The primary goal of the 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 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.
-
Spring configuration support using Java based
@Configurationclasses or an XML namespace for an ES client instances. -
ElasticsearchOperationsclass 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
Repositoryinterfaces including support for custom search methods. -
CDI support for repositories
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 [email protected].
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("Oliver");
person.setLastname("Gierke");
repository.save(person);
List<Person> lastNameResults = repository.findByLastname("Gierke");
List<Person> firstNameResults = repository.findByFirstnameLike("Oli");
}

-
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 need JDK 17 or above to build the main branch. For the branches up to and including release 4.4, JDK 8 is required.
$ ./mvnw clean installIf you want to build with the regular mvn command, you will need Maven v3.5.0 or above.
