关于数据库连接池的难题,DBCP,想了一晚上。高分请高手指点。

connection hashcode is 24968504

我在经过4分钟后又执行了一次connection,发现connection的hashCode不变,如果是新的connection

hashCode会不一样才对。

[02:47:58,062] [ExampleAction,33]

dataSource hashCode is 22958990

active num is 0

idle num is 1

connection hashcode is 24968504

以下是我的代码：

BasicDataSourceHolder.java

---------------------------------------------------------------

package com.dolphin.manager.example.dao.impl;

import javax.sql.DataSource;

import org.apache.commons.dbcp.BasicDataSource;

import com.noname.framework.util.config.Config;

public class BasicDataSourceHolder {

public static DataSource dataSource;

public static DataSource createDataSource() {

String driverClass=Config.getProperty("database.jdbc.driver");

String dburl=Config.getProperty("database1.connetion.url");
