class ApplicationConfiguration extends AbstractElasticsearchConfiguration {
@Bean
@Override
public RestHighLevelClient elasticsearchClient() {
return RestClients.create(ClientConfiguration.localhost()).rest();

@Autowired ElasticsearchOperations operations;
// ...
CriteriaQuery query = new CriteriaQuery("keywords").contains("java");
List<Conference> result = operations.find(query, Conference.class);
interface ConferenceRepository extends ElasticsearchRepository<Conference, String> {
List<Conference> findAllByKeywordsContains(String keyword);
}
// ...
@Autowired ConferenceRepository repository;
// ...
List<Conference> result = repository.findAllByKeywordsContains("java");
