you can use maven's profiles. Placeholder replacement is performed during build based on the profiles configuration in maven.

you can name the jdbc.yaml file application-jdbc.yaml .
set the jvm parameter -Dspring.profiles.active=jdbc when starting spring-boot , so that spring-boot will load the application.yaml configuration file and the corresponding profile configuration file.

multiple profile are separated by commas

$ java -Dspring.profiles.active=jdbc,jdbc2 -jar [xxx].jar
