Elasticsearch SpringBoot 整合 ES 测试保存

一、修改Config

官方文档：https://www.elastic.co/guide/en/elasticsearch/client/java-rest/7.4/java-rest-low-usage-requests.html#java-rest-low-usage-request-options

package com.mangoubiubiu.search.config;

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


@Configuration
public class SearchConfig {

    /**
     * 通用设置项 基于默认规则加的设置
     */
    public static final RequestOptions COMMON_OPTIONS;
    static {
        RequestOptions.Builder builder = RequestOptions.DEFAULT.toBuilder();
//        builder.addHeader("Authorization", "Bearer " + TOKEN);
//        builder.setHttpAsyncResponseConsumerFactory(
//                new HttpAsyncResponseConsumerFactory
//                        .HeapBufferedResponseConsumerFactory(30 * 1024 * 1024 * 1024));
        COMMON_OPTIONS = builder.build();
    }

    @Bean
    public RestHighLevelClient esRestClient(){
        RestHighLevelClient client = new RestHighLevelClient(
                RestClient.builder(
                        new HttpHost("192.168.56.10", 9200, "http")));

        return client;
    }

}

二、Junit 测试保存

官方文档：https://www.elastic.co/guide/en/elasticsearch/client/java-rest/7.4/java-rest-high-document-index.html

package com.atguigu.gulimall.search;

import com.alibaba.fastjson.JSON;
import com.atguigu.gulimall.search.config.SearchConfig;
import lombok.Data;
import org.elasticsearch.action.index.IndexRequest;
import org.elasticsearch.action.index.IndexResponse;
import org.elasticsearch.client.RestHighLevelClient;
import org.elasticsearch.common.xcontent.XContentType;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import java.io.IOException;


@RunWith(SpringRunner.class)
@SpringBootTest
public class GulimallSearchApplicationTests {

    @Autowired
    private RestHighLevelClient restHighLevelClient;

    @Test
   public void contextLoads() {
        System.out.println(restHighLevelClient);
    }

    /**
     * 测试存储数据到ES
     * 保存更新
     */
    @Test
    public void indexData() throws IOException {
        IndexRequest request = new IndexRequest("users");
        request.id("1"); //数据id
//        request.source("userName","zhangsan","age",18,"gender","男");
        User user = new User();
        user.setUserName("张三");
        user.setAge(18);
        user.setGender("男");
        String jsonString = JSON.toJSONString(user);
        request.source(jsonString, XContentType.JSON); //要保存的内容

        //执行保存操作
        IndexResponse index = restHighLevelClient.index(request, SearchConfig.COMMON_OPTIONS);

        //提前有用的响应的数据

        System.out.println(index);
    }

    @Data
    class User{
        private String userName;
        private String gender;
        private Integer age;


    }


}

有数据，保存成功
