Is there a way to include properties file in another properties file?

Question

I'd like to avoid cluttering the application.properties file with lots of things than, in my opinion, would be better in a separate file.

application.properties should be something like

@include module1.properties
@include module1.properties
...
###################################
######### Spring Misc #############
###################################

# Direct log to a log file
logging.file=/tmp/kmp-manager.log

#local listening port
server.port=8082

spring.profiles=nr_dev nr_testing production
spring.profiles.active=production

spring.datasource.platform=postgresql

java.security.egd=file:/dev/./urandom

Is this at all possibile? If not, what would be a sane way to avoid cluttering?

Answer 1

Spring Boot Spring Boot 2.4 has added a feature for importing

We can now use spring.config.import=developer.properties to import other file. Check this blog post for more details

Answer 2

It's possible in YML file and the configuration are very simple

EXAMPLE:

To include properties of application-DATABASE.yml file in application.yml, use

spring:
  profiles:
    include: DATABASE

[EDIT - for 2.4.0 and above]

spring.profiles.group.prod=DATABASE

OR

Add the file name in application.properties

spring.config.import=classpath:application-DEV.yml,classpath:application-UDEV.yml,classpath:application-PRO.yml,classpath:application-SBA.yml
