摘 要
5G通讯时代的到来使得“万物互联”深入人心。在这样的背景下,智能家居近一步走入大众的生活,各种智能产品如:智能电视、智能冰箱、智能空调等越来越成为消费者的首选。在人们不断追求智能家居的安全性、便利性和舒适性的情况之下,智能家居迎来大发展,销量与日俱增。为迎合智能家居的发展浪潮,结合电商平台蓬勃发展现状,使智能家居展受到更多的关注,本系统以智能家居销售为研究对象,使用JAVA语言开发,基于B/S模式和MySQL数据库,实现了智能家居销售的订单管理与设备信息管理。基于B/S的智能家居销售系统能够协助消费者选择、购买以及管理智能设备,拓展智能家居用户数量,使智能家居的发展更上一层楼。

3.2.2功能需求
本系统主要功能分为两个方面一方面是为用户提供智能家居设备最新资讯,包括设备功能介绍、生产介绍以及价格等,同时提供不同智能家居设备的参数对比,旨在帮助用户在众多智能家居设备中挑选最合适的产品。此外系统会提供家居的购买服务,并且可以保存购买订单,在保证用户购买产品的质量的同时,便于用户行使售后服务。另一方面用户通过后台管理,可以对智能家居进行检索、升级、检测智能家居的使用情况等功能,登录系统后系统会提醒用户需要更新固件的设备,保证设备版本与时俱进。
用户:用户可以查看网站信息,还能实施智能家居设备信息、智能家居资讯查看,享有购物车,在线客服,用户订单信息,使用设备管理,升级设备管理,订单管理等服务。用户用例图如图3-1所示。
管理员:管理员在登录系统后主要负责用户信息的管控,实施智能设备类型的分类,智能设备信息的管理以及对用户的订单进行查看与管理。管理员用例图如图3-2所示。

3.3系统流程分析
3.3.1数据流程
本系统在用户未登录的情况下,仅可以了解智能家居最新资讯功能。用户登录前需要先进行注册,成功注册并登录的用户在设备查询功能中可以进行智能家居查询,并可以对中意的智能设备添置购物车,完成下单服务。系统同时会保存用户订单信息。
本智能家居销售系统的用户购买商品数据流图如图3-3所示。

环境需要
1.运行环境:最好是java jdk 1.8,我们在这个平台上运行的。其他版本理论上也可以。
2.IDE环境:IDEA,Eclipse,Myeclipse都可以。推荐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项目:否;
技术栈
1. 后端:Spring+SpringMVC+Mybatis
2. 前端:JSP+CSS+JavaScript+jQuery
使用说明
1. 使用Navicat或者其它工具,在mysql中创建对应名称的数据库,并导入项目的sql文件;
2. 使用IDEA/Eclipse/MyEclipse导入项目,Eclipse/MyEclipse导入时,若为maven项目请选择maven;
若为maven项目,导入成功后请执行maven clean;maven install命令,然后运行;
3. 将项目中springmvc-servlet.xml配置文件中的数据库配置改为自己的配置;
4. 运行项目,在浏览器中输入http://localhost:8080/ 登录
