jsp传给java属性，java生成json串，方便以后取出来

前台代码

$.ajax({
        url : '<%=basePath%>userorderother/canUpdateCust.do',
        type : 'POST',
        data: {'kdcompany':kdcompany, 'kdcardid':kdcardid, 'odid':odid},
        async : false,
        success : function(data) {
            location.reload();
        }
    });
