正確使用TransportClient進行Elasticsearch

Question

我創建TransportClient bean進行彈性搜索時遇到問題，編譯器說構造函數是私有的，就是這樣。 我如何正確創建bean？ 這是我的配置類：

import org.elasticsearch.client.Client;
import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.common.transport.InetSocketTransportAddress;
import org.elasticsearch.common.transport.TransportAddress;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.elasticsearch.core.ElasticsearchOperations;
import org.springframework.data.elasticsearch.core.ElasticsearchTemplate;
import org.springframework.data.elasticsearch.repository.config.EnableElasticsearchRepositories;

@Configuration
@EnableElasticsearchRepositories(basePackages = "example.spring.data.es.repository")
@ComponentScan(basePackages = { "example.spring.data.es.service" })
public class Config {

@Bean
public Client client() {
//here compiller says that the TransportClient() is private. How else i cna create the transport client?
    TransportClient client = new TransportClient();

    TransportAddress address = new InetSocketTransportAddress(
            "localhost",9200);
    client.addTransportAddress(address);
    return client;
}

@Bean
public ElasticsearchOperations elasticsearchTemplate() {
    return new ElasticsearchTemplate(client());
}

}

彈性搜索依賴性為：elasticsearch-2.4.2

Answer 1

API已更改！ 使用的版本要小心。

從5.5版傳輸客戶端 ：

TransportClient client = new PreBuiltTransportClient(Settings.EMPTY)

請注意，如果使用與“ elasticsearch”不同的名稱，則必須設置集群名稱：

Settings settings = Settings.builder().put("cluster.name", "myClusterName").build();
TransportClient client = new PreBuiltTransportClient(settings);

Answer 2

您需要使用提供的構建器方法進行初始化。 例：

TransportClient client = TransportClient.builder().build();
