Profile-specific@在application.yaml中設(shè)置配置文件后，配置類不起作用

我想從application.properties遷移到application.yaml，并使用配置文件和每個配置文件不同的@Configuration-classes。

預(yù)期行為：TestEnvPrinter.printEnv: env = test

實(shí)際行為：DefaultEnvPrinter.printEnv(): env = default, profile = test

為什么Spring只使用DefaultAppConfig而忽略TestAppConfig @Configuration-class？

一些應(yīng)用程序文件：

application.yaml:

spring:
  profiles:
    active: test
app:
  env: default

application-test.yaml:

app:
  env: test

DefaultAppConfig.java:

@ComponentScan("ru.albert_rayanov")
@Configuration
@PropertySource("classpath:application.yaml")
public class DefaultAppConfig {
    @Bean
    public static PropertySourcesPlaceholderConfigurer properties() {
        PropertySourcesPlaceholderConfigurer result = new PropertySourcesPlaceholderConfigurer();
        YamlPropertiesFactoryBean yamlFactory = new YamlPropertiesFactoryBean();
        yamlFactory.setResources(new ClassPathResource("application.yaml"));
        result.setProperties(Objects.requireNonNull(yamlFactory.getObject()));
        return result;
    }
}

TestAppConfig.java:

@Configuration
@Profile("test")
@PropertySources(value = {@PropertySource("classpath:application-test.yaml")})
public class TestAppConfig {
    @Bean
    public EnvPrinter envPrinter() {
        return new TestEnvPrinter();
    }
}

DefaultEnvPrinter.java:

@Component
@Primary
public class DefaultEnvPrinter implements EnvPrinter {
    @Value("${app.env}")
    private String env;

    @Value("${spring.profiles.active}")
    private String profile;

    @Override
    public void printEnv() {
        System.out.println("DefaultEnvPrinter.printEnv(): env = " + env + ", profile = " + profile);
    }
}

TestEnvPrinter.java:

@Component
public class TestEnvPrinter implements EnvPrinter {

    @Value("${app.env}")
    private String env;

    @Override
    public void printEnv() {
        System.out.println("TestEnvPrinter.printEnv: env = " + env);
    }
}

ProfileWorker.java:

@Component
public class ProfileWorker {
    private final EnvPrinter envPrinter;

    public ProfileWorker(EnvPrinter envPrinter) {
        this.envPrinter = envPrinter;
    }

    public void doWork() {
        envPrinter.printEnv();
    }
}

Main.java:

public class Main {
    public static void main(String[] args) {
        ApplicationContext context = new AnnotationConfigApplicationContext(DefaultAppConfig.class);
        context.getBean(ProfileWorker.class).doWork();
    }
}
