Caching with Infinispan


Spring Caching with Infinispan

JBoss Infinispan is popular distributed caching solution, it is the base of RedHad Data Grid product.
In the real world projects, Infinispan can work in several ways.
  • Run as a standalone server.
  • Run as JBoss service.
  • Embedded.
Infinispan also provides Spring integration, and provides two different CacheManager implementations for embedded way and standalone servers.
This post focus on the embedded way, the next post will contain the standalone environment configuration.

Enable Caching

Add @EnableCaching(mode=AdviceMode.ASPECTJ) annotation on the configuration class if you are using Java based configuration.
@Configuration
...
@EnableCaching(mode=AdviceMode.ASPECTJ)
public class JpaConfig {...}
Then, specify a CacheManager provider in your configuration. There is a SpringEmbeddedCacheManager provided by Infinispan Spring integration.
@Override
@Bean
public CacheManager cacheManager() {

 return new SpringEmbeddedCacheManager(
   new DefaultCacheManager(
    new ConfigurationBuilder()
     .eviction()
      .maxEntries(20000)
      .strategy(EvictionStrategy.LIRS)
     .expiration()
      .wakeUpInterval(5000L)
      .maxIdle(120000L)
       .build()
    )
   );
}

@Override
@Bean
public KeyGenerator keyGenerator() {
 return new SimpleKeyGenerator();
}
Do not forget to add the infinispan-spring dependency in your Maven pom.xml file.
<dependency>
 <groupId>org.infinispan</groupId>
 <artifactId>infinispan-spring</artifactId>
</dependency>
