= Spring Data for Elasticsearch image:https://jenkins.spring.io/buildStatus/icon?job=spring-data-elasticsearch%2Fmain&subject=Build[link=https://jenkins.spring.io/view/SpringData/job/spring-data-elasticsearch/] https://gitter.im/spring-projects/spring-data[image:https://badges.gitter.im/spring-projects/spring-data.svg[Gitter]] image:https://img.shields.io/badge/Revved%20up%20by-Develocity-06A0CE?logo=Gradle&labelColor=02303A["Revved up by Develocity", link="https://ge.spring.io/scans?search.rootProjectNames=Spring Data Elasticsearch"]



The primary goal of the https://projects.spring.io/spring-data[Spring Data] project is to make it easier to build Spring-powered applications that use new data access technologies such as non-relational databases, map-reduce frameworks, and cloud based data services.



The Spring Data Elasticsearch project provides integration with the https://www.elastic.co/[Elasticsearch] search engine.

Key functional areas of Spring Data Elasticsearch are a POJO centric model for interacting with Elasticsearch Documents and easily writing a Repository style data access layer.



This project is lead and maintained by the community.



== Features



* Spring configuration support using Java based `@Configuration` classes or an XML namespace for an ES client instances.

* `ElasticsearchOperations` class and implementations that increases productivity performing common ES operations.

Includes integrated object mapping between documents and POJOs.

* Feature Rich Object Mapping integrated with Spring’s Conversion Service

* Annotation based mapping metadata

* Automatic implementation of `Repository` interfaces including support for custom search methods.

* CDI support for repositories



== Code of Conduct



This project is governed by the https://github.com/spring-projects/.github/blob/e3cc2ff230d8f1dca06535aa6b5a4a23815861d4/CODE_OF_CONDUCT.md[Spring Code of Conduct].

By participating, you are expected to uphold this code of conduct.

Please report unacceptable behavior to [email protected].



== Getting Started



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



[source,java]

----

public interface PersonRepository extends CrudRepository {



  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("Oliver");

    person.setLastname("Gierke");

    repository.save(person);



    List lastNameResults = repository.findByLastname("Gierke");

    List firstNameResults = repository.findByFirstnameLike("Oli");

 }

}

----



=== Using the RestClient



Please check the [official documentation](https://docs.spring.io/spring-data/elasticsearch/docs/current/reference/html/#elasticsearch.clients.configuration).



=== Maven configuration



Add the Maven dependency:



[source,xml]

----



  org.springframework.data

  spring-data-elasticsearch

  ${version}



----



**Compatibility Matrix**



The compatibility between Spring Data Elasticsearch, Elasticsearch client drivers and Spring Boot versions can be found in the https://docs.spring.io/spring-data/elasticsearch/docs/current/reference/html/#preface.versions[reference documentation].



To use the Release candidate versions of the upcoming major version, use our Maven milestone repository and declare the appropriate dependency version:



[source,xml]

----



  org.springframework.data

  spring-data-elasticsearch

  ${version}.RCx 



  spring-snapshot

  Spring Snapshot Repository

  https://repo.spring.io/milestone



----



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-elasticsearch

  ${version}-SNAPSHOT



  spring-snapshot

  Spring Snapshot Repository

  https://repo.spring.io/snapshot

== Getting Help



Having trouble with Spring Data?

We’d love to help!



* Check the

https://docs.spring.io/spring-data/elasticsearch/docs/current/reference/html/[reference documentation], and https://docs.spring.io/spring-data/elasticsearch/docs/current/api/[Javadocs].

* Learn the Spring basics – Spring Data builds on Spring Framework, check the https://spring.io[spring.io] web-site for a wealth of reference documentation.

If you are just starting out with Spring, try one of the https://spring.io/guides[guides].

* Ask a question or chat with the community on https://app.gitter.im/#/room/#spring-projects_spring-data:gitter.im[Gitter].

* Report bugs with Spring Data for Elasticsearch at https://github.com/spring-projects/spring-data-elasticsearch/issues[https://github.com/spring-projects/spring-data-elasticsearch/issues].



== 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

https://github.com/spring-projects/spring-data-elasticsearch/issues[issue tracker] to see if someone has already reported the problem.

* If the issue doesn't already exist, https://github.com/spring-projects/spring-data-elasticsearch/issues/new[create a new issue].

* Please provide as much information as possible with the issue report, we like to know the version of Spring Data Elasticsearch 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 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 need JDK 17 or above to build the _main_ branch.

For the branches up to and including release 4.4, JDK 8 is required.



[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 submitting your first pull request._



IMPORTANT: When contributing, please make sure an issue exists in https://github.com/spring-projects/spring-data-elasticsearch/issues[issue tracker] and comment on this issue with how you want to address it.

By this we not only know that someone is working on an issue, we can also align architectural questions and possible solutions before work is invested . We so can prevent that much work is put into Pull Requests that have little or no chances of being merged.



=== Building reference documentation



Building the documentation builds also the project without running tests.



[source,bash]

----

 $ ./mvnw clean install -Pantora

----



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