一、项目简介

高校校园交友微信小程序使用Java语言进行编码，使用Mysql创建数据表保存本系统产生的数据。系统可以提供信息显示和相应服务，其管理员高校校园交友微信小程序信息，查看高校校园交友微信小程序信息，管理高校校园交友微信小程序信息。

二、系统设计

2.1软件功能模块设计

在前面分析的管理员功能的基础上，进行接下来的设计工作，最终展示设计的结构图（见下图）。

（1）下图是论坛实体和其具备的属性。

三、系统项目部分截图

3.1个人中心管理

如图5.1显示的就是个人中心管理页面，此页面提供给管理员的功能有：个人中心的查询管理，可以删除个人中心、修改个人中心、新增个人中心，
还进行了对用户名称的模糊查询的条件
