A simple solution is to terminate the process (in IDE) and clean and rebuild project.

Your question is not complete. If you are getting error like below that means port 8080 is already being used.

The Tomcat connector configured to listen on port 8080 failed to start. The port may already be in use or the connector may be misconfigured.

Action:

Verify the connector's configuration, identify and stop any process that's listening on port 8080, or configure this application to listen on another port.

In this case you can either stop application that is running on thisport or simply use different port. On your application.properties file you can define port as 

server.port=8181
