1.安装7.6.2的es

访问地址+端口显示如下表示安装成功。
在这里插入图片描述

2.加入maven依赖，在properties中制定版本号

<properties>
    <java.version>1.8</java.version>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <spring-boot.version>2.3.7.RELEASE</spring-boot.version>
        <elasticsearch.version>7.6.2</elasticsearch.version>
</properties>
        <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
    </dependency>

3.创建es的连接配置类

@Configuration
public class ElasticsearchConfig {
   
   

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

4.一些简单的es操作测试

注解注入es类

 @Autowired
 private RestHighLevelClient restHighLevelClient;

添加索引值

    @Test
    void testIndex() throws IOException {
   
   
        CreateIndexRequest request = new CreateIndexRequest("d_index");

        CreateIndexResponse createIndexResponse= restHighLevelClient.indices().create(request, RequestOptions.DEFAULT);

    }

判断索引是否添加成功，返回true代表存在索引。

    @Test
    void testExitIndex() throws IOException {
   
   
        GetIndexRequest request = new GetIndexRequest("d_index");

        boolean exits=
                restHighLevelClient.indices().exists(request, RequestOptions.DEFAULT);
        System.out.println(exits);
    }

删除索引

    @Test
    void testdelIndex() throws IOException {
   
   
        DeleteIndexRequest request = new DeleteIndexRequest("d_index");

        AcknowledgedResponse delete =restHighLevelClient.indices().delete(request, RequestOptions.DEFAULT);
        System.out.println(delete.isAcknowledged());
    }
