Spring boot failed to start

Question

I have a error and I tried to figure out what was wrong for 2 hours and I can't fix it.

I ran my spring boot app using java -jar command, it's a package and it couldn't start.

I set the properties file to set the port for 80 and my firewalld is disabled and I ran on Centos7 machine. and I tried netstat command and there was no service for port 80 so it is not a port problem i think.

This is the errlog:

I believe that on Linux you seed to be a 'sudo'er to use port 80. Either run as superuser or use 8080. — NickJ, Jan 21 '19 at 13:57
@xerx593 yes so after this I tried with sudo, thank you but unfortunately, it was not a single problem — John Shim, Jan 21 '19 at 14:54
Does it work if you try port 8080? Also, check netstat -a to see if something is already using port 80. — Stephen M -on strike-, Jan 21 '19 at 16:41

The log says everything.

The Tomcat connector configured to listen on port 80 failed to start. The port may already be in use or the connector may be misconfigured.

That port is currently used, you might have other server using this port at the moment (another run/debug maybe?). Anyways, for development reasons I'd suggest to use different port at all.

In application.properties put server.port=8080 or something like that - smaller chance it's used by an other process.

I suppose spring-boot set its server port 8080 as a default. so I changed it to 80 with that method and it wasn't work but somehow it was solved, because I used embeded tomcat and its setting use servlet version 3.0 not 2.5 so i added dependency in my pom.xml and it fixed. thank you tho! – John Shim Jan 21 '19 at 14:59
