Java에서 JSON-lib API를 사용하여 Bean을 XML로 변환하는 방법은 무엇입니까?

public String write(JSON json)

import net.sf.json.JSONObject; import net.sf.json.xml.XMLSerializer; public class ConvertBeanToXMLTest { public static void main(String[] args) { Student student = new Student("Sai", "Adithya", 25, "Pune"); JSONObject jsonObj = JSONObject.fromObject(student); System.out.println(jsonObj.toString(3)); //pretty print JSON XMLSerializer xmlSerializer = new XMLSerializer(); String xml = xmlSerializer.write(jsonObj); System.out.println(xml); } public static class Student { private String firstName, lastName, address; public int age; public Student(String firstName, String lastName, int age, String address) { super(); this.firstName = firstName; this.lastName = lastName; this.age = age; this.address = address; } public String getFirstName() { return firstName; } public String getLastName() { return lastName; } public int getAge() { return age; } public String getAddress() { return address; } } }

{ "firstName": "Sai", "lastName": "Adithya", "address": "Pune", "age": 25 }   
Pune
 25 Sai Adithya
