dbtest.java

可以实现增加删除修改和登陆的功能 是用流行的框架实现的

package com.ibm.action;

import java.sql.*; 

public class DBTest { 
public static void main(String[] args) { 
String driver = "com.mysql.jdbc.Driver"; 
String url = "jdbc:mysql://localhost:3306/test"; 
String user = "root"; 
String password = "lihui"; 
try { 
Class.forName(driver); 
Connection conn = DriverManager.getConnection(url, user, password); 

if(!conn.isClosed()) 
System.out.println("数据库连接成功！"); 
conn.close(); 
} 
catch(ClassNotFoundException e) { 
System.out.println("找不到驱动程序"); 
e.printStackTrace(); 
} 
catch(SQLException e) { 
e.printStackTrace(); 
} 
} 
}
