Invalid property arrays overriding in profile-specific property files

[mkadan]

Spring Boot 1.2.2.RELEASE

I'm using @ConfigurationProperties annotation on class to populate properties.
Consider having these property files:

application.yml:

urls:
                      - http://www.aargauerzeitung.ch
                      - http://www.bzbasel.ch
                      - http://www.basellandschaftlichezeitung.ch
                      - http://www.limmattalerzeitung.ch

application-dev.yml:

urls:
                      - http://google.com

When launching the app with -Dspring.profiles.active=dev I got the following value for "urls":

                      - http://google.com
                      - http://www.bzbasel.ch
                      - http://www.basellandschaftlichezeitung.ch
                      - http://www.limmattalerzeitung.ch

but it should be just:

                      - http://google.com

Profile specific properties are loaded in addition to application.properties so this is expected behavior (see http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#boot-features-external-config-profile-specific-properties).

So is there a way to reduce the size of an array from the profile-specific properties?

[philwebb]

I'm not sure that we offer a convenient way to do this at the moment. The ConfigFileApplicationListener class is responsible for loading the configuration.

Probably the easiest way at the moment is to create two profiles. There is also an open issue (#1219) that we plan to address in 1.3.
