一、es的jdbc类

-package com.yunshi.index.dao.esdb;import org.apache.log4j.Logger;import org.elasticsearch.client.transport.TransportClient;import org.elasticsearch.common.settings.Settings;import org.elasticsearch.common.transport.InetSocketTransportAddress;import org.elasticsearch.transport.client.PreBuiltTransportClient;import java.net.InetAddress;/** * es连接数据库相关类 * Created by mk on 2017/11/22. */public class ElasticSearchJdbc {    private static final Logger logger = Logger.getLogger("ElasticSearchJdbc");    private  String cluster_name = null;// 实例名称    private  String cluster_serverip = null;// elasticSearch服务器ip    private  String indexname = null;// 索引名称    private TransportClient client = null;    public  String getCluster_name() {return cluster_name;}    public  void setCluster_name(String cluster_name) {this.cluster_name = cluster_name;}    public  String getCluster_serverip() {return cluster_serverip;}    public  void setCluster_serverip(String cluster_serverip) {this.cluster_serverip = cluster_serverip;}    public  String getIndexname() {return indexname;}    public  void setIndexname(String indexname) {this.indexname = indexname;}    private void init() {        // 设置集群名称        Settings settings = Settings.builder().put("cluster.name", cluster_name).build();        // 创建client        client = new PreBuiltTransportClient(settings);        if (this.cluster_name == null || "".equals(this.cluster_name)) {            throw new EsdbException("ES未配置实例名称！");        }        if (this.cluster_serverip == null || "".equals(this.cluster_serverip)) {            throw new EsdbException("ES未配置服务器IP！");        }        if (this.indexname == null || "".equals(this.indexname)) {            throw new EsdbException("ES未配置索引名称！");        }        try {            // 增加地址和端口            client.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName(cluster_serverip), 9300));        }catch (Exception e){            logger.error("class : ElasticSearchJdbc --> method : getClient 创建ES客户端连接异常！");            e.printStackTrace();        }    }    /**     * 返回一个ElasticSearch的连接客户端     *     * @return client     */    public TransportClient getClient() {        if(client==null) {            init();        }        return client;    }}-

二、spring.xml配置

-<!--初始化ES配置并启动--><bean id="ElasticSearchJdbc" class="com.yunshi.index.dao.esdb.ElasticSearchJdbc" init-method="init"><property name="cluster_name" value="${cluster_name}"/><property name="indexname" value="${indexname}"/><property name="cluster_serverip" value="${cluster_serverip}"/></bean>-

三、es配置文件

-cluster_name=zhonghuayuntestcluster_serverip=192.168.0.248indexname=onair_resource-

四、总结

虽然此博客内容简单，但是进行这样的抽取工作还是很有必要的！
