springboot集成ElasticSearch7.7.1

pom.xml導入坐標

<!--ES-->
<dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
</dependency>
注意是這個版本

spring.yml配置

spring:  
 elasticsearch:
     rest:
       uris: http://127.0.0.1:9200

 導入模板就可以用了

@Autowired
private ElasticsearchRestTemplate esTemplate;
