Gson - 使用两个不同的键读取值 [英] Gson - Read a value with two different keys

问题描述

在我的 Android 项目中，我有两种类型的响应，其中 响应除了两个键外都是相同的.

In my Android project I have two types of response where both response are identical except two keys.

响应 1

{"fullName":"William Sherlock Scott Holmes","address":"221B Baker Street, London, England, UK","downloads":642,"rating":3,"repos":["https://link1","https://link2","https://link3"]}

响应 2

{"name":"Sherlock","city":"London","downloads":642,"rating":3,"repos":["https://link1","https://link2","https://link3"]}

如果您看到响应，只有两个键名发生了变化 fullName/name 和 address/city

If you see the responses only two key names are changing fullName/name and address/city

我不想为其他响应再创建一个 pojo.我的问题是:是否可以只使用一个 Pojo 来读取两个回复?

I don't want to create one more pojo for other response. My question is: is it possible to use only one Pojo to read both responses?

public class AccountInfo {
    private String name;
    private String city;
    //other objects

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }
    //other setters and getters
}

任何帮助将不胜感激...

Any help will be appreciated...

推荐答案

您可以使用 @SerializedName 注释:

@SerializedName(value = "name", alternate = {"fullName"})
private String name;
@SerializedName(value = "city", alternate = {"address"})
private String city;

然后可以将任一命名元素放入这样注释的成员中.

Either named element can then be placed into the members that are annotated like this.

更新:@SerializedName 在 2.4 版

UPDATED : @SerializedName alternate names when deserializing is added in Version 2.4
