学生成绩管理系统（SSM+MySQL+JSP）

开发工具：Eclipse
前端技术：
基础：html+css+JavaScript
框架：JQuery+H-ui
后端技术：Spring+SpringMVC+mybatis
模板引擎：JSP
数据库：mysql 5.7.27
jdk版本：1.8.0_251

一、功能概述

学生管理系统的用户包括学生、教师及管理员。
（1）学生可以对个人的各科成绩进行查询、个人信息修改、选课、修改登录密码等操作。
（2）教师可以对学生信息、教师个人信息、课程信息、成绩等进行管理，实现对这些信息的查询、录入、添加、修改、删除等操作。
（3）管理员可以对学生、教师、课程、成绩信息进行管理，实现对这些信息的查询、录入、添加、修改、删除以及权限管理等操作。

二、数据库表结构

成绩表（Score）：

学生表（student）：

课程表（subject）：

教师表（teacher）：

用户表（user）：

三、项目结构

四、配置SSM文件
