Batch Insertions with Hibernate & Spring

Question

My application is based on Hibernate 3.2 and Spring 2.5. Here is the transaction management related snippet from the application context:

Answer 1

For the batch insertion with hibernate, the best practice is StatelessSession, it doesn`t cache any states of your entity, you will not encounter OutOfMemory, the code like:

if (books == null || books.isEmpty) {
    return;
}
StatelessSession session = getHibernateTemplate().getSessionFactory().openStatelessSession();
Transaction tx = session.beginTransaction();

for (Book each : books) {           
    session.insert(book);           
}
tx.commit();
session.close();

And the Transaction of StatelessSession is independent from the current transaction context.
