## Class AcceptHeaderLocaleResolver

- java.lang.Object
- - org.springframework.web.servlet.i18n.AcceptHeaderLocaleResolver

- All Implemented Interfaces:
    LocaleResolver

      public class AcceptHeaderLocaleResolver
      extends Object
      implements LocaleResolver

  Implementation of LocaleResolver 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 `setLocale`, since the accept header can only be changed through changing the client's locale settings.
