How to read @ConfigurationProperties for different prefixes in single class

I have 2 different application.yaml at github for spring-boot application. Below are the sample content for both :

first application.yaml : application: name: sample-service second application.yaml : common: kafka: topic: test

I created one Configuration class(abc.java) with @ConfigurationProperties( prefix='common.kafka') and another Configuration class(xyz.java) with @ConfigurationProperties( prefix='application')

Here in xyz.java, I am inheriting abc.java. While executing xyz.java, I am not able to access properties of abc.java, getting NPE. It is achieved if I keep same prefix hierarchy i.e. @ConfigurationProperties( prefix='application')

In short, I want to access both application.yaml configurations in single class of spring-boot micro service. However, I am not able to achieve it. Please provide any suggestion to access both properties.

Why do you have to inherit one class into the another?

Isn't it better to have new class that has the two @ConfigurationProperties annotated classes as properties.

E.g.

@Component
public class Properties {

    @Autowired
    ApplicationProperties applicationProperties;

    @Auworied
    KafkaProperties kafkaProperties;
}

and just use your Properties.class wherever you need to
