All Implemented Interfaces:
LocaleResolver
```
public class AcceptHeaderLocaleResolver
extends Object
implements LocaleResolver
```
LocaleResolver 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 setLocale, since the accept header can only be changed through changing the client's locale settings.
