一 介绍
这一篇文章是紧接着上一篇文章（http://www.zifangsky.cn/2015/12/使用java开发多线程端口扫描工具/）写的，端口扫描的原理不用多少，我在上一篇文章中已经说过了，至于目的大家都懂得。在这一篇文章里，我主要是对端口扫描工具的继续完善，以及写出一个比较直观的图形界面出来，以方便我们测试使用。界面如下：
这个工具主要是实现了以下几点功能：（1）两种扫描方式，一种是只扫描常见端口，另一种是设置一个起始和结束端口，依次探测。当然，原理很简单，用for循环就可以了；（2）输入一个域名或者IP后，可以自定义扫描线程，这一点是非常有用的，因为有的服务器是装了360，云锁或者安全狗的，扫描线程过大或许会被封IP。
注：文末我会给出简易的可执行jar文件的下载链接
