零碎介绍

摘要

随着挪动互联网的迅速倒退和古代生活节奏的放慢，外卖点餐曾经成为人们日常生活中的一种普遍现象。为了满足市场需求和进步用户体验，本文介绍了一款外卖点餐零碎的设计与实现。

该外卖点餐零碎基于零碎开发和设计思维的总体工作，次要实现外卖点餐系统管理，容许用户通过指令实现操作。零碎前端采纳 Vue、HTML、CSS 技术构建，使用户、管理员、商家和骑手能够交互并查看订单、菜品、配送单、商品评估等信息。后端采纳 SpringBoot 技术，运行于 Linux 环境，次要负责解决前端申请，执行逻辑操作，并与 MySQL 5.7 数据库交互，实现数据的增删改查等操作。

管理员模块，次要应用 SpringBoot 进行后端逻辑解决，并通过 Vue 进行前端页面展现，负责首页、集体核心、用户治理、商家治理、菜品分类管理、骑手治理、系统管理、菜品治理、订单治理、配送单治理、商品评估治理等操作。用户、商家和骑手模块也同样应用这套技术进行实现，性能涵盖了订单治理、菜品治理、配送单治理、商品评估治理等各个方面。

总的来说，本文具体论述了外卖点餐零碎的设计与实现，零碎具备丰盛的性能和易用性，有助于进步用户体验和满足不同角色的需要。通过古代技术栈的使用，零碎可能满足高性能、高可用性和可扩展性的要求，为外卖行业的倒退做出了踊跃奉献。

2 需要剖析

2.1 性能需要剖析

零碎功能设计是在零碎开发和设计思维的总体工作的根底上实现的。该零碎的次要工作是实现外卖点餐系统管理，使用户能够通过指令实现整个外卖点餐零碎的操作。

根本能够实现软件的性能，零碎性能框图如图 2 - 1 所示：

1）开发实现外卖点餐零碎的整个零碎程序；

2）管理员：首页、集体核心、用户治理、商家治理、菜品分类管理、骑手治理、系统管理、菜品治理、订单治理、配送单治理、商品评估治理等模块信息的查看及相应操作；

3）用户：实现首页、集体核心、订单治理、配送单治理、商品评估治理、我的珍藏治理等相应操作；

4）商家：实现首页、集体核心、菜品治理、订单治理、配送单治理、商品评估治理、我的珍藏治理等相应操作；

5）骑手：首页、集体核心、订单治理、配送单治理、商品评估治理等相应操作；

6）根底数据管理：实现零碎根本信息的增加、批改及删除等操作，并且依据需要进行留言信息的查看及回复相应操作。

环境须要

1. 运行环境：最好是 java jdk 1.8，咱们在这个平台上运行的。其余版本实践上也能够。
2.IDE 环境：IDEA，Eclipse,Myeclipse 都能够。举荐 IDEA;
3.tomcat 环境：Tomcat 7.x,8.x,9.x 版本均可
4. 硬件环境：windows 7/8/10 1G 内存以上；或者 Mac OS；
5. 数据库：MySql 5.7 版本；
6. 是否 Maven 我的项目：否；

技术栈

后端：Spring+SpringMVC+Mybatis
前端：JSP+CSS+JavaScript+jQuery

应用阐明

应用 Navicat 或者其它工具，在 mysql 中创立对应名称的数据库，并导入我的项目的 sql 文件；
应用 IDEA/Eclipse/MyEclipse 导入我的项目，Eclipse/MyEclipse 导入时，若为 maven 我的项目请抉择 maven;
若为 maven 我的项目，导入胜利后请执行 maven clean;maven install 命令，而后运行；
将我的项目中 springmvc-servlet.xml 配置文件中的数据库配置改为本人的配置;
运行我的项目，在浏览器中输出 http://localhost:8080/ 登录
