Spring and JAXB Integration

  • Spring provides integration with JAXB (Java Architecture for XML Binding) to simplify the process of marshaling and unmarshaling XML data. JAXB allows you to convert Java objects to XML and vice versa. Here’s how to integrate Spring with JAXB:

Step 1: Include JAXB Dependencies

  • Ensure that you have the JAXB dependencies in your project. If you are using Maven, you can add the following dependency to your pom.xml:
    <!-- Use the latest version -->


Step 2: Configure JAXB Marshaller and Unmarshaller

  • In your Spring configuration (XML or Java-based), configure the Jaxb2Marshaller bean for both marshaling (converting Java objects to XML) and unmarshaling (converting XML to Java objects).
					<bean id="jaxbMarshaller" 
    value="com.example.model" /> 

<!-- For unmarshalling -->
<bean id="jaxbUnmarshaller" 
    <property name="contextPath" 
    .model" />

public class AppConfig {

   public Jaxb2Marshallerjaxb2Marshaller() 
Jaxb2Marshaller marshaller = 
new Jaxb2Marshaller();
// Specifythe package with your 
JAXB-annotated classes
      return marshaller;

public Jaxb2Marshaller 
jaxb2Unmarshaller() {
Jaxb2Marshaller unmarshaller = 
new Jaxb2Marshaller();
return unmarshaller;


Step 3: Use JAXB in Your Application

  • With the Jaxb2Marshaller beans configured, you can use them to marshal and unmarshal XML data in your application.
private Jaxb2Marshaller jaxbMarshaller;

public String marshalObjectToXml
(Object object) {
    StringWriter writer = 
    new StringWriter();
    new StreamResult(writer));
    return writer.toString();

private Jaxb2Marshaller jaxbUnmarshaller;

public Object unmarshalXmlToObject
(String xml) {
    StringReader reader
    = new StringReader(xml);
    return jaxbUnmarshaller.unmarsha
    l(new StreamSource(reader));

  • Ensure that your Java classes are annotated with JAXB annotations like @XmlRootElement, @XmlElement, etc., to specify how the XML should be generated and parsed.
public class MyObject {
    private String name;

    // Getter and Setter for 'name'

  • By integrating Spring with JAXB, you can easily work with XML data in your Spring-based applications, whether it’s for reading XML configuration files, handling XML-based web services, or other XML-related tasks.
