Bootstrap

JAVA中Elasticsearch使用

jar导入

代码示例:

	   <!-- 阿里JSON解析器 -->
       <dependency>
           <groupId>com.alibaba</groupId>
           <artifactId>fastjson</artifactId>
           <version>1.2.78</version>
       </dependency>

       <!--ES-->
       <dependency>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
       </dependency>

配置文件

配置示例:

#ES配置
#ES连接地址
spring.elasticsearch.uris=ip:9200
#ES账号
spring.elasticsearch.username=username
#ES密码
spring.elasticsearch.password=password
spring.elasticsearch.connection-timeout=30s

ES工具类编写

代码示例:

package com.xxx;【修改引用地址】

import com.alibaba.fastjson.JSON;
import org.elasticsearch.action.delete.DeleteRequest;
import org.elasticsearch.action.delete.DeleteResponse;
import org.elasticsearch.action.index.IndexRequest;
import org.elasticsearch.action.index.IndexResponse;
import org.elasticsearch.action.support.WriteRequest;
import org.elasticsearch.action.update.UpdateRequest;
import org.elasticsearch.action.update.UpdateResponse;
import org.elasticsearch.client.RequestOptions;
import org.elasticsearch.client.RestHighLevelClient;
import org.elasticsearch.common.xcontent.XContentType;
import org.elasticsearch.core.TimeValue;
import org.elasticsearch.rest.RestStatus;
import org.springframework.stereotype.Service;

import java.io.IOException;

    public EsUtils(RestHighLevelClient esClient) {
   
        this.esClient = esClient;
    }

    /**

     */
    public boolean index(String index, String id, Object object) {
   
        try {
   
            //创建ES客户端
            IndexRequest indexRequest = new IndexRequest(index)
                    .id(id)
                    .source(JSON.toJSONString(object), XContentType.JSON);
            //使用IMMEDIATE刷新策略【请求向ElasticSearch提交了数据,立即进行数据刷新,然后再结束请求】
            indexRequest.setRefreshPolicy(WriteRequest.RefreshPolicy.IMMEDIATE);
            //新增ES数据
            IndexResponse response
