一、项目概述

本学生管理系统旨在提供一个方便的界面，用于学校或机构管理学生信息，包括学生基本信息、课程成绩等。

二、系统架构

系统采用经典的三层架构，包括前端使用JavaSwing，后端采用Java Servlet，数据库使用MySQL。

三、技术选型

• JavaSwing作为前端UI框架。
• Java Servlet处理后端逻辑。
• MySQL数据库存储学生信息。

四、安装和配置

1. 下载项目源代码。
2. 安装Java Development Kit (JDK)。
3. 设置数据库连接配置。
4. 运行系统初始化脚本。

1.学生信息管理

1. 在主界面选择“学生管理”。
2. 点击“添加学生”按钮，输入学生信息。
3. 查看学生列表和详细信息。

2.成绩管理

1. 进入“成绩管理”模块。
2. 选择课程和学生，输入成绩。
3. 查看成绩报表。

五、数据库设计

student 表

• sid：学生ID，自增长。
• sname：学生姓名。
• snumber：学号。
• sage：学生年龄。
• sphone：学生电话。
• saddress：学生地址。

示例数据：

sid	sname	snumber	sage	sphone	saddress
1	styhs	123456789	23	12345678	郑州

user 表

• uid：用户ID，自增长。
• uname：用户名。
• upassword：用户密码。

示例数据：

uid	uname	upassword
1	user	123456
2	user1	111111
3	user2	111111
