elasticsearch7.9整合springboot

1、需要添加依赖

2、添加配置文件

package com.example.elasticsearch.shop.configure;
import org.elasticsearch.client.RestHighLevelClient;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.elasticsearch.client.ClientConfiguration;
import org.springframework.data.elasticsearch.client.RestClients;
import org.springframework.data.elasticsearch.config.AbstractElasticsearchConfiguration;
import org.springframework.data.elasticsearch.core.ElasticsearchRestTemplate;

@Configuration
class RestClientConfig extends AbstractElasticsearchConfiguration {
    @Bean
    @Override
    public RestHighLevelClient elasticsearchClient() {
        final ClientConfiguration clientConfiguration = ClientConfiguration.builder()
                .connectedTo("10.138.130.1:30217","10.138.130.1:32002","10.138.130.1:33785")
                .build();

        return RestClients.create(clientConfiguration).rest();
    }
    @Bean(name = { "elasticsearchOperations", "elasticsearchRestTemplate" })
    public ElasticsearchRestTemplate elasticsearchTemplate() {
        return new ElasticsearchRestTemplate(elasticsearchClient());
    }
}

3、创建索引

public Boolean createIndex() {
        return elasticsearchRestTemplate.indexOps(ShopEntity.class).create();
    }

　　

4、创建mapping

  Document mapping = elasticsearchRestTemplate.indexOps(ShopEntity.class).createMapping(ShopEntity.class);
        boolean brue = elasticsearchRestTemplate.indexOps(ShopEntity.class).putMapping(mapping);
        System.out.println(brue);
        System.out.println(mapping);
