SpringBoot+ElasticSearch实现

模糊查询批量CRUD排序分页

一、导入elasticsearch依赖

在pom.xml里加入如下依赖

.

dependency

.

.

groupIdorg.springframework.boot/groupId

.

.

artifactIdspring-boot-starter-data-elasticsearch/artifactId

.

.

/dependency

.

非常重要：检查依赖版本是否与你当前所用的版本是否一致，如果不一致，会连

接失败！

二、创建高级客户端

.

importorg.apache.http.HttpHost;

.

.

importorg.elasticsearch.client.RestClient;

.

.

importorg.elasticsearch.client.RestHighLevelClient;

.

.

importorg.springframework.context.annotation.Bean;

.

.

importorg.springframework.context.annotation.Configuration;

.

.

.

.

@Configuration

.

.

publicclassElasticSearchClientConfig{

.

.

@Bean

.

.

publicRestHighLevelClientrestHighLevelClient(){

.

.

RestHighLevelClientclientnewRestHighLevelClient(

.

.

RestClient.builder(

.

.

newHttpHost(服务器IP,9200,http)));

.

.

returnclient;

.

.

}

.

.

}

.

三、基本用法

1.创建、判断存在、删除索引

.

importorg.elasticsearch.action.admin.indices.delete.DeleteIndexReque

st;

.

.

importorg.elasticsearch.action.support.master.AcknowledgedResponse;

.

.

importorg.elasticsearch.client.RequestOptions;

.

.

importorg.elasticsearch.client.RestHighLevelClient;

.

.

importorg.elasticsearch.client.indices.CreateIndexRequest;

.

.

importorg.elasticsearch.client.indices.CreateIndexResponse;

.

.

importorg.elasticsearch.client.indices.GetIndexRequest;

.

.

importorg.junit.jupiter.api.Test;

.

.

importorg.springframework.beans.factory.annotation.Autowired;

.

.

importorg.springframework.boot.test.context.SpringBootTest;

.

.

.

.

importjava.io.IOException;

.

.

.

.

@SpringBootTest

.

.

classElasticsearchApplicationTests{

.

.

.

.

@Autowired

.

.

privateRestHighLevelClientrestHighLevelClient;

.

.

.

.

@Test

.

.
