Spring Data Envers

This project is an extension of the Spring Data JPA project to allow access to entity revisions managed by Hibernate Envers. The sources mostly originate from a contribution of Philipp Hügelmeyer @hygl.

The core feature of the module consists of an implementation of the RevisionRepository of Spring Data Commons.

public interface RevisionRepository<T, ID extends Serializable, N extends Number & Comparable<N>> {

	Revision<N, T> findLastChangeRevision(ID id);

	Revisions<N, T> findRevisions(ID id);

	Page<Revision<N, T>> findRevisions(ID id, Pageable pageable);
}

You can pull in this functionality to your repositories by simply additionally extending the interface just mentioned:

interface PersonRepository extends RevisionRepository<Person, Long, Integer>, CrudRepository<Person, Long> {

  // Your query methods go here
}

To successfully activate the Spring Data Envers repository factory use the Spring Data JPA repositories namespace element's factory-class attribute:

<jpa:repositories base-package="com.acme.repositories"
                  factory-class="….EnversRevisionRepositoryFactoryBean" />
