ElasticSearch —— 整合springboot(二)

首先保證elasticsearch、kibana 跑起來之後，再初始化一個springboot基礎空項目，能跑起來就可以了。

import org.springframework.data.elasticsearch.repository.config.EnableElasticsearchRepositories;

@SpringBootApplication
@EnableElasticsearchRepositories(basePackages = "com.example.test_three.repository")
public class TestThreeApplication {

   public static void main(String[] args) {
      SpringApplication.run(TestThreeApplication.class, args);
   }

}

項目跑起來之後就可以測試了，我們通常都是使用postman測試接口的

備註一下：9300與9200的區別

    9300端口：ES節點之間通訊使用  。是TCP協議端口號，ES集羣之間通訊端口號

    9200端口：ES節點  和 外部通訊使用。是端口號，暴露 ES  RESTFul 接口端口號
