Can'；t使用Java API连接到ElasticSearch服务器

Can'；t使用Java API连接到ElasticSearch服务器,java,elasticsearch,Java,elasticsearch,我正在尝试使用Java API连接到ElasticSearch服务器。我使用elasticsearch服务启动/停止，并使用elasticsearch头部可视化集群。集群/节点处于活动状态，RESTAPI通过9200上的curl正常工作。我已经阅读了几乎所有关于这个主题的帖子，但我无法让它工作，以下是我的详细信息：所有这些我都试过了： Settings settings = ImmutableSettings.settingsBuilder().put("cluster.name", "tes

我正在尝试使用Java API连接到ElasticSearch服务器。我使用elasticsearch服务启动/停止，并使用elasticsearch头部可视化集群。集群/节点处于活动状态，RESTAPI通过9200上的curl正常工作。我已经阅读了几乎所有关于这个主题的帖子，但我无法让它工作，以下是我的详细信息：

所有这些我都试过了：

Settings settings = ImmutableSettings.settingsBuilder().put("cluster.name", "test").put("node.name", "inventory_management").build();
Client client = new TransportClient(settings).addTransportAddress(new InetSocketTransportAddress("localhost", 9300));
IndexResponse response = client.prepareIndex("twitter", "tweet", "1").setSource(json).execute().actionGet();

使用localhost、devhost1127.0.0.1或TransportClient中网络上的实际IP

在config.yaml中取消对IP属性的注释并放置127.0.0.1（服务器）

检查端口9300是否可用，则为

问题已按以下方式解决。确保您的客户端和服务器版本同步

正因为如此，这个问题被标记为“为可能遇到相同问题的其他人解答”（答案实际上在问题的末尾）

我遇到了同样的问题，结果是Java客户机使用的JAR版本与服务器运行的版本之间存在差异。你最好的办法是确保精确匹配，然后给出的指令在没有任何调整的情况下工作

另一件需要检查的事情是，您的Java客户机使用的端口是否正确，而http客户机使用的端口不是正确的端口。正确的端口默认为9300，而不是9200，后者使用9200。

如果其他人偶然发现此线程，我发现您可能收到此错误的另一个原因是因为

群集名称已更改为默认名称以外的内容
要查看您当前的群集名称
：
curl -XGET localhost:9200/_cluster/nodes?pretty=true

使用类似于OP上面的代码：
Settings settings = ImmutableSettings.settingsBuilder()
    .put("cluster.name", "test").build();
Client client = new TransportClient(settings).addTransportAddress(new InetSocketTransportAddress("localhost", 9300));

来源：
这是为使用spring boot spring data elasticsearch的用户提供的。请确保客户端的版本与服务器的版本相同
<library name="Gradle: org.elasticsearch:elasticsearch:1.5.2">
  <CLASSES>
    <root url="jar://$USER_HOME$/.gradle/caches/modules-2/files-2.1/org.elasticsearch/elasticsearch/1.5.2/47aafc6bf8f23ed8dcbf6a1db174fb0b8e44a8db/elasticsearch-1.5.2.jar!/" />

  </SOURCES>
</library>

首先，版本非常重要，Java API与您使用的版本密切相关
此解决方案适用于ElasticSearchV5.4.1和Java8
确保您正在获取所有依赖项，以及子依赖项（不仅仅是elasticSearch jar），使用maven、ivy等获取依赖项树
以常春藤为例：
 <!-- https://mvnrepository.com/artifact/org.elasticsearch.client/transport -->
  <dependency org="org.elasticsearch.client" name="transport" rev="5.4.1"  conf="default"/>

我认为问题可能与您的计算机上有多个网络设备有关。您正在本地计算机上同时运行客户端和服务器，对吗？否则，使用多播是一个发现问题…有防火墙吗？什么操作系统？您好，是的，两个都在同一台机器上运行（LINUX/Kubuntu）。没有防火墙…只有一个网络设备。您是否尝试过使用更明确的单播群集发现而不是多播自动发现？正如您所知，发现时的初始ping使用9300端口，但使用udp而不是tcp。同样，这类问题通常是由防火墙引起的。我肯定会尝试单播，而不是@mconlin所说的多播发现。
