Spring Boot @ConditionalOnProperty not resolving property

Question

In my Spring Boot project (SB v2.4.4) I'm trying to conditionally enable a configuration class using @ConditionalOnProperty:

@ConditionalOnProperty(
        value = "feature1.enabled",
        havingValue = "true",
        matchIfMissing = false
)
@Configuration
public class NewConfig {
    ...
}

Property feature1.enabled is declared in a features.properties file that is loaded using a second configuration class:

@Configuration
@PropertySource("classpath:features.properties")
public class FeaturesConfig {
}

Properties declared in features.properties are correctly loaded, but @ConditionalOnProperty doesn't seem to resolve feature1.enabled.

I also tried to annotate NewConfig class with a @DependsOn("featuresConfig"), but nothing changes.

The only thing that seems to work is to move feature1.enabled in application.properties.

So why this is not working? What's wrong with my configuration?

Answer 1

As suggested by M.Denium in his comment, I solved the issue adding this command line argument on application launch:

-Dspring.config.additional-location=classpath:/features.properties

adding features.properties file as an additional configuration location for my application, fixes the property resolution issue in @ConditionalOnProperty.
