java - GSON库中自定义读写方法

Question

嗨，我有以下 JSON


{
“名称”:“testapp2”，
"type":"网络",
"packageName":"test2.com",
"secretKey":{"0987654321","91287465827"},
"otpExpiry":"1800",
"senderId":"验证",
"otp长度":"4",
"requestPerIp":"500",
"signature":"#OTP是您的验证码"
}

我正在编写我的自定义 JSON 读取器和编写器，这是我覆盖 GSON TypeAdapter 类的代码，这是我的代码。我正在 try catch 我的 JSON 对象并将其转换为我的自定义模型类...基本上我想解析嵌套 json 对象

public Application read(JsonReader reader) throws IOException {
Application application = new Application();
String secKey=null;
reader.beginObject();
while (reader.hasNext()) {
  String name = reader.nextName();
  switch (name) {
    case "type":
      ApplicationType type = new ApplicationType(reader.nextString());
      application.setType(type);
      break;
    case "packageName":
      application.setPackageName(reader.nextString());
      break;
    case "otpExpiry":
      application.setOtpExpiry(reader.nextInt());
      break;
    case "name":
      application.setName(reader.nextString());
      break;
    case "senderId":
      application.setSenderId(reader.nextString());
      break;
    case "otpLength":
      application.setOtpLength(reader.nextInt());
      break;
    case "requestPerIp":
      application.setRequestPerIp(reader.nextLong());
      break;
    case "secretKey":
      reader.beginArray();
      while (reader.hasNext())
       secKey+=reader.nextString();
      application.setSecretKey(secKey);
      break;
    case "signature":
      application.setSignature(reader.nextString());
      break;
    case "sendOTPInResponse":
      application.setSendOTPInResponse(reader.nextInt());
      break;
    default:
      reader.skipValue();
      break;
  }
}
reader.endObject();
return application;

此方法无法解析..请帮忙...

请使用 GSON 库，它提供从 JSONString 到模型的转换

您需要创建模型并传递 jsonString

在此创建 ModelCalss

public class Store  {
public String StoreId;
public String StoreDisplayLink;
public String StoreAddress;

}

GSON 库会将您的 JSONString 映射到您的模型

 private Store getStoreModel(String jsonStore) {

    Type type = new TypeToken<Store>() {
    }.getType();
    Store store = new Gson().fromJson(jsonStore, type);
    return store;

}
