Unmarshalling JAXB collection when using IDResolver failing because IDResolver Object as target type
I have this problem trying to unmarshall json from rest webservice (cxf). I'm using JAXB and EclipseLink.
The entity is mapped like that:
@Entity
@Table(name = "service_pkg_service", schema = "MD")
@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class ServicePkgService extends DatabaseModel implements java.io.Serializable {
@Transient
@XmlIDREF
private Set<ChannelPkgService> channelPkgServices = new HashSet<ChannelPkgService>();
}
@Entity
@Table(name = "channel_pkg_service", schema = "MD")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement
public class ChannelPkgService extends DatabaseModel implements java.io.Serializable{
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "CHANNEL_PKG_ID")
@XmlID
@XmlAttribute
private String id;
}
I have a class extending IDResolver, so I can generate an entity based on its ID.
public class EntityIDResolver extends IDResolver{
@Override
public void bind(String id, Object obj) throws SAXException {
}
@SuppressWarnings({ "rawtypes", "unchecked" })
@Override
public Callable<?> resolve(final String id, Class targetType) throws SAXException {
}
}
开发者_如何学Go
I have problem unmarshalling json like this "channelPkgService": [1,2,3], the class of targetType is java.lang.Object
I read this https://github.com/javaee/jaxb-v2/issues/546 , and created a wrapper to handle this.
public class ChannelPkgServiceWrapper extends HashSet<ChannelPkgService>{
}
Sinse I have a lot of these cases and I don't want to create a lot of wrappers, is there a more generic way to handle that?
Forget the used versions:
- cxf.version:2.3.6
- eclipselink:2.3.0
- jaxb-impl-2.1.13.jar (jar containing Lister.class that is doing the actual work for getting the correct type.)
@XmlIDREF
is used by JAXB to map intra-document references. Each object referenced by ID must also appear nested somewhere in the XML or JSON document:

If you are looking to marshal an object as its ID, then you will want to use an XmlAdapter
. Check out my answer to a similar question:
- Serialize a JAXB object via its ID?
Also note that JAXB is a specification (JSR-222), and EclipseLink contains the MOXy implementation (I'm the MOXy tech lead). This means you could eliminate jaxb-impl-2.1.13.jar from your dependencies:
