I18n in Spring boot + Thymeleaf

Question

I\'m trying to make a multilanguage application using Spring boot and Thymeleaf.

I made few properties files to save the different messages but I\'m only able to display

Answer 1

Your application should extends WebMvcConfigurerAdapter

@SpringBootApplication
public class NerveNetApplication extends WebMvcConfigurerAdapter {

    public static void main(String[] args) {
        SpringApplication.run(NerveNetApplication.class, args);
    }

    @Bean
    public LocaleResolver localeResolver() {
        return new CookieLocaleResolver();
    }

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

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(localeChangeInterceptor());
    }
}

Then on browser you can switch language with param lang Example: http://localhost:1111/?lang=kh which messages_kh.properites will store the content of Khmer language.
