== Getting Started

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

[source,java]

public interface PersonRepository extends CrudRepository<Person, Long> {

List findByLastname(String lastname);

List 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("Matthew");
person.setLastname("Adams");
repository.save(person);

List<Person> lastNameResults = repository.findByLastname("Adams");
List<Person> firstNameResults = repository.findByFirstnameLike("M*");

} }

@Configuration @EnableCassandraRepositories class ApplicationConfig extends AbstractCassandraConfiguration {

@Override public String getContactPoints() { return "localhost"; }

@Override protected String getKeyspaceName() { return "springdata"; } }


=== Maven configuration

Add the Maven dependency:

[source,xml]

org.springframework.data spring-data-cassandra ${version}.RELEASE ----

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

[source,xml]

org.springframework.data spring-data-cassandra ${version}.BUILD-SNAPSHOT spring-libs-snapshot Spring Snapshot Repository https://repo.spring.io/libs-snapshot ----

== Getting Help

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

== 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 https://jira.spring.io/browse/DATACASS[issue tracker] to see if someone has already reported the problem.
  • If the issue doesn’t already exist, https://jira.spring.io/browse/DATACASS[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 https://repo.spring.io[repo.spring.io]), but if you want to try out the latest and greatest, Spring Data can be easily built with the https://github.com/takari/maven-wrapper[maven wrapper]. You also need JDK 1.8.

[source,bash]

$ ./mvnw clean install

If you want to build with the regular mvn command, you will need https://maven.apache.org/run-maven/index.html[Maven v3.5.0 or above].

Also see link:CONTRIBUTING.adoc[CONTRIBUTING.adoc] if you wish to submit pull requests, and in particular please sign the https://cla.pivotal.io/sign/spring[Contributor’s Agreement] before your first non-trivial change.

== Initial Contributors

=== Building reference documentation

Building the documentation builds also the project without running tests.

[source,bash]

$ ./mvnw clean install -Pdistribute

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