如何使用JSON动态创建POJO？

import com.fasterxml.jackson.databind.ObjectMapper;

public class DynamicPOJOExample {
    public static void main(String[] args) {
        String json = "{\"name\":\"John\", \"age\":30, \"city\":\"New York\"}";

        try {
            ObjectMapper objectMapper = new ObjectMapper();
            MyPOJO myPOJO = objectMapper.readValue(json, MyPOJO.class);

            System.out.println("Name: " + myPOJO.getName());
            System.out.println("Age: " + myPOJO.getAge());
            System.out.println("City: " + myPOJO.getCity());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

class MyPOJO {
    private String name;
    private int age;
    private String city;

    // Getters and setters

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }
}
