ElasticSearch: Low Level Rest Client Connection

In this tutorial I will show you how to use the ElasticSearch low level rest client.

First you will need to add the low level rest to the pom.

<properties>
	<elasticSearch.version>6.2.4</elasticSearch.version>
</properties>
 
<dependency>
    <groupId>org.elasticsearch.client</groupId>
    <artifactId>elasticsearch-rest-client</artifactId>
    <version>${elasticSearch.version}</version>
</dependency>

Next you will need to specify the imports.

import org.apache.http.HttpHost;
import org.elasticsearch.client.Response;
import org.elasticsearch.client.RestClient;
import org.elasticsearch.client.RestClientBuilder;

Now you can connect to ElasticSearch.

final RestClientBuilder restClientBuilder = RestClient.builder(new HttpHost("localhost", 9200, "http"));
 
final RestClient restClient = builder.build();

Now you can do whatever you need to!
