Elasticsearch Java Client版本区别及起步是什么

这期内容当中小编将会给大家带来有关Elasticsearch Java Client版本区别及起步是什么，文章内容丰富且以专业的角度为大家分析和叙述，阅读完这篇文章希望大家可以有所收获。

简单总结：

• 如果服务端是5.6以下的，选择相同版本的TransportClient，避免一些API服务端不支持

• 如果服务端是5.6以上的，选择相同版本的RestClient

TransportClient起步：

5.6及之前的版本：

// on startupClient client = TransportClient.builder().build()        .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("host1"), 9300))        .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("host2"), 9300));// on shutdownclient.close();

6.0及之后的版本：

// on startupTransportClient client = new PreBuiltTransportClient(Settings.EMPTY)        .addTransportAddress(new TransportAddress(InetAddress.getByName("host1"), 9300))        .addTransportAddress(new TransportAddress(InetAddress.getByName("host2"), 9300));// on shutdownclient.close();

TransportClient发送搜索请求：

SearchResponse response = client.prepareSearch("index1", "index2")        .setTypes("type1", "type2")        .setSearchType(SearchType.DFS_QUERY_THEN_FETCH)        .setQuery(QueryBuilders.termQuery("multi", "test"))                 // Query        .setPostFilter(QueryBuilders.rangeQuery("age").from(12).to(18))     // Filter        .setFrom(0).setSize(60).setExplain(true)        .get();

HttpClient起步：

//  Java Low Level REST ClientRestClient lowLevelRestClient = RestClient.builder(        new HttpHost("localhost", 9200, "http"),        new HttpHost("localhost", 9201, "http")).build();// Java High Level REST ClientRestHighLevelClient client = new RestHighLevelClient(lowLevelRestClient);

HttpClient发送搜索请求：

SearchRequest searchRequest = new SearchRequest();searchRequest.source(sourceBuilder);SearchResponse searchResponse = client.search(searchRequest);
