对配置文件使用ENUM，但需要一个字符串

我正在尝试使用一个枚举来定义我的Spring应用程序可能使用的不同配置文件。

这是我的枚举Profiles.java

public enum Profiles {

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

    private final String code;

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

我在文件中使用它来配置属性占位符。

@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;
        }
    }
}

但是，它在@Profile抱怨它的类型不兼容，Profiles期望使用String。我觉得我真的很想念一些东西。
