Question

I have a problem with spring-data-elasticsearch installing. I tried many ways to fix this but they didnt work. I'm studying course from udemy its 2016-2017 year and i'm using new version of dependencies of spring-data-elasticsearch, spring-data-jpa. Please help)

ElasticSearchConfig.java

@Configuration
@EnableElasticsearchRepositories("info.***.resume")
@ComponentScan(basePackages = {"info.***.resume.search"})
public class ElasticSearchConfig {
    @Value("${elasticsearch.home}")//C:/Users/*username*/IdeaProjects/resume/elastic-search-data
    private String elasticSearchHome;

    @Bean
    public Client client() throws UnknownHostException {
        Settings settings = Settings.builder()
                .put("client.transport.sniff", true)
                .put("path.home", elasticSearchHome)
                .put("cluster.name", "elasticsearch").build();
//            return new PreBuiltTransportClient(settings)
//                    .addTransportAddress(new TransportAddress(InetAddress.getByName("localhost"), 9300));

        TransportClient client = new PreBuiltTransportClient(settings);
        client.addTransportAddress(new TransportAddress(InetAddress.getByName("127.0.0.1"), 9300));
        return client;
    }

    @Bean
    public ElasticsearchOperations elasticsearchTemplate() throws UnknownHostException {
        return new ElasticsearchTemplate(client());
    }
}

ProfileSearchRepository.java

public interface ProfileSearchRepository extends ElasticsearchRepository<Profile, Long> {

    Page<Profile> findByObjectiveLikeOrSummaryLike(String objective, String summary, Pageable pageable);
}

            for (Profile p : findProfileService.findAllForIndexing()) {
                profileSearchRepository.save(p);
                LOGGER.info("Successful indexing of profile:{}", p.getUid());
            }
            LOGGER.info("Finish index of profiles");
        } else {
            LOGGER.info("IndexAllDuringStartup is disabled");
        }

    }
}

You are trying to create a deprecated transport client to interact with Elasticsearch, while Elasticsearch officially released high-level java rest-client which is a preferred method for clients to connect with Elasticsearch.

Transport client is used by nodes in the cluster for communication which will be totally removed in 8.X as mentioned in the same doc:

Deprecated in 7.0.0. The TransportClient is deprecated in favour of the Java High Level REST Client and will be removed in Elasticsearch 8.0. The migration guide describes all the steps needed to migrate.

You should create a preferred and official high-level java client as shown below:

import org.springframework.beans.factory.annotation.Autowired;@Configuration
static class Config {

  @Bean
  RestHighLevelClient client() {

    ClientConfiguration clientConfiguration = ClientConfiguration.builder() 
      .connectedTo("localhost:9200", "localhost:9201")
      .build();

    return RestClients.create(clientConfiguration).rest();                  
  }
}

Once created you can simply autowired this client and use it for all the operations of Elasticsearch.
