基于java和小程序的公交信息在线查询系统小程序设计与实现
一、前言
本文介绍了微信小程序公交信息在线查询系统的开发全过程。通过分析微信小程序公交信息在线查询系统信息管理的不足，创建了一个计算机管理微信小程序公交信息在线查询系统信息的方案。文章介绍了微信小程序公交信息在线查询系统的系统分析部分，包括可行性分析等，系统设计部分主要介绍了系统功能设计和数据库设计。
本微信小程序公交信息在线查询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，线路信息管理，站点分类管理，站点信息管理，周边分类管理，周边信息管理，系统管理等。用户功能有个人中心，线路信息管理，站点信息管理，周边信息管理等。。因而具有一定的实用性。
本站后台采用Java的SSM框架进行后台管理开发，可以在浏览器上登录进行后台数据方面的管理，MySQL作为本地数据库，微信小程序用到了微信开发者工具，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，使得微信小程序公交信息在线查询系统信息管理工作系统化、规范化。
关键词：微信小程序公交信息在线查询系统；SSM框架；MYSQL
二、系统功能设计
三、系统实现
小程序用户是需要注册才可以进行登录的，登录后的首页界面如下图所示：
图5.5 系统首页
在小程序里点击我的，会出现关于我的界面，在这里可以修改个人信息，以及可以点击其他功能模块。界面如下图所示：
图5.6 我的菜单
用户查看线路信息，可以收藏。界面如下图所示：
图5.6 线路收藏页面
管理员可以对线路信息进行添加，查询修改，删除操作。具体界面如图5.2所示。
图5.3 线路信息管理界面
系统管理员可以管理站点分类。界面如下图所示：
图5.4 站点分类管理界面
系统管理员可以添加，修改，删除周边信息。界面如下图所示：
图5.4 周边信息管理界面
四、数据库设计
（1）线路信息的实体属性图如下：
