Spring Boot: Multiple similar ConfigurationProperties with different Prefixes

Question

I\'m using Spring Boot and have two very similar services which I\'d like to configure in my application.yml.

The configuration looks roughly like this:

Answer 1

Javvanos example worked perfektly, except for JavaBean Validation.

I've had an annotation @NotNull on one of the properties:

public class ServiceProperties {
   @NotNull
   private String url;
   private String port;

   // Getters & Setters

}

As a consequence, the application startup failed with following error message:

***************************
APPLICATION FAILED TO START
***************************

Description:

Binding to target ch.sbb.hop.commons.infrastructure.hadoop.spark.SparkJobDeployerConfig@730d2164 failed:

    Property: url
    Value: null
    Reason: may not be null


Action:

Update your application's configuration

After removing the annotation, the application startet up with correct property binding. In conclusion, I think there is an issue with JavaBean Validation not getting the correctly initialized instance, maybe because of missing proxy on configuration methods.
