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:

Answer 1

The way I resolved the i18n messaging was to define the MessagesSource bean like you. Additionally I had to override the getValidator() method of the WebMvcConfigurerAdapter.

@Override
public Validator getValidator() {
    LocalValidatorFactoryBean validator = new LocalValidatorFactoryBean();
    validator.setValidationMessageSource( messageSource() );
    return validator;
}

After this, it worked for me.
