**1. 創建一個Maven項目** ```xml <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.3.6.RELEASE</version> <relativePath /> </parent> <groupId>com.atguigu.elasticsearch</groupId> <artifactId>elasticsearch-springdata</artifactId> <version>1.0</version> <properties> <maven.compiler.source>8</maven.compiler.source> <maven.compiler.target>8</maven.compiler.target> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-elasticsearch</artifactId> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <scope>runtime</scope> <optional>true</optional> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-test</artifactId> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> </dependency> </dependencies> ``` **2. `resources/application.properties`** ``` # es 服務地址 elasticsearch.host=http://127.0.0.1 # es 服務端口 elasticsearch.port=9200 # 配置日志級別,開啟 debug 日志 logging.level.com.learn.es02=debug ``` **3. 配置RestHighLevelClient客戶端** ```java @Data @Configuration @ConfigurationProperties(prefix = "elasticsearch") public class ElasticsearchConfig extends AbstractElasticsearchConfiguration { private String host; private Integer port; @Override public RestHighLevelClient elasticsearchClient() { RestClientBuilder builder = RestClient.builder(new HttpHost(host, port)); RestHighLevelClient restHighLevelClient = new RestHighLevelClient(builder); return restHighLevelClient; } } ``` **4. 到這里就搭建完了，可以繼續后面的操作了**
