hibernate 4.3.0 2 level cache configuration

Question

In Hibernate version 3.X it's possible to configure 2 level cache in hibernate.cfg like this:

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

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

In version 4.3.0 there is no class EhCacheProvider in org.hibernate.cache package.

What is the workaround for this situation?

Thanks

Answer 1

STEP 1 Add EHcache dependency

Hibernate ships with the ehcache library

1.1] Maven Dependency

add maven dependency for Ehcache in your application as

<dependency>
    <groupId>net.sf.ehcache</groupId>
    <artifactId>ehcache</artifactId>
    <version>[2.0.0]</version>
    <type>pom</type>
</dependency>

1.2] Download Jar file

If you are not using maven dependency you can download the jars file from Download URL add this jar file into lib directory and your project CLASSPATH .

STEP 2 Configuring EhCache

To configure ehcache, you need to do two steps:

2.1] configure Hibernate for second level caching

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

2.2] specify the second level cache provider

Hibernate 3.3 and above

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

Hibernate 3.2 and below

<property name="hibernate.cache.region.provider_class">net.sf.ehcache.hibernate.EhCacheProvider</property>

hope this will help you !

Add below depenedency in your pom.

 <artifactId>hibernate-ehcache</artifactId>
