ElasticSearch: High Level Client Post

In this tutorial I will show you how to perform a POST request. If you have not connected first please do so before continuing.

Imports

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

Now we can perform the POST to ElasticSearch.

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