一、服務(wù)安裝參考
首先需要準(zhǔn)備好elasticsearch和kibana
elasticsearch的下載、安裝、使用可參考:Elasticsearch安裝
kibana的下載、安裝、使用可參考:Kibana安裝、配置
服務(wù)的啟動(dòng)使用和數(shù)據(jù)增刪改查可參考:kibana操作elasticsearch(增刪改查)
在進(jìn)行一下Java實(shí)現(xiàn)之前,先將es服務(wù)和kibana服務(wù)啟動(dòng)
二、Java實(shí)現(xiàn)新增數(shù)據(jù)到ES
Elasticsearch的服務(wù)開啟后,可以使用http請(qǐng)求進(jìn)行調(diào)用接口來操作Elasticsearch數(shù)據(jù)
請(qǐng)求的url格式如下:
http://localhost:9200/index/type/id
對(duì)于Java來說,可以使用http請(qǐng)求工具進(jìn)行實(shí)現(xiàn),同時(shí)傳參,參數(shù)為json類型數(shù)據(jù)
具體實(shí)現(xiàn)如下
1. 環(huán)境
并非要求,只是我這里使用的這個(gè)環(huán)境
JDK 1.8
Maven 3.9.4
IDEA 2023.2.1
2. 包結(jié)構(gòu)
這里主要用到三個(gè)文件:pom引入依賴,HttpClientUtils是請(qǐng)求工具,EsHttpRequestController是請(qǐng)求調(diào)用測試
3. 依賴引入
引入http工具所需要的依賴,也就是實(shí)現(xiàn)請(qǐng)求的依賴
傳入的參數(shù)為json類型所以也需要json工具的依賴
pom.xml完整內(nèi)容
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.es</groupId><artifactId>ES-HTTP</artifactId><version>1.0-SNAPSHOT</version><properties><maven.compiler.source>8</maven.compiler.source><maven.compiler.target>8</maven.compiler.target><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding></properties><dependencies><!-- https://mvnrepository.com/artifact/org.apache.httpcomponents/httpcore --><dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpcore</artifactId><version>4.4.14</version></dependency><dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpclient</artifactId><version>4.5.13</version></dependency><!--json工具--><dependency><groupId>com.alibaba.fastjson2</groupId><artifactId>fastjson2</artifactId><version>2.0.33</version></dependency></dependencies></project>
4. http請(qǐng)求工具
HttpClientUtils.java
package com.es.utils;import org.apache.http.HttpEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;/*** @ClassDescription:* @JdkVersion: 1.8* @Author: 李白* @Created: 2023/10/16 16:12*/
public class HttpClientUtils {public static void post(){}public static String doPost(String url, String str, String encoding) {String body = "";try {// 創(chuàng)建httpclient對(duì)象CloseableHttpClient client = HttpClients.createDefault();// 創(chuàng)建post方式請(qǐng)求對(duì)象HttpPost httpPost = new HttpPost(url);// 設(shè)置參數(shù)到請(qǐng)求對(duì)象中httpPost.setEntity(new StringEntity(str, encoding));// 設(shè)置header信息// 指定報(bào)文頭【Content-type】、【User-Agent】httpPost.setHeader("Content-type", "application/json;charset=UTF-8");// 執(zhí)行請(qǐng)求操作,并拿到結(jié)果(同步阻塞)CloseableHttpResponse response = client.execute(httpPost);// 獲取結(jié)果實(shí)體HttpEntity entity = response.getEntity();if (entity != null) {// 按指定編碼轉(zhuǎn)換結(jié)果實(shí)體為String類型body = EntityUtils.toString(entity, encoding);}EntityUtils.consume(entity);// 釋放鏈接response.close();return body;} catch (Exception e1) {e1.printStackTrace();return "";}}}
5. 測試代碼
編寫mian方法執(zhí)行請(qǐng)求存數(shù)據(jù)到es
EsHttoRequestController.java
package com.es.test;import com.alibaba.fastjson2.JSONObject;
import com.es.utils.HttpClientUtils;/*** @ClassDescription:* @JdkVersion: 1.8* @Author: 李白* @Created: 2023/10/16 16:12*/
public class EsHttpRequestController {public static void main(String[] args) {JSONObject js = new JSONObject();js.put("name","杜甫");js.put("age","6800");js.put("gender","男");String jsonStr = js.toJSONString();HttpClientUtils.doPost("http://127.0.0.1:9200/deviceinfo/users/1002",jsonStr,"UTF-8");}}
6. 訪問kibana服務(wù)
先看kibana服務(wù)查看數(shù)據(jù)
打開側(cè)邊欄,Analytics–Discover
查看現(xiàn)有數(shù)據(jù)
執(zhí)行5. 測試代碼
的代碼,然后刷新界面查看新增數(shù)據(jù)
如下,新增成功
