How to display messages in Thymeleaf and Spring Boot?

Question

I created a Spring Boot web application that uses Thymeleaf as the template engine. I configured the MessageSource to look for messages in a subfolder:

@Bean public MessageSource messageSource() {     final ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();      messageSource.setBasename("i18n/messages");     messageSource.setFallbackToSystemLocale(false);     messageSource.setCacheSeconds(0);      return messageSource; } 

In this folder I created the file messages_de.properties with the content ticket.type.BUG=Fehler. In my template I try to display the text like this:

<p th:text="#{ticket.type.BUG}">BUG</p> 

But when the page is rendered, I get the following:

<p>??ticket.type.BUG_de_DE??</p> 

What am I missing? Do I have to configure any additional beans?

P.S.:

On the 'server side' I am able to obtain the message using MessageSource#getMessage("ticket.type.BUG", null, Locale.GERMANY).

Answer 1

Because I am using Spring Boot, the MessageSource is configured with a MessageSourceAutoConfiguration. These settings can be easily changed in the application.properties file. In my case I had to add the following to this file:

spring.messages.basename=i18n/messages 

Answer 2

And add this to your application.properties file

#messages spring.messages.basename=i18n/messages 

and store the file n the correct folder as specified above.

you don't need messageSource bean
