public abstract class AbstractCookieValueMethodArgumentResolver extends AbstractNamedValueMethodArgumentResolver
@CookieValue
. Subclasses extract the cookie value from the request.
An @CookieValue
is a named value that is resolved from a cookie.
It has a required flag and a default value to fall back on when the cookie
does not exist.
A WebDataBinder
may be invoked to apply type conversion to the
resolved cookie value.
