java.lang.Object org.springframework.web.servlet.i18n.AbstractLocaleResolver org.springframework.web.servlet.i18n.SessionLocaleResolver
public class SessionLocaleResolver
Implementation of LocaleResolver that uses a locale attribute in the user's session in case of a custom setting, with a fallback to the specified default locale or the request's accept-header locale.
This is most appropriate if the application needs user sessions anyway, that is, when the HttpSession does not have to be created for the locale.
Custom controllers can override the user's locale by calling
setLocale
, e.g. responding to a locale change request.
