elasticsearch - Spring Data ElasticSearch-无法连接到节点

Question

我正在尝试在Spring MVC应用程序中配置ElasticSearch存储库。
我正在使用Spring Data ElasticSearch版本:2.0.7和ElasticSearch Server 2.4.4。

我确定ElasticNode可以正常工作，这是示例输出

$ curl -X GET http://127.0.0.1:9200/
{
  "name" : "Tattoo",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "dX0lPfNnSA6vxGqhzVEuSg",
  "version" : {
    "number" : "2.4.4",
    "build_hash" : "fcbb46dfd45562a9cf00c604b30849a6dec6b017",
    "build_timestamp" : "2017-01-03T11:33:16Z",
    "build_snapshot" : false,
    "lucene_version" : "5.5.2"
  },
  "tagline" : "You Know, for Search"
}

这是我的测试配置

@Configuration
@EnableElasticsearchRepositories(basePackages = "com.somepackage.repo.elastic")
public class ElasticSearchConfig {

@Bean
public ElasticsearchTemplate elasticsearchTemplate() throws UnknownHostException {
    return new ElasticsearchTemplate(nodeClient());
}

@Bean
public TransportClient nodeClient() throws UnknownHostException {

    Settings settings = Settings.builder().put("cluster.name", "elasticsearch").build();
    TransportClient client = TransportClient.builder()
            .settings(settings)
            .build();
    client.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9200));
    return client;

}
}

我收到应用程序无法连接到 flex 节点的错误，堆栈跟踪

2017-02-17 23:34:53 INFO  transport:383 - [Impulse] failed to get node info for {#transport#-1}{127.0.0.1}{localhost/127.0.0.1:9200}, disconnecting...

我试图将 flex 搜索节点的版本从1.7.1、2.4.4和5.2.1更改。没事。
使用Java 8的Spring MVC 4.3.6.RELEASE

Answer 1

Transport client通过端口9300与elasticsearch对话。因此，请尝试

client.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));
