## 数据库配置
本项目使用云端MySQL数据库存储用户数据、游戏记录和聊天信息。
数据库配置信息：
- 数据库类型：MySQL 8.4.3
- 服务提供商：SQLPub.com
- 数据库名称：goldminer
- 连接地址：mysql2.sqlpub.com:3307
## 安装和运行
### 快速启动（推荐）
直接双击 `run.bat` 文件即可一键启动游戏。
直接双击 `start.bat` 文件即可一键启动游戏。
这个脚本会自动：
1. 检查并安装所需的后端依赖
2. 检查并创建必要的配置文件
2. 连接到云端数据库并创建必要的表（如果不存在）
3. 同时启动后端和前端服务器
4. 自动在浏览器中打开游戏
