Unable to resolve name [org.hibernate.cache.ehcache.EhCacheRegionFactory] as strategy [org.hibernate.cache.spi.RegionFactory]

Question

I was trying to upgrade my Spring and Hibernate version. I was using hibernate 3 and now I have upgraded to hibernate 4.3.6. After upgrading I am getting a weird issue in ehcache implementation.

As I have upgraded to hibernate 4, i have added one entry as:

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

And now I am getting the exception as:

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/config/persistence.xml]: Invocation of init method failed; nested exception is org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.cache.spi.RegionFactory]

I tried all the possible ways but this is not fixing this issue.

Are you configuring Hibernate using spring? If so make sure the versions are compatible ie., spring vs Hibernate versions — Zeus, Dec 17 '14 at 15:44

In Hibernate 4, if you want to use Ehcache, you must add a specific dependency: hibernate-ehcache

But it embeds Ehcache 2.4.3 So you should exclude the embeded Ehcache dependency.

<dependency>
 <groupId>org.hibernate</groupId>
 <artifactId>hibernate-ehcache</artifactId>
 <version>4.1.9.Final</version>
 <exclusions>
     <exclusion>
         <groupId>net.sf.ehcache</groupId>
         <artifactId>ehcache-core</artifactId>
     </exclusion>
 </exclusions>
</dependency>

For Hibernate-ehcache from version 5.1.0.Final which uses Ehcache 2.10.1 the same exclusion looks slightly different (ehcache instead of ehcache-core)

<dependency>
 <groupId>org.hibernate</groupId>
 <artifactId>hibernate-ehcache</artifactId>
 <version>5.1.0.Final</version>
 <exclusions>
     <exclusion>
         <groupId>net.sf.ehcache</groupId>
         <artifactId>ehcache</artifactId>
     </exclusion>
 </exclusions>
</dependency>

and then depending on the version of ehcache, you need to add ehcache or ehcache-core

Up to 2.6.x:

<dependency>
 <groupId>net.sf.ehcache</groupId>
 <artifactId>ehcache-core</artifactId>
 <version>2.5.7</version>
</dependency>

for 2.7 and above

<dependency>
 <groupId>net.sf.ehcache</groupId>
 <artifactId>ehcache</artifactId>
 <version>2.7.0</version> <!--  or above --> 
</dependency>

and for 3.0 and above

<dependency>
    <groupId>org.ehcache</groupId>
    <artifactId>ehcache</artifactId>
    <version>3.0.0</version>
</dependency>

Using Ehcache 3.0 and above with currently available Hibernate-ehcache version (5.2.10.Final) is probably not possible (there will be errors). You can use only Ehcache 2.x.x with it. But it is for now. In future it will probably change with new Hibernate-ehcache version. — luke, Jul 29 '17 at 14:59

use following dependency:

     <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-ehcache</artifactId>
        <version>4.3.7.Final</version>
    </dependency>
