```
public class CookieLocaleResolver
extends CookieGenerator
implements LocaleContextResolver
```
LocaleResolver implementation that uses a cookie sent back to the user in case of a custom setting, with a fallback to the specified default locale or the request's accept-header locale.
This is particularly useful for stateless applications without user sessions. The cookie may optionally contain an associated time zone value 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 RequestContext.changeLocale(java.util.Locale).

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

public LocaleContext resolveLocaleContext(HttpServletRequest request)
```
    从接口复制的说明: 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.
    指定者:
    resolveLocaleContext 在接口中 LocaleContextResolver
    参数:
    request - the request to resolve the locale context for
    返回:

    返回:
    a String representation for the given locale
