I wrote a Hibernate interceptor :
public class MyInterceptor extends EmptyInterceptor {
private boolean isCanal=false;
public boolean onSave(Object entity, Serializable arg1, Object[] arg2, String[] arg3, Type[] arg4) throws CallbackException {
for(int i=0;i<100;i++){
System.out.println("Inside MyInterceptor(onSave) : "+entity.toString());
}
if(entity instanceof Canal){
isCanal=true;
}
return false;
}
public void afterTransactionCompletion(Transaction tx){
if(tx.wasCommitted()&&(isCanal)){
for(int i=0;i<100;i++){
System.out.println("Inside MyInterceptor(afterTransactionCompletion) : Canal was saved to DB.");
}
}
}
I can see the method onSave executing fine, but afterTransactionCompletion method never gets executed even though the transaction is successfully commited to the database.
I need a way to track every time a Canal object is successfully saved to the DB and react by printing some messages. is that feasible ? and how ?
Here is the method I use to save objects in the DB :
public static Object enregObjet(Object obj) throws UpdateException,
EnregException, ErreurException {
Transaction tx = null;
try {
Session s = InterfaceBD.currentSession();
tx = s.beginTransaction();
try {
// Positionner les champs dteUti et dteUtiModif
Method dteUtiSetter = null;
;
// Objet en insertion
dteUtiSetter = obj.getClass().getMethod("setDteUti",
new Class[] { java.util.Date.class });
dteUtiSetter.invoke(obj, new Object[] { new java.util.Date() });
} catch (NoSuchMethodException ex) {
;// Le champ dteUtiModif n'existe pas
}
// Enregistrer
IardNum.numeroterCode(obj);
IardNum.numeroterId(obj);
s.save(obj);
s.flush();
tx.commit();
try {
String id = "";
// Positionner les champs dteUti et dteUtiModif
Method idGetter = null;
// Objet en insertion
idGetter = obj.getClass().getMethod("getId");
id = (String) idGetter.invoke(obj);
Connection conn = InterfaceBD.getConn();
IardGenerator3.cleanSeq(id, conn);
conn.close();
} catch (NoSuchMethodException ex) {
;// Le champ dteUtiModif n'existe pas
}
catch(ClassCastException ex){
;//just ignore it because we are dealing with a PK class (e.g : CausesAnnexesSinistrePK).
}
s.clear();
return obj;
}
