一、项目说明
- 利用HBase存储海量数据，解决海量数据存储和实时更新查询的问题；
- 利用ElasticSearch作为HBase索引，加快大数据集中实时查询数据；
- 使用到的大数据组件有：Hadoop-2.7.3、HBase-1.3.1、zookeeper-3.4.5、ElasticSearch-7.8.0
- 实验环境：
虚拟机（操作系统CentOS7.6） + 个人PC（Windows）+ Eclipse或者Idea - 大数据环境：3节点构成的
全分布式环境 - 项目系统架构图如下：
- 本项目是利用hbase和elasticsearch的API来完成数据的写入和检索
二、环境搭建
- 创建3台虚拟机，即3节点，主节点内存4G、从节点内存3G，可根据自己电脑配置来设置；
- 安装部署Hadoop全分布式，可参考：Hadoop2.7.3全分布式环境搭建
- 安装部署zookeeper全分布式，可参考：Zookeeper的集群安装
- 安装部署HBase全分布式，可参考：HBase几种安装方式，
注意：需要先安装zookeeper并启动后，再安装和启动hbase - 安装部署ElasticSearch集群，可参考：Linux下安装ElasticSearch集群，
注意：需要使用es普通用户启动集群，安装成功后各个节点上启动
三、编写程序

load2DB.insert(); } public static void main(String[] args) throws Exception { start(); } } -
编写Query查询类，代码如下：
package com.bigdata.query; import com.alibaba.fastjson.JSONObject; import com.bigdata.utils.ConstantUtil; import com.bigdata.utils.ElasticSearchUtil; import com.bigdata.utils.HBaseUtil; import org.apache.hadoop.hbase.Cell; import org.apache.hadoop.hbase.CellUtil; import org.apache.hadoop.hbase.client.Result; import org.apache.hadoop.hbase.util.Bytes; import java.io.IOException; import java.util.List; import java.util.Map; /** * * 搜索逻辑是先搜索ElasticSearch，再查HBase */ public class Query { private HBaseUtil hBaseUtil = new HBaseUtil(); private ElasticSearchUtil elasticSearchUtil = new ElasticSearchUtil(); private JSONObject result = new JSONObject(); private JSONObject tmpJS = new JSONObject(); public String query(String target) { result.clear(); tmpJS.clear(); long startTime = System.currentTimeMillis(); List<Map<String, Object>> listMap = elasticSearchUtil.queryStringQuery(target); long endTime = System.currentTimeMillis(); float seconds = (endTime - startTime) / 1000F; ConstantUtil.LOG.info("ElasticSearch查询耗时" + Float.toString(seconds) + " seconds."); for (Map<String, Object> m : listMap) { String id = m.get("id").toString(); JSONObject tmpJS = new JSONObject(); tmpJS.put("id", id); Result res = null; try { long s1 = System.currentTimeMillis(); res = hBaseUtil.get(ConstantUtil.TABLE_NAME, id); long e1 = System.currentTimeMillis(); float se1 = (e1 - s1) / 1000F; ConstantUtil.LOG.info("HBase查询耗时" + Float.toString(se1) + " seconds."); Cell[] cells = res.rawCells(); for (Cell cell : cells) { String col = Bytes.toString(CellUtil.cloneQualifier(cell)); System.out.println(col); String value = Bytes.toString(CellUtil.cloneValue(cell)); System.out.println(value); tmpJS.put(col, value); } result.put(id, tmpJS); } catch (IOException e) { e.printStackTrace(); result.put(id, "查询失败!"); } } return result.toString(); } public static void main(String[] args) throws Exception { Query query = new Query(); long startTime = System.currentTimeMillis(); System.out.println(query.query("100004")); long endTime = System.currentTimeMillis(); float seconds = (endTime - startTime) / 1000F; ConstantUtil.LOG.info(" 耗时" + Float.toString(seconds) + " seconds."); } } -
编写ManagerQuery查询类，代码如下：
package com.bigdata.manager; import org.springframework.stereotype.Component; import com.bigdata.query.Query; @Component public class ManagerQuery { private static Query query = new Query(); public static String getQueryResult(String target) { try { String result = query.query(target); System.out.println(result); return result; } catch (Exception e) { e.printStackTrace(); return "查询出现异常，请通知研发人员!"; } } public static void main(String[] args) { String target = "牧之桃"; String result = ManagerQuery.getQueryResult(target); System.out.println(result); } } -
编写SearchService服务类（可参考SpringMVC代码写作），代码如下：
package com.bigdata.service; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.context.annotation.ComponentScan; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import com.bigdata.manager.ManagerQuery; @RestController @EnableAutoConfiguration @ComponentScan(basePackages = {"com.bigdata"}) public class SearchService { @RequestMapping("/search") public String search(String target) { try { return ManagerQuery.getQueryResult(target); } catch (Exception e) { e.printStackTrace(); } return "不小心出错了!"; } // 主方法，像一般的Java类一般去右击run as application时候，执行该方法 public static void main(String[] args) throws Exception { SpringApplication.run(SearchService.class, args); } } -
编写SearchController控制类（可参考SpringMVC代码写作），代码如下：
package com.bigdata.controller; import org.springframework.boot.SpringApplication; import org.springframework.stereotype.Controller; import org.springframework.ui.ModelMap; import org.springframework.web.bind.annotation.RequestMapping; /** * 注解声明，该类为Controller类 并自动加载所需要的其它类 */ @Controller public class SearchController { @RequestMapping("/index") String testdo(ModelMap map) { //这里返回HTML页面 return "index_search"; } // 主方法，像一般的Java类一般去右击run as application时候，执行该方法 public static void main(String[] args) { SpringApplication.run(SearchController.class, args); } } -
编写ApplicationBootSystem启动类，代码如下：
package com.bigdata.boot; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.context.annotation.ComponentScan; /** * 根启动类 */ @SpringBootApplication @ComponentScan(basePackages = "com.bigdata") public class ApplicationBootSystem { public static void main(String[] args) { SpringApplication.run(ApplicationBootSystem.class, args); } } -
新建static，并在其下新建plugins，并将bootstrap-3.3.7和bootstrap-table包复制到该目录下
-
新建template目录，并在其下面新建index_search.html文件：
具体代码如下：<!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1"> <!-- The above 3 meta tags *must* come first in the head;

写完成后，项目结构如下所示：
四、测试流程
-
先执行HBaseUtil工具类main方法，完成HBase测试表和目标表的创建，验证程序和hbase的连通性；
-
再执行ElasticSearch工具类main方法，完成ElasticSearch测试表和目标表的创建，验证程序和ElasticSearch的连通性；
-
再执行LoadDataToHBaseAndES类，完成数据写入HBase和ElasticSearch中；
-
再执行ApplicationBootSystem启动类，启动springboot入口程序；
-
最后打开浏览器输入：http://localhost:8084/bigdata/index，在打开的界面中的搜索框输入查询关键字，如输入3，点击【搜一下】按钮，正常情况下会看到如下结果：

尝试输入不同的条件，查看到不同的结果，
注意：需要观察检索的实时性或者速度是很快的。另外，还可以尝试下修改测试数据集，使得其数据量变得更大些，然后再查看其检索速度，读者可以自行尝试。文章来源地址https://www.toymoban.com/news/detail-626967.html
