ElasticSearch: Low Level Client Put

In this tutorial I will show you how to put a json document into ElasticSearch. If you have not first connected to ElasticSearch please do so before continuing.

Imports

import org.apache.http.HttpEntity;
import org.apache.http.nio.entity.NStringEntity;
import org.elasticsearch.client.Response;
import org.apache.http.entity.ContentType;
import org.apache.http.util.EntityUtils;

Now perform the PUT request using the low level client.

final String document = "{\"key\": 1 }";
final HttpEntity httpEntity = new NStringEntity(document, ContentType.APPLICATION_JSON);
final Integer id = 1;
final Response response = restClient.performRequest("PUT", "/indexName/indexType/" + id, Collections.<String, String>emptyMap(), httpEntity);
 
//Now you can print the response
System.out.println(EntityUtils.toString(response.getEntity()));
