To introduce a jar package:

<dependency>
<groupId>org.elasticsearch</groupId>
<artifactId>elasticsearch</artifactId>
<version>2.4.0</version>
</dependency>

Write Test class:

 Packagecom.sxt.es.test;Importjava.net.InetAddress;Importjava.util.Date;ImportOrg.elasticsearch.action.index.IndexResponse;Importorg.elasticsearch.client.transport.TransportClient;Importorg.elasticsearch.common.transport.InetSocketTransportAddress;Importorg.elasticsearch.common.xcontent.XContentFactory; Public classTestes {Private StaticString host= "192.168.136.131";//Server Address    Private Static intport=9300;//Port         Public Static voidMain (string[] args)throwsException {transportclient client=Transportclient.builder (). Build (). Addtransportaddress (Newinetsockettransportaddress (Inetaddress.getbyname (testes.host), testes.port)); Indexresponse Response=client.prepareindex ("Twitter", "tweet", "1"). SetSource (Xcontentfactory.jsonbuilder (). StartObject () . Field ("User", "Kimchy"). Field ("Postdate",NewDate ()). Field ("Message", "trying out Elasticsearch"). EndObject ()). get (); System.out.println ("Index Name:" +Response.getindex ()); System.out.println ("Type:" +Response.gettype ()); System.out.println ("Document ID:" +response.getid ());//first time use is 1Client.close (); }}
