springboot2集成ElasticSearch6.4.3
springboot版本：2.0.0
ES版本：6.4.3
es的服务器部署过程不再赘述，网上资源很多。
（1）pom文件
org.elasticsearch
elasticsearch
6.4.3
org.elasticsearch.client
transport
6.4.3
org.elasticsearch
elasticsearch
（2）yml文件
spring:
data:
elasticsearch:
cluster-name: es
ip: 10.10.77.142
port : 9300
pool : 1
logPath : 1 # 选择日志存入的方式，1 将日志存入ElasticSearch；2存入数据库
（3）创建ElasticsearchConfig类，进行ES的初始化连接
import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.common.settings.Settings;
import org.elasticsearch.common.transport.TransportAddress;
import org.elasticsearch.transport.client.PreBuiltTransportClient;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import java.net.InetAddress;
/**
* Created by dell on 2019/5/30.
*/
@Configuration
public class ElasticsearchConfig {
private static final Logger LOGGER = LoggerFactory.getLogger(ElasticsearchConfig.class);
/**
* elk集群地址
*/
@Value("${spring.data.elasticsearch.ip}")
private String hostName;
/**
* 端口
*/
@Value("${spring.data.elasticsearch.port}")
private String port;
/**
* 集群名称
*/
@Value("${spring.data.elasticsearch.cluster-name}")
private String clusterName;
/**
* 连接池
*/
@Value("${spring.data.elasticsearch.pool}")
private String poolSize;
/**
* Bean name default 函数名字
*
* @return
*/
@Bean(name = "transportClient")
public TransportClient transportClient() {
LOGGER.info("Elasticsearch初始化开始。。。。。");
TransportClient transportClient = null;
try {
// 配置信息
Settings esSetting = Settings.builder()
.put("cluster.name", clusterName) //集群名字
.put("client.transport.sniff", true)//增加嗅探机制，找到ES集群
.put("thread_pool.search.size", Integer.parseInt(poolSize))//增加线程池个数，暂时设为5
.build();
//配置信息Settings自定义
transportClient = new PreBuiltTransportClient(esSetting);
TransportAddress transportAddress = new TransportAddress(InetAddress.getByName(hostName), Integer.valueOf(port));
transportClient.addTransportAddresses(transportAddress);
} catch (Exception e) {
LOGGER.error("elasticsearch TransportClient create error!!", e);
}
return transportClient;
}
}
（4）创建ES分页工具
import java.util.List;
import java.util.Map;
/**
* Created by dell on 2019/5/30.
*/
public class EsPage {
/**
* 当前页
*/
private int currentPage;
/**
* 每页显示多少条
*/
private int pageSize;
/**
* 总记录数
*/
private int recordCount;
/**
* 本页的数据列表
*/
private List> recordList;
/**
* 总页数
*/
private int pageCount;
/**
* 页码列表的开始索引（包含）
*/
private int beginPageIndex;
/**
* 页码列表的结束索引（包含）
*/
private int endPageIndex;
/**
* 只接受前4个必要的属性，会自动的计算出其他3个属性的值
*
* @param currentPage
* @param pageSize
* @param recordCount
* @param recordList
*/
public EsPage(int currentPage, int pageSize, int recordCount, List> recordList) {
this.currentPage = currentPage;
this.pageSize = pageSize;
this.recordCount = recordCount;
this.recordList = recordList;
// 计算总页码
pageCount = (recordCount + pageSize - 1) / pageSize;
// 计算 beginPageIndex 和 endPageIndex
// >> 总页数不多于10页，则全部显示
if (pageCount <= 10) {
beginPageIndex = 1;
endPageIndex = pageCount;
}
// 总页数多于10页，则显示当前页附近的共10个页码
else {
// 当前页附近的共10个页码（前4个 + 当前页 + 后5个）
beginPageIndex = currentPage - 4;
endPageIndex = currentPage + 5;
// 当前面的页码不足4个时，则显示前10个页码
if (beginPageIndex < 1) {
beginPageIndex = 1;
endPageIndex = 10;
}
// 当后面的页码不足5个时，则显示后10个页码
if (endPageIndex > pageCount) {
endPageIndex = pageCount;
beginPageIndex = pageCount - 10 + 1;
}
}
}
}
（5）创建ES工具类ElasticsearchUtil
