A JPA 2 XML descriptor syntax for overriding is defined as well).Annotations can be split in two categories, the logical mapping annotations (describing the object model, the association between two entities etc.) and the physical mapping annotations (describing the physical schema, tables, columns, indexes, etc).If you use Hibernate Core and its native APIs read on.

HBM files are then prioritized over annotated metadata on a class to class basis.

You can change the priority using as the new generators are more efficient and closer to the JPA 2 specification semantic.

At all time you can fall back to Hibernate native APIs, or if required, even to native JDBC and SQL.

This release of is based on the final release of the JPA 2 specification (aka JSR-317) and supports all its features (including the optional ones).

You can get the test suite sources in the distribution.

column, and the entity manager will use it to detect conflicting updates (preventing lost updates you might otherwise see with the last-commit-wins strategy).We will mix annotations from both categories in the following code examples. You favorite IDE can auto-complete annotations and their attributes for you (even without a specific "JPA" module, since JPA annotations are plain JDK 5 annotations).A good an complete set of working examples can be found in the Hibernate Annotations test suite itself: most of the unit tests have been designed to represent a concrete example and be a source of inspiration for you.However they are not backward compatible with existing databases (if a sequence or a table is used for id generation).Hibernate Annotations utilizes Simple Logging Facade for Java (SLF4J) in order to log various system events.offers a complete (and standalone) JPA persistence solution on top of the mature Hibernate Core.You may use a combination of all three together, annotations without JPA programming interfaces and lifecycle, or even pure native Hibernate Core, depending on the business and technical needs of your project.The resource element can be either an hbm file or an EJB3 XML deployment descriptor.The distinction is transparent for your configuration process.Alternatively, you can define the annotated classes and packages using the programmatic APIAnnotation Configuration() Package("test.animals") //the fully qualified package name Annotated Class(Flight.class) Annotated Class(Sky.class) Annotated Class(Person.class) Annotated Class(Dog.class) Resource("test/animals/orm.xml")There is no other difference in the way you use Hibernate APIs with annotations, except for this startup routine change or in the configuration file.You can use your favorite configuration method for other properties ( To ease the migration process from hbm files to annotations, the configuration mechanism detects the mapping duplication between annotations and hbm files.
