- org.springframework.web.server.i18n.AcceptHeaderLocaleContextResolver

All Implemented Interfaces:
LocaleContextResolver
```
public class AcceptHeaderLocaleContextResolver
extends Object
implements LocaleContextResolver
```
LocaleContextResolver implementation that simply uses the primary locale specified in the "Accept-Language" header of the HTTP request (that is, the locale sent by the client browser, normally that of the client's OS).
Note: Does not support setLocaleContext(org.springframework.web.server.ServerWebExchange, org.springframework.context.i18n.LocaleContext), since the accept header can only be changed through changing the client's locale settings.
Since:
5.0

- Method Detail
  - setSupportedLocales
```
public void setSupportedLocales(List<Locale> locales)
```
    Configure supported locales to check against the requested locales determined via HttpHeaders.getAcceptLanguageAsLocales().

```
public List<Locale> getSupportedLocales()
```
    Return the configured list of supported locales.

    Parameters:
    defaultLocale - the default locale to use
  - getDefaultLocale
```
@Nullable
public Locale getDefaultLocale()
```
    The configured default locale, if any.

  - resolveLocaleContext
```
public LocaleContext resolveLocaleContext(ServerWebExchange exchange)
```
    Description copied from interface: LocaleContextResolver
    Resolve the current locale context via the given exchange.
    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.
    Specified by:
    resolveLocaleContext in interface LocaleContextResolver
    Parameters:
    exchange - current server exchange
    Returns:
    the current locale context (never null)
  - setLocaleContext
```
public void setLocaleContext(ServerWebExchange exchange,
                             @Nullable
                             LocaleContext locale)
```
    Description copied from interface: LocaleContextResolver
    Set the current locale context to the given one, potentially including a locale with associated time zone information.
    Specified by:
    setLocaleContext in interface LocaleContextResolver
    Parameters:
    exchange - current server exchange
    locale - the new locale context, or null to clear the locale
