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:

serviceA.url=abc.com
serviceA.port=80

serviceB.url=def.com
serviceB.port=8080

Is it possible to create one class annotated with @ConfigurationProperties and set the prefix at the injection point?

e.g.

@Component
@ConfigurationProperties
public class ServiceProperties {
   private String url;
   private String port;

   // Getters & Setters
}

and then in the Services itself:

public class ServiceA {

   @Autowired
   @SomeFancyAnnotationToSetPrefix(prefix="serviceA")
   private ServiceProperties serviceAProperties;

   // ....
}

Unfortunately I haven't found something in the documentation about such a feature... Thank you very much for your help!

Answer 1

I achieved almost same thing that you trying. first, register each properties beans.

@Bean
@ConfigurationProperties(prefix = "serviceA")
public ServiceProperties  serviceAProperties() {
    return new ServiceProperties ();
}

@Bean
@ConfigurationProperties(prefix = "serviceB")
public ServiceProperties  serviceBProperties() {
    return new ServiceProperties ();
}

and at service(or someplace where will use properties) put a @Qualifier and specified which property would be auto wired .

public class ServiceA {
    @Autowired
    @Qualifier("serviceAProperties")
    private ServiceProperties serviceAProperties;

}
