Can I use a messages.yml file instead of messages.properties for message codes

Question

Can I use messages.yml in place of messages.properties to define internationalization of messages.

I tried it, it doesn't work, can anyone help what else needs to be done?

My resolver looks like this

@Bean
    public ResourceBundleMessageSource messageSource() {
        ResourceBundleMessageSource rs = new ResourceBundleMessageSource();
        rs.setBasename("i18n/messages");
        rs.setDefaultEncoding("UTF-8");
        rs.setUseCodeAsDefaultMessage(true);
        return rs;
    }

I have put messages.yml under resources/i18n/.
