  <prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</prop> 
 <prop key="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.EhCacheRegionFactory</prop>

Show your java code first where you are doing transaction to the database. — msk, Feb 01 '17 at 07:29
public T find(Class entityClass, Long id) throws Exception { return (T) entityManager.find(entityClass, id); } — Kasyap, Feb 01 '17 at 08:36

You are using Ehcache 3 (which is good) but are using a region factory that is Ehcache 2 compatible.

For Ehcache 3, which is JCache compliant, you should use org.hibernate.cache.jcache.JCacheRegionFactory.

You will find a full example here: https://github.com/ehcache/ehcache3-samples/tree/master/fullstack. Have a look at the README.md to find the interesting files.

Note: As Louis mentioned in the comment, you need Hibernate 5.2 to get JCache support.

Note that this requires Hibernate 5.2+ – Louis Jacomet Feb 02 '17 at 13:58

I think you need this artifact:

<dependency> 
   <groupId>net.sf.ehcache</groupId> 
   <artifactId>ehcache-core</artifactId> 
   <version>2.10.3</version> 
</dependency>

It contains the net.sf.ehcache packages / classes that your application is looking for.

Based on your hibernate property:

<prop key="net.sf.ehcache.configurationResourceName">/ehcache.xml</prop>

thanks @kowalski now i am not getting any issue.But how to test this. – Kasyap Feb 01 '17 at 09:52
Glad it worked out for you. What is it you want to test exactly? – Maciej Kowalski Feb 01 '17 at 09:54
i added configurations to save entities and hql queries into ehcache.Now i want to know whether these are really saved or not. – Kasyap Feb 01 '17 at 10:09
don't mix ehcache2 and ehcache3; choose only 1 and stick with it; the question explicitly mentioned ehcache3 – Anthony Dahanne Feb 02 '17 at 13:22
