Java 程序设计课大作业——外卖订餐管理系统。

系统区分顾客和商家两种角色，提供不同的操作界面和功能。

完善的购物流程:

• 顾客端:
  • 注册与登录
  • 菜品浏览与瀑布流展示，关键词搜索
  • 购物车管理 (添加商品、修改数量、删除商品、实时总价计算)
  • 便捷下单 (可直接从菜品列表下单或通过购物车结算)
  • 订单历史查看与状态跟踪
  • 个人信息维护 (修改联系方式、地址、登录密码，含输入验证)
• 商家端:
  • 商品管理 (发布新菜品、编辑现有菜品信息、设置菜品上下架状态)
  • 订单管理 (查看顾客订单、更新订单状态)
  • 商家信息维护

技术栈

• 核心语言: Java
• 用户界面: Java Swing
• ORM框架: Hibernate
• 数据库: MySQL 5.7+
• 项目管理与构建: Apache Maven
• 版本控制: Git

持久层

使用 Hibernate 连接 MySQL 数据库。

数据库 SQL 代码，可以直接用：

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;

使用前请在 MySQL 中创建一个新的数据库，例如 takeout。

随后修改 Hibernate 配置文件 src/main/resources/hibernate.cfg.xml 中的数据库连接信息，以匹配自己的 MySQL 设置：

<property name="connection.url">jdbc:mysql://localhost:3306/takeout_db?useSSL=false&serverTimezone=UTC</property>
<property name="connection.username">你的MySQL用户名</property>
<property name="connection.password">你的MySQL密码</property>

UI

使用 Swing 框架，有一些自定义的组件和布局。

逻辑层

一些基础的 CURD。
