2.4.8. Cache

In order to optimize your database accesses, you can activate the so called second level cache of Hibernate. This cache is configurable on a per entity and per collection basis.
@org.hibernate.annotations.Cache defines the caching strategy and region of a given second level cache. This annotation can be applied on the root entity (not the sub entities), and on the collections. 
@Entity
@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
public class Forest { ... }
    @OneToMany(cascade=CascadeType.ALL, fetch=FetchType.EAGER)
    @JoinColumn(name="CUST_ID")
    @Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
    public SortedSet<Ticket> getTickets() {
        return tickets;
    }
@Cache( CacheConcurrencyStrategy usage(); String region() default ""; String include() default
        "all"; )
