Initial SessionFactory creation failed: org.hibernate.cache.NoCacheRegionFactoryAvailableException:

Initial SessionFactory creation failed:  org.hibernate.cache.NoCacheRegionFactoryAvailableException: Second-level cache is used in the application, but property hibernate.cache.region.factory_class is not given, please either disable second level cache or set correct region factory class name to property hibernate.cache.region.factory_class (and make sure the second level cache provider, hibernate-infinispan, for example, is available in the classpath).

Problem: You are not provided or specified hibernate.cache.region.factory property in configuration file.

Solution:  You have to set the *hibernate.cache.region.factory_class* property. For instance with ehcache would be adding the following line:

<property name="hibernate.cache.region.factory_class">

org.hibernate.cache.internal.EhCacheRegionFactory

</property>

4.0 configured as follows:

<property name="hibernate.cache.use_second_level_cache">true</property>

<property name="hibernate.cache.region.factory_class"> org.hibernate.cache.ehcache.EhCacheRegionFactory</property>

3.3 configured as follows:

<property name="hibernate.cache.use_second_level_cache"> true </ property>

<property name="cache.provider_class">org.hibernate.cache.EhCacheProvider

</ property>

Complete two cache configuration:

Configuration before copying a file to the src folder under ehcache.xml

hibernate.cfg.xml settings:

1. <property name="hibernate.cache.use_second_level_cache">true</ property>

<property name="hibernate.cache.region.factory_class"> org.hibernate.cache.ehcache.EhCacheRegionFactory </ property>

2. @ Cache annotation (extensions provided by the hibernate)    

@ Cache (usage = CacheConcurrencyStrategy.READ_WRITE)

Need to add in the pom.xml

<dependency>

         <groupId>org.hibernate</groupId>

         <artifactId>hibernate-ehcache</artifactId>

         <version>4.1.12.Final</version>

       </dependency>

Otherwise it will error:

Unable to load class [org.hibernate.cache.ehcache.EhCacheRegionFactory]
