Conditionally load application context

How can I load a spring-beans xml file from one out of two locations?

• System.getProperty("conf.dir") + "/context.xml"


• classpath:/context.xml

This is what I started out with but I only want to load the first found context

@Configuration
@ImportResource({"${conf.dir}/context.xml", "classpath:/context.xml"})
public class AppConfig {
     @Autowire somethingFromAboveXmlContext;
}

I've looked into @Conditional but the solution becomes a bit non-intuitive.

@Configuration
@Conditional(AppContextCondition.class)
@ImportResource("${conf.dir}/context.xml")
@ImportResource("classpath:/context.xml")
public class AppConfig {
     @Autowire somethingFromAboveXmlContext;
}

Is there a manual approach to do what ImportResource does?
