八、SpringBoot集成ES

文档

1.导入依赖

<dependency>
    <groupId>org.elasticsearch.client</groupId>
    <artifactId>elasticsearch-rest-high-level-client</artifactId>
    <version>7.9.1</version>
</dependency>

2.构建对象

创建项目

配置基本的项目
问题：一定要保证，我们导入的依赖和我们的es版本一致

编写配置类

@Configuration
public class ElasticSearchClientConfig {
    @Bean
    public RestHighLevelClient restHighLevelClient(){
        RestHighLevelClient client = new RestHighLevelClient(
                RestClient.builder(
                        new HttpHost("localhost", 9200, "http")));
        return client;
    }
}
