架构设计与环境搭建

项目架构

项目介绍

教育 PC 站是提供给学员观看技术视频的网站。

学员使用手机号注册登录后，可以选择适合自己的课程，并观看课程视频，当然，有免费的课程，也有 VIP 专属课程。

技术选型

前端技术选型

  • Vue.js - 是一套用于构建用户界面的渐进式 JavaScript 框架
  • ElementUI 库 - 是饿了么前端出品的基于 Vue.js 的后台组件库，方便程序员进行页面快速布局和构建
  • node.js - 简单的说 Node.js 就是运行在服务端的 JavaScript 运行环境
  • Axios - 对 Ajax 的封装, 简单来说就是 Ajax 技术实现了局部数据的刷新，AXIOS 实现了对 Ajax 的封装

后端技术选型

  • Web 层借助 SpringMVC 接收请求，进行视图跳转
  • Service 层借助 Spring 进行 IOC、AOP、及事务管理
  • Dao 层 借助 MyBatis 进行数据库交互
  • EasyCode 插件 IDEA 快速生成实体类的插件
  • Zookeeper 服务注册与服务发现
  • Dubbo 分布式框架，远程 RPC 调用
  • Redis 内存数据库，缓存
  • Lombok 消除实体类中冗余的 get 和 set
  • SpringSocial 简单理解就是和第三方应用打交道，微信登录用

项目开发环境

开发工具

  • 后端 - IDEA 2019
  • 前端 - VS code
  • 数据库客户端工具 - SQLYog

开发环境

  • JDK 11
  • Maven 3.6.3
  • MySQL 5.7
  • Zookeeper 3.6.0
  • Dubbo 2.5.7
  • Redis 5.0.4

开发后端服务接口

采用前后端分离的开发模式，先开发后端服务接口，测试成功，再开发前端 Vue.js 界面，最后进行前后端联调，项目上线。

项目结构与命名

单一架构：

  1. tomcat-[view -> controller -> service -> dao -> mySQL]

分布式架构：

  1. tomcat-[view:PC] --> tomcat-[controller]
  2. tomcat-[view:phone] --> tomcat-[controller]
  4. tomcat-[controller] --> tomcat-[service->redis->dao->MySQL]

后端项目架构，采用 Dubbo 的生产者和消费者的理论，创建服务提供方和服务消费方两个工程，通过 Maven 聚合工程来搭建，模块划分如下：

  1. ----------------------------------------------
  2. > 服务提供 <
  3. lagou-edu-parent - pom 聚合父工程，统一依赖设置
  4. lagou-edu-entity - jar 工程，封装实体类
  5. lagou-edu-dao - jar 工程，封装与数据库打交道的部分
  6. lagou-edu-service - web 工程，暴露服务的接口和实现
  8. ----------------------------------------------
  10. > 服务消费 <
  11. lagou-edu-web - web 工程，接收前端工程发来的请求，远程调用服务并消费
  12. ----------------------------------------------

URL 命名

  • 查询（get 开头）：http://localhost:8002/course/getList
  • 保存（save 开头）：http://localhost:8002/course/saveXx
  • 更新（update 开头）：http://localhost:8002/course/updateXx

接口响应格式

  1. /**
  2.  * Data Transfer Object
  3.  * 数据传输对象
  4.  */
  5. @Data
  6. @AllArgsConstructor
  7. @NoArgsConstructor
  8. @ToString
  9. public class ResponseDTO<T> implements Serializable {
  10.     private static final long serialVersionUID = 1L;
  11.     // 操作状态
  12.     private int state;  
  13.     // 状态描述
  14.     private String message;  
  15.     // 相应内容
  16.     private T content;
  17.     ...
  18. }
