public class HibernateTransactionalAccessStrategy extends HibernateAccessStrategyAdapter
It is supposed that this strategy is used in JTA environment and Hibernate and
IgniteInternalCache corresponding to the L2 cache region are configured to use the same transaction manager.
Configuration of L2 cache and per-entity cache access strategy can be set in the Hibernate configuration file:
<hibernate-configuration>
<!-- Enable L2 cache. -->
<property name="cache.use_second_level_cache">true</property>
<!-- Use Ignite as L2 cache provider. -->
<property name="cache.region.factory_class">org.apache.ignite.cache.hibernate.HibernateRegionFactory</property>
<!-- Specify entity. -->
<mapping class="com.example.Entity"/>
<!-- Enable L2 cache with transactional access strategy for entity. -->
<class-cache class="com.example.Entity" usage="transactional"/>
</hibernate-configuration>
Also cache access strategy can be set using annotations:
@javax.persistence.Entity
@javax.persistence.Cacheable
@org.hibernate.annotations.Cache(usage = CacheConcurrencyStrategy.TRANSACTIONAL)
