httpclient 4.0 使用 - 访问开心网的各种组件 例子 转

在网上查了好长时间，发现httpclient的例子都是讲httpclient 3.X的。httpclient 4.0的例子简直是凤毛麟角。只好自己上官网仔细了查了下文档和官网示例，受益匪浅啊！
    由于前段时间对“开心网”的“开心大亨”很感兴趣，但是每隔一段时间就需要看一下最新的价格变化，很是麻烦，由于我就想起用httpclient写个程序，自动查看最新的价格，并和前次的价格做比较，好让我可以选择利润最大的进行投资。
   
    程序用到的包如下，为了附件的瘦身，请大家自己下载啊，附件中是没有这些lib的啊。
    commons-collections-3.2.1.jar
    commons-configuration-1.6.jar
    commons-io-1.4.jar
    commons-lang-2.4.jar
    commons-logging-1.1.1.jar
    httpclient-4.0.jar
    httpcore-4.0.1.jar

    由于只是例子，而且httpclient4.0的结构变化很大，自己对其理解也不是很深，此程序只是个入门程序，如果有高手在的话，希望大家可以提出宝贵的意见。
    程序写的不是很美观，但意在让大家明白如何简单的使用httpclient4.0，所以没有对程序做任何的重构的整理，望大家多多谅解啊。

    程序代码如下：
