I am using Google Guice as dependency injection and Transaction purpose along with JPA and Hibernate.

I have added <property name="hibernate.jdbc.batch_size" value="20" /> in my persistence.xml file.

Here is my save entity list DAO code :

@Transactional
public void save(final List<T> entities) {
    final EntityManager em = getEntityManager();
    for (final T entity : entities) {
        if (!em.contains(entity)) {
            em.persist(entity);
        }
    }
}

Why it is not inserting in Database in batch of size 20 ?

@Lajos Arpad I am inserting 100 entities . It is inserting sequentially because I can see 100 insertion statement in log. – Badman Sep 21 '18 at 10:15
Which version of Hibernate do you use in this project? Did you check this answer https://stackoverflow.com/a/48129503/2849346 ? – MWiesner Sep 22 '18 at 14:16
