea 1.27 仓库需要启用 Actions，并配置带 `ubuntu-latest` 标签的在线 Runner。Runner 必须提供：
+
+- Java 17+
+- Node.js 和 npm
+- Python 3
+- curl、tar
+- OpenSSL 3，且支持 Ed25519
+
+流水线使用 Gitea 内置短期 `GITEA_TOKEN`，权限限定为代码只读、当前仓库 Release 可写。仓库设置只需添加：
+
+- Secret `RELEASE_PRIVATE_KEY_B64`
+- 当前纯 HTTP 测试服务器额外添加 Variable `ERP_RELEASE_ALLOW_INSECURE_HTTP=1`（Gitea 禁止变量名以保留前缀 `GITEA_` 或 `GITHUB_` 开头）
+
+签名私钥不得提交到 Git。生成 Secret 值：
+
+```bash
+base64 < ~/.config/kaidi-erp/release-signing-key.pem | tr -d '\n'
+```
+
+发布稳定版本：
+
+```bash
+git switch main
+git pull --ff-only origin main
+git tag -a v0.2.0 -m 'Kaidi ERP v0.2.0'
+git push origin v0.2.0
+```
+
+发布完成后必须确认 Release 页面存在四个资产，并使用仓库中的 `distribution/release-public-key.pem` 验证签名。私钥与该公钥不匹配时打包脚本会直接失败。
+
+本地手工生成签名资产：
+
+```bash
+ERP_RELEASE_PRIVATE_KEY_FILE="$HOME/.config/kaidi-erp/release-signing-key.pem" \
+  bash scripts/package-release.sh 0.2.0
+```
+
+## 配置参考
+
+| 环境变量 | 说明 | 默认值 |
+|---|---|---|
+| `SPRING_PROFILES_ACTIVE` | 正式环境必须为 `postgres` | 源码默认 profile |
+| `OA_DB_URL` | JDBC PostgreSQL URL | 正式环境必填 |
+| `OA_DB_USERNAME` | PostgreSQL 用户 | 正式环境必填 |
+| `OA_DB_PASSWORD` | PostgreSQL 密码 | 正式环境必填 |
+| `OA_DB_POOL_MAX` | 最大连接池 | `20` |
+| `OA_DB_POOL_MIN` | 最小空闲连接 | `2` |
+| `OA_UPDATE_ENABLED` | 启用管理后台在线更新 | 安装服务时为 `true` |
+| `OA_UPDATE_GITEA_BASE_URL` | Gitea 外部地址 | 正式安装时写入 |
+| `OA_UPDATE_REPOSITORY` | Release 仓库 | `awaioi/ERP` |
+| `OA_UPDATE_CHANNEL` | 更新通道 | `stable` |
+| `OA_UPDATE_TOKEN` | 私有仓库下载令牌 | 空；公开仓库不需要 |
+| `OA_UPDATE_ALLOW_INSECURE_HTTP` | 允许 HTTP 更新地址 | `false` |
+| `OA_SEED_DEMO` | 是否生成演示数据 | 正式安装为 `false` |
+| `ERP_UPDATE_BACKUP_MODE` | 更新前数据库备份 | `none`，可设 `pg_dump` |
+| `ERP_UPDATE_HEALTH_TIMEOUT_SECONDS` | 新旧版本健康检查超时 | `120` |
+| `ERP_UPDATE_HEALTH_POLL_SECONDS` | 健康轮询间隔 | `2` |
+
+## 测试与验收
+
+### 后端
+
+```bash
+cd oa-backend
+./gradlew test
+```
+
+### 前端类型检查与构建
+
+```bash
+cd ofbiz-framework/plugins/modern-ui/app
+npm ci
+NODE_OPTIONS=--max-old-space-size=8192 npm run build
+```
+
+### 启动器与发布脚本
+
+```bash
+bash tests/run-command.test.sh
+bash tests/release-scripts.test.sh
+```
+
+### 已运行服务的 OA 冒烟和集成测试
+
+```bash
+OA=http://127.0.0.1:8091 bash oa-smoke.sh
+OA=http://127.0.0.1:8091 bash oa-itest.sh
+```
+
+测试脚本会创建业务测试数据，应使用测试数据库，不要直接对生产数据库运行写入型集成测试。
+
+## 安全与运维注意事项
+
+- 正式 Gitea、安装和更新流量必须使用 HTTPS；`--allow-insecure` 仅限隔离测试环境。
+- `RELEASE_PRIVATE_KEY_B64` 和 PostgreSQL 密码不得写入 Git、日志或聊天记录。
+- 新增返回金额、个人信息或机密汇总的 API 时，必须复核 `AuthInterceptor` 的敏感读取权限前缀。
+- 金额字段和计算统一使用 `BigDecimal`，禁止使用 `double` 处理货币。
+- 不要使用 `pkill java` 或 `killall java`；只停止明确属于本项目的 PID。
+- 修改前端后始终先执行前端构建，再打包后端。
+- 每次包含数据库结构变更的 Release 都必须新增 Flyway 迁移并做新库首次迁移、旧库升级和回滚兼容性验证。
+- 默认演示账号只能用于开发环境，生产环境需要更换密码并实施最小权限、备份、监控和审计策略。
+
+## 常见问题
+
+### 安装器提示没有 Release
+
+Gitea 仓库尚未发布首个可安装版本，或 Release 缺少四个必需资产。先检查 `/api/v1/repos/awaioi/ERP/releases/latest` 和 Release 页面。
+
+### 如何填写数据库
+
+数据库连接信息只在首次网页向导填写。安装器会执行 `SELECT 1`、检查 PostgreSQL 15+ 并创建/验证 `pg_trgm`，错误凭据不会启动正式应用，也不会把密码写入响应或日志。数据库中已经有业务用户时，安装器会拒绝接管。
+
+### PostgreSQL profile 启动失败
+
+确认 `SPRING_PROFILES_ACTIVE=postgres`，并检查 `OA_DB_URL`、`OA_DB_USERNAME`、`OA_DB_PASSWORD`。正式 profile 会执行 Flyway，再使用 Hibernate `ddl-auto=validate` 校验实体与数据库结构。
+
+### `run.command` 提示端口被占用
+
+启动器只会复用能够通过项目健康检查的监听进程。其他程序占用端口时不会被自动终止；请停止对应程序或设置新的 `ERP_RUN_BACKEND_PORT`。
+
+### ngrok 无法启动
+
+运行 `ngrok config check` 确认配置有效，并检查固定域名是否属于当前 ngrok 账号。可以通过 `ERP_RUN_NGROK_BIN`、`ERP_RUN_NGROK_CONFIG` 和 `ERP_RUN_NGROK_API_PORT` 覆盖路径与端口。
+
+### 反向代理后提示“响应非 JSON (HTTP 403)”
+
+应用自身的 401/403 权限错误始终是 JSON。该提示表示 Nginx、WAF 或 Spring CORS 层提前返回了纯文本/HTML。先确认代理目标为 `http://127.0.0.1:8090`，再按“HTTPS 反向代理”一节补齐 `Host` 和 `X-Forwarded-*` 请求头；响应正文为 `Invalid CORS request` 时即可确认是协议/主机转发不完整。
+
+### 签名验证失败
+
+不要跳过验证。确认 Release 的四个资产来自同一次构建、`SHA256SUMS` 未被改写、签名私钥与 `distribution/release-public-key.pem` 匹配。
+
+## Git 协作
+
+- `dev` 是日常开发分支。
+- `main` 只接收已经通过构建、测试、启动和冒烟验证的稳定提交。
+- 新环境执行 `git config core.hooksPath .githooks` 启用仓库 hooks。
+- 不要在脏工作区执行破坏性 reset；先确认哪些修改属于正在进行的开发。
