spring.profiles.active priority for application-{profile}.properties

Question

I would like to know the priority of the application-{profile}.properties files, if multiple spring.profiles.active are added.

For example:

• Let say, I have this spring.profiles.active=profile1,profile2
• And in my src/main/resources, I have these files application-profile1.properties and application-profile2.properties
• If both of the files config the same property, but with different values, which one will be the one shown?

I have read this and but it doesn't cover this topics here.

Thanks in advance.

Answer 1

According to the documentation, the last profile specified wins.
In your example : spring.profiles.active=profile1,profile2, the properties of profile2 should overwrite the properties of profile1.

In the point 24.4 Profile-specific Properties of the documentation, you can read :

If several profiles are specified, a last-wins strategy applies. For example, profiles specified by the spring.profiles.active property are added after those configured through the SpringApplication API and therefore take precedence.

Answer 2

First Spring loads default profile (application.properties) and then it overrides it with your additional profiles in the same order you listed them. So in your case profile2 values will override everything you defined in profile and application.properties

The simplest way is to write very simple application and just check it:)
