JAXB - Unmarshalling Example

Marshalling Example

File: com.ram.core.Person.java

 package com.ram.core;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public class Person {
 private String name;
 private int id;
 private int age;
 private String address;
 
 public String getName() {
  return name;

File: C:\Person.xml

  <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<person>
    <address>Richmond</address>
    <age>31</age>
    <id>1</id>
    <name>Ram</name>
</person>
  
  

File: com.ram.core.UnmarshallExample.java

package com.ram.core;

import java.io.File;

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

public class UnmarshallExample {
 public static void main(String[] args) {
  try{
   JAXBContext jaxbContext = JAXBContext.newInstance(Person.class);
   Unmarshaller unmarshall = jaxbContext.createUnmarshaller();
   
   File f = new File("C:\\Person.xml");
            Person person = (Person) unmarshall.unmarshal(f);
 
            System.out.println("Name = "+person.getName());
            System.out.println("Id = "+person.getId());
            System.out.println("Age = "+person.getAge());
            System.out.println("Address = "+person.getAddress());
   
   
  }catch(Exception e){
   System.out.println("Exception occurred while unmarshalling ..."+e);
  }
 }

}

 

Below is the output file that gets generated when the above program is executed
Name = Ram
Id = 1
Age = 31
Address = Richmond
