GSON预期为BEGIN_OBJECT，但实际为BEGIN_ARRAY
GSON预期为BEGIN_OBJECT，但实际为BEGIN_ARRAY

我有下面的JSON和模型类，如何使用GSOn反序列化这个JSON我得到了一个异常，就像下面的snippet.how的“Expected BEGIN_OBJECT but was BEGIN_ARRAY”，以形成下面的JSON数据的Model calss
Gson gson = new Gson();
Referrals referrals = gson.fromJson(response.toString(),Referrals.class);
public class Referrals {
private List<Referral> referrals;
}
public class Referral implements Serializable{
private String referral_id;
private String notes;
private String attachment;
private String patient_consent;
private String date_of_referral;
private String is_read;
private String type;
}
{
"referrals": [
{
"referral_id": "2",
"notes": "test issue",
"attachment": "test.jpg",
"patient_consent": "Yes",
"date_of_referral": "2014-11-26 15:14:45",
"is_read": "0",
"type": "sender"
},
{
"referral_id": "1",
"notes": "ok",
"attachment": null,
"patient_consent": "Yes",
"date_of_referral": "2014-11-26 11:52:43",
"is_read": "0",
"type": "sender"
}
],
"response": "1"

尝试更改此设置
private List<Referral> referrals;至
private ArrayList<Referral> referrals;还要使Referrals类成为Serializable类

创建一个名为ReferralHandler的类：
public class ReferralHandler implements Serializable {
@SerializedName("referrals")
private ArrayList<Referral> referrals = new ArrayList<Referral>();
public ArrayList<Referral> getReferrals() {
return referrals;
}然后创建一个名为Referral的类：
public class Referral implements Serializable {
@SerializedName("referral_id")
private String referral_id;
@SerializedName("notes")
private String notes;
@SerializedName("attachment")
private String attachment;
@SerializedName("patient_consent")
private String patient_consent;
@SerializedName("date_of_referral")
private String date_of_referral;
@SerializedName("is_read")
private String is_read;
@SerializedName("type")
private String type;
// setters and getters
}最后，要进行解析，您必须编写：
ReferralHandler referralsObject = gson.fromJson(response.toString(), ReferralHandler.class);
ArrayList<Referral> referrals = referralsObject.getReferrals();页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
