篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了基于SSM实现学籍管理系统相关的知识，希望对你有一定的参考价值。
项目编号：BS-GX-026
运行环境
jdk8+tomcat8.5+mysql+IntelliJ IDEA(或eclipse)+maven
项目技术(必填)
spring+spring mvc+mybatis+layui+jsp+echarts
本系统是一个基于ssm+layui的学籍管理系统；
本系统比较简单，适用于新手，上手简单易操作，主要是帮助理解java web （ssm框架）项目的整体运行流程，附带着也熟悉一下这种项目的搭建；
本系统具有三种用户： 1.管理员：专业管理，班级管理，学生管理，老师管理，课程管理，开课管理以及用户管理 2.教师：成绩管理，学生查询 3.学生：选课管理，查看成绩
下面展示一下系统功能截图：
老师身份登陆
学生身份登陆
以上是基于SSM实现的学籍管理系统的部分功能展示，本系统功能完整，界面美观，适合做毕业设计使用。
