java - Elegant way to get Locale in Spring Controller -

-

i'm looking cleaner way (in spring 3.2) current locale explicitly calling localecontextholder.getlocale() @ start of each controller method. has compatible java annotation, i'm not using xml config. here's i'm doing currently.

@controller public class wifecontroller {     @autowired     private messagesource msgsrc;      @requestmapping(value = "/wife/mood")     public string readwife(model model, @requestparam("whatimdoing") string iam) {         locale loc = localecontextholder.getlocale();         if(iam.equals("playingxbox")) {             model.addattribute( "statustitle", msgsrc.getmessage("mood.angry", null, loc) );             model.addattribute( "statusdetail", msgsrc.getmessage("mood.angry.xboxdiatribe", null, loc) );         }         return "moodresult";     } }

in spring 3.2 reference docs, section 17.3.3, supported method argument types:

the following supported method arguments:

  • request or response objects (servlet api). choose specific request or response type, example servletrequest or httpservletrequest.

    (...)

  • java.util.locale current request locale, determined specific locale resolver available, in effect, configured localeresolver in servlet environment.

so you'd need receive instance of locale argument in every method:

@requestmapping(value = "/wife/mood") public string readwife(model model, @requestparam("whatimdoing") string iam, locale loc) {     if (iam.equals("playingxbox")) {         model.addattribute("statustitle", msgsrc.getmessage("mood.angry", null, loc));         model.addattribute("statusdetail", msgsrc.getmessage("mood.angry.xboxdiatribe", null, loc));     }     return "moodresult"; }
