本文主要是介绍【ElasticSearch实战】——封装java操作es基础架构，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
创建ES专栏很久了，但是写的文章非常的少，实在是项目比较忙，2018年最后一天了也该总结一下对es的封装的东西了，这篇博客我们通过java对es批量插入为主流程，来介绍一下java对接es 的全部过程；
需求处理流程：
从mysql中插入手机号7位所有的组合，然后通过程序处理补充后四位所有的可能，然后组成一个庞大的手机号码库，然后在讲手机号加密，为其他的应用提供 手机号明密文转换服务；
1、引入jar
<dependency><groupId>org.elasticsearch.client</groupId><artifactId>elasticsearch-rest-high-level-client</artifactId><version>6.0.1</version></dependency>2、根据配置创建索引
2.1、配置文件内容：
es.cluster.name=elasticsearch
es.cluster.nodes=39.**.45.**:9201 #集群ip端口都好分隔
es.client.useragent=ACS/Search 1.0
es.index.casetel={"settings":{"number_of_shards":2,"number_of_replicas":1,"max_result_window":10000000},"mappings":{"casetel":{"properties":{"telId":{"type":"long"},"tel":{"type":"keyword"},"encryptTel":{"type":"keyword"}}}}}
2.2、 配置文件对应 操作类
package com.zqf.search.es.model;import com.zqf.common.utils.JsonUtils;/*** @description* @param* @date 10:18 2018/12/9* @return* @author zhenghao
*/
public class ElasticSearchConfig {private String clusterName;private String nodes;private String userAgent;private String caseTel;public String getClusterName() {return clusterName;}public void setClusterName(String clusterName) {this.clusterName = clusterName;}public String getNodes() {return nodes;}public void setNodes(String nodes) {this.nodes = nodes;}public String getUserAgent() {return userAgent;}public void setUserAgent(String userAgent) {this.userAgent = userAgent;}public String getCaseTel() {return caseTel;}public void setCaseTel(String caseTel) {this.caseTel = caseTel;}@Overridepublic String toString() {return JsonUtils.writeValue(this);}
}
通过 spring管理配置实体类：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd"default-lazy-init="false"><bean id="esNodeConfig" class="com.zqf.search.es.model.ElasticSearchConfig"><property name="clusterName" value="${es.cluster.name}" /><property name="nodes" value="${es.cluster.nodes}" /><property name="userAgent" value="${es.client.useragent}" /><property name="caseTel" value="${es.index.casetel}" /></bean>
</beans>2.3、系统启动检查是否有索引，如果没有根据配置创建相关索引
package com.zqf.search.es.service;import java.util.Collections;
import java.util.Map;import com.sun.org.apache.bcel.internal.generic.NEW;
import com.zqf.search.es.model.ElasticSearchConfig;
import org.apache.http.HttpEntity;
import org.apache.http.HttpHost;
import org.apache.http.client.config.RequestConfig;
import org.apache.http.entity.ContentType;
import org.apache.http.entity.StringEntity;
import org.apache.http.message.BasicHeader;
import org.elasticsearch.action.ActionListener;
import org.elasticsearch.action.bulk.BulkRequest;
import org.elasticsearch.action.bulk.BulkResponse;
import org.elasticsearch.action.delete.DeleteRequest;
import org.elasticsearch.action.delete.DeleteResponse;
import org.elasticsearch.action.get.GetRequest;
import org.elasticsearch.action.get.GetResponse;
import org.elasticsearch.action.index.IndexRequest;
import org.elasticsearch.action.index.IndexResponse;
import org.elasticsearch.action.main.MainResponse;
import org.elasticsearch.action.search.*;
import org.elasticsearch.action.update.UpdateRequest;
import org.elasticsearch.action.update.UpdateResponse;
import org.elasticsearch.client.*;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationListener;
import org.springframework.context.event.ContextRefreshedEvent;
import org.springframework.stereotype.Service;/*** @description* @param* @date 10:18 2018/12/9* @return* @author zhenghao
*/
@Service
public class ElasticSearchService implements ApplicationListener<ContextRefreshedEvent> {private final Logger log = LoggerFactory.getLogger(ElasticSearchService.class);public static final int CONNECT_TIMEOUT_MILLIS = 60 * 1000;public static final int SOCKET_TIMEOUT_MILLIS = 5 * 60 * 1000;public static final int MAX_RETRY_TIMEOUT_MILLIS = SOCKET_TIMEOUT_MILLIS;public static这篇关于【ElasticSearch实战】——封装java操作es基础架构的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
