将swing的页面和功能代码分开编写，更清晰直观，方便后续调用，封装了按钮美化和释放资源函数。 其中的icon图片地址自己找图片并修改地址。
5.数据库启动函数
package mysql;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
/**
* 数据库连接得到conn对象
*/
public class SqlConnect {
private static final String DRIVER = "com.mysql.cj.jdbc.Driver";
private static final String URL = "jdbc:mysql://localhost:3306/campusrunmanagementsystem?useSSL=false";
private static final String USER = "root";
private static final String PASSWORD = "123456";
public SqlConnect() {
}
public static Connection getConnection() {
Connection conn = null;
try {
Class.forName(DRIVER);
conn = DriverManager.getConnection(URL, USER, PASSWORD);
System.out.println("提示：数据库连接成功~");
} catch (ClassNotFoundException e) {
System.err.println(e.getMessage());
} catch (SQLException e) {
System.err.println("异常：数据库连接失败！");
}
return conn;
}
}
返回一个conn对象便于后续调用，这里注意的是MySQL的配置信息改为自己的。

9.总结
该项目为期末项目，用时一天半，制作较为粗糙，仅能实现基本的增删改查，且本人对swing界面编写十分生疏，本文仅供参考，欢迎各位留言指正。
