How to convert a Xml to Java Object using JAXB API and Annotations through a Java program?.

Program to demonstrate conversion of a Xml to Java Object using JAXB API and Annotations through a Java program

Steps to convert Xml to Object :

1. Creating a POJO class :

package com.hubberspot.examples;

import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public class Customer {
 
 private Integer id;
 private String firstName; 
 private String lastName;
 private String email;
 
 public Customer(){
  
 }

 public Integer getId() {
  return id;
 }
 @XmlAttribute
 public void setId(Integer id) {
  this.id = id;
 }

 @XmlElement
 public String getFirstName() {
  return firstName;
 }

 public void setFirstName(String firstName) {
  this.firstName = firstName;
 }

 @XmlElement
 public String getLastName() {
  return lastName;
 }

 public void setLastName(String lastName) {
  this.lastName = lastName;
 }

 @XmlElement
 public String getEmail() {
  return email;
 }

 public void setEmail(String email) {
  this.email = email;
 } 
}




2. Create a conversion class :

package com.hubberspot.examples;

import java.io.File;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Unmarshaller;

public class JAXBXmlToObject {
 
   public static void main(String[] args) {
  
      try {
 JAXBContext context = JAXBContext.newInstance(Customer.class);
   
 Unmarshaller unmarshaller = context.createUnmarshaller();
   
 Customer customer = (Customer) unmarshaller.unmarshal(
    new File("Customer.xml"));
   
 System.out.println("Customer Id : " 
                     + customer.getId());
   
 System.out.println("Customer FirstName : " 
                     + customer.getFirstName());
  
 System.out.println("Customer LastName : " 
                     + customer.getLastName());
   
 System.out.println("Customer Email : " 
                     + customer.getEmail());
   
       } 
       catch (JAXBException e) {
   
      e.printStackTrace();
  
       }

  }

}



3. Input of the program - XML file as "Customer.xml"

























4. Output of the program :
