getting some problem into my spring application.
I have very fairly simple spring beans, they are injected into various other spring beans. While debugging I found, they are being called twice, Constructor & @PostConstruct both called two times.
My application have no front end technology. Its simply for backend task related.

Spring Bean Class
@Repository
public class TransactionDAO extends BasicDAO<Transaction, ObjectId> {
private Datastore datastore;
@Autowired
public TransactionDAO(Mongo mongo, Morphia morphia) {
super(mongo, morphia, "itransact");
morphia.map(Transaction.class);
// TO USE MONGO WITHOUT SECURITY
this.datastore = morphia.createDatastore(mongo, "itransact");
logger.debug("***** CONNECTED TO MONGODB SUCCESSFULLY *****");
this.datastore.ensureIndexes();
// this.datastore.ensureCaps();
}
}
Constructor "TransactionDAO" is being called twice.
I tried to watch call stack trace by
Throwable t = new Throwable();
System.out.println(t.getStackTrace()[1].toString());
and each time it showed the following
sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)
