public interface LocaleResolver
This interface allows for implementations based on request, session,
cookies, etc. The default implementation is
AcceptHeaderLocaleResolver
,
simply using the request's locale provided by the respective HTTP header.
Use RequestContext.getLocale()
to retrieve the current locale in controllers or views, independent
of the actual resolution strategy.
Note: As of Spring 4.0, there is an extended strategy interface
called LocaleContextResolver
, allowing for resolution of
a LocaleContext
object,
potentially including associated time zone information. Spring's
provided resolver implementations implement the extended
LocaleContextResolver
interface wherever appropriate.
