基于java和微信小程序的考研论坛平台小程序设计与实现

一、前言

在设计考研论坛设计时，功能模块充分融合了用户与管理员的实际需求，实现了多元化且全面的考研论坛功能。本基于微信小程序的考研论坛设计管理员功能有个人中心，用户管理，网上书城管理，书籍分类管理，用户签到管理，留言板管理，交流论坛，系统管理，订单管理。用户可以注册登录，签到留言，购买书本等操作。因而具有一定的实用性。

本基于微信小程序的考研论坛设计，后台采用SSM框架，MYSQL数据库设计开发，微信小程序用微信开发者工具开发，充分保证系统的稳定性。系统具有界面清晰、操作简单，功能齐全的特点，使得基于微信小程序的考研论坛设计管理工作系统化、规范化。本系统的使用使管理人员从繁重的工作中解脱出来，实现无纸化办公，能够有效的提高基于微信小程序的考研论坛设计管理效率。

二、系统功能设计

三、系统实现

系统管理员可以对网上书城信息进行添加，修改，删除以及查询操作。具体界面如图5.2所示。

图5.2 网上书城信息管理界面

系统管理员可以对用户签到进行查看删除操作。界面如下图所示：

图5.4 用户签到管理界面

用户注册登录后可以在小程序首页看到相关信息和链接，可以搜索和点击操作。界面如下图所示：

图5.5 首页界面

用户对可以对各种图书搜索查查询，找到图书之后可以收藏和订购。界面如下图所示：

图5.6 图书订购信息界面

我的里面关于各项信息的连接，点击就可以跳转到对应的页面。界面如下图所示：

图5.7 我的界面

四、数据库设计

1、实体ER图

（1）设计的学生实体，其具备的属性如下图。

2设计的留言板实体，其具备的属性如下图。
