五、springboot集成elasticsearch 一、背景
前两年研究了一段时间elasticsearch当时也是网上找了很多资料最后解决个各种问题可以在springboot上运行了本来是想记录下解决过程但是由于某些原因就搁置了下来。最近手头有个项目正好需要用到elasticsearch再拿起来的时候发现很多地方都不记得了于是花了2天时间又搞了下终于可以正常运行了这次准备花点时间把遇到的一些问题、解决方法以及需要注意的地方记录下便于日后需要时查看。 二、安装docker
2.1、从官网下载docker好像需要科学上网如果不行的话就随便百度个下载吧。
2.2、安装3个Windows功能如下图 2.3、安装WSL在命令行窗口执行wsl --install如果安装不成功的话可以尝试从微软应用商店安装好像只有win10可以搜到这个搜索wsl如下图 2.4、安装docker这个没啥需要特别记录的
2.5、执行wsl --version查看当前使用的是不是wsl2如果不是wsl2并且docker也确实不能正常启动的话可以尝试切换到wsl2试试切换命令为wsl --set-default-version 2 三、下载安装elasticsearch
3.1、根据springboot版本下载对应的elasticsearch镜像对应关系如下表
Spring Data Release TrainSpring Data ElasticsearchElasticsearchSpring FrameworkSpring Boot 2023.1 (Vaughan) 5.2.x 8.11.1 6.1.x 3.2.x 2023.0 (Ullmann) 5.1.x 8.7.1 6.0.x 3.1.x 2022.0 (Turing) 5.0.x[1] 8.5.3 6.0.x 3.0.x 2021.2 (Raj) 4.4.x[1] 7.17.3 5.3.x 2.7.x 2021.1 (Q) 4.3.x[1] 7.15.2 5.3.x 2.6.x 2021.0 (Pascal) 4.2.x[1] 7.12.0 5.3.x 2.5.x 2020.0 (Ockham) 4.1.x[1] 7.9.3 5.3.2 2.4.x Neumann 4.0.x[1] 7.6.2 5.2.12 2.3.x Moore 3.2.x[1] 6.8.12 5.2.12 2.2.x Lovelace 3.1.x[1] 6.2.2 5.1.19 2.1.x Kay 3.0.x[1] 5.5.0 5.0.13 2.0.x Ingalls 2.1.x[1] 2.4.0 4.3.25 1.5.x
也可以到spring官网查看最新的对应关系
3.2、下载指定版本的elasticsearch镜像
docker pull elasticsearch:8.11.0
3.3、安装镜像
docker run --name elastic -p 9200:9200 -p 9300:9300 -e discovery.typesingle-node -d elasticsearch:8.11.0
3.4、进入镜像修改配置 3.4.1、进入容器控制台
docker exec -it elastic /bin/bash 3.4.2、进入bin目录cd bin 3.4.3、修改密码
elasticsearch-setup-passwords interactive 3.4.4、下载配置文件到本地修改
docker cp elastic:/usr/share/elasticsearch/config/elasticsearch.yml d:/ 3.4.5、在文件末尾添加不添加的话elasticsearch-head连接时会报跨域错误 http.cors.enabled: true http.cors.allow-origin: * http.cors.allow-headers: Authorization 3.4.6、上传覆盖原文件
docker cp d:\elasticsearch.yml elastic:/usr/share/elasticsearch/config/
3.5、添加IK分词插件 3.5.1、下载IK分词插件新建一个IK目录解压到目录中。 3.5.2、上传IK文件夹
docker cp d:\xxx\ik elastic:\usr\share\elasticsearch\plugins\ 3.5.3、重启elastic
docker restart elastic
3.6、JDK导入证书不是必须 3.6.1、从elasticsearch下载证书
docker cp elastic:/usr/share/elasticsearch/config/certs/http_ca.crt d:\下载目录 3.6.2、打开控制台进入JDK证书目录
cd C:\Program Files\Java\jdk-18.0.2.1\lib\security 3.6.3、执行命令导入证书
C:\Program Files\Java\jdk-18.0.2.1\binkeytool -keystore cacerts -importcert -alias es_http_ca -file d:/下载目录/http_ca.crt 四、下载安装elasticsearch-head
4.1、下载elasticsearch-head
docker pull mobz/elasticsearch-head:5
4.2、安装容器
docker run --name elastic-head -p 9100:9100 -d mobz/elasticsearch-head:5
4.3、在地址栏输入http://localhost:9100/?auth_userelasticauth_passwordxxxxx查看连接elastic是否成功注意使用https连接elasticsearchhttp://localhost:9200 五、springboot集成elasticsearch
5.1、springboot3.2.0集成elasticsearch8.11.0运行正常不过从官方文档看3.2.x要求是8.11.1。下面是必须的一些包。
?xml version1.0 encodingUTF-8?
project xmlnshttp://maven.apache.org/POM/4.0.0 xmlns:xsihttp://www.w3.org/2001/XMLSchema-instancexsi:schemaLocationhttp://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsdmodelVersion4.0.0/modelVersionparentgroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-parent/artifactIdversion3.2.0-SNAPSHOT/version/parentpropertiesjava.version17/java.version/propertiesdependenciesdependencygroupIdio.github.hakky54/groupIdartifactIdsslcontext-kickstart/artifactIdversion7.4.7/version/dependencydependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-data-elasticsearch/artifactId/dependencydependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-web/artifactId/dependency/dependencies
/project5.2、新建配置类
package com.rwzhang.elastic.elasticsearchdemo.config;import co.elastic.clients.elasticsearch.ElasticsearchClient;
import co.elastic.clients.json.jackson.JacksonJsonpMapper;
import co.elastic.clients.transport.ElasticsearchTransport;
import co.elastic.clients.transport.rest_client.RestClientTransport;
import nl.altindag.ssl.SSLFactory;
import org.apache.http.HttpHost;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.client.CredentialsProvider;
import org.apache.http.impl.client.BasicCredentialsProvider;
import org.elasticsearch.client.RestClient;
import org.elasticsearch.client.RestClientBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.elasticsearch.repository.config.EnableElasticsearchRepositories;
import org.springframework.data.repository.query.QueryLookupStrategy;Configuration
EnableElasticsearchRepositories(queryLookupStrategy QueryLookupStrategy.Key.CREATE_IF_NOT_FOUND,basePackages com.elastic.elasticsearchdemo.repository)
public class ElasticsearchConfig {Beanpublic ElasticsearchClient elasticsearchClient(){SSLFactory sslFactory SSLFactory.builder().withUnsafeTrustMaterial().withUnsafeHostnameVerifier().build();final CredentialsProvider credentialsProvider new BasicCredentialsProvider();credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(elastic, 密码));RestClientBuilder builder RestClient.builder(new HttpHost(localhost, 9200, https));builder builder.setHttpClientConfigCallback(httpClientBuilder - httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider).setSSLContext(sslFactory.getSslContext()).setSSLHostnameVerifier(sslFactory.getHostnameVerifier()));RestClient restClient builder.build();ElasticsearchTransport transport new RestClientTransport(restClient, new JacksonJsonpMapper());return new ElasticsearchClient(transport);}
}
5.3、新建实体类
public class News implements Serializable {IdField(storetrue, index false, type FieldType.Integer)Integer id;Field(analyzerik_max_word, searchAnalyzerik_smart, type FieldType.Text)String title;Field(analyzerik_max_word, searchAnalyzerik_smart, type FieldType.Text)String content;public News(String title, String content) {this.title title;this.content content;}
}
5.4、新建repository
Repository
public interface NewsRepository extends ElasticsearchRepositoryNews, Integer {Highlight(fields {HighlightField(name content)},parameters HighlightParameters(preTags {span stylecolor:red},postTags {/span},numberOfFragments 10, //片段个数fragmentSize 100 //片段长度))ListSearchHitNews findByContent(String content, Pageable pageable);long countByContent(String content);
}
5.5、新建测试类
RunWith(SpringRunner.class)
SpringBootTest
class ElasticsearchDemoApplicationTests {ResourceNewsRepository newsRepository;Testvoid countByContent() {long count newsRepository.countByContent(足球);System.out.println(StrUtil.format(countByContent: {}, count));}
}
