我就廢話不多說了，大家還是直接看代碼吧~

/* *es配置類 * */ @Configurationpublic class ElasticSearchDataSourceConfigurer { private static final Logger LOG = LogManager.getLogger(ElasticSearchDataSourceConfigurer.class); @Bean public TransportClient getESClient() { //設置集群名稱 Settings settings = Settings.builder().put('cluster.name', 'bigData-cluster').put('client.transport.sniff', true).build(); //創建client TransportClient client = null; try { client = new PreBuiltTransportClient(settings) .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName(''), 9300));//集群ip LOG.info('ESClient連接建立成功'); } catch (UnknownHostException e) { LOG.info('ESClient連接建立失敗'); e.printStackTrace(); } return client; } }

補充知識：使用java創建ES(ElasticSearch)連接池

1.首先要有一個創建連接的工廠類

package com.aly.util; import org.apache.commons.pool2.PooledObject;import org.apache.commons.pool2.PooledObjectFactory;import org.apache.commons.pool2.impl.DefaultPooledObject;import org.apache.http.HttpHost;import org.elasticsearch.client.RestClient;import org.elasticsearch.client.RestHighLevelClient; /** * EliasticSearch連接池工廠對象 * @author 00000 * */public class EsClientPoolFactory implements PooledObjectFactory<RestHighLevelClient>{ @Overridepublic void activateObject(PooledObject<RestHighLevelClient> arg0) throws Exception {System.out.println('activateObject');}/** * 銷毀對象 */@Overridepublic void destroyObject(PooledObject<RestHighLevelClient> pooledObject) throws Exception {RestHighLevelClient highLevelClient = pooledObject.getObject();highLevelClient.close();}/** * 生產對象 *///@SuppressWarnings({ 'resource' })@Overridepublic PooledObject<RestHighLevelClient> makeObject() throws Exception {//Settings settings = Settings.builder().put('cluster.name','elasticsearch').build();RestHighLevelClient client = null;try {/*client = new PreBuiltTransportClient(settings) .addTransportAddress(new TransportAddress(InetAddress.getByName('localhost'),9300));*/client = new RestHighLevelClient(RestClient.builder(new HttpHost('192.168.1.121', 9200, 'http'), new HttpHost('192.168.1.122', 9200, 'http'),new HttpHost('192.168.1.123', 9200, 'http'), new HttpHost('192.168.1.125', 9200, 'http'),new HttpHost('192.168.1.126', 9200, 'http'), new HttpHost('192.168.1.127', 9200, 'http'))); } catch (Exception e) {e.printStackTrace();}return new DefaultPooledObject<RestHighLevelClient>(client);} @Overridepublic void passivateObject(PooledObject<RestHighLevelClient> arg0) throws Exception {System.out.println('passivateObject');} @Overridepublic boolean validateObject(PooledObject<RestHighLevelClient> arg0) {return true;}}

2.然后再寫我們的連接池工具類

package com.aly.util; import org.apache.commons.pool2.impl.GenericObjectPool;import org.apache.commons.pool2.impl.GenericObjectPoolConfig;import org.elasticsearch.client.RestHighLevelClient; /** * ElasticSearch 連接池工具類 * * @author 00000 * */public class ElasticSearchPoolUtil {// 對象池配置類，不寫也可以，采用默認配置private static GenericObjectPoolConfig poolConfig = new GenericObjectPoolConfig();// 采用默認配置maxTotal是8，池中有8個clientstatic {poolConfig.setMaxTotal(8);}// 要池化的對象的工廠類，這個是我們要實現的類private static EsClientPoolFactory esClientPoolFactory = new EsClientPoolFactory();// 利用對象工廠類和配置類生成對象池private static GenericObjectPool<RestHighLevelClient> clientPool = new GenericObjectPool<>(esClientPoolFactory,poolConfig); /** * 獲得對象 * * @return * @throws Exception */public static RestHighLevelClient getClient() throws Exception {// 從池中取一個對象RestHighLevelClient client = clientPool.borrowObject();return client;} /** * 歸還對象 * * @param client */public static void returnClient(RestHighLevelClient client) {// 使用完畢之后，歸還對象clientPool.returnObject(client);}}

以上這篇java連接ElasticSearch集群操作就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支持好吧啦網。
