+# 大宗商品爬虫系统
+
+## 项目概述
+
+本项目为Java语言开发的大宗商品数据爬虫与可视化分析系统，核心目标是通过一套统一框架，爬取金投网、东方财富网、同花顺财经3个不同网站的相关数据，实现海量数据采集、存储、分析与可视化。
+
+## 技术架构
+
+### 分层架构
+- **控制层（Controller）**: CrawlerController，统一调度爬虫策略
+- **模型层（Model）**: 封装业务实体（行情、指数、舆情数据）
+- **视图层（View）**: 基于JFreeChart实现可视化图表，支持HTML报告
+- **策略层（Strategy）**: 统一爬虫策略接口，各站点实现具体策略
+- **工厂层（Factory）**: 爬虫策略工厂，动态创建策略实例
+- **仓储层（Repository）**: 数据持久化操作封装
+- **命令层（Command）**: 基于Command模式实现命令管理
+- **监控层（Monitor）**: WebSocket实时数据广播
+
+### 设计模式
+- **策略模式**: 站点爬取逻辑解耦
+- **工厂模式**: 策略实例创建与管理
+- **MVC模式**: 分层架构
+- **命令模式**: 命令封装与执行
+- **仓储模式**: 数据访问层抽象
+
+### 技术栈
+- Java 1.8+
+- OkHttp3 (网络请求)
+- Jsoup (网页解析)
+- SQLite + MyBatis (数据持久化)
+- JFreeChart (可视化图表)
+- Apache POI (Excel导出)
+- Gson (JSON处理)
+- Apache PDFBox (PDF报告，中文黑体支持)
+- Java-WebSocket (实时监控)
+- SLF4J + Logback (日志)
+
+## 快速开始
+
+### 环境要求
+- JDK 1.8+
+- Maven 3.6+
+- Windows系统（PDF报告生成需要黑体字体）
+
+### 构建项目
+
+```bash
+cd commodity-crawler
+mvn clean package -DskipTests
+```
+
+### 运行爬虫
+
+```bash
+# 启动交互式菜单（推荐）
+java -jar target/commodity-crawler-1.0.0.jar
+
+# 爬取所有站点（默认30页）
+java -jar target/commodity-crawler-1.0.0.jar -s all -p 30
+
+# 爬取指定站点
+java -jar target/commodity-crawler-1.0.0.jar -s jintou -p 5
+
+# 爬取并生成分析图表
+java -jar target/commodity-crawler-1.0.0.jar -s all -p 30 -a
+
+# 爬取并导出CSV
+java -jar target/commodity-crawler-1.0.0.jar -s all -e csv
+
+# 生成PDF分析报告
+java -jar target/commodity-crawler-1.0.0.jar --report
+
+# 爬取+导出+图表+报告+监控
+java -jar target/commodity-crawler-1.0.0.jar -s all -e json -a -r -m
+```
+

+
+## 核心特性说明
+
+### MyBatis字段映射
+系统已配置`mapUnderscoreToCamelCase=true`，自动将数据库下划线命名字段映射到Java驼峰命名：
+- `index_name` → `indexName`
+- `index_value` → `indexValue`
+- `change_rate` → `changeRate`
+- `stock_name` → `stockName`
+- `stock_price` → `stockPrice`
+- `turnover_rate` → `turnoverRate`
+
+### 自定义日期类型处理器
+`DateTypeHandler`支持：
+- Unix时间戳（毫秒，13位）
+- Unix时间戳（秒，10位）
+- 日期字符串格式
+- MySQL TIMESTAMP类型
+
+### PDF报告中文支持
+- 使用黑体(simhei.ttf)字体
+- 支持中文完整显示
+- 包含8页完整报告内容
+
+### 实时监控WebSocket
+- 端口：8080
+- 推送频率：每2秒更新
+- 数据格式：JSON
+- 监控页面自动连接
+
+### 完整离线支持
+系统支持**完整离线运行**，所有核心功能均不依赖网络：
+- ✅ 数据爬取（使用模拟数据生成）
+- ✅ 数据存储（SQLite本地数据库）
+- ✅ 数据导出（Excel/CSV/JSON本地文件）
+- ✅ 图表生成（JFreeChart本地生成）
+- ✅ PDF报告（本地字体和PDFBox生成）
+- ✅ 实时监控页面（ECharts库本地化）
+
+## 扩展说明
+
+### 新增爬虫站点
+1. 实现 `CrawlStrategy` 接口
+2. 在 `CrawlStrategyFactory` 中添加分支
+3. 无需修改原有代码
+
+### 新增导出格式
+1. 实现 `DataExporter` 接口
+2. 在 `DataExporterFactory` 中注册
+3. 自动集成到导出命令
+
+### 新增分析维度
+1. 在 `ChartGenerator` 中添加新方法
+2. 实现图表生成逻辑
+
+## 输出文件说明
+
+| 类型 | 目录 | 说明 |
+|------|------|------|
+| 图表 | `./output/charts/` | 价格趋势、波动率、相关性、舆情分析图 |
+| 数据 | `./output/excel/` | Excel、CSV、JSON格式导出文件 |
+| 报告 | `./output/report/` | 中文PDF分析报告 |
+| 数据库 | `./data/` | SQLite数据库文件 |
+| 日志 | `./logs/` | 系统运行日志 |
+
+## 注意事项
+
+1. 请确保遵守目标网站的 robots.txt 协议
+2. 合理设置请求间隔，避免触发反爬机制
+3. 首次运行会自动创建SQLite数据库文件
+4. PDF报告需要Windows系统黑体字体支持
+5. 建议定期清理输出目录中的历史文件
+6. 系统支持完整离线运行，所有核心功能均可在断网环境下正常使用
