Internationalization

Internationalization (i18n) is the process of developing applications and services so that they can be customized for different languages and cultures across the world. It is also called ;localization. The goal of internationalization or localization is to build applications that can offer content in multiple languages and formats.

Spring Boot has built-in support for internationalization.

Let's build a simple service to understand how we can build internationalization in our APIs.

We would need to add a LocaleResolver and a message source to our Spring Boot application. The following code snippet should be included in Application.java:

    @Bean
    public LocaleResolver localeResolver() {
      SessionLocaleResolver sessionLocaleResolver = 
      new SessionLocaleResolver();
      sessionLocaleResolver.setDefaultLocale(Locale.US);
      return sessionLocaleResolver...
