如何将动态json转换为java类？

import com.fasterxml.jackson.databind.ObjectMapper;

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

        try {
            ObjectMapper objectMapper = new ObjectMapper();
            Person person = objectMapper.readValue(json, Person.class);
            System.out.println(person.getName());
            System.out.println(person.getAge());
            System.out.println(person.getCity());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    static class Person {
        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;
        }
    }
}
