正确使用TransportClient进行弹性搜索

Question

我有一个问题,创建用于弹性搜索的TransportClient bean,compiller它说构造函数是私有的,就像那样.我怎样才能正确创建bean？这是我的配置类:

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());
}

}

弹性搜索依赖性是:elasticsearch-2.4.2

API已经改变了!请注意您使用的版本.

从版本5.5传输客户端:

TransportClient client = new PreBuiltTransportClient(Settings.EMPTY)

请注意,如果使用不同于"elasticsearch"的群集名称,则必须设置群集名称:

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