零碎介绍

随着数字化技术衰亡，各种应用软件笼罩各行各业，大大推动了产业倒退。然而，在外卖点餐畛域，事实问题依然存在，例如订单解决效率低、库存治理简单、客户服务程度不一以及数据分析能力有余等。为解决这些问题，本文研发了一款基于微信小程序与Spring Boot的外卖点餐零碎，旨在晋升效率和管理水平，优化顾客体验。

本外卖订餐零碎交融了先进技术与实际，采纳Spring Boot框架开发后端，借助MySQL数据库存储数据，并通过微信小程序实现用户端。零碎的翻新体现在全面晋升了管理效率和顾客服务。首先，它实现了一站式治理，帮助管理人员和餐厅经理解决订单、治理库存、追踪销售数据、治理餐厅信息及菜单等。其次，零碎为顾客提供了便捷的服务与反对，包含订单追踪、配送和领取等性能。最初，外卖订餐零碎具备用户敌对的界面和多功能模块，如订单、菜单、库存、用户治理及报告生成等，使得管理人员可能高效地经营餐厅，晋升顾客服务和满意度，从而促成业务增长。

4.2 零碎功能模块设计

零碎后盾面向管理员，提供了以下功能模块：

1.登录：管理员须要登录后盾零碎以进行各项操作和治理。

2.零碎设置：包含菜单治理、角色治理、用户治理、日志治理和数据备份等，不便管理员进行系统配置和保护。

3.外卖美食治理：涵盖美食分类管理、美食列表、口味列表、公司信息、流动列表、红包治理、订单列表、退款列表和评估列表等性能，使管理员可能全面掌控平台的经营状况，及时处理各类事务。

小程序前台则面向普通用户，提供了以下功能模块：

1.登录：用户登录后能够享受更多的个性化服务。

2.菜品浏览：用户能够查看各种美食，筛选心仪的菜品。

3.菜品分类浏览：用户能够依据菜品类别进行筛选，疾速找到所需美食。

4.点餐：用户选定菜品后，能够间接下单。

5.商家信息：用户能够查看商家的根本信息，理解商家的背景和特色。

6.购物车：用户能够将选定的菜品退出购物车，对立进行结算。

7.地址治理：用户能够增加和治理收货地址，确保外卖精确送达。

8.订单治理：用户能够查看订单状态，跟踪订单进度，申请退款等。

9.集体核心：用户能够查看个人信息，批改个人资料，查看积分、优惠券等。

10.退出登录：用户在实现操作后能够平安退出零碎。

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
