All Implemented Interfaces:

LocaleContextResolver, LocaleResolver

public class FixedLocaleResolver
extends AbstractLocaleContextResolver

LocaleResolver implementation that always returns a fixed default locale and optionally time zone. Default is the current JVM's default locale.

Note: Does not support setLocale(Context), as the fixed locale and time zone cannot be changed.

1.1

Constructor Details

FixedLocaleResolver

public FixedLocaleResolver()

Create a default FixedLocaleResolver, exposing a configured default locale (or the JVM's default locale as fallback).

See Also:

• AbstractLocaleResolver.setDefaultLocale(java.util.Locale)
• AbstractLocaleContextResolver.setDefaultTimeZone(java.util.TimeZone)

FixedLocaleResolver

public FixedLocaleResolver(Locale locale)

Create a FixedLocaleResolver that exposes the given locale.

Parameters:

locale - the locale to expose

FixedLocaleResolver

public FixedLocaleResolver(Locale locale,
 TimeZone timeZone)

Create a FixedLocaleResolver that exposes the given locale and time zone.

Parameters:

locale - the locale to expose

timeZone - the time zone to expose

Method Details

resolveLocale

public Locale resolveLocale(HttpServletRequest request)

Description copied from interface: LocaleResolver

Resolve the current locale via the given request. Can return a default locale as fallback in any case.

Specified by:

resolveLocale in interface LocaleResolver

Overrides:

resolveLocale in class AbstractLocaleContextResolver

Parameters:

request - the request to resolve the locale for

Returns:

the current locale (never null)

resolveLocaleContext

public LocaleContext resolveLocaleContext(HttpServletRequest request)

Description copied from interface: LocaleContextResolver

Resolve the current locale context via the given request.

This is primarily intended for framework-level processing; consider using RequestContextUtils or RequestContext for application-level access to the current locale and/or time zone.

The returned context may be a TimeZoneAwareLocaleContext, containing a locale with associated time zone information. Simply apply an instanceof check and downcast accordingly.

Custom resolver implementations may also return extra settings in the returned context, which again can be accessed through downcasting.

Parameters:

request - the request to resolve the locale context for

Returns:

the current locale context (never null

• RequestContextUtils.getLocale(jakarta.servlet.http.HttpServletRequest)
• RequestContextUtils.getTimeZone(jakarta.servlet.http.HttpServletRequest)

setLocaleContext

public void setLocaleContext(HttpServletRequest request,
 @Nullable
 HttpServletResponse response,
 @Nullable
 LocaleContext localeContext)

Description copied from interface: LocaleContextResolver

Set the current locale context to the given one, potentially including a locale with associated time zone information.

Parameters:

request - the request to be used for locale modification

response - the response to be used for locale modification

localeContext - the new locale context, or null to clear the locale
