How to read multiple spring profile files through #value annotation in Kotlin? - kotlin

Question

I have two spring profile files application-test.yml and application-prod.yml, with some properties in each file.
I have set
spring:
profiles:
active: test, prod
in my application.yml file and added the #Profile(value= ["test", "prod"]) in my configuration file.
Now, my question is how to read the content of the two files and what do I need to pass in #Value?? This is how I implemented it:
#Profile(value= ["test", "prod"])
#Configuration()
class myMessege(
#Value("${"??????"}")
private val newMessege: String) {
#Bean
fun readMessage {
println(newMessege)
}
The application-test.yml is
spring.profiles: test
key:
- name: tom
roles:
- student
- teacher
- friend
and the application-prod.yml is
spring.profiles: test
key:
- name:lisa
roles:
- doctor
- nurse
- patient
How to return the key from both files?

Answer 1

Properties in Spring operate in the same namespace so a property identifier like "key.name" in application-test.yml identifies the same thing as application-prod.yml
If properties are declared twice, the last declared properties file wins (or overrides) - think of this like CSS
If you want additive settings (e.g. names from different files all get rolled into the same property then you'll have to do this yourself, e.g. by naming the property "key.test.name" and "key.prod.name" and then look for these in code and merge them.
