Spring, thimeleaf and localized strings

Question

I'm new to using Spring and Thymeleaf, and I can't figure out where to put the .properties localization files. I have this Bean:

@Bean public MessageSource messageSource() { ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource(); messageSource.setBasenames("classpath:messages/messages", "classpath:messages/validation"); // if true, the key of the message will be displayed if the key is not // found, instead of throwing a NoSuchMessageException messageSource.setUseCodeAsDefaultMessage(false); messageSource.setDefaultEncoding("UTF-8"); // # -1 : never reload, 0 always reload messageSource.setCacheSeconds(0); return messageSource; } 

Inside login.html:

  <p th:text="#{messages.hello}">Welcome to our site!</p> 

Inside messages_en.properties :

  messages.hello=Apparently messages work 

My project structure:

I tried to create a folder inside WEB-INF called messages, but apparently I do not understand what is correct. Any ideas?

Edit: Updated question with message related code.

Answer 1

I know that he is old. But I was looking for a solution and got this post.

I found the solution myself, while others with the same problem can get it here. So this is how I solved it:

Introduce MessageSource into SpringTemplateEngineBean.

 @Bean public SpringTemplateEngine templateEngine(MessageSource messageSource, ServletContextTemplateResolver templateResolver) { SpringTemplateEngine engine = new SpringTemplateEngine(); engine.setTemplateResolver(templateResolver); engine.setMessageSource(messageSource); return engine; } 

Now Thimeleaf knows about your MessageSource and evaluates your expressions.

The base name in this XML stands for the prefix of .properties that contain different translations.

Let's say that you need two languages: English ( en ) and Polish ( pl ). All you have to do is set Basename to messages as follows:

 messageSource.setBasename("classpath:messages"); 

and then put the two messages_en and messages_pl files in your classpath ( WEB-INF should be enough, although consider using the src/main/resources directory).

This is a basic example that should be easily adapted to your case.

Answer 3

You must expose the Thymeleaf SpringTemplateEngine as a bean so that Spring MessageSource your MessageSource into it:

 @Bean public SpringTemplateEngine templateEngine() { final SpringTemplateEngine templateEngine = new SpringTemplateEngine(); templateEngine.setTemplateResolver(templateResolver()); return templateEngine; } 

For MessageSource configuration MessageSource see Michał Rybak's answer .
