Moshi使用不同的密钥解析json

class User {
    @Json(name = "first_name")
    String firstName;
}

class UserAdapter extends JsonAdapter<User> {
    @Override
    public User fromJson(JsonReader reader) throws IOException {
        User user = new User();
        reader.beginObject();
        while (reader.hasNext()) {
            String name = reader.nextName();
            if (name.equals("first_name")) {
                user.setFirstName(reader.nextString());
            } else {
                reader.skipValue();
            }
        }
        reader.endObject();
        return user;
    }

    @Override
    public void toJson(JsonWriter writer, User value) throws IOException {
        writer.beginObject();
        writer.name("first_name").value(value.getFirstName());
        writer.endObject();
    }
}

Moshi moshi = new Moshi.Builder()
    .add(new UserAdapter())
    .build();

JsonAdapter<User> userAdapter = moshi.adapter(User.class);
User user = userAdapter.fromJson(json);
