dbconn.java

我实习时候的设计

package cn.yxh.util;

import java.sql.*;


public class DBConn {
	private static String driver = "com.mysql.jdbc.Driver";
	private static String url = "jdbc:mysql://localhost:3306/xuanke?user=root&password=1234";
	private static Connection conn ;
	
	public static Connection getConn() {
		try{
			Class.forName(driver);
			conn = DriverManager.getConnection(url);
		}catch(Exception e) {
			e.printStackTrace();
		}
		return conn;
	}
}
