SSM 框架基于 JavaWeb 在线投票系统的设计与实现源码
零碎阐明
依据系统分析,将在线投票管理系统分为前台功能模块和后盾功能模块。其中零碎前台性能实现用户注册、用户登录、浏览、投票、投票核心和投票历史等性能。零碎前台性能如图 5 - 2 所示:
图 5 -2 零碎前台功能模块结构图
用户注册:用户填写用户名、明码和性别,点击注册按钮进行注册。
用户登录:用户填写曾经注册的用户名和明码,点击登录按钮进行登录。
浏览:用户能够浏览在线投票管理系统中公共凋谢内容。
投票:用户抉择本人须要的投票,针对主题,勾选选项,进行投票操作。投票形式反对单选只能投一次、单选一天只能投一次、多选只能投一次、多选一天只能投一次等四种形式。
投票核心:在线投票管理系统展现所有投票主题供用户抉择。
投票历史:存储用户曾经投票的历史内容,用户登陆前方可查看。
零碎后盾性能实现以下性能,投票信息管理、具体投票查看、用户信息管理、投票信息统计和管理员登录等性能。零碎后盾性能如图 5 - 3 所示:
图 5 -3 零碎后盾功能模块结构图
投票信息管理:管理员进行投票信息管理,能够治理投票主题和投票选项。针对投票主题,能够增加投票主题(须要填写主题名称、主题类型、开始工夫、完结工夫和主题简介)、查看主题、批改主题和删除主题;针对投票选项治理,能够增加选项(须要填写选项名称和抉择所属主题)、查看选项、批改选项和删除选项。
具体投票查看:管理员查看投票的详细信息,以列表模式显示,每条投票详细信息包含:投票 ID、用户名、投票主题、投票选项、总投票数和投票工夫等信息。
用户信息管理:管理员进行用户信息管理,能够增加用户(须要填写用户名、明码、性别和状态)、查看用户信息、批改用户信息和删除用户。
投票信息统计:管理员进行投票信息统计,默认显示所有的投票主题统计,输出搜寻主题名称后显示单个主题的投票统计。
管理员登录:管理员输出用户名、明码和验证码,点击登录按钮,进行登录操作。
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
