模拟CSDN请求，做一点事

 需求：无聊，就是玩玩。

 功能：指定博客地址，随机访问某一篇博文，增加该博文访问量。

 实现：1、通过Httpclient实现模拟访问操作。

              2、指定博客列表URL，通过HTMLParse爬虫框架分析HTML节点，获取所有博文URL，随机模拟操作。

              3、使用线程Thread Sleep设置定时访问博文URL。

              4、使用Java Service Wrapper打包成Windows服务，每天自动启动并自动运行程序（可选）。

准备工作：

需要准备以下LIB：可根据情况删剪LIB。

 详细代码：

以上代码，Main方法直接运行即可。

注意事项：

1、建议是30秒~一分钟刷一次，如果间隔时间太短，CSDN是不会增加访问量的。

2、http://blog.csdn.net/programmer_sir?viewmode=contents是我的博客列表页面，指定你的博客列表URL即可。

3、代码更新于2014年9月份10号。后续如果CSDN对IP访问限制住了，那你可以使用JAVA代理，这样的话CSDN是无法限制刷流量的，关于如何使用JAVA代理，可以参考我很早前的一篇博文。

4、如果你只写了一篇博客，CSDN的LIST标签不是SPAN好像，你要改以下方法。

getNodeByClass

5、那些只看不评论的程序员，注定是很难提升的。哈哈。。
