通过TransportClient在java中使用Elasticsearch

我试图通过TransportClient在java中使用elasticsearch。我使用logstash将mysql与elasticsearch集成。 这就是我初始化和使用传输客户端的方式

TransportClient client = new PreBuiltTransportClient(Settings.EMPTY).addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"),9200));

我无法连接到节点，并且我得到了握手超时。 我得到以下错误：

TransportClientNodesService - failed to connect to node 
[{#transport#-1}{vrvVU4MGTAC7_5NCOiBseg}{localhost}{127.0.0.1:9200}], 
ignoring...

Elasticsearch传输端口为

9300

，因此请更改客户端创建行，将9200替换为

9300

，如下所示：

TransportClient client = new PreBuiltTransportClient(Settings.EMPTY).addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"),9300));

Settings settings = Settings.builder()
        .put("cluster.name", "myClusterName").build();
TransportClient client = new PreBuiltTransportClient(settings);
//Add transport addresses and do something with the client...

查找相关文档

如果您使用的是不同的

cluster.name

，而不是默认值（

elasticsearch

），则必须在创建TransportClient时进行设置，如下所示：

TransportClient client = new PreBuiltTransportClient(Settings.EMPTY).addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"),9300));

Settings settings = Settings.builder()
        .put("cluster.name", "myClusterName").build();
TransportClient client = new PreBuiltTransportClient(settings);
//Add transport addresses and do something with the client...

我应该在logstash.conf文件和其他地方将端口更改为9300还是仅在此处？仅在上面一行中。将错误获取为“不属于群集[elasticsearch]，忽略…”是否已配置不同的

群集。名称

然后必须向传输客户端提供群集名称。你可以在这里找到设置集群名称的代码[是的，我已经解决了这个问题。非常感谢。我在这里找到了解决方案。
