谷粒商城学习——P125 springboot 整合es

@官网文档

1，创建gulimall-search，导入es的高阶依赖 等mvn依赖

    <properties>
        <java.version>1.8java.version>
        
        <elasticsearch.version>7.4.2elasticsearch.version>
    properties>

        <dependency>
            <groupId>org.elasticsearch.clientgroupId>
            <artifactId>elasticsearch-rest-high-level-clientartifactId>
            <version>7.4.2version>
        dependency>

 2，编写es自定义配置

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、导入依赖
 * 2、编写配置，给容器中注入一个RestHighLevelClient
 * 3、参照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, 编写测试

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);
    }
}
