Spring data elasticsearch 6.8.5 how config HTTP port - spring-boot

Question

I use Elasticsearch version 6.8.5 with 9201 is HTTP port and 9301 is port of cluster node.
On my project, I use spring boot (spring-boot-starter-data-elasticsearch). On application.properties file, I set port of cluster node:
spring.data.elasticsearch.cluster-nodes=localhost:9301
But I don't know how to set HTTP port. So when I start my project, I get an error:
NoNodeAvailableException[None of the configured nodes are available: [{#transport#-1}{de81Kcj-QUqTRdA9HskFWg}{localhost}{localhost:9301}]];
I tried to use High Level REST Client setting (https://docs.spring.io/spring-data/elasticsearch/docs/current/reference/html/#elasticsearch.clients.rest), but it still not work:
#Configuration
public class ElasticsearchConfig {
#Bean(destroyMethod = "close")
public RestHighLevelClient restClient1() {
final CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
RestClientBuilder builder = RestClient.builder(new HttpHost("localhost", 9201));
RestHighLevelClient client = new RestHighLevelClient(builder);
return client;
}
}
How can I config HTTP port (not default port)?

Answer 1

You should use the following code:
#Bean
public RestHighLevelClient elasticsearchClient() {
final ClientConfiguration clientConfiguration = ClientConfiguration.builder()
.connectedTo("localhost:9201")
// if you need basic authentication:
.withBasicAuth("user", "password")
.build();
return RestClients.create(clientConfiguration).rest();
}
Edit:
Check the complete configuration from the docs, when using a custom configuration like this, I'd recommend to not let Spring Boot try to configure Spring Data Elasticsearch. You can do this by changing the annotation on your application class to
#SpringBootApplication(exclude = ElasticsearchDataAutoConfiguration.class)
