Spring Data Elasticsearch

Spring Data implementation for ElasticSearch

Spring Data makes 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 as well as provide improved support for relational database technologies.

The Spring Data Elasticsearch project provides integration with the elasticsearch search engine.

Guide

Quick Start

Wiki page for Getting Started

Maven configuration

Add the Maven dependency:

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-elasticsearch</artifactId>
    <version>x.y.z.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-elasticsearch</artifactId>
  <version>x.y.z.BUILD-SNAPSHOT</version>
</dependency>

2.0.x 2.2.0

ElasticsearchRepository

A default implementation of ElasticsearchRepository, aligning to the generic Repository Interfaces, is provided. Spring can do the Repository implementation for you depending on method names in the interface definition.

The ElasticsearchCrudRepository extends PagingAndSortingRepository

    public interface ElasticsearchCrudRepository<T, ID extends Serializable> extends ElasticsearchRepository<T, ID>, PagingAndSortingRepository<T, ID> {
    }

Extending ElasticsearchRepository for custom methods

    public interface BookRepository extends Repository<Book, String> {

        List<Book> findByNameAndPrice(String name, Integer price);

        List<Book> findByNameOrPrice(String name, Integer price);
        
        Page<Book> findByName(String name,Pageable page);

        Page<Book> findByNameNot(String name,Pageable page);

        Page<Book> findByPriceBetween(int price,Pageable page);

        Page<Book> findByNameLike(String name,Pageable page);

        @Query("{\"bool\" : {\"must\" : {\"term\" : {\"message\" : \"?0\"}}}}")
        Page<Book> findByMessage(String message, Pageable pageable);
    }

Indexing a single document with Repository

        @Autowired
        private SampleElasticsearchRepository repository;

        String documentId = "123456";
        SampleEntity sampleEntity = new SampleEntity();
        sampleEntity.setId(documentId);
        sampleEntity.setMessage("some message");

        repository.save(sampleEntity);

Indexing multiple Document(bulk index) using Repository

        @Autowired
        private SampleElasticsearchRepository repository;

        String documentId = "123456";
        SampleEntity sampleEntity1 = new SampleEntity();
        sampleEntity1.setId(documentId);
        sampleEntity1.setMessage("some message");

        String documentId2 = "123457"
        SampleEntity sampleEntity2 = new SampleEntity();
        sampleEntity2.setId(documentId2);
        sampleEntity2.setMessage("test message");

        List<SampleEntity> sampleEntities = Arrays.asList(sampleEntity1, sampleEntity2);

        //bulk index
        repository.save(sampleEntities);

ElasticsearchTemplate

ElasticsearchTemplate is the central support class for elasticsearch operations.

Indexing a single document using Elasticsearch Template

        String documentId = "123456";
        SampleEntity sampleEntity = new SampleEntity();
        sampleEntity.setId(documentId);
        sampleEntity.setMessage("some message");
        IndexQuery indexQuery = new IndexQueryBuilder().withId(sampleEntity.getId()).withObject(sampleEntity).build();
        elasticsearchTemplate.index(indexQuery);

Indexing multiple Document(bulk index) using Elasticsearch Template

        @Autowired
        private ElasticsearchTemplate elasticsearchTemplate;

        List<IndexQuery> indexQueries = new ArrayList<IndexQuery>();
        //first document
        String documentId = "123456";
        SampleEntity sampleEntity1 = new SampleEntity();
        sampleEntity1.setId(documentId);
        sampleEntity1.setMessage("some message");

        IndexQuery indexQuery1 = new IndexQueryBuilder().withId(sampleEntity1.getId()).withObject(sampleEntity1).build();
        indexQueries.add(indexQuery1);

        //second document
        String documentId2 = "123457";
        SampleEntity sampleEntity2 = new SampleEntity();
        sampleEntity2.setId(documentId2);
        sampleEntity2.setMessage("some message");

        IndexQuery indexQuery2 = new IndexQueryBuilder().withId(sampleEntity2.getId()).withObject(sampleEntity2).build()
        indexQueries.add(indexQuery2);

        //bulk index
        elasticsearchTemplate.bulkIndex(indexQueries);

Searching entities using Elasticsearch Template

        @Autowired
        private ElasticsearchTemplate elasticsearchTemplate;

        SearchQuery searchQuery = new NativeSearchQueryBuilder()
        .withQuery(queryString(documentId).field("id"))
        .build();
        Page<SampleEntity> sampleEntities = elasticsearchTemplate.queryForPage(searchQuery,SampleEntity.class);

Reactive Elasticsearch

The ReactiveElasticsearchClient is a non official driver based on WebClient. It uses the request/response objects provided by the Elasticsearch core project.

@Configuration
public class Config {

  @Bean
  ReactiveElasticsearchClient client() {

    ClientConfiguration clientConfiguration = ClientConfiguration.builder()
      .connectedTo("localhost:9200", "localhost:9291")
      .build();

    return ReactiveRestClients.create(clientConfiguration);
  }
}

// ...

Mono<IndexResponse> response = client.index(request ->

  request.index("spring-data")
    .type("elasticsearch")
    .id(randomID())
    .source(singletonMap("feature", "reactive-client"))
    .setRefreshPolicy(IMMEDIATE)
);

The reactive client response, especially for search operations, is bound to the from (offset) & size (limit) options of the request.

ReactiveElasticsearchOperations is the gateway to executing high level commands against an Elasticsearch cluster using the ReactiveElasticsearchClient. The easiest way of setting up the ReactiveElasticsearchTemplate is via AbstractReactiveElasticsearchConfiguration.

@Configuration
public class Config extends AbstractReactiveElasticsearchConfiguration {

    @Bean
    @Override
    public ReactiveElasticsearchClient reactiveElasticsearchClient() {
        // ...
    }
}

If needed the ReactiveElasticsearchTemplate can be configured with default RefreshPolicy and IndicesOptions that get applied to the related requests by overriding the defaults of refreshPolicy() and indicesOptions().

template.save(new Person("Bruce Banner", 42))
    .doOnNext(System.out::println)
    .flatMap(person -> template.findById(person.id, Person.class))
    .doOnNext(System.out::println)
    .flatMap(person -> template.delete(person))
    .doOnNext(System.out::println)
    .flatMap(id -> template.count(Person.class))
    .doOnNext(System.out::println)
    .subscribe();

The above outputs the following sequence on the console.

> Person(id=QjWCWWcBXiLAnp77ksfR, name=Bruce Banner, age=42)
> Person(id=QjWCWWcBXiLAnp77ksfR, name=Bruce Banner, age=42)
> QjWCWWcBXiLAnp77ksfR
> 0

XML Namespace

You can set up repository scanning via xml configuration, which will happily create your repositories.
