I done serverpaging, how can I get the parameters on the call of url?

i am using spring framework, everytime the page and pagesize are null.

@RequestMapping(value = "/list", method = RequestMethod.POST, produces = "application/json; charset=UTF-8")
    @ResponseBody
    public String listJSON(@RequestParam(value = "page", required = false) Integer page, @RequestParam(value = "pageSize", required = false) Integer pageSize) throws Exception {
        Iterator<Obj> iterator;
        if (page != null && pageSize != null) {
            PageRequest pageReq = new PageRequest(page, pageSize);
            iterator = repo.findAll(pageReq).iterator();
        } else {
            PageRequest pageReq = new PageRequest(0, 5);
            iterator = repo.findAll(pageReq).iterator();
        }

<kendo:grid name="grid" selectable="single" pageable="true" groupable="true" sortable="true" filterable="true">
                        <kendo:grid-columns>
                            <kendo:grid-column title="Name" field="name" />
                            <kendo:grid-column title="Quantity" field="quantity" />
                            <kendo:grid-column title="Dimensions" field="dimensions" />
                        </kendo:grid-columns>
                        <kendo:dataSource pageSize="5" serverPaging="true">
                            <kendo:dataSource-schema data="assets" total="total">
                                <kendo:dataSource-schema-model>
                                    <kendo:dataSource-schema-model-fields>
                                        <kendo:dataSource-schema-model-field name="name" type="string" />
                                        <kendo:dataSource-schema-model-field name="quantity" type="number" />
                                        <kendo:dataSource-schema-model-field name="dimensions" type="number" />
                                    </kendo:dataSource-schema-model-fields>
                                </kendo:dataSource-schema-model>
                            </kendo:dataSource-schema>
                            <kendo:dataSource-transport>
                                <kendo:dataSource-transport-read contentType="application/json" type="POST" url="${transportReadUrl}"/>
                            </kendo:dataSource-transport>

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
public class DataSourceRequest {

    private int page;
    private int pageSize;
    private int take;
    private int skip;
    private HashMap<String, Object> data;

    public DataSourceRequest() {
        data = new HashMap<String, Object>();
    }

    public HashMap<String, Object> getData() {
        return data;
    }

    public int getPage() {
        return page;
    }

    public int getPageSize() {
        return pageSize;
    }

    public int getTake() {
        return take;
    }

    public int getSkip() {
        return skip;
    }
}

I use this in my controller

@RequestMapping(value = "/list", method = RequestMethod.POST, produces = "application/json; charset=UTF-8")
    @ResponseBody
    //public String listAssetsJSON(@RequestParam(value = "page", required = false) Integer page, @RequestParam(value = "pageSize", required = false) Integer pageSize) throws Exception {
      public String listAssetsJSON(@RequestBody DataSourceRequest request) throws Exception
      {
        // get the records

        System.out.println("ttttt "+request.getPage()+" "+request.getPageSize());

I still get 0 0
