java - Retrieving query parameters in order in JAX-RS UriInfo -

in jax-rs need iterate (arbitrary) given query parameters in request... in original order in uri!

if inject @context uriinfo uriinfo can use uriinfo.getqueryparameters() multivaluedmap of query parameters, grouped query parameter name. if care original order of query parameters? there way iterate name/value pairs? or must extract them manually uriinfo.getrequesturi()?

if i'm stuck manual extraction, there standard or well-maintained , updated library can use doing this?

custom solution apache httpclient library:

public void process(@context uriinfo uriinfo) {     string querystring = uriinfo.getrequesturi().getquery()     //todo: extract charset content-type header, if present     list<namevaluepair> queryparams = urlencodedutils.parse(querystring, "utf-8")     for(namevaluepair param : queryparams) {         //do need     } }
