Class GridHibernateEntityRegion

java.lang.Object

org.gridgain.grid.cache.hibernate.GridHibernateRegion

org.gridgain.grid.cache.hibernate.GridHibernateTransactionalDataRegion

org.gridgain.grid.cache.hibernate.GridHibernateEntityRegion

All Implemented Interfaces:

org.hibernate.cache.spi.EntityRegion, org.hibernate.cache.spi.Region, org.hibernate.cache.spi.TransactionalDataRegion

public class GridHibernateEntityRegion
extends GridHibernateTransactionalDataRegion
implements org.hibernate.cache.spi.EntityRegion

Implementation of EntityRegion. This region is used to store entity data.

L2 cache for entity can be enabled in the Hibernate configuration file:

 <hibernate-configuration>
     <!-- Enable L2 cache. -->
     <property name="cache.use_second_level_cache">true</property>

     <!-- Use GridGain as L2 cache provider. -->
     <property name="cache.region.factory_class">org.gridgain.grid.cache.hibernate.GridHibernateRegionFactory</property>

     <!-- Specify entity. -->
     <mapping class="com.example.Entity"/>

     <!-- Enable L2 cache with nonstrict-read-write access strategy for entity. -->
     <class-cache class="com.example.Entity" usage="nonstrict-read-write"/>
 </hibernate-configuration>
 

Also cache for entity can be enabled using annotations:

 @javax.persistence.Entity
 @javax.persistence.Cacheable
 @org.hibernate.annotations.Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
 public class Entity { ... }
