项目编号:BS-XCX-010

一，项目简介

本系统 主要实现一个针对培训机构进行宣传和信息管理的信息化管理系统，系统一是对内部的学生选课及成绩管理，一是通过小程序对外进行宣传 并提供了小程序管理后台数据的功能。前端使用微信小程序开发实现，主要实现一些静态数据的展示和宣传功能，后台主要使用SSM框架开发实现完成对教师、学生和课程的基本信息管理。主要功能如下

微信小程序端：

1.小程序端管理员实现对信息模块的管理，包含课程、讲师、学员三类模块。

2.小程序端用户实现各类模块内容的浏览。

Web后台管理端：

1.Web端管理员实现对信息模块的管理；

2.Web端讲师实现对培训机构学员课程成绩打分等功能；

3.Web端学员实现对培训机构课程的报名、退选以及课程成绩查看等功能；

二，环境介绍

语言环境：Java:  jdk1.8

数据库：mysql: mysql5.7

应用服务器：Tomcat:  tomcat8.5.31

开发工具：IDEA或eclipse

相关技术：

1. 微信小程序（js、css前端基础）：前端小程序页面；
2. SSM框架（Spring+SpringMVC+Mybatis）：微信小程序界面需要调用的接口以及后台的管理系统；
3. Maven：项目管理必备的技术；
4. Shiro框架：保证系统安全的框架；
5. Bootstrap前端框架：Web后台管理端的后台界面；

三，系统展示

五，项目总结

本项目主要为培训机构的内部进行信息化的管理，并对培训机构进行相应的宣传，主要通过小程序+后台管理服务模块开发实现，通过前后端分离的方式来进行。
