一 原理简介
对大量域名的注册情况进行自动化检测，细分开来讲就是多次对单个域名的注册情况的检测。而对单个域名的检测我们可以使用万网提供的接口（http://panda.www.net.cn/cgi-bin/check.cgi?area_domain=xxx.yy），具体细节可以参考我以前写过的一篇文章：http://www.zifangsky.cn/2015/11/java中的get和post请求，使用万网接口判断域名是否已被注/
因此，在这篇文章里，我主要实现的是：（1）做了一个比较直观的图形化界面；（2）支持从外部导入字典文件进行自动化检测；（3）支持对多种后缀的检测，包括可以自定义后缀；（4）同时还实现了对探测结果的导出。
运行后的截图基本上是这样的：
界面和导入导出功能不用多说，实现起来很简单，而且代码中有详细注释，一看就懂。这里需要说明的是，为了让检测的状态在界面中实时显示出来（左边的正在检测以及右边的可注册和超时域名），我选择了在一个新的线程里执行文件读取，联网查询这类比较费时的工作，同时使用了SwingUtilities.invokeLater来通知事件分发线程及时更新界面。具体原理和基本实现可参考我写的这篇文章：http://www.zifangsky.cn/2015/12/java中事件分发线程（edt）与swingutilities-invokelater相关总结/

三 效果测试
注：其实这个软件仅仅只是一个初始版本，还很不完善。因为万网的接口是免费的原因，因此不仅不能使用多线程，而且我还人为的在每次请求后暂停了一秒钟。后期我根据情况或许会将这个软件升级成多线程版的，尽请期待
