How to internationalize the specific text message in Spring Boot?

Currently I'm implementing a service for sending notifications (SMS, for example) to customers. Service is written in Java, based on Spring Boot.

I'd like to send a message in the recipient's language.

So basically I'd like to have a method, taking some id of the message with the desired localization ("en", "fr", "es") and giving back the correct String. Also configuring some default language (like "en") would be great - to fall back to it if the desired language is not supported.

Any suggestions how to achieve this with Spring Boot?

P.S.: Sorry, yes, I've tried "googling". I've found several internationalization examples, but most of them seem not useful, as they're intended for the whole user interface, not a specific message.

As of now I've resolved the issue initializing MessageSource manually:

@PostConstruct
public void initMessageSource() {
    ReloadableResourceBundleMessageSource reloadableMessageSource = new ReloadableResourceBundleMessageSource();
    reloadableMessageSource.setDefaultEncoding("UTF-8");
    reloadableMessageSource.setBasename(config.getI18nBundleBase());
    reloadableMessageSource.setCacheSeconds(config.getI18nCacheSeconds());
    this.messageSource = reloadableMessageSource;
}

Autowiring initialized my messageSource with empty DelegatingMessageSource, so internationalization did not work.

First, you need to create a couple resource files. Put a file called messages_en.properties and another called messages_fr.properties in src/main/resources.

In the en file put a line:

hello.world=Hello World!

In the fr file put a line:

hello.world=Bonjour le monde!

Then where ever you need to get this text inject a MessageSource

@Autowired private MessageSource messageSource;

Then you can use it to get the text

messageSource.getMessage("hello.world", null, locale);

You'll need to pass in the locale of the user to that method. You can setup a LocaleResolver to do that if you need.
