GSON:预计BEGIN_OBJECT但是STRING

我在尝试将JSON解组为对象时遇到GSON错误。错误(预期BEGIN_OBJECT但在第3行第22列STRING )指向下面输入的第3行。

我没有正确映射关于Bean的JSON吗?

import javax.xml.bind.JAXBElement;

public class BusinessPartnerCreate {
    protected JAXBElement<String> partnerType;
    protected Person person;
    protected Company company;
    protected String email;
    protected String phone;
    protected AddressData addressData;
    protected AddressClean addressClean;
    protected String city;
    protected String state;
    protected String zipCode;
    protected JAXBElement<String> externalId;
}

我的输入JSON看起来是这样的:

{
    "business-partner-create": {
        "partner-type": "1",
        "person": {
            "firstName": "Dirk",
            "lastName": "Wintermill",
            "title": ""
        },
        "email": "kirk@yahoo.com",
        "phone": "219-385-2946",
        "addressClean": {
            "house-number": "10218",
            "street-name": "Park",
            "street-abbr": "Rd"
        },
        "city": "Somerset",
        "state": "NJ",
        "zip-code": "01955"
    }
}

不,您没有正确映射,因为您的json对象不是BusinessPartnerCreate,它包含BusinessPartnerCreate

您可以创建一个类来封装您的BusinessPartnerCreate,但使用

将容器反序列化为jsonObject会更加清晰
 JsonParser parser = new JsonParser();
 JsonObject obj = parser.parse(json).getAsJsonObject();

然后使用

解析有趣的内容
BusinessPartnerCreate bpc = gson.fromJson(obj.get("business-partner-create"), BusinessPartnerCreate.class);

我建议您添加注释以确保partnerType字段的正确映射:

   @SerializedName "partner-type"
   protected JAXBElement<String> partnerType;

(和邮政编码类似)
