41-Springboot整合HignLevelClient----给es中保存数据

1、导入依赖

		<dependency>
			<groupId>org.elasticsearch.client</groupId>
			<artifactId>elasticsearch-rest-high-level-client</artifactId>
			<version>7.4.2</version>
		</dependency>

2、编写配置类

package com.elasticsearcj.config;

import org.apache.http.HttpHost;
import org.elasticsearch.client.RequestOptions;
import org.elasticsearch.client.RestClient;
import org.elasticsearch.client.RestClientBuilder;
import org.elasticsearch.client.RestHighLevelClient;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class GulimallElasticsearchConfig {

    public static final RequestOptions COMMON_OPTIONS;
    static {
        RequestOptions.Builder builder = RequestOptions.DEFAULT.toBuilder();
        COMMON_OPTIONS = builder.build();
    }

    @Bean
    public RestHighLevelClient client(){
        RestClientBuilder builder = RestClient.builder(new HttpHost("192.168.56.10", 9200, "http"));

        return new RestHighLevelClient(builder);
    }
}
