I try to do exactly what is descripted in this question with MOXy. But i have some different behavior but the result is the same. It doesn't work.
I use @XmlElements and for each concret class I added a @XmlElement with name and type. For all classes without an adapter it works perfect but not for the class with the PolyAdapter.
In my case the adapter will be called to marshal the object. But all it writes is an entry like this into the xml file.
<?xml version="1.0" encoding="UTF-8"?>
<fooContainer>
<poly PolyName="PolyN$1">ABCBCD</poly>
<cPlexPoly>moxy.CPlexPoly$CPlexPolyAdapter$CCPWrapper@480bdb19</cPlexPoly>
</fooContainer>
And the unmarshaller won't be called at all.
I tested MOXy 2.5.0 and the current RC3 2.5.1 in both cases the results are the same. I also enabled the debug output and there are no warnings or error.
Or maybe there is another way to get this working
Update 1: Providing model
I created a small example showing my problem with MOXy 2.5.0
Interface:
@XmlRootElement
public interface Foo {
public List<String> getCoordinates();
}
Class without XmlAdapter:
@XmlRootElement(name="poly")
public class Poly implements Foo {
@XmlAttribute
String PolyName = "PolyN$1";
@XmlAnyElement
private List<String> coordinates = new LinkedList<>();
@Override
public List<String> getCoordinates() {
return coordinates;
}
public void addCoordinate( final String poly ) {
coordinates.add( poly );
}
}
Class with XmlAdapter:
@XmlJavaTypeAdapter(CPlexPolyAdapter.class)
public class CPlexPoly implements Foo {
private Map<String, String> values = new HashMap<>();
@Override
public List<String> getCoordinates() {
return new ArrayList<>(values.values());
}
public void addCoordinate( final String poly ) {
values.put( Integer.toString( poly.hashCode()), poly );
}
public List<String> getKeys() {
return new ArrayList<>(values.keySet());
}
public static class CPlexPolyAdapter extends XmlAdapter<CCPWrapper, CPlexPoly> {
@XmlRootElement(name="wrapper")
public static class CCPWrapper {
@XmlAnyElement
List<String> keys = new ArrayList<>();
@XmlAnyElement
List<String> values = new ArrayList<>();
}
@Override
public CPlexPoly unmarshal(CCPWrapper v) throws Exception {
// Won't be called.
return null;
}
@Override
public CCPWrapper marshal(CPlexPoly v) throws Exception {
if( v == null ) {
return null;
}
CCPWrapper wrapper = new CCPWrapper();
wrapper.values.addAll( v.getCoordinates() );
wrapper.keys.addAll( v.getKeys() );
return wrapper;
}
}
}
Simple container class:
@XmlRootElement(name="fooContainer")
public class FooContainer {
@XmlElements({
@XmlElement(name = "poly", type = Poly.class),
@XmlElement(name = "cPlexPoly", type = CPlexPoly.class)
})
public List<Foo> container = new LinkedList<>();
}
Main:
public class Main {
public static void main(String[] args) {
FooContainer fc = new FooContainer();
Poly poly = new Poly();
poly.addCoordinate("ABC");
poly.addCoordinate("BCD");
CPlexPoly cpoly = new CPlexPoly();
cpoly.addCoordinate("XYZ");
cpoly.addCoordinate("WXY");
fc.container.add( poly );
fc.container.add( cpoly );
/* Marshall */
JAXBContext context;
try {
context = JAXBContext.newInstance( FooContainer.class );
Marshaller marshaller = context.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
marshaller.marshal( fc, new FileWriter("fc.xml") );
}
catch (JAXBException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
/* UnMarshall */
}
}
I also updated the result i described above. Thx.
Update 2: Simplified Wrapper
Even with this simple wrapper containing nothing more than an attribute, nothing changes.
@XmlJavaTypeAdapter(CPlexPolyAdapter.class)
public class CPlexPoly implements Foo {
private Map<String, String> values = new HashMap<>();
@Override
public List<String> getCoordinates() {
return new ArrayList<>(values.values());
}
public void addCoordinate( final String poly ) {
values.put( Integer.toString( poly.hashCode()), poly );
}
public List<String> getKeys() {
return new ArrayList<>(values.keySet());
}
public static class CPlexPolyAdapter extends XmlAdapter<CCPWrapper, CPlexPoly> {
@XmlRootElement(name="wrapper")
public static class CCPWrapper {
@XmlAttribute
String test = "test";
}
@Override
public CPlexPoly unmarshal(CCPWrapper v) throws Exception {
// Won't be called.
return null;
}
@Override
public CCPWrapper marshal(CPlexPoly v) throws Exception {
if( v == null ) {
return null;
}
CCPWrapper wrapper = new CCPWrapper();
return wrapper;
}
}
}
So if someone has any idea what is wrong it would be very helpful. Thanks Christian
