XStream Parser : XML & JSON

• Xstream parser is used to convert java POJO to xml or json and vice-versa.
• The main benefit is we can use different parsers for different file like Stax parser.

Project Structure :-  

Student Pojo Class :-

package com.sandeep.example.value.objects;

public class Student {
 
 private String name;
 
 private int marks;
 
 private  String course;

 public String getName() {
  return name;
 }

 public void setName(String name) {
  this.name = name;
 }

 public int getMarks() {
  return marks;
 }

 public void setMarks(int marks) {
  this.marks = marks;
 }

 public String getCourse() {
  return course;
 }

 public void setCourse(String course) {
  this.course = course;
 }
 

}

Student Data Service:-

package com.sandeep.example.value.services;

import java.util.ArrayList;
import java.util.List;

import com.sandeep.example.value.objects.Student;

public class StudentService {

 
 
 public static List getData(){
  
  List listOfStudent =new ArrayList();
  Student student1 = new Student();
  Student student2 = new Student();
  Student student3 = new Student();
  Student student4 = new Student();
  
  student1.setName("Sandeep");
  student2.setName("Surabhi");
  student3.setName("Sumanta");
  student4.setName("Sangeeta");
  
  student1.setCourse("M.Tech");
  student2.setCourse("MSc.");
  student3.setCourse("B.Tech");
  student4.setCourse("B.E.");
  
  student1.setMarks(95);
  student2.setMarks(97);
  student3.setMarks(98);
  student4.setMarks(45);
  
  listOfStudent.add(student1);
  listOfStudent.add(student2);
  listOfStudent.add(student3);
  listOfStudent.add(student4);
  
  return listOfStudent;
  
  
 }
}

Test the Parser:-

package com.sandeep.example.xstream;

import java.util.List;

import com.sandeep.example.value.objects.Student;
import com.sandeep.example.value.services.StudentService;
import com.thoughtworks.xstream.XStream;
import com.thoughtworks.xstream.io.json.JsonHierarchicalStreamDriver;
import com.thoughtworks.xstream.io.xml.StaxDriver;

public class TestMyXstreamParser {

 
 public static void main(String[] args) {

  //to xml conversion with alias
  List listOfStudent=StudentService.getData();
  XStream xstream = new XStream(new StaxDriver());
  xstream.alias("student",com.sandeep.example.value.objects.Student.class);
  String xml=xstream.toXML(listOfStudent);
  System.out.println(xml);
  
  //to json conversion with alias
  XStream xstreamjson = new XStream(new JsonHierarchicalStreamDriver());
  xstreamjson.setMode(XStream.NO_REFERENCES);
  xstreamjson.alias("student", com.sandeep.example.value.objects.Student.class);
        System.out.println(xstreamjson.toXML(listOfStudent));

  
  
 }

}
