Spring Boot Application immediately shuts down after starting

Question

I am working currently on a project which includes the Spring Framework. Everything is working as aspect but there is one problem. When I try to start my application onto my lap

Answer 1

I met the same problem, I fix by these steps as below:
update file application.yml

1- remove:

main:
    web-application-type: none

2- if your change server port already, it's still error:

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

solution: move server port config on the top of yml file

Done! it's for my case.
