Spring OXM - Test JAXB2

Create a main class OXMApplication.java with marshaller and unmarshaller objects. The objective of this class is to marshall a student object to student.xml using marshaller object and then unmarshall the student.xml to student object using unmarshaller object.

Example

OXMApplication.java

package com.tutorialspoint.oxm;

import java.io.FileInputStream;
import java.io.FileWriter;
import java.io.IOException;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.oxm.Marshaller;
import org.springframework.oxm.Unmarshaller;
import org.springframework.oxm.XmlMappingException;
import com.tutorialspoint.oxm.model.Student;

public class OXMApplication {
   public static void main(String[] args) {
      ApplicationContext context = new ClassPathXmlApplicationContext("applicationcontext.xml");  
      Marshaller marshaller = (Marshaller)context.getBean("jaxbMarshaller");
      Unmarshaller unmarshaller = (Unmarshaller)context.getBean("jaxbMarshaller");

      // create student object
      Student student = new Student();
      student.setAge(14);
      student.setName("Soniya");

      try {
         marshaller.marshal(student, new StreamResult(new FileWriter("student.xml")));  
         System.out.println("Student marshalled successfully.");  
         FileInputStream is =  new FileInputStream("student.xml");
         Student student1 = (Student)unmarshaller.unmarshal(new StreamSource(is));
         System.out.println("Age: " + student1.getAge() + ", Name: " + student1.getName());
      } catch(IOException | XmlMappingException ex) {
         ex.printStackTrace();
      }
   }
}

Output

Right click in the content area of the file in eclipse and then select Run as java application and verify the output.
