springboot2如何集成ElasticSearch6.4.3

作者:琴瑟裹腹

这篇文章主要介绍了springboot2如何集成ElasticSearch6.4.3问题,具有很好的参考价值,希望对大家有所帮助。如有错误或未考虑完全的地方,望不吝赐教

springboot2集成ElasticSearch6.4.3

es的服务器部署过程不再赘述,网上资源很多。

(1)pom文件

<dependency>
			<groupId>org.elasticsearch</groupId>
			<artifactId>elasticsearch</artifactId>
			<version>6.4.3</version>
		</dependency>
		<!-- https://mvnrepository.com/artifact/org.elasticsearch.client/transport -->
		<dependency>
			<groupId>org.elasticsearch.client</groupId>
			<artifactId>transport</artifactId>
			<version>6.4.3</version>
			<exclusions>
				<exclusion>
					<groupId>org.elasticsearch</groupId>
					<artifactId>elasticsearch</artifactId>
				</exclusion>
			</exclusions>
		</dependency>

(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<Map<String, Object>> 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<Map<String, Object>> 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

import org.elasticsearch.search.SearchHit;
import org.elasticsearch.search.SearchHits;
import org.elasticsearch.search.aggregations.AggregationBuilders;
import org.elasticsearch.search.aggregations.metrics.max.Max;
