Interface LocaleResolver

All Known Implementing Classes:

AcceptHeaderLocaleResolver, CookieLocaleResolver, FixedLocaleResolver, SessionLocaleResolver

public interface LocaleResolver

Interface for web-based locale resolution strategies that allows for both locale resolution via the request and locale modification via request and response.

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.
