Question

我正在尝试实现Elasticsearch API。我在系统接受nodeBuilder时遇到错误。这是代码 -

import org.elasticsearch.action.index.IndexResponse;   
import org.elasticsearch.action.update.UpdateRequest;
import org.elasticsearch.client.Client;
//import org.elasticsearch.common.settings.ImmutableSettings; 
import org.elasticsearch.common.settings.*;
import org.elasticsearch.ElasticsearchException; 
import org.elasticsearch.action.search.SearchResponse; 
import org.elasticsearch.action.search.SearchType; 
import org.elasticsearch.client.transport.TransportClient; 
import   org.elasticsearch.node.NodeBuilder.*;
import org.elasticsearch.common.settings.Settings;
import org.elasticsearch.common.transport.InetSocketTransportAddress; 
import org.elasticsearch.common.unit.TimeValue; 
import org.elasticsearch.index.query.QueryBuilders; 
import org.elasticsearch.search.SearchHit; 



    // on startup

    Node node = nodeBuilder().node(); // nodeBuilder not recognised.
    Client client = node.client();

    // on shutdown

    node.close();


<dependency>
    <groupId>org.elasticsearch</groupId>
    <artifactId>elasticsearch</artifactId>
    <version>2.2.0</version>
</dependency>

客户得到认可。有什么想法吗？

ES API 5中删除了

ClientBuilder。

您可以使用org.elasticsearch.common.settings.Settings.builder()，它会为您提供Builder的实例。

Exp：

Settings.Builder elasticsearchSettings =
                Settings.builder()
                        .put("http.enabled", "true") 
                        .put("index.number_of_shards", "1")
                        .put("path.data", new File(tmpDir, "data").getAbsolutePath()) 
                        .put("path.logs", new File(tmpDir, "logs").getAbsolutePath()) 
                        .put("path.work", new File(tmpDir, "work").getAbsolutePath()) 
                        .put("path.home", tmpDir);

Answer 2

NodeBuilder已被删除。虽然直接在应用程序中使用Node不受官方支持，但它仍然可以使用Node（Settings）构造函数构建。请参阅 - https://www.elastic.co/guide/en/elasticsearch/reference/5.5/breaking_50_java_api_changes.html

Answer 3

    org.elasticsearch.node.Node node =      org.elasticsearch.node.NodeBuilder.nodeBuilder().node();

我还有一些使用节点的依赖项，因此系统无法解析弹性搜索。资格证明了它。

在ElasticSearch API应用程序中找不到NodeBuilder
