怎么选择佛山网站设计,株洲企业网站建设品牌,开放平台包括,wordpress怎样进入后台文章目录 一、项目演示二、项目介绍三、运行截图四、主要代码1. 分页获取预约数据代码2.保存预约信息代码3.修改订单状态代码 一、项目演示 项目演示地址#xff1a; 视频地址 二、项目介绍 项目描述#xff1a;这是一个基于SpringBootVue框架开发的充电桩管理系统。首先 视频地址 二、项目介绍 项目描述这是一个基于SpringBootVue框架开发的充电桩管理系统。首先这是一个前后端分离的项目代码简洁规范注释说明详细易于理解和学习。其次这项目功能丰富具有一个充电桩管理系统该有的所有功能。 项目功能此项目分为两个角色普通用户和管理员。普通用户有登录注册、浏览个人数据统计信息、管理个人信息、浏览运营商信息、浏览电站信息、浏览充电桩信息、预约充电桩、报修充电桩、管理个人预约信息、开始充电、结束充电、查看个人订单信息、支付订单、查看个人报修信息、查看个人告警信息、查看留言信息等等功能。管理员有查看全部数据统计信息、管理所有用户信息、管理所有运营商信息、管理所有电站信息、管理所有充电桩信息、管理所有预约信息、管理所有订单信息、管理所有报修信息、管理所有告警信息、管理所有留言信息等等功能。 应用技术SpringBoot Vue3.0 MySQL MyBatis Redis ElementUI-Plus Vite 运行环境IntelliJ IDEA2019.3.5 MySQL5.7项目压缩包中自带) Redis5.0.5项目压缩包中自带 JDK1.8 Maven3.6.3项目压缩包中自带 Node14.16.1项目压缩包中自带 三、运行截图 四、主要代码

1. 分页获取预约数据代码 /*** 分页获取预约数据* param pageDTO* return/Overridepublic ResponseDTOPageDTOAppointDTO getAppointList(PageDTOAppointDTO pageDTO) {AppointExample appointExample new AppointExample();//
