2021年11月28日 穀粒商城學習——P125 springboot 整合es

@官網文檔

1，創建gulimall-search，導入es的高階依賴 等mvn依賴

    <properties>
        <java.version>1.8</java.version>
        <!--默認org.elasticsearch是6.4.3版本，不匹配，如下圖-->
        <elasticsearch.version>7.4.2</elasticsearch.version>
    </properties>

        <dependency>
            <groupId>org.elasticsearch.client</groupId>
            <artifactId>elasticsearch-rest-high-level-client</artifactId>
            <version>7.4.2</version>
        </dependency>

 

 2，編寫es自定義配置

package com.atguigu.gulimall.search.config;

import org.apache.http.HttpHost;
import org.elasticsearch.client.RestClient;
import org.elasticsearch.client.RestHighLevelClient;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * 1、導入依賴
 * 2、編寫配置，給容器中注入一個RestHighLevelClient
 * 3、參照API https://www.elastic.co/guide/en/elasticsearch/client/java-rest/7.4/index.html
 */
@Configuration
public class GulimallElasticSearchConfig {
    @Bean
    public RestHighLevelClient esRestClient(){
        RestHighLevelClient client = new RestHighLevelClient(
                RestClient.builder(
                        new HttpHost("192.168.56.10", 9200, "http")));
        return client;
    }
}

 

3, 編寫測試

package com.atguigu.gulimall.search;

import org.elasticsearch.client.RestHighLevelClient;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import javax.annotation.Resource;

@RunWith(SpringRunner.class)
@SpringBootTest
public class GulimallSearchApplicationTests {
    @Resource private RestHighLevelClient client;
    @Test
    public void contextLoads() {
        System.out.println(client);
    }
}
