Rewrite Spring configuration using java annotations instead xml for import statement with SpEl

Question

I have old Spring project that is using xml configuration. And I want rewrite this configuration using java annotations (for some reasons). In this xml configuration I have this creepy code:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns....>
    <!-- ... -->
    <import resource="classpath:/spring/${service.loader:service}-loader.xml" />
    <!-- ... -->
</beans>

How I may rewrite this import statement using java annotations?

@Configuration
@Import({
     // TODO What do I need write here?
})
public class SpringConfig {
     // ...
}

Update:

Note: I want rewrite all xml files, and I need import java class (from property or default). I think I need condition statement for this.

@Configuration
public class Loader {
  /*configurations in classpath:/spring/${service.loader:service}
  -loader.xml file */

}

@Configuration
@Import({Loader.class})
public class SpringConfig {
     // ...
}

You may want to import from xml basedc onfiguration you may use the below tag to import resource in annotation based spring configuration.

@ImportResource("/spring/${service.loader:service}-loader.xml")

But if you are converting every context xml into corresponding annotation based @Conguration then you should do it with below tag

@Import(OtherConfiguration.class)

If you use spring-boot then you can do something like this

@SpringBootApplication
@ImportResource("classpath:myconfig.xml")
public class MyClasss{

   public static void main(String[] args) {
      SpringApplication.run(Application.class, args); //Up and running
   }

}
