Hi,
We are getting LazyInitializationExceptions when marshalling an object graph
read from a DB by Hibernate to XML.
We deliberately do not load certain parts of the graph because we do not ever
want to see that data. Unfortunately
when JiBX tried to iterator over the Set (which is really a Hibernate
PersistentSet) Hibernate tries to load the uninitialized data
but the Hibernate session has long since been closed.
I would like to create a global custom marshhaller that would skip the
collection if it uninitialized. This appeared
easy to do so I wrote:
public class PersistentSetMapper {
public void marshal(Object obj, IMarshallingContext ctx)
throws JiBXException {
PersistentSet pset = (PersistentSet) obj;
if (!pset.wasInitialized()) {
return;
}
for (Object ele : pset) {
if (ele instanceof IMarshallable) {
((IMarshallable) ele).marshal(ctx);
}
}
}
}
And added it at the top of my binding definition:
<mapping class="org.hibernate.collection.PersistentSet" name="pset"
marshaller="PersistentSetMapper"/>
I have not been able to try this because I get an error saying you can't call
out a custom
marhshaller unless you also have a custom unmarshaller.
Q: Am I on the right track here? Is there a better, easier way of doing this?
Q: How can I create a custom unmarshaller that just does exactly what the
standard marshaller
would have done for the collection?
Thanks, - Jon
