为什么数据库的数据显示不了在kendo ui的grid编辑页面上

      <a class="offline-button" href="login.jsp">Back</a>

            <div id="example">
            <div id="grid"></div>

            <script>
                $(document).ready(function () {
                   var crudServiceBaseUrl = "",
                        dataSource = new kendo.data.DataSource({
                            transport: {
                                read:  {
                                    url: crudServiceBaseUrl + "",
                                    dataType: "json"                                                              
                                },
                                update: {
                                    url: crudServiceBaseUrl + "",
                                    dataType: "json"                          
                                },
                                destroy: {
                                    url: crudServiceBaseUrl + "",
                                    dataType: "json"

                                    }
                                }
                            },
                            batch: true,
                            pageSize: 15,
                            schema: {
                                model: {
                                    id: "book_id",
                                    fields: {

                                        book_price: { type: "double"},
                                        book_amount:{type:"amount"},
                                        book_time:{type:"date"},
                                    }
                                }
                            }
                        });

                    $("#grid").kendoGrid({
                        dataSource: dataSource,
                        pageable: true,
                        height: 550,
                        toolbar: ["create"],
                        columns: [
                            { field:"book_id", title: "图书编号" ,width: "120px"},
                            { field: "book_name", title:"图书名称",  width: "120px" },
                            { field: "book_sort", title:"分类", width: "120px" },
                            { field: "book_author", title:"作者", width: "120px" },
                            { field: "book_price", title:"价格", width: "120px" },
                            { field: "book_amount", title:"数量", width: "120px" },
                            { field: "book_time", title:"上架时间", width: "120px" },
                            { command: ["edit", "destroy"], title: "&nbsp;", width: "200px" }],
                        editable: "popup"
                    });
                });
            </script>
        </div> 
</body>
</html>

这个页面的url到底怎么写。。。。

html:

transport: {
            read: {
                url: BaseUrl + "/cin/ctrc/reporting/orgs/query",
                type: "POST",
                dataType: "json"
            }

controller:

@RequestMapping(value = "/cin/ctrc/reporting/orgs/query")

参考一下，我最近也被这个玩意搞得有点难受
ps:这是hap框架的（尴尬）
