When using Spring MVC for REST, how do you enable Jackson to pretty-print rendered JSON?

Question

While developing REST services using Spring MVC, I would like render JSON \'pretty printed\' in development but normal (reduced whitespace) in production.

Based on baeldung this could be a nice idea using java 8:

@Override
public void extendMessageConverters(List> converters) {

    Optional> converterFound;
       converterFound = converters.stream().filter(c -> c instanceof AbstractJackson2HttpMessageConverter).findFirst();

    if (converterFound.isPresent()) {
        final AbstractJackson2HttpMessageConverter converter;
        converter = (AbstractJackson2HttpMessageConverter) converterFound.get();
        converter.getObjectMapper().enable(SerializationFeature.INDENT_OUTPUT);
        converter.getObjectMapper().enable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);
    }
}
