数据库连接DBConnection

java Web最简单的功能就是增删改查了，那么第一步就是连接数据库了，虽然很简单，但是好记性不如烂笔头，写下来闲着无聊看一眼

package com.db;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class DBConnection {
	public static Connection getConnection(){
		Connection con=null;
		try {
			Class.forName("com.mysql.jdbc.Driver");
			con=DriverManager.getConnection("jdbc:mysql://localhost:3306/students","root","123456" );
		} catch (ClassNotFoundException e) {
			System.out.println("没有找到数据库驱动");
		} catch (SQLException e) {
			System.out.println("数据库连接失败");
		}
		return con;
	}
	
	public static void close(Connection con){
		if(con!=null){
			try {
				con.close();
			} catch (SQLException e) {
				System.out.println("数据库关闭异常");
			}
		}
	}

}
