Enabling caching in Hibernate can be achieved by following these steps:

  1. Configuring cache-related properties in the Hibernate configuration file (such as hibernate.cfg.xml) is an example of this.
<property name="hibernate.cache.use_second_level_cache">true</property>
<property name="hibernate.cache.use_query_cache">true</property>
  1. Set up caching strategies for entity classes by adding cache-related configurations in the annotations or XML mapping files of the entity class, for example:
@Entity
@Cacheable
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public class User {
    //...
}
  1. You can specify a cache provider, either choosing to use Hibernate’s default cache provider (such as Ehcache) or a custom cache implementation.
  2. When conducting a search, you can utilize query caching to improve performance, for example:
Query query = session.createQuery("from User where id = :id");
query.setParameter("id", 1);
query.setCacheable(true);
User user = (User) query.uniqueResult();

By following the steps above, you can enable and configure caching in Hibernate to improve system performance and response speed.
