我正在尝试点击链接，因为我正在使用 ELasticSearch1.6.0但它正在使用 NodeClient 并且我想使用transportClient但我遇到了异常

 org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are available: []
[info]   at org.elasticsearch.client.transport.TransportClientNodesService.ensureNodesAreAvailable(TransportClientNodesService.java:305)

这是代码

class ElasticsearchServer {
  val log = LoggerFactory.getLogger(this.getClass)
  private val clusterName = "testcluster"
  private val dataDir = Files.createTempDirectory("elasticsearch_test_data_").toFile
  private val settings = ImmutableSettings.settingsBuilder
    .put("path.data", dataDir.toString)
    .put("cluster.name", clusterName)
    .put("node.local",true)
    .build

  def client: TransportClient ={
    val client=new TransportClient(settings)
    .addTransportAddress(new InetSocketTransportAddress("127.0.0.1", 9300))
   client
  }
  def stop(): Unit = {
    client.close();

    try {
      FileUtils.forceDelete(dataDir)
    } catch {
      case e: Exception => // dataDir cleanup failed
    }
  }

    def createAndWaitForIndex(index: String): Unit = {
      client.admin.indices.prepareCreate(index).execute.actionGet()
      client.admin.cluster.prepareHealth(index).setWaitForActiveShards(1).execute.actionGet()
    }
}

class CampaignTestSearch extends PlaySpec{
  val server = new ElasticsearchServer
  server.createAndWaitForIndex("arteciatetestdb")
val client=server.client

val response = client.prepareSearch("dbtest")
      .setTypes(CAMPAIGN_COLLECTION_NAME)
      .setSearchType(SearchType.DFS_QUERY_THEN_FETCH)
      .addFields("uuid","campaignName","artworkID","activationDate","_source")
      .setQuery(query)
      .execute()
      .actionGet()
  }

首先，您需要记住，较新版本的 elasticsearch 已放弃使用嵌入的支持，原因在此博客文章中进行了描述。

在包括 elastic 5 在内的许多 Elasticsearch 版本上，您可以使用 ESIntegTestCase 支持类并使您的集成测试类扩展它，以便在测试中支持嵌入式 Elasticsearch。您可以在他们的官方文档中阅读更多相关信息。

从他们的官方文档中：

public class Mytests extends ESIntegTestCase {

  @Override
  protected Settings nodeSettings(int nodeOrdinal) {
      return Settings.builder().put(super.nodeSettings(nodeOrdinal))
             .put("node.mode", "network")
             .build();
  }

}

在 1.x 版本中，有一个名为 ElasticsearchTestCase 的类可以支持使用弹性进行单元测试，请查看官方存储库上的此链接以获取有关如何使用它的完整示例。

不再支持嵌入式弹性搜索

你可以使用这个 maven 依赖，它会为你启动 elasticsearch 6 集群

<dependency>
    <groupId>org.elasticsearch-6</groupId>
    <artifactId>elasticsearch-embedded-cluster</artifactId>
    <version>1.0-SNAPSHOT</version>
</dependency>

您可以在https://github.com/nitishgoyal13/elasticsearch-6-embedded-cluster上阅读更多详细信息
