Problem

A property which uses custom loader and contains placeholder inside it is not resolved.

Example:

spring:
  config:
    import: sm-stub://

app:
  environment: qa
  a-service-url: ${sm-stub://projects/my-project/secrets/${app.environment}_a-service_url/versions/latest}

Reproduction

Spring Boot version

In build.gradle you can switch the version of Spring between:

• 3.3 which resolves the value properly
• 3.4 which doesn't resolve

Test

Run the de.gorbatykh.spring_boot.property_resolving_bug.SpringBootPropertyResolvingBugApplicationTest.should_resolve_app_aServiceUrl test.

Application

Run the de.gorbatykh.spring_boot.property_resolving_bug.SpringBootPropertyResolvingBugApplication it will log the resolved value.
