Setting Spring #Profile from JNDI for SpringBoot - spring

Question

I'm deploying my SpringBoot Application to a Tomcat 8.5 container.
Similar as described here: http://docs.spring.io/spring-boot/docs/current/reference/html/howto-traditional-deployment.html I modified my SpringBootApplication, so it's deployable as war.
#SpringBootApplication
public class Application extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(Application.class);
}
}
Similiar to this question Activating Spring #Profile Using JNDI I wan't the application to select the active Profile using an JNDI entry.
I added an EnvironmentApplicationContextInitializer identical to the one shown in the accepted answer.
However: I do not use any web.xml. So the profile is not being picked up and used.
How do I make the SpringBootApplication using the EnvironmentApplicationContextInitializer?

Thanks to M Deinum's comment I found a solution:
#SpringBootApplication
public class Application extends SpringBootServletInitializer {
public static void main(String[] args) {
// this would be used if run via java -jar service.war
// SpringApplication app = new SpringApplication(Application.class);
// CustomApplicationContextInitializer initializer = new CustomApplicationContextInitializer();
// app.addInitializers(initializer);
// app.run(args);
SpringApplication.run(Application.class, args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
// this will be used within an app container
CustomApplicationContextInitializer initializer = new CustomApplicationContextInitializer();
return builder.initializers(initializer).sources(Application.class);
}
}
Note the builder.initializers(initializer) part.
