基于java的微信互助学习平台设计与实现
一、前言
在设计微信互助学习平台时，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服务功能。本微信互助学习平台管理员功能有个人中心，学生管理，课程分类管理，课程信息管理，课程评价管理，学习计划管理，留言板管理，学习论坛，系统管理等。 小程序用户可以注册登录，查看课程，课程评价，指定学习计划，留言等操作。因而具有一定的实用性。本微信互助学习平台，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，使得微信互助学习平台管理工作系统化、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，能够有效的提高微信互助学习平台管理效率。
二、系统功能设计
三、系统实现
系统管理员可以对课程分类信息进行添加，修改，删除以及查询操作。具体界面如图5.2所示。
图5.2 课程分类信息管理界面
系统管理员可以对课程信息进行添加，修改，删除以及查询操作。界面如下图所示：
图5.3课程信息管理界面
系统管理员可以对校园资讯信息进行添加修改删除操作。界面如下图所示：
图5.4 校园资讯信息管理界面
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
用户对课程信息查看，收藏以及评论操作。界面如下图所示：
图5.6 课程信息界面
四、数据库设计
1、实体ER图
