零碎介绍

摘要

5G通信时代的到来使得“万物互联”深入人心。在这样的背景下，智能家居近一步走入公众的生存，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。在人们一直谋求智能家居的安全性、便利性和舒适性的状况之下，智能家居迎来大倒退，销量一劳永逸。为投合智能家居的倒退浪潮，联合电商平台蓬勃发展现状，使智能家居展受到更多的关注，本零碎以智能家居销售为钻研对象，应用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治理与设施信息管理。基于B/S的智能家居销售零碎可能帮助消费者抉择、购买以及治理智能设施，拓展智能家居用户数量，使智能家居的倒退更上一层楼。

3.2.2性能需要

本零碎次要性能分为两个方面一方面是为用户提供智能家居设施最新资讯，包含设施性能介绍、生产介绍以及价格等，同时提供不同智能家居设施的参数比照，旨在帮忙用户在泛滥智能家居设施中筛选最合适的产品。此外零碎会提供家居的购买服务，并且能够保留购买订单，在保障用户购买产品的品质的同时，便于用户行使售后服务。另一方面用户通过后盾治理，能够对智能家居进行检索、降级、检测智能家居的应用状况等性能，登录零碎后零碎会揭示用户须要更新固件的设施，保障设施版本与时俱进。

用户：用户能够查看网站信息，还能施行智能家居设施信息、智能家居资讯查看，享有购物车，在线客服，用户订单信息，应用设施治理，降级设施治理，订单治理等服务。用户用例图如图3-1所示。

管理员：管理员在登录零碎后次要负责用户信息的管控，施行智能设施类型的分类，智能设施信息的治理以及对用户的订单进行查看与治理。管理员用例图如图3-2所示。

3.3零碎流程剖析

3.3.1数据流程

本零碎在用户未登录的状况下，仅能够理解智能家居最新资讯性能。用户登录前须要先进行注册，胜利注册并登录的用户在设施查问性能中能够进行智能家居查问，并能够对中意的智能设施添置购物车，实现下单服务。零碎同时会保留用户订单信息。

本智能家居销售零碎的用户购买商品数据流图如图3-3所示。

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
