5.1 项目需求和结构分析 需求案例搭建一个电商平台项目该平台包括用户服务、订单服务、通用工具模块等。
项目架构
用户服务负责处理用户相关的逻辑例如用户信息的管理、用户注册、登录等。订单服务负责处理订单相关的逻辑例如订单的创建、订单支付、退货、订单查看等。通用模块负责存储其他服务需要通用工具类其他服务依赖此模块。

核心点掌握目标安装maven安装、环境变量、maven配置文件修改工程创建gavp属性理解、JavaSE/EE工程创建、项目结构依赖管理依赖添加、依赖传递、版本提取、导入依赖错误解决构建管理构建过程、构建场景、构建周期等继承和聚合理解继承和聚合作用、继承语法和实践、聚合语法和实践
