如何在Windows下查看JAVA端口占用明细

from：http://qindongliang.iteye.com/blog/2157425

在linux想要查看某个端口的占用情况，我们可以使用ps -ef | grep 端口号来查看某个进程的端口占用情况，那么在windows上，如何查看呢？ 

起因：散仙在win7上启动jetty时，发生端口占用，日志异常如下：

从异常中，我们可以轻易看出是8983端口，被占用了，然后再次启动时，出现叠加端口，就会报上述异常，那么如何定位，查找，占用的端口号呢？ 



1，打开windows上的cmd窗口 
2，使用netstat -aon | findstr "8983"查看端口所在进程 
3，然后使用tasklist | findstr "进程id" 找出具体的程序所在主服务 
4,最后使用taskkill /f /t /im 进程名称 杀死进程 

截图如下： 






定位到异常所在服务后，查看有关服务，是否冲突，然后关掉即可（关掉之前，确认是否真的可以停掉，以免影响一些其他的服务，正常运行）！
