GSON：预期为BEGIN_OBJECT，但为STRING

Question

我在尝试将JSON解组到对象中时遇到GSON错误。错误（ 应为BEGIN_OBJECT，但在第3行第22列处为STRING ）指向下面输入的第3行。

我是否相对于Bean正确映射了JSON？

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;
}

我输入的JSON看起来是这样的：

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

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

你可以创建一个类只是为了封装你BusinessPartnerCreate，但它是清洁反序列化容器的jsonObject使用

 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);

并且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;

（和类似的邮政编码）
