java - How to parse received json data in action -

-

i sending json array data jsp action class have included struts2-json-plugin. want parse receive arraylist elements. code

in jsp:

$.ajax({         url: "updatenotification",         datatype: "json",         data: {ids: json.stringify(ids)},         success: function(data) {             alert("success " + data.st);         }     })

in action:

public class test extends actionsupport {     arraylist<string> ids = new arraylist<string>();          public arraylist<string> getids() {             return ids;         }          public void setids(arraylist<string> ids) {             this.ids = ids;         }          public string updatenotification() {                  system.out.println("id " + getids());                     (string : getids()) {                         system.out.println("data " + a);                     }              }       }

on running showing data 

id [["25","27","28"]]   data ["25","27","28"]

how can 1 data 1 array element in action.

edit trying data 

ids(0)=25; ids(1)=27; ids(2)=28;

json stringify method returns array of values in json format ["25","27","28"]. convert list need remove [ or ] characters submit csv values. because csv values converted list. try

data: {ids: json.stringify(ids).replace(/[\[\]]/g,'')},
