Spring Data Commons

Spring Data Commons is part of the umbrella Spring Data project that provides shared infrastructure across the Spring Data projects. It contains technology neutral repository interfaces as well as a metadata model for persisting Java classes.

Our primary goals are:

• Powerful Repository and custom object-mapping abstractions

• Support for cross-store persistence

• Dynamic query generation from query method names

• Implementation domain base classes providing basic properties

• Support for transparent auditing (created, last changed)

• Possibility to integrate custom repository code

• Easy Spring integration with custom namespace

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.

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

• Check the reference documentation, and Javadocs.

• Learn the Spring basics – Spring Data builds on Spring Framework, check the spring.io web-site for a wealth of reference documentation. If you are just starting out with Spring, try one of the guides.

• If you are upgrading, check out the changelog for “new and noteworthy” features.

• Ask a question - we monitor stackoverflow.com for questions tagged with spring-data. You can also chat with the community on Gitter.

• Report bugs with Spring Data Commons at jira.spring.io/browse/DATACMNS.

Spring Data uses JIRA 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 JIRA {code}…{code} 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.

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.

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.
