如何根据 json 数组解析或创建 pojo？

Question

我想解析以下 JSON 并使用我的代码（如字符串分词器）正常工作，但我想使用任何标准方法（例如 GSON.. 等）或如何为其创建 POJO 进行解析，using this，请问如何解决这个问题，谢谢

JSON

[
   [
      "106639",
      "jonni",
      "assistant director",
      "1"
   ],
   [
      "106639",
      "maikel",
      "operator and publisher",
      "1"
   ]
]

您没有自定义 json 对象。它是数组中的简单字符串数组，因此您应该使用 ArrayList> class 类型，如下所示。

科特林：

val model = Gson().fromJson(jsonString, ArrayList<ArrayList<String>>()::class.java)

Java:

ArrayList<ArrayList<String>> model = new Gson().fromJson(jsonString, new TypeToken<ArrayList<ArrayList<String>>>() {}.getType());

TypeToken

public class TypeToken<T> extends Object

Represents a generic type T.Java doesn't yet provide a way to represent generic types, so this class does. Forces clients to create a subclass of this class which enables retrieval the type information even at runtime. For example, to create a type literal for List<String>, you can create an empty anonymous inner class:

TypeToken<List<String>> list = new TypeToken<List<String>>() {};

This syntax cannot be used to create type literals that have wildcard parameters, such as Class<?> or List<? extends CharSequence>.
