}
}

2.工具类
packagecom.cir.util;importjava.sql.Connection;importjava.sql.DriverManager;importjava.sql.SQLException;public classDBUtil {//数据库连接地址
private static String URL = "jdbc:mysql://localhost:3306/test?useSSL=false&serverTimezone=UTC";//数据库用户名
private static String UserName = "root";//数据库密码
private static String Password = "18735";public staticConnection getConnection()
{ Connection Conn=null;try{
Class.forName("com.mysql.cj.jdbc.Driver");
System.out.println("加载驱动成功");
}catch(ClassNotFoundException e) {//TODO Auto-generated catch block
e.printStackTrace();
}try{//通过DriverManager类的getConenction方法指定三个参数,连接数据库
Conn =DriverManager.getConnection(URL, UserName, Password);
System.out.println("连接数据库成功!!!");//返回连接对象//return Conn;
}catch(SQLException e) {//TODO: handle exception
e.printStackTrace();
}returnConn;
}
//还应涉及对数据表的操作
}
