当时写这个程序是公司要求有个测试环境测试多用户情况，我匆匆忙忙的用了个上午写完后，一测试能用，就交差了，不过后来在多次使用的时候发现了有时候程序回莫名退出，不过由于时间等原应，就没有在仔细修改了，朋友门如果有新区的话，可以自己修改一下，如果有什么想法也希望和我联系！
功能说明：可以输入需要访问的url（注意需要加"http://"才可以，我当时程序中偷懒了，和想象中的模拟用户数，然后确定就可以了，如果你的输入都正确的话，程序会自动创建你希望的线程数目，然后一直运行，知道你电极了“停止”按扭，线程才会结束。在执行期间，线程会将访问一个网页所用到的时间，显示到文本框中，方便用户统计。
不多说了，看程序吧
