1.乐优商城项目搭建

前端技术：

  • 基础的HTML、CSS、JavaScript（基于ES6标准）

  • JQuery

  • Vue.js 2.0以及基于Vue的框架：Vuetify

  • 前端构建工具：WebPack

  • 前端安装包工具：NPM

  • Vue脚手架：Vue-cli

  • Vue路由：vue-router

  • ajax框架：axios

  • 基于Vue的富文本框架：quill-editor

后端技术：

  • 基础的SpringMVC、Spring 5.0和MyBatis3

  • Spring Boot 2.0.1版本

  • Spring Cloud 最新版 Finchley.RC1

  • Redis-4.0

  • RabbitMQ-3.4

  • Elasticsearch-5.6.8

  • nginx-1.10.2：

  • FastDFS - 5.0.8

  • MyCat

  • Thymeleaf

2.开发环境

  • IDE：我们使用Idea 2019 版本

  • JDK：统一使用JDK1.8

  • 项目构建：maven3.3.9以上版本即可

  • 版本控制工具：git

3.域名

我们在开发的过程中，为了保证以后的生产、测试环境统一。尽量都采用域名来访问项目。

一级域名：www.leyou.com

二级域名：manage.leyou.com , api.leyou.com

4.创建父工程

　　4.1 创建统一的父工程：leyou，用来管理依赖及其版本。

　　4.2 Ly-common：通用工具模块存放一些通用的工具类，异常处理类等

　　4.3 Ly-item：Ly-item-interface：主要是对外暴露的接口及相关实体类

　　　　　　　   Ly-item-service：所有业务逻辑及内部使用接口

　　4.4 LyEureka：注册中心，微服务之间的通信

　   4.5 LyZuul：网关。作为Zuul我们服务的统一入口

4.1：父工程的搭建
