如何将JSON HTTP响应的一部分作为POJO检索

import com.google.gson.Gson;

// 定义POJO类
class ResponseData {
    private String name;
    private int age;
    
    // 构造函数
    public ResponseData(String name, int age) {
        this.name = name;
        this.age = age;
    }
    
    // Getter方法
    public String getName() {
        return name;
    }
    
    public int getAge() {
        return age;
    }
}

public class Main {
    public static void main(String[] args) {
        // 模拟JSON响应
        String jsonResponse = "{\"name\":\"John\", \"age\":30, \"city\":\"New York\"}";
        
        // 解析JSON响应
        Gson gson = new Gson();
        ResponseData responseData = gson.fromJson(jsonResponse, ResponseData.class);
        
        // 检索POJO对象
        String name = responseData.getName();
        int age = responseData.getAge();
        
        // 打印结果
        System.out.println("Name: " + name);
        System.out.println("Age: " + age);
    }
}
