public Interface AvailableSettings

When enabled, allows calls to jakarta.persistence.EntityManager#refresh(Object) and org.hibernate.Session#refresh(Object) on a detached entity instance.

Values are true, which allows refreshing a detached instance and false, which does not. When refreshing is disallowed, an IllegalArgumentException is thrown.

The default behavior is to allow refreshing a detached instance unless Hibernate is bootstrapped via JPA.

Specifies a org.hibernate.context.spi.CurrentSessionContext for scoping the current session, either:

• jta, thread, or managed, or
• the name of a class implementing org.hibernate.context.spi.CurrentSessionContext.

org.hibernate.SessionFactory#getCurrentSession(), org.hibernate.context.spi.CurrentSessionContext

Setting to identify a org.hibernate.CustomEntityDirtinessStrategy to use. May specify either a class name or an instance.

org.hibernate.boot.SessionFactoryBuilder#applyCustomEntityDirtinessStrategy(CustomEntityDirtinessStrategy)

Controls how entity loaders are created.

When true, the default, the loaders are only created on first access; this ensures that all access patterns which are not useful to the application are never instantiated, possibly saving a substantial amount of memory for applications having many entities. The only exception is the loader for org.hibernate.LockMode#NONE, which will always be eagerly initialized; this is necessary to detect mapping errors.

false indicates that all loaders should be created up front; this will consume more memory but ensures all necessary memory is allocated right away.

When enabled, specifies that the persistent context should be discarded when either org.hibernate.Session#close() or jakarta.persistence.EntityManager#close() is called.

Event listener configuration properties follow the pattern hibernate.event.listener.eventType packageName.ClassName1, packageName.ClassName2

Specifies a class which implements org.hibernate.jpa.spi.IdentifierGeneratorStrategyProvider, and has a constructor with no parameters.

Set a default value for the hint SpecHints#HINT_SPEC_LOCK_SCOPE, used when the hint is not explicitly specified.

See JPA 2 sections 8.2.1.9 and 3.4.4.3

SpecHints#HINT_SPEC_LOCK_SCOPE

Set a default value for the hint SpecHints#HINT_SPEC_LOCK_TIMEOUT, used when the hint is not explicitly specified.

See JPA 2 sections 8.2.1.9 and 3.4.4.3

SpecHints#HINT_SPEC_LOCK_TIMEOUT

Setting that specifies how Hibernate will respond when multiple representations of the same persistent entity ("entity copy") are detected while merging.

The possible values are:

• disallow (the default): throws IllegalStateException if an entity copy is detected
• allow: performs the merge operation on each entity copy that is detected
• log: (provided for testing only) performs the merge operation on each entity copy that is detected and logs information about the entity copies. This setting requires DEBUG logging be enabled for org.hibernate.event.internal.EntityCopyAllowedLoggedObserver.

Alternatively, the application may customize the behavior by providing an implementation of org.hibernate.event.spi.EntityCopyObserver and setting the property hibernate.event.merge.entity_copy_observer to the class name.

When this property is set to allow or log, Hibernate will merge each entity copy detected while cascading the merge operation. In the process of merging each entity copy, Hibernate will cascade the merge operation from each entity copy to its associations with jakarta.persistence.CascadeType#MERGE or jakarta.persistence.CascadeType#ALL. The entity state resulting from merging an entity copy will be overwritten when another entity copy is merged.

When enabled, specifies that the generated identifier of an entity is unset when the entity is deleted.
