Class CookieLocaleResolver

java.lang.Object
  org.springframework.web.servlet.i18n.CookieLocaleResolver

All Implemented Interfaces:

LocaleResolver

public class CookieLocaleResolver

extends java.lang.Object

implements LocaleResolver

Implementation of LocaleResolver that uses a cookie sent back to the user in case of a custom setting, with a fallback to the accept header locale. This is especially useful for stateless applications without user sessions.

Custom controllers can thus override the user's locale by calling setLocale, e.g. responding to a certain locale change request.
