Spring Data ElasticSearch - 无法连接到节点

我尝试在Spring MVC应用程序中配置ElasticSearch存储库。我使用Spring Data ElasticSearch版本：2.0.7和ElasticSearch Server 2.4.4。Spring Data ElasticSearch - 无法连接到节点

我敢肯定，ElasticNode工作，这里是样本输出

$ 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" 
}

这里是我的测试配置

@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; 

} 
}

我得到的错误，应用程序无法连接到弹性节点，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...

我试图从1.7.1,2.4.4更改弹性搜索节点的版本和5.2.1。什么都没有 Spring MVC的4.3.6.RELEASE与Java 8

简而言之：ElasticSearch节点和TransportClient应具有相同的版本。

Spring Data ElasticSearch在版本2.2.0中提供了TransportClient。我在2.4.4版本中使用了ElasticSearch节点。我将ES节点降级到2.2.0，并将配置中的端口从9200更改为9300。

你是对的。很高兴我没有遇到与TransportClient版本有关的问题。仍然很好知道未来。但是我有很多问题，因为我不了解9200和9300默认端口。这里是讨论何时使用哪一个帮助我：http://elasticsearch-users.115913.n3.nabble.com/Transport-Client-VS-REST-Client-td4042497.html – RenatoIvancic

的Transport client会谈elasticsearch通过端口9300。因此，尝试

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