Class SessionLocaleResolver

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

All Implemented Interfaces:

LocaleResolver

public class SessionLocaleResolver

extends java.lang.Object

implements LocaleResolver

Implementation of LocaleResolver that uses a locale attribute in the user's session in case of a custom setting, with a fallback to the accept header locale. This is most appropriate if the application needs user sessions anyway.

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