一、项目介绍
这款Java swing实现的学生信息管理系统和jsp版本的功能很相似，简单的实现了班级信息的增删改查，学生信息的增删改查，数据库采用的是mysql，jdk版本不限，是Java学习者学习参考非常好的一个小项目。
二、项目展示
登录
主界面
添加班级信息界面
班级信息管理界面
学生信息管理主界面
修改学生信息管理主界面
删除记录
三、源码展示
数据库工具类
java
public class DbUtil {
private String dbUrl="jdbc:mysql://localhost:3306/db_student_swing?characterEncoding=utf8"; // 数据库连接地址
private String dbUserName="root"; // 用户名,填写你自己的数据库用户名
private String dbPassword=""; // 密码，你自己的用户名密码，这个就是我的，所以我不修改了
private String jdbcName="com.mysql.jdbc.Driver"; // 驱动名称
/**
* 获取数据库连接
* @return
* @throws Exception
*/
public Connection getCon()throws Exception{
Class.forName(jdbcName);
Connection con=DriverManager.getConnection(dbUrl, dbUserName, dbPassword);
return con;
}
/**
* 关闭数据库连接
* @param con
* @throws Exception
*/
public void closeCon(Connection con)throws Exception{
if(con!=null){
con.close();
}
}
public static void main(String[] args) {
DbUtil dbUtil=new DbUtil();
try {
dbUtil.getCon();
System.out.println("数据库连接成功！");
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
System.out.println("数据库连接失败");
}
}
