Answer 1

You can remove the StringHttpMessageConverter which is registered before the jackson converter, - like mentioned in the comment.

/**
 * Unregister the default {@link StringHttpMessageConverter} as we want
 * Strings to be handled by the JSON converter.
 *
 * Our MappingJackson2HttpMessageConverter will deal with strings.
 *
 * @param converters
 *            List of already configured converters
 */
@Override
public void extendMessageConverters(List> converters) {
    converters.removeIf(converter -> converter instanceof StringHttpMessageConverter);
}
