java学生管理系统
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
- 下载项目源代码。
- 安装Java Development Kit (JDK)。
- 设置数据库连接配置。
- 运行系统初始化脚本。
1.学生信息管理
- 在主界面选择“学生管理”。
- 点击“添加学生”按钮，输入学生信息。
- 查看学生列表和详细信息。
2.成绩管理
- 进入“成绩管理”模块。
- 选择课程和学生，输入成绩。
- 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 |
