Hibernate：flush（）和commit（）

在Hibernate手册中，您可以看到此示例

Session session = sessionFactory.openSession();Transaction tx = session.beginTransaction();for (int i = 0; i < 100000; i++) {    Customer customer = new Customer(...);    session.save(customer);    if (i % 20 == 0) { // 20, same as the JDBC batch size        // flush a batch of inserts and release memory:        session.flush();        session.clear();    }}tx.commit();session.close();

如果不调用flush方法，则一级缓存将抛出OutOfMemoryException
