Describes the new features and capabilities added to Hibernate ORM in 7.1.
If migrating from earlier versions, be sure to also check out the Migration Guide for discussion of impactful changes.
Resource Discovery in SE Environments
The Jakarta Persistence specification defines the ability for a provider to discover "managed resources" in EE environments, alleviating the application from manually listing all classes and XML files. However, it defines no such support in SE environments.
Starting with 7.1, Hibernate now supports this discovery in SE environments, by allowing applications to specify the root URL and zero-or-more "jar" URLs to search. These URLs correspond to
-
jakarta.persistence.spi.PersistenceUnitInfo#getPersistenceUnitRootUrl
-
jakarta.persistence.spi.PersistenceUnitInfo#getJarFileUrls
These URLs are searched for managed resources according to the process defined in the specification.
Locking
org.hibernate.Locking
has been introduced to support various aspects of pessimistic locking:
-
Locking.Scope
is an extension ofjakarta.persistence.PessimisticLockScope
including some Hibernate-specific options. -
Locking.FollowOn
allows controlling Hibernate’s follow-on locking behavior.
Additionally, we’ve added org.hibernate.Timeouts
to help deal with some standard jakarta.persistence.Timeout
values.
Interceptor and merge
Support for intercepting Session#merge
events has been added to Hibernate’s Interceptor
.
