Create Micronaut Nested Configuration where child model classes are from external library

[subash89]

Hi, To use @ConfigurationProperties() I need to make sure the child model classes should be inner classes. But if some classes are 3rd party external library, we cannot add them as inner classes in my main config.

Example:

Following example is a working one where I can define ChildConfig class as an inner class. But my question is what if this ChildConfig is coming from another dependency for my project where I no longer define the ChildConfig as a inner class. In such case how to get it working.

@ConfigurationProperties("myconfig")
class MyConfig {

  @Getter
  @Setter
  private ChildConfig child;
  
  @Getter
  @Setter
  public class ChildConfig {
     private String name;
     private String value;
 
  }
}
