Can't map a Query String parameters to my JavaBean (using Spring 4 and Datatables)

Question

I\'m really stuck into trying to map my QueryString parameters into my Spring JavaBean Command object here, and I couldn\'t find an answer to my question so far.

Ok, so I ended up fixing this issue with slightly modifying the parameters sent to the server, to transform the two 3D array of columns into a 2D array. So:

columns[0][search][value]=myvalue
columns[0][search][regex]=false

ended up being:

columns[0][searchValue]=myvalue
columns[0][searchRegex]=false

This is how to do that in Databables:

$('#produtosTable').DataTable({
    serverSide: true,
    ajax: {
        "url": "produtos-source",
        "data": function(data) {
            planify(data);  
        } 
    }
});

function planify(data) {
    for (var i = 0; i < data.columns.length; i++) {
        column = data.columns[i];
        column.searchRegex = column.search.regex;
        column.searchValue = column.search.value;
        delete(column.search);
    }
}

This way I can receive those properties in my Model object using this field:

private List> columns;

---

Just for reference, here is my Controller:

@RequestMapping(value = "/produtos-source", method = RequestMethod.GET)
@ResponseStatus(HttpStatus.OK)
@ResponseBody
public ProdutoTable dataTableRequest(@ModelAttribute DataTableCriterias criterias) {
    ProdutoTable produtoTable = produtosService.findProdutos();
    produtoTable.setDraw(criterias.getDraw());
    return produtoTable;
}

and here is final my DataTableCriterias @ModelAttriute:

public class DataTableCriterias {
    private int draw;
    private int start;
    private int length;

    private Map search;

    private List> columns;

    private List> order;

    public enum SearchCriterias {
        value,
        regex
    }
    public enum OrderCriterias {
        column,
        dir
    }
    public enum ColumnCriterias {
        data,
        name,
        searchable,
        orderable,
        searchValue,
        searchRegex
    }
