elasticsearch srping boot connection 설정

application.properties 에

elasticsearch.host=192.168.0.50
elasticsearch.cluster_name=master <-- node name
elasticsearch.port=9200 <-- port 기본 9200
elasticsearch.user_name=elastic  <-- username
elasticsearch.user_password=설정한 비밀번호

 

추가 한다.

 

AbstractElasticsearchConfiguration 확장해서 연결 설정 할 수 있음.

 - RestHighLevelClient <-- 사용하는 것을 6.4 이상부터 권장 하고 있음

 

@Configuration
@EnableElasticsearchRepositories(basePackages = {"com.fourfree.elasticsearch"})
public class ElasticSearchConfig extends AbstractElasticsearchConfiguration {
    @Value("${elasticsearch.host}")
    private String host;

    @Value("${elasticsearch.port}")
    private String port;
    
    @Value("${elasticsearch.cluster_name}")
    private String clusterName;

    @Value("${elasticsearch.user_name}")
    private String userName;

    @Value("${elasticsearch.user_password}")
    private String userPassword;


    @Override
    @Bean
    public RestHighLevelClient elasticsearchClient() {
        final ClientConfiguration clientConfiguration = ClientConfiguration.builder()
                .connectedTo(host+":" + port)
                .withBasicAuth(userName,userPassword)
                .build();
        return RestClients.create(clientConfiguration).rest();
    }
    
    @Bean
    public ElasticsearchOperations elasticsearchOperations(){
        return new ElasticsearchRestTemplate(elasticsearchClient());
    }
