I’m trying to do the internationalization of templat using

  • Thymeleaf 3.0
  • Spring 4.2.3
  • JSF 2.2

Which is sent along with an email.

#{i18N.descriptionPortal}

When you print in the email html it looks like this

??i18N.descriptionPortal_pt_BR??

the Thymeleaf do not know of the i18n that works in JSF pages, some hint of how to parametrize it?

Configuration for i18n and Thymeleaf

@Configuration(value = "webapp")
@EnableWebMvc
@EnableTransactionManagement
@EnableScheduling
@ApplicationScoped
public class AppInitializer extends WebMvcConfigurerAdapter implements WebApplicationInitializer, ApplicationContextAware
{


    private ApplicationContext          applicationContext;

    @Override
    public void configureDefaultServletHandling(final DefaultServletHandlerConfigurer configurer)
    {
        configurer.enable();
    }

    @Override
    public void onStartup(final ServletContext servletContext) throws ServletException
    {
        final AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
        ctx.register(Config.class);
        //definido o listener do spring para o contexto
        servletContext.addListener(new RequestContextListener());
        servletContext.addListener(new ContextLoaderListener(ctx));
        ctx.setServletContext(servletContext);
    }


    @Bean
    @Autowired
    public ViewResolver viewResolver(@Qualifier("templateEngine") final TemplateEngine templateEngine)
    {
        final ThymeleafViewResolver resolver = new ThymeleafViewResolver();
        resolver.setTemplateEngine(templateEngine);
        resolver.setCharacterEncoding("UTF-8");
        return resolver;
    }


    @Bean(name = "templateEngine")
    public TemplateEngine templateEngine() throws Exception
    {
        final SpringTemplateEngine engine = new SpringTemplateEngine();
        engine.setEnableSpringELCompiler(true);
        engine.setTemplateResolver(templateResolver());
        engine.afterPropertiesSet();
        return engine;
    }

    private ITemplateResolver templateResolver()
    {
        final SpringResourceTemplateResolver resolver = new SpringResourceTemplateResolver();
        resolver.setApplicationContext(applicationContext);
        resolver.setPrefix("/WEB-INF/classes/mail/");
        resolver.setTemplateMode(TemplateMode.HTML);
        return resolver;
    }

    @Bean(name = "msg")
    public MessageSource messageSource()
    {
        final ResourceBundleMessageSource message = new ResourceBundleMessageSource();
        message.setBasenames("messages/messages", "messages/build");
        message.setDefaultEncoding("UTF-8");
        message.setUseCodeAsDefaultMessage(true);
        return message;
    }

    @Bean
    public LocaleResolver localeResolver()
    {
        final SessionLocaleResolver localeResolver = new SessionLocaleResolver();
        localeResolver.setDefaultLocale(new Locale("pt", "BR"));
        return localeResolver;
    }

    @Bean
    public LocaleChangeInterceptor localeChangeInterceptor() {
        final LocaleChangeInterceptor lci = new LocaleChangeInterceptor();
        lci.setParamName("msg");
        return lci;
    }   
}

These are the forms I tried to use in the template, I’ve made several settings and nothing.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns:th="http://www.thymeleaf.org" th:with="lang=${#locale.language}" th:lang="${msg}">
<body>
    <table class="tableCenter">
        <tr>
            <th colspan="2">
                <h2>
                    <span th:utext="#{msg.descriptionPortal}" />
                    <span th:utext="#{descriptionPortal}" />
                </h2>
            </th>
        </tr>
        .
        .
        .

This is the result in the email received

??msg.descriptionPortal_pt_BR?? ?? descriptionPortal_pt_BR??

This is the error when I try to use the i18n key in . xhtml

I’ve done many other configurations but practically always arrive at the same result

This return of Themeleaf is that it did not find the text in pt_BR for the variable "descriptionPortal".

Take a look at this answer Using i18n

You basically need to create a messages_pt_BR.properties file within Resources/i18n/ and have the variable there

descriptionPortal = Descrição do Portal em português

Add the parameter to the tag you are using, for example:

<p th:text="${descriptionPortal}"></p>

  • I looked at what you suggested, tried to adjust compliant tips and nothing, updated with parts of the source and error I’m having, the question.

  • Inside the messages/messages folder, is there the messages_pt_BR file? Did you test with messages_en_US.properties? You have to see which site Thymeleaf is recognizing.

  • Another thread, as you set pt_BR by default, try using the message.properties. file Your browser/ OS has locales like pt_BR?

  • Yes there are the files, messages_pt_BR.properties and messages_en_US.properties.

  • As you set with default = pt_BR, there must be message.properties

The whole problem was generated as follows:

  • Themeleaf injects into your source somewhere, it only reads the Messagesource interface;
  • That must have the bean messageSource
  • How JSF needs java.util.Resourcebundle
  • Creates a Singleton Resourcebundle object
  • In this case called i18n

    @Component("i18N")
    @Scope("singleton")
    public class SysResourceBundleRead extends ResourceBundle implements Serializable, MessageSource{
     ..
     ..
     ..
    }
  • See the object implementing Messagesource
  • Now in the configuration I get the object
  • @Qualifier("i18n") 
    
@Bean(name = { "messageSource"})
@Autowired
public MessageSource messageSource(@Qualifier("i18N") final SysResourceBundleRead resourceBundleRead)
{
    return resourceBundleRead;
}
  • So whoever uses this name uses the same object thinking it is messageSource, default

The jsf configuration integrating Spring looks like this

<application>
    <el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
    <el-resolver>com.sys.resolver.SysLocaleController</el-resolver>
    <resource-bundle>
        <base-name>messages.build</base-name>
        <var>build</var>
    </resource-bundle>
    <resource-bundle>
        <display-name>I18N</display-name>
        <base-name>messages.messages</base-name>
        <var>i18N</var>
    </resource-bundle>
    <locale-config>
        <default-locale>pt_BR</default-locale>
        <supported-locale>en_US</supported-locale>
        <supported-locale>pt_BR</supported-locale>
    </locale-config>
    <message-bundle>messages.messages</message-bundle>

</application>

To use in JSF uses so:

#{i18N.descriptionPortal}

To use in themeleaf uses so:

#{descriptionPortal}

To use in Spring uses so:

@Qualifier(name = { "messageSource"})
@Autowired
public MessageSource messageSource;

Or 

@Qualifier(name = { "i18N"})
@Autowired
public SysResourceBundleRead i18N;

Both are the same object, but they use different methods to read the keys, so you need to adjust your class to have this synchronization.
