Spring with Xstream Example

Xstream is a library to serialize objects to xml and vice-versa without requirement of any mapping file. Notice that castor requires an mapping file.

XStreamMarshaller class provides facility to marshal objects into xml and vice-versa.

Example of Spring and Xstream Integration (Marshalling Java Object into XML)

You need to create following files for marshalling java object into XML using Spring with Xstream:

Employee.java
applicationContext.xml
Client.java

Required Jar files

To run this example, you need to load:

Spring Core jar files
Spring Web jar files
xstream-1.3.jar

download all the jar files for spring including core, web, aop, mvc, j2ee, remoting, oxm, jdbc, orm etc.

download xstream-1.3.jar

Employee.java

If defines three properties id, name and salary with setters and getters.

 package com.tutoraspire; public class Employee { private int id; private String name; private float salary;  public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public float getSalary() { return salary; } public void setSalary(float salary) { this.salary = salary; } } 

applicationContext.xml

It defines a bean xstreamMarshallerBean where Employee class is bound with the OXM framework.

 <?xml version=”1.0″ encoding=”UTF-8″?> <beans xmlns=”http://www.springframework.org/schema/beans” xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance” xsi:schemaLocation=”http://www.springframework.org/schema/beans  http://www.springframework.org/schema/beans/spring-beans-3.0.xsd”>  <bean id=”xstreamMarshallerBean” class=”org.springframework.oxm.xstream.XStreamMarshaller”> <property name=”annotatedClasses” value=”com.tutoraspire.Employee”></property> </bean> </beans>  

Client.java

It gets the instance of Marshaller from the applicationContext.xml file and calls the marshal method.

 package com.tutoraspire; import java.io.FileWriter; import java.io.IOException; import javax.xml.transform.stream.StreamResult; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import org.springframework.oxm.Marshaller;  public class Client{  public static void main(String[] args)throws IOException{   ApplicationContext context = new ClassPathXmlApplicationContext(“applicationContext.xml”);   Marshaller marshaller = (Marshaller)context.getBean(“xstreamMarshallerBean”);    Employee employee=new Employee();   employee.setId(101);   employee.setName(“tutor aspire”);   employee.setSalary(100000);    marshaller.marshal(employee, new StreamResult(new FileWriter(“employee.xml”)));      System.out.println(“XML Created Sucessfully”);  } } 

Output of the example

employee.xml

 <com.tutoraspire.Employee> <id>101</id> <name>tutor aspire</name> <salary>100000.0</salary> </com.tutoraspire.Employee>
