Java使用 gson 解析出现的错误

错误：Expected BEGIN_ARRAY but was BEGIN_OBJECT
Json数据是：
{"results":[
{"createdAt":"2016-11-05 13:10:21","matchU1":"K2","objectId":"37T5444G","state":false,"updatedAt":"2016-11-05 13:23:09"},
{"createdAt":"2016-11-05 13:10:36","matchU1":"12","objectId":"1pPvDDDE","state":false,"updatedAt":"2016-11-05 13:10:39"},
{"createdAt":"2016-11-05 13:10:52","matchU1":"1","objectId":"0nSfhhhn","state":false,"updatedAt":"2016-11-05 13:23:02"}]}
JavaBean是：
public class Results {
private String matchU1;
private String matchU2;
private Boolean match1;
private Boolean match2;
private Boolean state;
private String objectId;
get\set方法省略
｝
然后gson是：
Gson gson=new Gson();
List ps = gson.fromJson(str, new TypeToken>(){}.getType());
会报错 应该怎么修改？

应该是你的javaBean写错了

首先我不明白所报的错是什么错，如果是跟orm框架有关的那就是懒加载造成的。 一般来说对象转json不那么容易抛错的，只有json转对象出错较高，你要注意的是你的对象属性是否有标准的getter和setter方法。
