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

Here is a quick teaser of an application using Spring Data Repositories in Java:

public interface PersonRepository extends CrudRepository<Person, Long> {

  List<Person> findByLastname(String lastname);

  List<Person> findByFirstnameLike(String firstname);
}

@Service
public class MyService {

  private final PersonRepository repository;

  public MyService(PersonRepository repository) {
    this.repository = repository;
  }

  public void doWork() {

    repository.deleteAll();

    Person person = new Person();
    person.setFirstname("John");
    person.setLastname("Blum");
    repository.save(person);

    List<Person> lastNameResults = repository.findByLastname("Blum");
    List<Person> firstNameResults = repository.findByFirstnameLike("J*");
 }
}

Configure a Pivotal GemFire cache and Region (REPLICATE, PARTITION and so on):

<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:gfe="http://www.springframework.org/schema/gemfire"
	xmlns:gfe-data="http://www.springframework.org/schema/data/gemfire"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance
  xsi:schemaLocation="
    http://www.springframework.org/schema/beans https://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/geode https://www.springframework.org/schema/gemfire/spring-gemfire.xsd
	http://www.springframework.org/schema/data/gemfire https://www.springframework.org/schema/data/geode/spring-data-gemfire.xsd">

  <gfe:cache/>

  <gfe:partitioned-region id="ExampleRegion" copies="2">

  <bean id="gemfireTemplate" class="org.springframework.data.gemfire.GemfireTemplate" p:region-ref="ExampleRegion"/>
	<gfe-data:repositories base-package="com.acme"/>
</beans>

Maven configuration

Add the Maven dependency:

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

<repository>
  <id>spring-libs-snapshot</id>

</repository>

Getting Help

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-gemfire. You can also chat with the community on Gitter.

• Report bugs with Spring Data for Pivotal GemFire at jira.spring.io/browse/SGF.

Reporting Issues

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.

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.
