创建索引

1，首先我们要有已经搭建好的Elasticsearch 并且是没问题的！

废话不多说直接上代码了

import com.google.gson.Gson;import org.elasticsearch.action.index.IndexRequestBuilder;import org.elasticsearch.action.index.IndexResponse;import org.elasticsearch.client.transport.TransportClient;import org.elasticsearch.common.settings.Settings;import org.elasticsearch.common.transport.InetSocketTransportAddress;import org.elasticsearch.rest.RestStatus;import org.elasticsearch.transport.client.PreBuiltTransportClient;import org.junit.After;import org.junit.Before;import org.junit.Test;import java.io.IOException;import java.net.InetAddress;import java.net.UnknownHostException;import java.util.HashMap;import java.util.Map;//import org.springframework.data.elasticsearch.core.ElasticsearchTemplate;/** * Created by 启才 on 2017/4/25. */public class BookRepositoryTest {    TransportClient client;    @Before    public void setup() throws UnknownHostException {        System.out.println("create TransportClient...");        client = new PreBuiltTransportClient(Settings.EMPTY)                .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("....."), 9300));    }    @After    public void clearup() {        System.out.println("close TransportClient...");        if (client != null) {            client.close();        }    }    @Test    public void doIndex() throws IOException {        Gson gson = new Gson();        Map map = new HashMap();        map.put("title", "hello test");        map.put("description", "你好世界");        map.put("price", 25.3);        map.put("onSale", "asdasdasda");        map.put("type", "testtypesssss");        map.put("createDate", "2017.0000");        String json = gson.toJson(map);        IndexRequestBuilder indexRequestBuilder = client.prepareIndex("wang", "test", "10").setSource(json);        IndexResponse response = indexRequestBuilder.get();        // Index name        String _index = response.getIndex();// Type name        String _type = response.getType();// Document ID (generated or not)        String _id = response.getId();// Version (if it's the first time you index this document, you will get: 1)        long _version = response.getVersion();// status has stored current instance statement.        RestStatus status = response.status();    }}

我们会发现这种创建方式与其他版本的创建方式有那么一点不同，尤其是创建client的时候！

并不是所有的创建方式都是一样的！

创建完成后我们可以通过kibana来查看

过几天我还会有ES的 JAVA API 的各种查询希望能帮助大家！
