基于javaweb+mysql的ssm投票管理系统(java+jsp+ssm+javabean+mysql+tomcat)

运行环境

Java≥8、MySQL≥5.7、Tomcat≥8

开发工具

eclipse/idea/myeclipse/sts等均可配置运行

适用

课程设计，大作业，毕业设计，项目练习，学习演示等

功能说明

投票管理系统，分为前端和后台管理模块

前端用户可以登录注册、查看投票信息，登录后可以进行投票，也可以查看自己的历史投票记录

后台管理模块管理员登录后可以管理用户信息、管理投票主题和子项、查看投票详情、查看投票图表统计信息等

目前投票方式支持单选只能投一次、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方式，投票主题可以设置开始和结束时间，结束后不能再进行投票
