Can @PropertySources be chosen by Spring profile?

Add the overriding @PropertySource in a static inner class. Unfortunately, you must specify all property sources together which means creating a “default” profile as the alternative to “override”.

@Configuration
public class MyConfiguration
{
    @Configuration
    @Profile("default")
    @PropertySource("classpath:defaults.properties")
    static class Defaults
    { }

    @Configuration
    @Profile("override")
    @PropertySource({"classpath:defaults.properties", "classpath:overrides.properties"})
    static class Overrides
    {
        // nothing needed here if you are only overriding property values
    }

    @Autowired
    private Environment environment;

    @Bean
    public Bean bean() {
        ...
        // this.environment.getRequiredProperty("foo");
        ...
    }
}
