Hibernate JPA @PersistenceProperty Eample

@PersistenceProperty

The @PersistenceProperty annotation is used by the @PersistenceContext annotation to declare JPA provider properties that are passed to the underlying container when the EntityManager instance is created.

PersistenceProperty describes a single container or persistence provider property. Used in PersistenceContext.
Vendor specific properties may be included in the set of properties, and are passed to the persistence provider by the container when the entity manager is created. Properties that are not recognized by a vendor will be ignored.

@PersistenceContext(
    unitName = "CRM",
    properties = {
        @PersistenceProperty(
            name="org.hibernate.flushMode",
            value= "MANUAL"
        )
    }
)
private EntityManager entityManager;
