Question

我对弹性搜索概念很陌生。我正在尝试使用弹性搜索构建一个简单的应用程序。

public class App 
{
public static void main( String[] args )
{
    try {
        TransportClient client = new PreBuiltTransportClient(Settings.EMPTY)
                .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));

        ElasticOperations.addDocToIndex(client, ElasticUtility.getJsonMap("Sandesha", "male", "jsandesh08@gmail.com", "Hassan"));
        System.out.println("Doc added");
        client.close();
    } catch (UnknownHostException e) {

        e.printStackTrace();
    }

}
}

但是，当试图运行此程序时，我得到NoNodeAvailableException。

线程中的异常＆＃34; main＆＃34; NoNodeAvailableException [没有配置的节点可用：[{＃transport＃-1} {w1bSLAN-TFWUHE1PA3qDeQ} {localhost} {127.0.0.1：9300}]] at org.elasticsearch.client.transport.TransportClientNodesService.ensureNodesAreAvailable（TransportClientNodesService.java:347） at org.elasticsearch.client.transport.TransportClientNodesService.execute（TransportClientNodesService.java:245）在org.elasticsearch.client.transport.TransportProxyClient.execute（TransportProxyClient.java:59） at org.elasticsearch.client.transport.TransportClient.doExecute（TransportClient.java:363）在org.elasticsearch.client.support.AbstractClient.execute（AbstractClient.java:408）在org.elasticsearch.action.ActionRequestBuilder.execute（ActionRequestBuilder.java:80）在org.elasticsearch.action.ActionRequestBuilder.execute（ActionRequestBuilder.java:54） at com.sandesha.elasticsearch.Elastic.ElasticOperations.addDocToIndex（ElasticOperations.java:11）在com.sandesha.elasticsearch.Elastic.App.main（App.java:27）

请帮我解决这个问题。我的ElasticOperations课程是，

public class ElasticOperations {

public static void addDocToIndex(TransportClient client, Map<String,Object> jsonMap)
{
    client.prepareIndex("customers", "personal").setSource(jsonMap).execute().actionGet();
}

}

我的ElasticUtility课程看起来像，

public class ElasticUtility {

public static Map<String, Object> getJsonMap(String name, String gender, String email, String city)
{
    Map<String,Object> jsonMap = new HashMap<String, Object>();
    jsonMap.put("name", name);
    jsonMap.put("gender", gender);
    jsonMap.put("email", email);
    jsonMap.put("city", city);

    return jsonMap;
}
}

谢谢。

我认为你的群集名称不匹配。如果您的群集名称不是“弹性搜索”，则可能是问题。

在浏览器中转到http://localhost:9200并获取群集名称。然后，尝试将群集名称属性添加到TransportClient，如下所示：

Settings settings = Settings.builder()
                            .put("cluster.name", "elasticsearch_foo").build();
TransportClient client = new PreBuiltTransportClient(settings)
                         .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));

弹性搜索中没有节点可用异常
