@Provider @Produces({"application/xml","application/*+xml","text/xml","text/*+xml"}) @Consumes({"application/xml","application/*+xml","text/xml","text/*+xml"}) public class JAXBXmlTypeProvider extends AbstractJAXBProvider<Object>
A JAXB entity provider that handles classes without
XmlRootElement
annotation. Classes which have been generated by XJC will most likely not contain this annotation, In order for these classes to marshalled, they must be wrapped within aJAXBElement
instance. This is typically accomplished by invoking a method on the class which serves as theXmlRegistry
and is named ObjectFactory.This provider is selected when the class is annotated with an
XmlType
annotation and not anXmlRootElement
annotation.This provider simplifies this task by attempting to locate the
XmlRegistry
for the target class. By default, a JAXB implementation will create a class called ObjectFactory and is located in the same package as the target class. When this class is located, it will contain a "create" method that takes the object instance as a parameter. For example, of the target type is called "Contact", then the ObjectFactory class will have a method:public JAXBElement<Contact> createContact(Contact value);

findObjectFactory
public static Object findObjectFactory(Class<?> type)
Attempts to locateXmlRegistry
for the XML type. Usually, a class named ObjectFactory is located in the same package as the type we're trying to marshall. This method simply locates this class and instantiates it if found.- Parameters:
type
- type class- Returns:
- object factory instance
-
wrapInJAXBElement
public static JAXBElement<?> wrapInJAXBElement(Object t, Class<?> type)
If this object is managed by an XmlRegistry, this method will invoke the registry and wrap the object in a JAXBElement so that it can be marshalled.- Parameters:
t
- object to wraptype
- type class- Returns:
- jaxb element
