Is it possible to have application.properties depend on multiple profiles?

There are 4 ways I know.

1. insert .yaml or .properties programmatically like Asi Bross Said. Use ResourceLoader or YamlPropertySourceLoader to insert.

2. Use .yaml. but it will be replace when you have a another spring project to dependent it.

3. Use properties instead of profiles. (For api project)

   1. Use one @PropertySource to define properties file A.
   2. Get the variables from properties file A and assign them to the parameters in another @PropertySource file path expression.

   For example:

   resources
   /-application.properties  <-- remove or empty,because it will be override by application project
   /-moduleA
        /-application.properties               <-- Intellij can identify properties files started with application-
        /-application-mysql-dev.properties
        /-application-psql-dev.properties
        /-application-psql-prod.properties
   

   The content of resources/moduleA/application.properties :

   moduleA.custom.profile1=mysql
   moduleA.custom.profile2=dev
   

   Content of Java Config file:

   @SpringBootApplication
   @PropertySources({
           @PropertySource("/moduleA/application.properties"),
           @PropertySource("/moduleA/application-${moduleA.custom.profile1}-${moduleA.custom.profile2}.properties"),
   })
   public class ModuleConfig {}
   

4. Use properties instead of profiles. (For application project)

   resources
   /-application.properties
   /-application-mysql-dev.properties
   /-application-psql-dev.properties
   /-application-psql-prod.properties
   

   The content of resources/application.properties :

   moduleA.custom.profile1=mysql
   moduleA.custom.profile2=dev
   

   The content of SpringMvcApplication.java:

   @SpringBootApplication
   @PropertySource("/application-${moduleA.custom.profile1}-${moduleA.custom.profile2}.properties")
   public class SpringMvcApplication {...}
