Description:

Web server failed to start. Port 8082 was already in use.

Action:

Identify and stop the process that's listening on port 8082 or configure this application to listen on another port.

Possible causes:

Either you have already been running the application
Or another application is running in the same port

Solutions:

Configure the application to listen on another port(ex: 8081)

If you are using applcation.properties,
```
server.port=8081
```
If you are using application.yml
```
server:
   port: 8081
```
Identify and stop the process that's listening on a port(8082)
- window
- ubuntu
- mac
and restart your application

If you are using cmd or git bash , use the command :

netstat -ano

or further fine grain query :

nestat -ano | grep {port addr}

(note : grep only works in linux or gitbash , use findstr for cmd)

to identiy all the PID s that are currently running , which uses the particular port address that you want to use in your application. If the PIDs are not relevant , you could kill the PIDs using the command kill -9 {pid}. After that you could start your application in the same port.

Another easy approach is to use another port address which is not used by any other application. Just set the property server.port=8086 in your application.properties, or pass it as an argument when you start the application.
