javax.cache.integration.CacheLoader<K,V>, javax.cache.integration.CacheWriter<K,V>, CacheStore<K,V>, LifecycleAware

public class CacheJdbcPojoStore<K,V>
extends CacheAbstractJdbcStore<K,V>

Implementation of CacheStore backed by JDBC and POJO via reflection. This implementation stores objects in underlying database using java beans mapping description via reflection.

Use CacheJdbcPojoStoreFactory factory to pass CacheJdbcPojoStore to CacheConfiguration.
