spring-boot - 使用 Spring Boot 连接到 Elasticsearch 6.2.3

Question

试图弄清楚如何让 spring boot 的工作配置连接到 Elasticsearch 6.2.3，这是我的连接代码:

pom.xml:

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
        <version>2.0.1.RELEASE</version>
    </dependency>

还有我的连接代码:

import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.common.settings.Settings;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.elasticsearch.core.ElasticsearchTemplate;
import java.net.UnknownHostException;


@Configuration
public class ElasticsearchConfig {

@Bean
public ElasticsearchTemplate elasticsearchTemplate() throws 
UnknownHostException {

    Settings settings = Settings.builder()
            .put("client.transport.sniff", true).build();

    // Can't resolve symbol "PreBuiltTransportClient" 
    TransportClient client = new PreBuiltTransportClient(settings);

    return new ElasticsearchTemplate(client);

}

现在您可以使用 6.x。无论如何，您可以在此处查看支持的版本:https://docs.spring.io/spring-data/elasticsearch/docs/3.2.0.RC3/reference/html/#preface.versions
