Add additional parameters to Spring Boot app

Question

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...

Answer 1

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

Answer 2

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
