淘宝客开发过程遇到问题：
//开始调用淘宝API接口
TaobaoClient client = new DefaultTaobaoClient(url, appkey, appSecret);
TaobaokeItemsGetRequest req=new TaobaokeItemsGetRequest();
req.setFields("num_iid,title,nick,pic_url,price,click_url,commission,commission_rate,commission_num,commission_volume,shop_click_url,seller_credit_score,item_location,volume");
//返回数据
TaobaokeItemsGetResponse response = client.execute(req);
List list = response.getTaobaokeItems();
System.out.println(list.size());
Pageinfo newpage =new Pageinfo(defaultCurpage, pageno, pagesize, list); //生成Page
//生成json数据
String listJson = JSON.toJSONString(newpage, true);
System.out.println(listJson);
错误代码如下：
