The release 3.0 of Spring Framework added the Spring Module OXM which supports the marshalling and unmarshalling of Java objects and XML documents.In this post, we will be using Spring OXM to take a Java object, convert it to a XML-format and save it in the hard-disk as an XML file containing information of that Java object. We will also cover how to retrieve back the serialized state of that XML file and reconstruct it back to it's original state as a Java object.
Sample of using Hibernate Annotations by reducing XML configuration files thus making it simpler to define required metadata directly into our Java code. When using annotations, we no longer need the additional mapping file (*.hbm.xml). The metadata for the ORM is specified in the individual classes.
