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

Following this post Guide to @ConfigurationProperties in Spring Boot you can create a simple class without annotations:

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

   // Getters & Setters
}

And then create the @Configuration class using @Bean annotation:

@Configuration
@PropertySource("classpath:name_properties_file.properties")
public class ConfigProperties {

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

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

Finally you can get the properties as follow:

@SpringBootApplication
public class Application implements CommandLineRunner {

    @Autowired
    private ConfigProperties configProperties ;

    private void watheverMethod() {
        // For ServiceA properties
        System.out.println(configProperties.serviceA().getUrl());

        // For ServiceB properties
        System.out.println(configProperties.serviceB().getPort());
    }
}
