In the afternoon try to use Elasticsearch Java client to do data retrieval work, test the batch update, the code is as follows: Public Static voidBulkupdategoods (listthrowsIOException, Interruptedexception, executionexception {client client=NULL; Try{Client=Transportclient.builder (). Build (). Addtransportaddress (NewInetsockettransportaddress (Inetaddress.getbyname ("Hadoop-slave4"), 9300)); } Catch(Exception e) {e.printstacktrace (); } Bulkrequest
Elasticsearch service.Index on the Elasticsearch server, the first step is to create a connection to the server.Client client = TransportClient.builder().build() .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("127.0.0.1"), 9300));
2. Create a querybuilder.QueryBuilder you can set a query for a single field, or you can set up multiple fields.e.g.1: Query hibernate The document containing the keyword in the title
