将 GET 请求的响应保存为类对象 [关闭]

Question

我正在尝试使用对 API 的 GET 请求来获取一些日期。我想要做的是将此请求的响应保存为我事先创建的 Java 类。这是我的课：

import java.util.List;
    
public class Person {
    String name = null;
    List<Siblings> siblings  = null;
}

以下是我发送 GET 请求并以字符串形式读取数据的方式：

try {
    URL url = new URL("someURL");
    
    HttpURLConnection connection = (HttpURLConnection) url.openConnection();
    connection.setRequestMethod("GET");
    connection.setDoOutput(true);
    connection.setRequestProperty("Authorization", "Bearer " + "bearerString");
    connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");

    InputStream content = (InputStream) connection.getInputStream();
    BufferedReader in = new BufferedReader(new InputStreamReader(content));
    String line;
    while ((line = in.readLine()) != null) {
        System.out.println(line);
    }
} catch (Exception e) {
    e.printStackTrace();
}

如何将 Http 请求的响应保存在一个类对象中，而不仅仅是一个字符串？

你可以使用Jacksonhttps://github.com/FasterXML/jackson

例子：

ObjectMapper mapper = new ObjectMapper();
Person person = mapper.readValue(json, Person.class);
