Spring Cloud : Load Message Sources from config server

问题

I'm working on Spring cloud project (Spring Boot + Eureka API ) that contains client , registry and a config server , so I need to load Message properties from the config Server :

I have already a config server with application.properties well configured and available from client server .

My current MessageSource Bean in the client Micro-service:

@Configuration
public class Config {

    @Bean
    public ReloadableResourceBundleMessageSource messageSource() {
        ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
        messageSource.setBasename("classpath:/messages/messages");
        messageSource.setDefaultEncoding("UTF-8");
        return messageSource;
    }
}

If you want to load them from the config service, you just need to point the config path for it.

The values on this class are read from the bootstrap.yml.

I have a folder called "locale" on the application.yml level, with the file "messages_en_GB.properties" inside.

Structure:
  application.yml
  locale (folder)
     messages_en_GB.properties

@Configuration
public class MessageConfig {

  private static final Logger LOGGER = LoggerFactory.getLogger(MessageConfig.class);

  @Value("${spring.cloud.config.uri}")
  private String cloudUri;

  @Value("${spring.cloud.config.label}")
  private String cloudLabel;

  @Value("${spring.profiles.active}")
  private String profile;

  @Value("${spring.cloud.config.enabled:false}")
  private boolean cloudEnabled;

  @Bean
  @RefreshScope
  public ReloadableResourceBundleMessageSource messageSource() {
    ReloadableResourceBundleMessageSource messageSource =
        new ReloadableResourceBundleMessageSource();
    messageSource.setBasename(buildMessageLocation());
    messageSource.setDefaultEncoding("UTF-8");
    return messageSource;
  }

  private String buildMessageLocation() {

    if (Strings.isNullOrEmpty(cloudUri) || Strings.isNullOrEmpty(profile) || Strings
        .isNullOrEmpty(cloudLabel) || !cloudEnabled) {
      LOGGER.info("The cloud configuration is disabled, using local messages properties file");
      return "classpath:locale/messages";
    }

    return cloudUri + "/" + profile + "/" + profile + "/" + cloudLabel + "/locale/" + "messages";
  }
