SessionLocaleResolver

<init>

org.springframework.web.servlet.LocaleResolver implementation 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, i.e. when the HttpSession does not have to be created just for storing the user's locale. The session may optionally contain an associated time zone attribute as well; alternatively, you may specify a default time zone.

Custom controllers can override the user's locale and time zone by calling #setLocale(Context) on the resolver, e.g. responding to a locale change request. As a more convenient alternative, consider using org.springframework.web.servlet.support.RequestContext#changeLocale.

In contrast to CookieLocaleResolver, this strategy stores locally chosen locale settings in the Servlet container's HttpSession. As a consequence, those settings are just temporary for each session and therefore lost when each session terminates.

Note that there is no direct relationship with external session management mechanisms such as the "Spring Session" project. This LocaleResolver will simply evaluate and modify corresponding HttpSession attributes against the current HttpServletRequest.

LOCALE_SESSION_ATTRIBUTE_NAME

Name of the session attribute that holds the Locale. Only used internally by this implementation.

Use RequestContext(Utils).getLocale() to retrieve the current locale in controllers or views.

TIME_ZONE_SESSION_ATTRIBUTE_NAME

Name of the session attribute that holds the TimeZone. Only used internally by this implementation.

Use RequestContext(Utils).getTimeZone() to retrieve the current time zone in controllers or views.

resolveLocale

resolveLocaleContext

setLocaleAttributeName

Specify the name of the corresponding attribute in the HttpSession, holding the current Locale value.

The default is an internal #LOCALE_SESSION_ATTRIBUTE_NAME.

setLocaleContext

setTimeZoneAttributeName

Specify the name of the corresponding attribute in the HttpSession, holding the current TimeZone value.

The default is an internal #TIME_ZONE_SESSION_ATTRIBUTE_NAME.

getDefaultTimeZone

Return the default TimeZone that this resolver is supposed to fall back to, if any.

setDefaultTimeZone

Set a default TimeZone that this resolver will return if no other time zone found.
