Dropwizard /Jersey Changing query parameters using a filter -

is there way change existing query parameters using jersey filter. have clients passing in id's this

/v1/path?id=1,2,3

what them show list in resource class //resource class

public list<something> getfilteredlist(@queryparam("id") list<string> ids) {// 

right now, ids list contains 1 string 1,2,3. apply filter , change comma separated query parameters multivalued parameters resource method gets list instead.

is @ possible? tried filter query params given jersey's

containerrequestcontext.geturiinfo().getqueryparameters()  

is immutable.

what's way solve problem?

the best way can think of create wrapper class list. makes easier take advantage of specified functionality of jersey. can see mean @ passing custom type query parameter.

for example

public class idfilter {     private list<string> ids = new arraylist<>();     public list<string> getids() { return ids; }      public static idfilter valueof(string param) {         idfilter filter = new idfilter();         (string id: param.split(",") {             filter.getids().add(id);         }     } }  getfilteredlist(@queryparam("id") idfilter ids) { 

we don't need else. having static valueof enough jersey know how parse query string.
