This example application demonstrates implementing internationalization and localization in a Vaadin Spring Boot project. Locales supported are English, Finnish and French.

Among the classes under the com.vaadin.example package

• Application.java is responsible for running the application
• GreetService.java supplies localized greetings
• MainView.java is the main view, and an entry point for the application
• ServiceInitListener.java customises start-up process by setting a locale for the application
• SimpleI18NProvider.java is a simple implementation of a I18NProvider

Resource bundles with the name labelsbundle, which contain the actual translations, are located under the /resources folder.

Import the project to the IDE of your choosing as a Maven project.

Run the application using mvn spring-boot:run or by running the Application class directly from your IDE.

Open http:https://localhost:8080/ in your browser.

If you want to run the application locally in the production mode, run mvn spring-boot:run -Pproduction.
