Re: [5.4] hibernate events
Great! Note, you could reduce the verbosity by getting rid of the
interface, NOT registering a service and using @Autobuild
Ie:
@Startup
public static void initHibernateEventListener(@Autobuild
HibernateInitializerImpl hi) {
hi.initialize();
}
Re: [5.4] hibernate events
Thanks Lance, got it working.
public interface HibernateInitializer {
public void initialize();
}
public class HibernateInitializerImpl implements HibernateInitializer {
@Inject
SolrIndexer solrIndexer;
@Inject
private HibernateSessionSource hss;
@Override
public void initialize() {
EventListenerRegistry registry = ((SessionFactoryImpl)
hss.getSessionFactory()).getServiceRegistry().getService(
EventListenerRegistry.class);
registry.getEventListenerGroup(EventType.PERSIST).appendListener(new
MyPersistEventListener(solrIndexer));
}
}
in AppModule
public static void bind(ServiceBinder binder) {
//...
binder.bind(HibernateInitializer.class, HibernateInitializerImpl.class);
}
@Startup
public static void initHibernateEventListener(Logger logger,
HibernateInitializer hi) {
hi.initialize();
}
Not sure if this the best way to go, but it works :).

Can you add the listener in a @Startup method or some @EagerLoad service?

Re: [5.4] hibernate events
Thanks Thiago, sometimes its to easy :).
Now I've got everything injected, but my
EventListenerHibernateConfigurer still don't work:
java.lang.RuntimeException: Exception constructing service
'ValueEncoderSource': Error invoking service contribution method
org.apache.tapestry5.hibernate.modules.HibernateModule.contributeValueEncoderSource(MappedConfiguration,
boolean, HibernateSessionSource, Session, TypeCoercer, PropertyAccess,
LoggerSource): Exception constructing service 'HibernateSessionSource': Error

org.apache.tapestry5.internal.hibernate.HibernateSessionSourceImpl(org.slf4j.Logger,java.util.List):
Exception constructing service 'HibernateSessionSource': Construction of
service 'HibernateSessionSource' has failed due to recursion: the service
depends on itself in some way. Please check
org.apache.tapestry5.internal.hibernate.HibernateSessionSourceImpl(Logger,
List) (at HibernateSessionSourceImpl.java:36) via
org.apache.tapestry5.hibernate.modules.HibernateCoreModule.bind(ServiceBinder)

itself dependent on service 'HibernateSessionSource'.
at
org.apache.tapestry5.ioc.internal.services.JustInTimeObjectCreator.obtainObjectFromCreator(JustInTimeObjectCreator.java:75)
It looks like I can't inject the HibernateSessionSource because my
Configurer is called from there (maybe a circular dependency?):
public HibernateSessionSourceImpl(Logger logger,
List hibernateConfigurers) {
l// ...
for (HibernateConfigurer configurer : hibernateConfigurers)
configurer.configure(configuration);
// ...
}
I don't see another way of getting the HibernateSessionSource or the
SessionFactory.

If you use the 'new' keyword directly, no injection is done. The
shortest way is to use config.addInstance("EventListener",
EventListenerHibernateConfigurer.class). That will instantiate your
class and do injections as if it was a service.

[5.4] hibernate events
Hi, today I tried to add some hibernate event listeners to my
application. This was my first naive approach:
in AppModule
public static void
contributeHibernateSessionSource(OrderedConfiguration
config) {
config.add("EventListener", new
EventListenerHibernateConfigurer());
}
my EventListener
public class EventListenerHibernateConfigurer implements
HibernateConfigurer {
@Inject
SolrIndexer solrIndexer;
@Inject
private HibernateSessionSource hss;
@Override
public void configure(Configuration configuration) {
EventListenerRegistry registry = ((SessionFactoryImpl)
hss.getSessionFactory()).getServiceRegistry().getService(
EventListenerRegistry.class);
registry.getEventListenerGroup(EventType.PERSIST).appendListener(new
MyPersistEventListener(solrIndexer));
}
}
First of all I found no way of register an event only with the
configuration object
(http://stackoverflow.com/questions/8616146/eventlisteners-using-hibernate-4-0-with-spring-3-1-0-release).
Second the injection does not work. But how do I get my SolrIndexer into
the my event listener?
Thanks in advance
Matthias
