Using ENUM for Profile, but expecting a String

I'm trying to use an Enum to define the different profiles my Spring application might use.

This is my enum Profiles.java

public enum Profiles {

    DEVELOPMENT("dev"),
    TEST("test"),
    PRODUCTION("prod");

    private final String code;

    private Profiles(String code) {
        this.code = code;
    }
}

I'm using it in a file to configure the properties place holders.

@Configuration
public class PropertyPlaceholderConfig {

    @Profile(Profiles.DEVELOPMENT)
    public static class DevelopmentConfig {
        @Bean
        public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() throws IOException {
            PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer = new PropertySourcesPlaceholderConfigurer();
            propertySourcesPlaceholderConfigurer.setIgnoreUnresolvablePlaceholders(Boolean.TRUE);
            propertySourcesPlaceholderConfigurer.setLocation(new ClassPathResource("props/application-dev.properties"));
            return propertySourcesPlaceholderConfigurer;
        }
    }

    @Profile(Profiles.TEST)
    public static class TestConfig {
        @Bean
        public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() throws IOException {
            PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer = new PropertySourcesPlaceholderConfigurer();
            propertySourcesPlaceholderConfigurer.setIgnoreUnresolvablePlaceholders(Boolean.TRUE);
            propertySourcesPlaceholderConfigurer.setLocation(new ClassPathResource("props/application-test.properties"));
            return propertySourcesPlaceholderConfigurer;
        }
    }

    @Profile(Profiles.PRODUCTION)
    public static class ProductionConfig {
        @Bean
        public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() throws IOException {
            PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer = new PropertySourcesPlaceholderConfigurer();
            propertySourcesPlaceholderConfigurer.setIgnoreUnresolvablePlaceholders(Boolean.TRUE);
            propertySourcesPlaceholderConfigurer.setLocation(new ClassPathResource("application-test.properties"));
            return propertySourcesPlaceholderConfigurer;
        }
    }
}

However it is complaining at @Profile that its getting incompatible types, got Profiles expected String. I feel like I'm missing something really silly.
