使用java客户端创建索引库

package com.hope.es;

import org.elasticsearch.client.transport.TransportClient;import org.elasticsearch.common.settings.Settings;import org.elasticsearch.common.transport.InetSocketTransportAddress;import org.elasticsearch.transport.client.PreBuiltTransportClient;import org.junit.Test;

import java.net.InetAddress;

/** * 创建索引库 * @author newcityman * @date 2020/1/16 - 18:24 */public class ElasticSearchClient {    @Test    public void createIndex() throws Exception{        //1、创建一个setting对象，相当于一个配置信息，主要配置集群的名称        Settings settings = Settings.builder()                .put("cluster.name", "my‐elasticsearch").build();        //2、创建一个客户端client对象        TransportClient client = new PreBuiltTransportClient(settings);        client.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("127.0.0.1"),9301));        client.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("127.0.0.1"),9302));        client.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("127.0.0.1"),9303));        //3、使用client对象，创建一个索引库        client.admin().indices().prepareCreate("index_hello").get();        //4、关闭client对象        client.close();    }}
