如何为两个数组 Json 创建 Java 类

Question

我正在尝试为以下 Json

创建 Java Pojo 类

https://www.reddit.com/r/MurderedByWords/comments/ervfco/trying_to_relate_to_their_viewers/.json

我只是想从 JSON 中提取评论，作者 created_utc。我无法弄清楚，因为它有两个数组。

谁能帮我制作一下？

 0 0O bject;
 1 1 Object;


 // Getter Methods 

 public 0 get0() {

您问题中 URL 返回的

JSON 是一个包含 2 个对象的数组。

您可以使用 jsonschema2pojo 等在线工具生成 POJO 类（select 源类型为 JSON）。

然后您可以使用任何流行的 json 库，如 Jackson 或 GSON 将 json 转换为 POJO。

根 POJO 类似于

public class Root{
    private List<Item> items;
}

public class Item {
    private Data data;

    private String kind;
}

JSON结构：
