Using Expressions in Spring application.properties file

Question

Can expressions be used as a right-hand-side value in a Spring application.properties file?

For example, something like this:

logging.level.com.acme=         


        

Answer 1

Use profile based properties file.

In application-dev.properties : logging.level.com.acme=WARN

and in application-prod.properties : logging.level.com.acme=DEBUG

FYI when spring boot doesn't find a propertie in a profile based file it use the value in the default one . So you can set properties in application.properties and override them in a profile based file when their value changed.
