问题
I am wondering if it's possible to add spring's additional parameters such as -Dspring.profiles.active=prod to spring boot app in case of running it as a service.
I checked the script that was generated automatically by spring-boot-maven-plugin:
command="$javaexe -jar -Dsun.misc.URLClassPath.disableJarChecking=true $jarfile $@"
so maybe it can be done via maven plugin's options, but couldn't find any except of JVM arguments which is not so useful...

I couldn't find any solution including the one I described in question - it seems that plugin's additional params also don't work.
At the end I solved it by using systemd service approach.
Looks like that and works perfectly:
[Unit]
Description=Some app
After=syslog.target
[Service]
ExecStart=java -Dspring.profiles.active=production -jar /home/apps/monitoring-app-1.0.0.jar
[Install]
WantedBy=multi-user.target

You can use external configuration file for example.
Based on the documentation if you provide an application.properties file in the ./config directory next to the executed jar you can set up the active profile through that properties file.
Just use spring.profiles.active=myprofile in ./config/application.properties

Create a .conf file in the same directory with the same name as your executable jar e.g.
server-1.0-SNAPSHOT.jar server-1.0-SNAPSHOT.conf
JAVA_OPTS="-Xmx500m \
-Dspring.profiles.active=myprofile"
