You can simply set a system property on the server as follows…
-Dspring.profiles.active=test
Edit: To add this to tomcat in eclipse, select Run -> Run Configurations and choose your Tomcat run configuration. Click the Arguments tab and add -Dspring.profiles.active=test at the end of VM arguments. Another way would be to add the property to your catalina.properties in your Servers project, but if you add it there omit the -D
Edit: For use with Spring Boot, you have an additional choice. You can pass the property as a program argument if you prepend the property with two dashes.
Here are two examples using a Spring Boot executable jar file…
System Property
[user@host ~]$ java -jar -Dspring.profiles.active=test myproject.jar
Program Argument
[user@host ~]$ java -jar myproject.jar --spring.profiles.active=test
