Eclipse 显示在使用 tomcat v9 运行 Web 应用程序时端口正在使用中，即使我更改了它

Question

when I try to run a dynamic webpage project, I face ab error that some other process is already using those port numbers. I restarted the PC but it didn't solve the problem. I've tried changing the port numbers but that doesn't work.
Here are the ports I changed it to:

Answer 1

From the image attached it shows that port 80805 is busy, already in use

netstat -aon | findstr 80805

The number that is shown as last column of above result is process ID of program that is using your port.

Suppose that number comes to 13360. Then use the following command to know exact process using your port.

tasklist | findstr 13360

Answer 2

Port numbers are only 16-bit. Pick ones under 65,535.
