Sending list in JSON request

Question

I am sending few 'fields' and 'lists' in JSON to Spring MVC Controller as below:

    var data = {
        'message' : 'Text data',
        '**listOfIds**' : '350234983, 378350950',

        'synchronizerToken' : formTokenId

};

$.ajax({
        url : 'testURL.do',
        type : 'post',
        data : data,
        cache : false,
        dataType : 'json',

        success : function (jsonResponse) {},

        error : function (error) {}
});

In Spring MVC controller the URL handler looks like this:

    @RequestMapping(value = "/testURL.do", method = RequestMethod.POST)
public ModelAndView executeTest( ListData listData) {
        ModelAndView    modelAndView    = null;
        JsonResponse    jsonResponse    = null;

        modelAndView    = executeTransaction(listData);
        } 

        return modelAndView;
    }


ListData.java

public class ListData{
    private String          message;
    private List<String>    **listOfIds** = new ArrayList<String>();   

//getter/setters

The issue is listOfIds is not being returned as list. It is returned as single string '350234983, 378350950'

Can anyone suggest if anything is wrong here or is there any better way to receive list in JSON response?

Answer 1

Make listOfIds an array of strings instead of a single string.

'listOfIds' : ['350234983', '378350950'],
