redisson/redisson-hibernate

Redis based Hibernate Cache implementation

Implements Hibernate 2nd level Cache provider based on Redisson.
Supports all Hibernate cache strategies: READ_ONLY, NONSTRICT_READ_WRITE, READ_WRITE and TRANSACTIONAL.

Compatible with Hibernate 4.x, 5.x

_{Please consider Redisson PRO version for advanced features and support by SLA.}

Usage

1. Add redisson-hibernate dependency into your project:

1. For JDK 1.8+

   Maven

   <dependency>
       <groupId>org.redisson</groupId>
       <!-- for Hibernate v4.x -->
       <artifactId>redisson-hibernate-4</artifactId>
       <!-- for Hibernate v5.0.x - v5.1.x -->
       <artifactId>redisson-hibernate-5</artifactId>
       <!-- for Hibernate v5.2.x -->
       <artifactId>redisson-hibernate-52</artifactId>
       <!-- for Hibernate v5.3.x -->
       <artifactId>redisson-hibernate-53</artifactId>
       <version>3.10.0</version>
   </dependency>
   

   Gradle

   // for Hibernate v4.x
   compile 'org.redisson:redisson-hibernate-4:3.10.0'
   // for Hibernate v5.0.x - v5.1.x
   compile 'org.redisson:redisson-hibernate-5:3.10.0'
   // for Hibernate v5.2.x
   compile 'org.redisson:redisson-hibernate-52:3.10.0'
   // for Hibernate v5.3.x
   compile 'org.redisson:redisson-hibernate-53:3.10.0'
   

2. For JDK 1.6+

   Maven

   <dependency>
       <groupId>org.redisson</groupId>
       <!-- for Hibernate v4.x -->
       <artifactId>redisson-hibernate-4</artifactId>
       <!-- for Hibernate v5.0.x - v5.1.x -->
       <artifactId>redisson-hibernate-5</artifactId>
       <version>2.15.0</version>
   </dependency>
   

   Gradle

   // for Hibernate v4.x
   compile 'org.redisson:redisson-hibernate-4:2.15.0'
   // for Hibernate v5.0.x - v5.1.x
   compile 'org.redisson:redisson-hibernate-5:2.15.0'
   

2. Specify hibernate cache settings

<!-- 2nd level cache activation -->
<property name="hibernate.cache.use_second_level_cache" value="true" />
<property name="hibernate.cache.use_query_cache" value="true" />

<!-- Redisson Hibernate Cache factory -->
<property name="hibernate.cache.region.factory_class" value="org.redisson.hibernate.RedissonRegionFactory" />
<!-- Redisson YAML config (searched in filesystem and classpath) -->
<property name="hibernate.cache.redisson.config" value="/redisson.yaml" />
<!-- Redisson JSON config (searched in filesystem and classpath) -->
<property name="hibernate.cache.redisson.config" value="/redisson.json" />

Redisson allows to define follow cache settings per entity, collection, naturalid, query and timestamp regions:

eviction.max_entries - max size of cache. Superfluous entries are evicted using LRU algorithm. 0 value means unbounded cache. Default value: 0

expiration.time_to_live - time to live per cache entry in milliseconds. 0 value means this setting doesn't affect expiration. Default value: 0

expiration.max_idle_time - max idle time per cache entry in milliseconds. 0 value means this setting doesn't affect expiration. Default value: 0

Configuration examples:

<!-- cache definition for entity region. Example region name: "my_object" -->
<property name="hibernate.cache.redisson.my_object.eviction.max_entries" value="10000" />
<property name="hibernate.cache.redisson.my_object.expiration.time_to_live" value="600000" />
<property name="hibernate.cache.redisson.my_object.expiration.max_idle_time" value="300000" />

<!-- cache definition for collection region. Example region name: "my_list" -->
<property name="hibernate.cache.redisson.my_list.eviction.max_entries" value="10000" />
<property name="hibernate.cache.redisson.my_list.expiration.time_to_live" value="600000" />
<property name="hibernate.cache.redisson.my_list.expiration.max_idle_time" value="300000" />

<!-- cache definition for naturalid region. Suffixed by ##NaturalId. Example region name: "my_object" -->
<property name="hibernate.cache.redisson.my_object##NaturalId.eviction.max_entries" value="10000" />
<property name="hibernate.cache.redisson.my_object##NaturalId.expiration.time_to_live" value="600000" />
<property name="hibernate.cache.redisson.my_object##NaturalId.expiration.max_idle_time" value="300000" />

<!-- cache definition for query region. Example region name: "my_query" -->
<property name="hibernate.cache.redisson.my_entity.eviction.max_entries" value="10000" />
<property name="hibernate.cache.redisson.my_entity.expiration.time_to_live" value="600000" />
<property name="hibernate.cache.redisson.my_entity.expiration.max_idle_time" value="300000" />

<!-- cache definition for timestamps region. -->
<property name="hibernate.cache.redisson.timestamps.eviction.max_entries" value="10000" />
<property name="hibernate.cache.redisson.timestamps.expiration.time_to_live" value="600000" />
<property name="hibernate.cache.redisson.timestamps.expiration.max_idle_time" value="300000" />
