Port already in use

🆘 How I solved the errors that I encountered

Error message

Description:

Web server failed to start. Port 8080 was already in use.

Action:

Identify and stop the process that's listening on port 8080 or configure this application to listen on another port.

Solution

The error message and the solution for this issue is very straight forward.
In my case, I was already using port 8080 for another program, so I changed the port number to 8081 by announcing it in the application.properties file. The number of the port can be changed.

Full code

server.port=8081
