## org.springframework.context.i18n
Class LocaleContextHolder

    java.lang.Object
      org.springframework.context.i18n.LocaleContextHolder

    public abstract class LocaleContextHolder

extends Object

Simple holder class that associates a LocaleContext instance with the current thread. The LocaleContext will be inherited by any child threads spawned by the current thread.

Used as a central holder for the current Locale in Spring, wherever necessary: for example, in MessageSourceAccessor. DispatcherServlet automatically exposes its current Locale here. Other applications can expose theirs too, to make classes like MessageSourceAccessor automatically use that Locale.

Since:
  1.2
