Spring Data Envers icon?job=spring data envers%2Fmaster&subject=Build Gitter

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.

Code of Conduct

This project is governed by the Spring Code of Conduct. By participating, you are expected to uphold this code of conduct. Please report unacceptable behavior to spring-code-of-conduct@pivotal.io.

Getting Started

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" />

Maven configuration

Add the Maven dependency:

<dependency>
  <groupId>org.springframework.data</groupId>
  <artifactId>spring-data-envers</artifactId>
  <version>${version}.RELEASE</version>
</dependency>

If you’d rather like the latest snapshots of the upcoming major version, use our Maven snapshot repository and declare the appropriate dependency version.

<dependency>
  <groupId>org.springframework.data</groupId>
  <artifactId>spring-data-envers</artifactId>
  <version>${version}.BUILD-SNAPSHOT</version>
</dependency>

Getting Help

Having trouble with Spring Data? We’d love to help!

Reporting Issues

Spring Data uses GitHub as issue tracking system to record bugs and feature requests. If you want to raise an issue, please follow the recommendations below:

  • Before you log a bug, please search the issue tracker to see if someone has already reported the problem.

  • If the issue doesn’t already exist, create a new issue.

  • Please provide as much information as possible with the issue report, we like to know the version of Spring Data that you are using and JVM version.

  • If you need to paste code, or include a stack trace use Markdown ``` escapes before and after your text.

  • If possible try to create a test-case or project that replicates the issue. Attach a link to your code or a compressed file containing your code.

Building from Source

You don’t need to build from source to use Spring Data (binaries in repo.spring.io), but if you want to try out the latest and greatest, Spring Data can be easily built with the maven wrapper. You also need JDK 1.8.

 $ ./mvnw clean install

If you want to build with the regular mvn command, you will need Maven v3.5.0 or above.

Also see CONTRIBUTING.adoc if you wish to submit pull requests, and in particular please sign the Contributor’s Agreement before your first non-trivial change.

Building reference documentation

Building the documentation builds also the project without running tests.

 $ ./mvnw clean install -Pdistribute

The generated documentation is available from target/site/reference/html/index.html.
