如何关闭Windows 7中打开的端口？

Question

当我尝试启动我的基于java的服务器时，有一条消息说该端口已经在使用......并且我的所有Java Web服务器都已停止...所以，如果有人可以帮助我，我会很感激...

Answer 1

If there is really still a process that has the port open, you can easily check for that (and close the process) via TCPView . It might be that the port is just lingering (for example due to not being shutdown properly), in which case you'd have to wait for the socket to close and check that the code is clear with regard to that.

Answer 2

I was trying to establish socket communication between PC ( JAVA Server )<--> Android ( Client )

on Debugging, popped the problem : Address already in use

instant/feasible resolution i found out was to:

• run cmd as adminstrator
• netstat -abn
• find the process listening to the port of intrest
• terminate the process from task manager

PS : Unlike from an external application mentioned in previous answers, steps in this answer allows you to find out the used ports with the resources already present.

Answer 3

A few options... us TCPView to find the program that has the port open and kill it... reboot... just reset the network connection. Try those.
