前言
相信大家平时肯定会收到朋友发来的链接，打开一看，哦，需要投票。投完票后弹出一个页面（恭喜您，您已经投票成功），再次点击的时候发现，啊哈，您的IP（***.***.***.***）已经投过票了，不能重复投票。这时候，我们可能会想，能不能突破ip地址的限制进行刷票呢？有了这样的想法，那就去做吧，下面我将介绍我这个简单的刷票系统，仅供有需求的园友们参考。
1.系统设计
系统主要实现的是突破IP限制进行刷票，其中，由IP采集模块负责从互联网上爬取代理IP，放入阻塞队列，该任务会定期执行。之后由投票模块从阻塞队列中获取IP，并进行设置，然后进行投票。系统流程图如下：
2.系统技术
系统使用HttpClient + JSoup + 多线程来完成刷票，HttpClient用于进行投票，JSoup用于解析页面，多线程技术用于分离任务，使得分工更加明确。使用到了生产者消费者模式，该模式直接使用BlockingQueue来实现。
3、系统介绍
系统主要分为三个模块：
①.IP采集模块
②.投票模块
③.IP信息模块
其中，IP采集模块主要是从互联网爬取IP代理信息，并将该信息放入阻塞队列，这样就可以伪造IP，进行多次投票。
其中，投票模块从IP采集模块放入阻塞队列取出IP信息，并设置代理，找到投票入口地址，然后进行投票操作。
其中，IP信息模块主要是对爬取的IP信息进行了封装，方便其他模块进行操作。
3.1.IP采集模块
IP采集模块流程图如下
几点说明：
1.系统使用的代理IP站点URL为http://www.kuaidaili.com/，www.xicidaili.com。
2.提取IP信息为提取单条IP信息，并判断历史IP表是否已经存在，若存在，表示之前已经加入过此IP信息，则直接丢弃，反之，则加入队列并加入历史IP表。
3.此任务会定期开启，如一个小时爬取一次代理IP。
3.2.投票模块
投票模块流程图如下
几点说明：
1.投票网站http://www.hnxdf.com/vote/，我们选取的第一位进行投票，分析出投票的入口为http://www.hnxdf.com/vote/iRadio_vote.asp?VoTeid=215。
2.根据IP采集模块放入队列的IP信息进行设置，然后进行投票。
3.3.IP信息模块
此模块主要对从网站爬取的IP信息进行了封装，方便其他模块进行操作。
4、系统代码框架
系统的整个代码框架如下
其中，bean包的IpInfo封装了爬取的IP信息。
其中，entrance包的Vote为系统的入口。
其中，thread包的IPCollectTask为爬取代理IP任务，VoteThread为进行投票线程。

6.系统总结
此系统很简单，想清楚思路之后很快就能够写出代码，系统运行时，由于代理IP站点提供的免费IP质量不是太高，有效的IP地址还是很少，所有效果不是特别理想，此系统功能也很简单，但是各位园友可以在此基础上去发挥自己的想象力，定制属于自己的投票系统。
结束语
至此，整个系统分析就已经完成了，其中，图也画得不是太规范，还请各位园友海涵。也谢谢各位园友观看。
