问题
Is there a defined order when multiple profiles are used for a property resolution.
I have yaml configuration file:
name: none
---
spring:
profiles: prod
name: prodName
---
spring:
profiles: dev
name: devName
When application runs with no (default) profile, none
is printed. For dev/prod profiles devName/prodName is printed (so far so good).
When I tried to define profile as dev,prod
prodName
is printed,when I specify prod,dev
devName
is printed.
Is this something I can rely on? I mean is it specified in Spring? I didn't find it here.

application.yml
name: none

spring:
profiles: dev
name: devName

spring:
profiles: prod
name: prodName

Topics
There was a question which I'd refer to as topics - Multiple properties file for a single spring profile
While one can use @PropertySource
with property files, it cannot be used with YAML files. The only solution I know at the moment is to used e.g. -Dspring.config.additional-location=classpath:topic1.yml
