The Hibernate ORM 7.0 Beta1 release has just been published. Here are some highlights...
|
|
|
|
|
|
[[jpa-32]]
|
|
== Jakarta Persistence 3.2
|
|
|
|
7.0 migrates to Jakarta Persistence 3.2 which can be fairly disruptive. See the link:{migration-guide-url}#jpa-32[Migration Guide] for details.
|
|
|
|
See https://in.relation.to/2024/04/01/jakarta-persistence-3/[this blog post] for a summary of the changes in 3.2

|
|
|
|
[[java-17]]
|
|
== Java 17
|
|
|
|
Version 3.2 of Jakarta Persistence requires Java 17. Hibernate 7.0 therefore baselines on Java 17 whereas previous versions baseline on Java 11.
|
|
|
|
[[model-validations]]
|
|
== Domain Model Validations
|
|
|
|
7.0 does much more validation of an application's domain model and especially its mapping details, e.g.
|
|
|
|
* illegal combinations such as `@Basic` and `@ManyToOne` on the same attribute
|
|
* misplaced annotations such as an annotated getter method with FIELD access
|
|
* stricter following of JavaBean conventions
|
|
|
|
See the link:{migration-guide-url}#annotation-validation[Migration Guide] for details.
|
|
|
|
[[mapping-xml]]
|
|
== mapping.xsd
|
|
|
|
Hibernate 7.0 provides a new XSD that represents an "extension" of the Jakarta Persistence orm.xsd weaving in Hibernate-specific mapping features. The namespace for this extended mapping is `http://www.hibernate.org/xsd/orm/mapping`
|
|
|
|
For applications using Hibernate's legacy `hbm.xml` format, we provide a tool to help with the transformation.
|
|
See the link:{migration-guide-url}#hbm-transform[Migration Guide] for details.
|
|
|
|
|
|
[[hibernate-models]]
|
|
== Hibernate Models
|
|
|
|
7.0 migrates from https://github.com/hibernate/hibernate-commons-annotations/[Hibernate Commons Annotations] (HCANN) to the new https://github.com/hibernate/hibernate-models[Hibernate Models] project for low-level processing of an application domain model, reading annotations and weaving in XML mapping documents.
|
|
|
|
See the link:{migration-guide-url}#hibernate-models[Migration Guide] for details.
|
|
|
|
|
|
[[cleanup]]
|
|
== Clean-up
|
|
|
|
A lot of deprecated contracts and behavior has been removed. See the link:{migration-guide-url}#cleanup[Migration Guide] for details. |
