一、系统介绍

1.运行环境

开发工具：Eclipse/IDEA

JDK版本：jdk1.8

Mysql版本：5.7

2.技术说明

Java+Swing+Mysql

3.系统功能

学生成绩管理系统是广泛使用的一种信息管理系统，在学生成绩管理系统中，需要能处理各班信息、各班下属学生的个人信息及每个学生学习成绩信息。班级信息包括班级编号、班级名称，学生信息包括学号、姓名、性别、所属班级、联系方式等，及各门课程的成绩。与班级相关的操作是查看已有班级、新增班级、修改班级名称、删除班级、录入新生信息等；与学生相关的操作是查看已有学生、修改学生基本信息、删除学生、录入成绩、修改成绩、根据姓名、学号、班级、课程等多条件查询学生成绩，并可以依据多种条件进行排序。

4.数据库ER图表

二、系统实现

1.整体结构 

2.用户注册、登录

对所有的输入都有进行正则校验，用户名有2-6位中文和6-18位英文或数字限制，且不能输入特殊符号；密码有6-18位英文或数字限制。如下图 

3.增加学生

可以对学生的信息进行修改、学生查询、增加删除。所有输入操作均有防暴力输入和正则判断。

4.模糊查询学生信息

5.成绩管理和查询

6.查询成绩 

 

7.课程更改
