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

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 blocke.printStackTrace();System.out.println("数据库连接失败");}}	
}
