替换GSON中的密钥 [英] Replace a key in GSON

问题描述

我是GSON的新手.我有一个JSON对象(作为字符串)-

I'm new to GSON. I have a JSON object (As a String) -

{
"name" : "myName",
"city" : "myCity"
}

我将其解析如下-

JsonParser parser = new JsonParser();
JsonObject json_result = (JsonObject)parser.parse(#TheAboveMentionedStringGoesHere);

现在，我想将键name替换为其他内容，例如firstName，以使生成的JSON对象为-

Now I want to replace the key name with something else ,say, firstName so that the resulting JSON object is -

{
"firstName" : "myName",
"city" : "myCity"
}

这可能吗?我该如何实现?

Is this possible? How do I achieve this?

推荐答案

如果您使用com.google.code.gson:gson:2.+ Google GSON第三方库，然后根据其. 因此，您的模型类可能如下所示:

If you use com.google.code.gson:gson:2.+ Google GSON third party library, and then according to it's documentations, you can use @SerializedName("commits_url")in the model class or POJO. So your model class might be like below :

public class Example {

    @SerializedName("first_name")
    String name;

    @SerializedName("city")
    String city;
}

，以及当您希望将其用作:

and also when you want use it as :

Gist gist = new Gson().fromJson("{
"firstName" : "myName",
"city" : "myCity"
}", Gist.class);

最后，如果您认为需要使用自定义的Serialiazer和Deserializer，请阅读
