【免费】微信小程序投票评选系统(SpringBoot后端+Vue管理端) Java毕业设计_哔哩哔哩_bilibili
项目介绍
社会发展日新月异,用计算机应用实现数据管理功能已经算是很完善的了,但是随着移动互联网的到来,处理信息不再受制于地理位置的限制,处理信息及时高效,备受人们的喜爱。所以各大互联网厂商都瞄准移动互联网这个潮流进行各大布局,经过多年的大浪淘沙,各种移动操作系统的不断面世,而目前市场占有率最高的就是微信小程序,本次开发一套微信小程序投票评选系统有管理员和用户两个角色。管理员功能有个人中心,用户管理,投票主题管理,投票内容管理,投票记录管理,系统管理。用户可以注册登录,查看投票公告和投票内容,可以对投票内容进行投票操作,可以查看投票记录等。微信小程序投票评选系统服务端用Java开发的网站后台,接收并且处理微信小程序端传入的json数据,数据库用到了MySQL数据库作为数据的存储。这样就让用户用着方便快捷,都通过同一个后台进行业务处理,而后台又可以根据并发量做好部署,用硬件和软件进行协作,满足于数据的交互式处理,让用户的数据存储更安全,得到数据更方便。
