开源框架数据库连接池dbcp的使用方法

package com.mysql.demo;

import java.io.InputStream;
import java.sql.Connection;
import java.sql.SQLException;
import java.util.Properties;

import javax.sql.DataSource;

import org.apache.commons.dbcp.BasicDataSourceFactory;

//运用开源数据库连接池DBCP
//引用dbcp.jar和pool.jar,读取dbcp的配置文件。引用的时候直接getConnection或getDataSource
public class sqlpooling {

	private static DataSource ds=null;
	static{
		try{
		Properties p=new Properties();
		InputStream in=sqlpooling.class.getClassLoader().getResourceAsStream("dbcpconfig.properties");
		p.load(in);
		BasicDataSourceFactory factory=new BasicDataSourceFactory();
		ds=factory.createDataSource(p);//
		}
		catch(Exception e)
		{
			e.printStackTrace();
		}

	}
	public static DataSource getDataSource()
	{
		return ds;
	}
	public static Connection getConnection() throws SQLException
	{
		return ds.getConnection(); //dbcp的Connction()
	}

}
