Have you configured the second-level cache mechanism in Hibernate?

Yes, I configured second-level cache in Hibernate to improve application performance by reducing the number of database accesses. Typically, a cache provider such as Ehcache or Infinispan is chosen, and the Hibernate configuration specifies the use of second-level cache.

Example configuration in hibernate.cfg.xml:

<property name="hibernate.cache.use_second_level_cache">true</property>
<property name="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.EhCacheRegionFactory</property>

For entities, the @Cache annotation with the appropriate strategy is used:

@Entity
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public class Product {
    // fields and methods
}

This allows Hibernate to cache entity data between sessions, reducing database load.
