Overview
This example will build upon the lessons learned in the previous example (JAXB Customizations), and demonstrate how MOXy extensions can be used to further customize the XML output.
Using MOXy Extensions
Some of the MOXy extensions are available through EclipseLink annotations, others require programmatic changes to the underlying metadata. The EclipseLink annotation @XmlPath is used to specify path based mappings.
package example.gettingstarted; import java.util.ArrayList; import java.util.List; import javax.xml.bind.annotation.XmlRootElement; import javax.xml.bind.annotation.XmlType; import org.eclipse.persistence.oxm.annotations.XmlPath; @XmlRootElement @XmlType(propOrder={"name", "address", "phoneNumbers"}) public class Customer { private String name; private Address address; private List<PhoneNumber> phoneNumbers; public Customer() { phoneNumbers = new ArrayList<PhoneNumber>(); } @XmlPath("personal-info/name/text()") public String getName() { return name; } public void setName(String name) { this.name = name; } @XmlPath("contact-info/address") public Address getAddress() { return address; } public void setAddress(Address address) { this.address = address; } @XmlPath("contact-info/phone-number") public List<PhoneNumber> getPhoneNumbers() { return phoneNumbers; } public void setPhoneNumbers(List<PhoneNumber> phoneNumbers) { this.phoneNumbers = phoneNumbers; } }
Converting Objects to XML
The following code is used to convert the objects to XML. This is the same code from the previous example (JAXB Customizations).
package example.gettingstarted; import javax.xml.bind.JAXBContext; import javax.xml.bind.JAXBException; import javax.xml.bind.Marshaller; public class Demo { public static void main(String[] args) throws JAXBException { // Step 1 - Create the Domain Model Customer customer = new Customer(); customer.setName("Jane Doe"); Address address = new Address(); address.setStreet("123 Any Street"); address.setCity("My Town"); customer.setAddress(address); PhoneNumber workPhoneNumber = new PhoneNumber(); workPhoneNumber.setType("work"); workPhoneNumber.setValue("613-555-1111"); customer.getPhoneNumbers().add(workPhoneNumber); PhoneNumber cellPhoneNumber = new PhoneNumber(); cellPhoneNumber.setType("cell"); cellPhoneNumber.setValue("613-555-2222"); customer.getPhoneNumbers().add(cellPhoneNumber); // Step 2 - Convert the Domain Model to XML JAXBContext jaxbContext = JAXBContext.newInstance(Customer.class); Marshaller marshaller = jaxbContext.createMarshaller(); marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true); marshaller.marshal(customer, System.out); } }
XML Output
The following is the resulting XML.
<?xml version="1.0" encoding="UTF-8"?> <customer> <personal-info> <name>Jane Doe</name> </personal-info> <contact-info> <address> <city>My Town</city> <street>123 Any Street</street> </address> <phone-number type="work">613-555-1111</phone-number> <phone-number type="cell">613-555-2222</phone-number> </contact-info> </customer>
