六、SpringBoot集成elasticsearch

目录

官网API介绍

1、新建maven项目

2、检查elasticsearch依赖的版本

3、配置RestHighLevelClient对象

4、使用springboot-test测试API的使用

官网API介绍

Java API Client

https://www.elastic.co/guide/en/elasticsearch/client/java-api-client/current/index.html

Java REST Client（rest-high-level-client）：

https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high.html

Java REST Client依赖

<dependency>

    <groupId>org.elasticsearch.client</groupId>

    <artifactId>elasticsearch-rest-high-level-client</artifactId>

</dependency>

使用对象操作es

RestHighLevelClient client = new RestHighLevelClient(

        RestClient.builder(

                new HttpHost("localhost", 9200, "http")));

操作完后关闭连接

client.close();

1、新建maven项目

测试springboot集成elasticsearch的API使用

在新项目的pom文件中添加依赖

<!--导入了elasticsearch依赖-->
<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
</dependency>
<!-- 引入fastjson依赖，发送elasticsearch的请求体时需要将对象转化为json字符串-->
<dependency>
   <groupId>com.alibaba</groupId>
   <artifactId>fastjson</artifactId>
   <version>1.2.62</version>
</dependency>
<!--引入lombok插件依赖，生成实体类的get、set等方法-->
<dependency>
   <groupId>org.projectlombok</groupId>
   <artifactId>lombok</artifactId>
   <optional>true</optional>
</dependency>
<!--引入springboot测试依赖-->
