=== 基本信息 ===
版本号: ${project.version}
生成时间: ${maven.build.timestamp}
开发者: Coproject 团队
=== 系统要求 ===
- 操作系统: Windows 7/10/11
- Java版本: Java 17 或更高版本
- 内存: 至少 2GB 可用内存
=== 启动方法 ===
推荐使用以下方式启动：
1. 双击运行 run.bat (推荐，有错误提示)
2. 双击 start.bat (简洁版)
3. 双击 测试运行.bat (先检查环境再启动)
=== 功能特点 ===
✓ 小学数学题目生成
✓ 初中数学题目生成（含平方根号）
✓ 高中数学题目生成（含三角函数）
✓ 选择题答题系统
✓ 邮件发送验证码功能
✓ 试卷PDF导出功能
=== 目录说明 ===
math-learning-0.1.2.jar - 主程序文件
lib/ - 程序依赖库（请勿删除或移动）
data/ - 数据存储目录
├── smtp.env - 邮箱配置文件
└── papers/ - 试卷存储目录
run.bat - Windows启动脚本(详细版)
start.bat - Windows启动脚本(简洁版)
测试运行.bat - 环境测试脚本
README.md - 项目说明文档
=== 配置说明 ===
1. 首次运行会自动创建配置文件
2. 邮箱配置请参考 smtp.env.example
3. 生成的试卷保存在 data/papers/ 目录
=== 常见问题 ===
Q: 启动时提示"缺少JavaFX运行时组件"
A: 请确保使用 .bat 文件启动，不要直接双击JAR文件
Q: 邮件发送失败
A: 请检查 data/smtp.env 中的邮箱配置
Q: 程序无法启动
A: 请先运行"测试运行.bat"检查环境
=== 技术支持 ===
如有问题请联系开发团队。
注意：请保持所有文件在同一个目录下，不要单独移动文件！
