 # SVN Manager
 
-SVN管理工具 - 多项目管理界面
-
-## 项目简介
-
-基于 JavaFX 开发的 SVN 管理工具，提供图形化界面进行 SVN 仓库的日常操作。
+SVN 管理工具 - 多项目管理界面
 
 ## 技术栈
 
-- **Java**: 11+
-- **JavaFX**: 17.0.2
-- **Maven**: 构建工具
-- **Jackson**: JSON 解析
-- **Logback**: 日志管理
-
-## 功能特性
-
-### 1. 仓库管理
-- Checkout 检出仓库
-- Update 更新仓库
-- Commit 提交修改
-
-### 2. 文件操作
-- Add 添加文件
-- Delete 删除文件
-- Revert 回退文件
-
-### 3. 版本查看
-- Status 查看状态
-- Log 查看日志
-- Diff 查看差异
-- Info 查看信息
-
-### 4. 分支管理
-- Create Branch 创建分支
-- Switch 切换分支
-- Merge 合并分支
+- **前端**: Vue 3 + Vite + Pinia + Axios（IDEA 风格深色主题）
+- **后端**: Java 17 + Spring Boot 3，REST API，本地调用 `svn` CLI
+- **配置**: 项目列表存储在 `~/.svn-manager/projects.json`

-## 构建与运行
+## 运行方式
 
 ### 前置要求
-- JDK 11 或更高版本
-- Maven 3.6+
-- SVN 客户端已安装并配置在系统 PATH 中
 
-### 编译项目
+- JDK 17+
+- Node.js 18+
+- 系统已安装 `svn` 并已在 PATH 中
+
+### 1. 启动后端
+
 ```bash
-mvn clean compile
+cd backend
+mvn spring-boot:run
 ```
 
-### 运行项目
+后端默认端口：`8080`，API 前缀：`/api`。
+
+### 2. 启动前端
+
 ```bash
-mvn javafx:run
+cd frontend
+npm install
+npm run dev
 ```
 
-### 打包项目
-```bash
-mvn clean package
-```
+浏览器访问 Vite 提供的地址（如 `http://localhost:5173`）。开发环境下 Vite 会将 `/api` 代理到 `http://localhost:8080`。
 
-## 开发说明
+### 3. 生产构建
 
-项目采用 MVC 架构模式：
-- **Controller**: 处理 UI 交互逻辑
-- **Service**: 封装 SVN 命令调用
-- **Model**: 解析 SVN 输出数据
-- **Util**: 提供通用工具方法
+- 后端：`cd backend && mvn package`，运行 `java -jar target/svn-manager-backend-1.0.0.jar`
+- 前端：`cd frontend && npm run build`，将 `dist/` 部署到任意静态服务器，并配置 API 代理或同域部署
+
+## 功能说明
+
+- **项目列表**：左侧栏展示已配置项目，点击切换当前项目
+- **添加项目**：填写本地工作副本路径（及可选 SVN 地址、账号密码）保存到 `~/.svn-manager/projects.json`
+- **文件树**：选中项目后自动拉取 `svn status` 并展示树形结构，支持 SVN 状态徽章（M/A/D/C/?）
+- **工具栏**：刷新状态、更新、提交、日志、差异；提交/日志/差异通过弹窗完成
