Spring OXM – Quick Guide ”; Previous Next Spring OXM – Overview The Spring Framework provides Object/XML or O/X mapping using global marshaller/unmarshaller interfaces and allows to switch O/X mapping frameworks easily. This process of converting an object to XML is called XML Marshalling/Serialization and conversion from XML to object is called XML Demarshalling/Deserialization. Spring framework provides a Marshaller and UnMarshaller interfaces where Marshaller interface is responsible to marshall an object to XML and UnMarshaller interface deserializes the xml to an object. Following are the key benefits of using Spring OXM framework. Easy Configuration − Using spring bean context factory, creation of marshaller/unmarshaller is quite easy and is configurable without worrying about O/X libraries structures like JAXB Context, JiBX binding factories etc. A marsaller/unmarshaller can be configured as any other bean. Consistent Interfacing − Marshaller and UnMarshaller are global interfaces. These interfaces provides an abstraction layer over other O/X mapping frameworks and allows to switch between them without changing the code or with little code change. Consistent Exception Handling − All underlying exceptions are mapped to a XmlMappingException as root exception. Thus developers need not to worry about underlying O/X mapping tool own exception hiearchy. Marshaller Marshaller is an interface with single method marshal. public interface Marshaller { /** * Marshals the object graph with the given root into the provided Result. */ void marshal(Object graph, Result result) throws XmlMappingException, IOException; } Where graph is any object to be marshalled and result is a tagging interface to represent the XML output. Following are the available types − javax.xml.transform.dom.DOMResult − Represents org.w3c.dom.Node. javax.xml.transform.sax.SAXResult − Represents org.xml.sax.ContentHandler. javax.xml.transform.stream.StreamResult − Represents java.io.File, java.io.OutputStream, or java.io.Writer. UnMarshaller UnMarshaller is an interface with single method unmarshal. public interface UnMarshaller { /** * Unmarshals the given provided Source into an object graph. */ Object unmarshal(Source source) throws XmlMappingException, IOException; } Where source is a tagging interface to represent the XML input. Following are the available types − javax.xml.transform.dom.DOMSource − Represents org.w3c.dom.Node. javax.xml.transform.sax.SAXSource − Represents org.xml.sax.InputSource, and org.xml.sax.XMLReader. javax.xml.transform.stream.StreamSource − Represents java.io.File, java.io.InputStream, or java.io.Reader. Spring OXM – Environment Setup This chapter will guide you on how to prepare a development environment to start your work with Spring Framework. It will also teach you how to set up JDK, Maven and Eclipse on your machine before you set up Spring Framework − Setup Java Development Kit (JDK) You can download the latest version of SDK from Oracle”s Java site − Java SE Downloads. You will find instructions for installing JDK in downloaded files, follow the given instructions to install and configure the setup. Finally set PATH and JAVA_HOME environment variables to refer to the directory that contains java and javac, typically java_install_dir/bin and java_install_dir respectively. If you are running Windows and have installed the JDK in C:jdk-11.0.11, you would have to put the following line in your C:autoexec.bat file. set PATH=C:jdk-11.0.11;%PATH% set JAVA_HOME=C:jdk-11.0.11 Alternatively, on Windows NT/2000/XP, you will have to right-click on My Computer, select Properties → Advanced → Environment Variables. Then, you will have to update the PATH value and click the OK button. On Unix (Solaris, Linux, etc.), if the SDK is installed in /usr/local/jdk-11.0.11 and you use the C shell, you will have to put the following into your .cshrc file. setenv PATH /usr/local/jdk-11.0.11/bin:$PATH setenv JAVA_HOME /usr/local/jdk-11.0.11 Alternatively, if you use an Integrated Development Environment (IDE) like Borland JBuilder, Eclipse, IntelliJ IDEA, or Sun ONE Studio, you will have to compile and run a simple program to confirm that the IDE knows where you have installed Java. Otherwise, you will have to carry out a proper setup as given in the document of the IDE. Setup Eclipse IDE All the examples in this tutorial have been written using Eclipse IDE. So we would suggest you should have the latest version of Eclipse installed on your machine. To install Eclipse IDE, download the latest Eclipse binaries from www.eclipse.org/downloads. Once you download the installation, unpack the binary distribution into a convenient location. For example, in C:eclipse on Windows, or /usr/local/eclipse on Linux/Unix and finally set PATH variable appropriately. Eclipse can be started by executing the following commands on Windows machine, or you can simply double-click on eclipse.exe %C:eclipseeclipse.exe Eclipse can be started by executing the following commands on Unix (Solaris, Linux, etc.) machine − $/usr/local/eclipse/eclipse After a successful startup, if everything is fine then it should display the following result − Set Maven In this tutorial, we are using maven to run and build the spring based examples. Follow the Maven – Environment Setup to install maven. Spring OXM – Create Project Using eclipse, select File → New → Maven Project.
