Externalizing Text in Thymeleaf

Localization

1. Create files for your messages

   messages.properties
   messages_en.properties messages_fr.properties
   …

2. Write messages in this files like this

header.label.title=Title

3. Configure path to this files (in this case in folder D:/project/messages) in application properties like:

   messages.basename.path=D:/project/messages/messages

4. Configure MessageSource

   @Value(”${messages.basename.path}”) private String messagesBasename;

   @Bean public MessageSource messageSource() { ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource(); messageSource.setFallbackToSystemLocale(false); messageSource.setBasenames(“file:” + messagesBasename); return messageSource; }

5. Use messages on pages

<p th:text="#{header.label.title}">Title</p>

Localization messages with parameters

Write message in messages.properties

welcome.message=Hello, {0}!

Replace {0} with the user name inside thymeleaf tag

<h3 th:text="#{welcome.message(${some.variable})}">Hello, Placeholder</h3>
