how can I load russian(cyrillic, utf-8) text from message_ru_RU.properties in spring boot?

Question

I have scheduler. Each 5 sec I get some items from DB and send push notifications to android. But Text in this notifications in Rusian language. In feature we wand support different languages, and now i tried create some templates. I have property file for message templates: messages_ru_RU.properties and I have string in this file: notification.message=%s. На сумму: %s. Карта: %s notification.message=%s. На сумму: %s. Карта: %s

I need load this String from property and repalse %s to my values. Now I create config an service:

@Configuration
public class LocaleConfig {

  @Bean
  public LocaleResolver localeResolver() {
    SessionLocaleResolver slr = new SessionLocaleResolver();
    Locale defaultLocale = new Locale("ru");
    slr.setDefaultLocale(defaultLocale);
    return slr;
  }
  @Bean
  public ReloadableResourceBundleMessageSource messageSource() {
    ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
    messageSource.setBasename("classpath:messages");
    messageSource.setCacheSeconds(3600); //refresh cache once per hour
    return messageSource;
  }
}

and service:

@Component
public class MessageByLocaleServiceDefault implements MessageByLocaleService {

  private final MessageSource messageSource;

  @Autowired
  public MessageByLocaleServiceDefault(MessageSource messageSource) {
    this.messageSource = messageSource;
  }

  @Override
  public String getMessage(String id) {
    Locale locale = LocaleContextHolder.getLocale();
    return messageSource.getMessage(id, null, locale);
  }
}

and I try load string from property like this:

String messagePlaceholder = messageByLocaleService.getMessage("notification.message");

But I see this:

My question - how can I load russian(cyrillic, utf-8) text from message.properties in spring boot?

My property file saved in utf-8 encoding.

Make sure to also set the MessageSource encoding properly by configuring the setDefaultEncoding() property:

@Bean
public ReloadableResourceBundleMessageSource messageSource() {
    ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
    messageSource.setBasename("classpath:messages");
    messageSource.setCacheSeconds(3600);
    messageSource.setDefaultEncoding("UTF-8"); // Add this
    return messageSource;
}

According to the API documentation, the default is ISO-8859-1:

Default is none, using the java.util.Properties default encoding: ISO-8859-1.

Also, be aware that SessionLocaleResolver only works for user sessions. If you're going to use the MessageSource in combination with a scheduled task, it's not going to work.

You should check the following:

• idea file encoding (Default encoding for properties file should be UTF-8)
• code configuration ResourceBundleMessageSource call method setDefaultEncoding("UTF-8")
