The repository method invocation mechanism now post-processes the result of the actual method invocation in case it's not type-compatible with the return type of the invoked method and invokes a conversion if applicable. This allows us to register custom converters for well-known wrapper types. We currently support Optional from both Google Guava and JDK 8. Implementation notice We use some JDK 8 type stubs from the Spring Data Build project to be able to compile using JDKs < 8. This is necessary as we need to remain compatible with Spring 3.2.x for the Dijkstra release train and our test executions still run into some issues with it a Java 8 runtime (mostly ASM related). These issues were reported in [0, 1] and we'll probably get off the hack for Dijkstra GA by upgrading to Spring 3.2.9.

Spring Data Commons
Spring Data Commons is part of the umbrella Spring Data project that provides shared infrastructure across the Spring Data projects. Most importantly at the moment it contains technology neutral repository interfaces as well as a metadata model for persisting Java classes.
Features
- 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
Getting Help
This README as well as the reference documentation are the best places to start learning about Spring Data Commons.
The main project website contains links to basic project information such as source code, JavaDocs, Issue tracking, etc.
For more detailed questions, use the forum. If you are new to Spring as well as to Spring Data, look for information about Spring projects.
Contributing to Spring Data Commons##
Here are some ways for you to get involved in the community:
- Get involved with the Spring community on the Spring Community Forums. Please help out on the forum by responding to questions and joining the debate.
- Create JIRA tickets for bugs and new features and comment and vote on the ones that you are interested in.
- Github is for social coding: if you want to write code, we encourage contributions through pull requests from forks of this repository. If you want to contribute code this way, please reference a JIRA ticket as well covering the specific issue you are addressing.
- Watch for upcoming articles on Spring by subscribing to springframework.org
Before we accept a non-trivial patch or pull request we will need you to sign the contributor's agreement. Signing the contributor's agreement does not grant anyone commit rights to the main repository, but it does mean that we can accept your contributions, and you will get an author credit if we do. Active contributors might be asked to join the core team, and given the ability to merge pull requests.
