JarCastinghibernate-redis 
Hibernate (4.2.x.Final, 4.3.x.Final) 2nd level cache using Redis server. with Jedis 2.4.1 or higher
Reduce cache size by Fast-Serialization and snappy-java. Thanks!
See serialization benchmark.
NOTE
Don't use Hibernate 4.3.2.Final, 4.2.9.Final!!! It has bug in CacheKey! Recommend use 4.3.4.Final or 4.2.10.Final
Hibernate 4.3.2.Final CacheKey eliminate entityOrRoleName property for reduce CacheKey size. if multiple entity cached in same region, can't figure out wanted entity.

Setup Hibernate entity to use cache
Add @org.hibernate.annotations.Cache annotation to your Entity class
@Entity
@Cache(region="common", usage = CacheConcurrencyStrategy.READ_WRITE) // or @Cacheable(true) for JPA
@Getter
@Setter
public class Item implements Serializable {
@Id
@GeneratedValue
private Long id;
private String name;
private String description;
private static final long serialVersionUID = -281066218676472922L;
}
How to monitor hibernate-cache is running
Run "redis-cli monitor" command in terminal. you can see putting cached items, retrieving cached items.
