sharing same hazelcast client instance for both Hibernate L2 cache and Spring Cache Abstraction using javaconfig

[jeff...@gmail.com]

Hi,

     My app is using both hibernate 2nd level cache and Spring cache abstraction.  Is there a way to configure them to share the same instance of the hazelcast client?  any help would be greatly appreciated

jpa properties for L2

public Properties jpaProperties() {

   Properties properties = new Properties();

 

      properties.put("hibernate.cache.region_prefix", dsContext.substring(1)+"#L2Cache");

      properties.put("javax.persistence.sharedCache.mode","ENABLE_SELECTIVE");

      //properties.put("hibernate.generate_statistics", "true");

      properties.put("hibernate.cache.use_second_level_cache", "true");

      properties.put("hibernate.cache.use_minimal_puts", "true");

      properties.put("hibernate.cache.region.factory_class", "com.hazelcast.hibernate.HazelcastCacheRegionFactory");

      properties.put("hibernate.cache.hazelcast.use_native_client", "true");

      properties.put("hibernate.cache.hazelcast.native_client_address", "162.70.20.204:9900");

  

   return properties;

}

Spring CacheManager bean

    @Bean

    public CacheManager cacheManager() {

        ClientConfig config = new ClientConfig();

        config.getNetworkConfig()

        .addAddress("162.70.20.182:9900")

        .addAddress("162.70.20.204:9900")

        .addAddress("162.70.10.128:9900");

        HazelcastInstance client = HazelcastClient.newHazelcastClient(config);

        return new HazelcastCacheManager(client);

    }

You can do that by using xml based configuration.

please try to combine configurations below.

Spring Cache Manager and Hibernate L2

Thank You Mesut.

Is there anyway this can be done in javaConfig?  xml based configuration is something we are trying to avoid we do not wish to configuration files on multiple server.

It is both possible and not possible.

If you use Hibernate L2 in embedded mode, there is a property hibernate.cache.hazelcast.instance_name that you can set. In Spring, you can get the same instance with Hazelcast.getHazelcastInstanceByName

If you use Hibernate L2 in client/server mode, there is no way to configure Hazelcast Client with a name.
please feel free to raise an enhancement ticket if you need it.
