Hibernate Javadoc (6.4.4.Final)

Hibernate ORM Javadocs

Hibernate is a library for object/relation mapping (ORM). It provides:

  • a native API centered around SessionFactory and Session,
  • an implementation of the Java (or Jakarta) Persistence API (JPA), where the equivalent central interfaces are EntityManagerFactory and EntityManager,
  • a set of mapping annotations which augment the O/R mapping annotations defined by JPA, and which may be used with either API, and
  • compile-time tooling for writing more type-safe code.

Native API

Along with SessionFactory and Session, applications using the native API will often make use of the following interfaces:

JPA

The JPA interfaces are defined by the JPA specification. For details see the latest specification along with the API documentation for the package jakarta.persistence.

Along with EntityManagerFactory and EntityManager, programs based on the standard JPA API often use:

  • Persistence to bootstrap Hibernate via JPA,
  • TypedQuery to execute queries,
  • EntityGraph to control the boundaries of fetched data,
  • EntityTransaction to control local transactions,
  • jakarta.persistence.Metamodel to implement generic code which makes use of persistent entity classes in a reflective fashion, and
  • CriteriaBuilder to build JPA criteria queries.

Note that since Hibernate 5.2, the native API extends the JPA API rather than wrapping it. For example, SessionFactory extends EntityManagerFactory, and Session extends EntityManager.

It's always possible to fall back from JPA interfaces to native APIs, by calling entityManager.unwrap(Session.class), entityManagerFactory.unwrap(SessionFactory.class), or query.unwrap(Query.class). In certain cases it's also possible to access native functionality by passing a JPA-defined or Hibernate-defined hint, at the cost of a loss of type-safety.

These packages define additional extensions to the JPA APIs:

Mapping annotations

The mapping annotations defined by the JPA specification provide a foundation for expressing object/relational mappings in Hibernate and other JPA implementations.

The annotations in the package org.hibernate.annotations extend this foundation and accommodate more specialized requirements. These annotation are not tied to the native API, and may be used in conjunction with the JPA API.

The full power of Hibernate can only be unlocked via judicious use of these extra annotations.

XML-based mappings

Annotation-based mappings are the best choice for most users, but Hibernate offers XML-based mappings as an alternative.
  • The JPA-standard XML schema is orm_3_0.xsd.
  • Hibernate extends this schema with some additional mapping elements. The extended schema is mapping-3.1.0.xsd.
  • Prior to the existence of JPA, Hibernate had its own format for XML-based mappings, which still works, though it has not been improved in a long time. The DTD is hibernate-mapping-3.0.dtd

Bootstrapping Hibernate

There are four basic ways to obtain an instance of Hibernate:

All major Java application servers and microservice frameworks come with built-in support for Hibernate. Such container environments also typically feature facilities to automatically manage the lifecycle of a EntityManager or Session and its association with container-managed transactions.

Example configuration files for JPA and native usage may be found here. A comprehensive list of configuration properties understood by Hibernate may be found in the class AvailableSettings. Most sensible programs will only ever need to use a tiny handful of them.

Annotations driving compile-time tooling

The annotations defined by org.hibernate.annotations.processing instruct the Metamodel Generator to validate HQL at compile time, and to automatically generate the implementation of finder methods and query methods.

Popular extension points

Hibernate offers an enormous wealth of extension points for customizing almost any aspect of its implementation. Most of these extension points are far too technical to be of interest to the typical application developer.

However, the following extension points are of quite general interest:

More advanced extension points include:

Finally, Hibernate ORM Core is itself a framework for advanced extensions like Hibernate Search, Hibernate Reactive, and Envers, which do much more than just implementing a single well-defined extension point. The starting points for such extensions are found in the packages org.hibernate.integrator.spi and org.hibernate.event.spi.

Package categories

The organization of code into packages is based on the following classification:

  • API packages include classes and interfaces which are used directly by a typical application. These packages never have spi nor internal in their name, and are not under the namespace org.hibernate.testing.
  • SPI packages include classes and interfaces which are used by integrators, library developers, and framework developers to develop extensions to Hibernate, or to alter its behavior in some way. These packages usually have spi in their name.
  • Some classes and interfaces are considered part of the internal implementation of Hibernate. This category includes packages with internal in their name, along with any class or interface annotated @Internal. Clients should avoid depending directly on these types.
  • The hibernate-testing module, and the namespace org.hibernate.testing contain testing support used in the Hibernate test suite.
