Spring + Boot + Cloud + JDK8 + Elasticsearch 单节点模式下实现全文检索高亮-分页显示快速入门案例

1. 安装elasticsearch+ik分词器插件

sudo wget https://release.infinilabs.com/analysis-ik/stable/elasticsearch-analysis-ik-8.13.4.zip
sudo mkdir -p ./es_plugins/analysis-ik
sudo mkdir ./es_data
sudo unzip elasticsearch-analysis-ik-8.13.4.zip -d ./es_plugins/analysis-ik
sudo chown liber:liber es_data/ es_plugins/

1.1 docker-compose

version: '3.8'
services:elasticsearch:image: docker.elastic.co/elasticsearch/elasticsearch:8.13.4container_name: elasticsearchenvironment:- discovery.type=single-node- xpack.security.enabled=true - bootstrap.memory_lock=true- "ES_JAVA_OPTS=-Xms512m -Xmx512m"ulimits:memlock:soft: -1hard: -1mem_limit: 1g  ports:- "9200:9200"- "9300:9300"networks:- esnetvolumes:- ./es_data:/usr/share/elasticsearch/data- ./es_plugins:/usr/share/elasticsearch/plugins
networks:esnet:

启动容器命令：

docker-compose up -d

1.2 修改密码

进入容器：

docker exec -it elasticsearch bash

验证分词器的安装：

bin/elasticsearch-plugin list

手动更改密码：使用 Elasticsearch 提供的 elasticsearch-reset-password 工具重置 elastic 用户的密码：

bin/elasticsearch-reset-password -u elastic

1.3 可能会用到的指令

删除索引：

curl -u elastic:dxOHCIBIWu+2djY6qtF1 -X DELETE "http://127.0.0.1:9200/articles"

测试ik分词器：

 curl -X GET "http://127.0.0.1:9200/_analyze" -u elastic:dxOHCIBIWu+2djY6qtF1 -H 'Content-Type: application/json' -d'{"analyzer": "ik_max_word","text": "Spring Boot 使用入门"}'

说明：dxOHCIBIWu+2djY6qtF1是密码。

3. 数据库操作

create database if not exists blog;
use blog;
CREATE TABLE if not exists users

说明：Eurka中心，Redis在本案例暂时没有演示，需要Eurka中心是为了注册到服务中心通过Gateway网关进行转发，读者可以自行去掉一些不必要的依赖项还有配置项。

6. ElasticsearchConfig.java

import org.springframework.context.annotation.Configuration;@Configuration
public class ElasticsearchConfig {@Value("${elasticsearch.url}")private String url;@Value("${elasticsearch.username}")private String username;@Value("${elasticsearch.password}")private String password;@Value("${elasticsearch.port}")private int port;@Beanpublic ElasticsearchClient elasticsearchClient() {// 配置 Jackson 的 ObjectMapper 并注册 JavaTimeModuleObjectMapper objectMapper = new ObjectMapper();objectMapper.registerModule(new JavaTimeModule());// 创建自定义的 JacksonJsonpMapperJacksonJsonpMapper jsonpMapper = new JacksonJsonpMapper(objectMapper);// 配置身份验证final BasicCredentialsProvider credentialsProvider = new BasicCredentialsProvider();credentialsProvider.setCredentials(AuthScope.ANY,new UsernamePasswordCredentials(username, password));// 配置 RestClientRestClientBuilder builder = RestClient.builder(new HttpHost(url, port)).setHttpClientConfigCallback(httpClientBuilder -> httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider));RestClient restClient = builder.build();// 使用 RestClientTransport 创建 ElasticsearchClientRestClientTransport transport = new RestClientTransport(restClient, jsonpMapper);return new ElasticsearchClient(transport);}
