Profile specific custom property files in Spring boot

Question

Wanted to check if Spring boot offers help to use configuration file apart from application.properties file. Ex: my-custom.properties file that can be profile specific, ex:

1. my-custom-dev.properties for dev profile
2. my-custom-uat.properties for uat profile

Edit: The question is that, I have the normal application-{env}.property file, apart from that, there are other property files in accord to their data content (ex: DB specific properties for logging, that I want to store in `db-log.properties, How would I make the other files profile sensitive?

Answer 1

In addition to application.properties files,

profile-specific properties can be defined with following convention: application-{profile}.properties.

The Environment has a set of default profiles (by default, [default]) that are used if no active profiles are set(In other words, if no profiles are explicitly activated, then properties from application-default.properties are loaded)

To run multiple profiles:

1.application-prod.properties

2.application-dev.properties

mvn spring-boot:run -Dspring-boot.run.profiles=dev,prod

3.application.properties (Default profile)

mvn spring-boot:run

4.Command Line Args with custom property files

spring.config.name - Set configuration files names(comma separated values) spring.config.location - Set the locations where Spring Boot will find your externalized configuration files.

java -jar hello-world.jar --spring.config.name=application,conf --spring.config.location=classpath:/external/properties/,classpath:/com/learn/../../

Answer 2

Additionaly to the application.properties file, you can define as application-{profile}.properties as you want. The chosen file is determinated at launch, following the profile you have selected.

Answer 3

You can use it with active profile

@Configuration
@PropertySource("classpath:my-custom-${spring.profiles.active}.properties")
