Unable to resolve name [org.hibernate.cache.ehcache.EhCacheRegionFactory] as strategy [org.hibernate.cache.spi.RegionFactory]
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.
Answer
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 or above</version>
</dependency>
and for 3.0 and above
<dependency>
<groupId>org.ehcache</groupId>
<artifactId>ehcache</artifactId>
<version>3.0.0</version>
</dependency>
