org.elasticsearch.client.transport.NoNodeAvailableException

Question

我正在嘗試構建一個簡單的Java程序以將一個簡單的json輸入到elasticsearch中。我正在本機上運行Elasticsearch。 我收到以下錯誤。

這是我嘗試使用Eclipse運行的代碼。

public static void main(String[] args) {
    Settings settings = ImmutableSettings.settingsBuilder().put("cluster.name","prop").build();
    TransportClient transportClient = new TransportClient(settings);
    Client client = new TransportClient().addTransportAddress(new InetSocketTransportAddress("localhost",9200));    

    client.prepareIndex("kod", "article", "2").setSource(putJsonDocument("abhishek sachan", "JSSATE", "Sachan4894", new String[]{"computer"}, "elasticsearch")).execute().actionGet();
}

private static Map<String, Object> putJsonDocument(String title, String content, String postDate, String[] tags, String author) {
    // TODO Auto-generated method stub

    Map<String, Object> jsonDocument = new HashMap<String, Object>();

    jsonDocument.put("title", title);
    jsonDocument.put("conten", content);
    jsonDocument.put("postDate", postDate);
    jsonDocument.put("tags", tags);
    jsonDocument.put("author", author);
    return jsonDocument;
}

傳輸客戶端使用TCP端口，ES的默認端口為9300。 您正在使用9200，這是REST客戶端的HTTP端口。 這樣可以解決您的問題。
