1.spring-data-es操作ES

1.引入依赖

<!-- ES -->
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-elasticsearch</artifactId><version>2.4.2</version>
</dependency>

2.application.yml配置uris

3.SubjectInfoEs.java 创建ES实体类（指定映射和索引）

package com.sunxiansheng.subject.infra.basic.entity;import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.data.annotation.Id;
import org.springframework.data.elasticsearch.annotations.Document;
import org.springframework.data.elasticsearch.annotations.Field;
import org.springframework.data.elasticsearch.annotations.FieldType;import java.util.Date;/*** Description: 题目ES，相当于db中的表结构* @Author sun* @Create 2024/6/17 16:01* @Version 1.0*/
@Data
@AllArgsConstructor
@NoArgsConstructor
@Document(indexName = "subject_index", createIndex = false) // 指定索引名，这里的createIndex=true，默认自动创建索引
public class SubjectInfoEs {// 使用es必须的@Field(type = FieldType.Long)@Idprivate Long id;@Field(type = FieldType.Text, analyzer = "ik_smart")private String subjectName;@Field(type = FieldType.Text, analyzer = "ik_smart")private String subjectAnswer;@Field(type = FieldType.Text, analyzer = "ik_smart")private String createUser;@Field(type = FieldType.Date, index = false)private Date createTime;
}

4.SubjectEsRepository.java 依赖注入一个接口（对应于实体类）

package com.sunxiansheng.subject.infra.basic.esRepo;import com.sunxiansheng.subject.infra.basic.entity.SubjectInfoEs;
import org.springframework.data.elasticsearch.repository.ElasticsearchRepository;
import org.springframework.stereotype.Component;/*** Description:* @Author sun* @Create 2024/6/17 16:09* @Version 1.0*/
@Component
public interface SubjectEsRepository extends ElasticsearchRepository<SubjectInfoEs, Long> {}

5.SubjectEsService.java

package com.sunxiansheng.subject.infra.basic.service;/*** Description:* @Author sun* @Create 2024/6/17 16:11* @Version 1.0*/
public interface SubjectEsService {void createIndex();void getDocs();void find();void search();
}

6.SubjectEsServiceImpl.java

package com.sunxiansheng.subject.infra.basic.service.impl;import com.sunxiansheng.subject.infra.basic.entity.SubjectInfoEs;
import com.sunxiansheng.subject.infra.basic.service.SubjectEsService;
import org.springframework.data.elasticsearch.core.ElasticsearchRestTemplate;
import org.springframework.data.elasticsearch.core.IndexOperations;
import org.springframework.data.elasticsearch.core.document.Document;
import org.springframework.stereotype.Service;import javax.annotation.Resource;/*** Description:* @Author sun* @Create 2024/6/17 16:12* @Version 1.0*/
@Service
public class SubjectEsServiceImpl implements SubjectEsService {@Resourceprivate ElasticsearchRestTemplate elasticsearchRestTemplate;/*** 创建索引*/@Overridepublic void createIndex() {// 得到ES实体类中的索引信息然后创建IndexOperations indexOperations = elasticsearchRestTemplate.indexOps(SubjectInfoEs.class);// 创建索引indexOperations.create();// 绑定映射Document mapping = indexOperations.createMapping(SubjectInfoEs.class);indexOperations.putMapping(mapping);}/****/@Overridepublic void getDocs() {}@Overridepublic void find() {}@Overridepublic void search() {}
}

7.TestFeignController.java 测试

8.测试

1.请求，注意要加上loginId因为没走网关，不加就会空指针

9.添加文档

1.SubjectEsService.java

void addDocs();

2.SubjectEsServiceImpl.java

/*** 添加文档，也就相当于添加一条数据*/
@Override
public void addDocs() {List<SubjectInfoEs> list = new LinkedList<>();// 添加两条数据list.add(new SubjectInfoEs(1L, "Java", "Java", "sun", null));list.add(new SubjectInfoEs(2L, "Spring", "Spring", "sun", null));// 批量添加subjectEsRepository.saveAll(list);
}

3.TestFeignController.java

@RequestMapping("/addDocs")
public void createaddDocsIndex() {subjectEsService.addDocs();
}

4.测试

10.查找文档

1.SubjectEsService.java

void find();

2.SubjectEsServiceImpl.java

/*** 查找列对应的元素*/
@Override
public void find() {NativeSearchQuery nativeSearchQuery = new NativeSearchQueryBuilder().withQuery(QueryBuilders.matchQuery("subjectName", "Java")).build();SearchHits<SubjectInfoEs> search = elasticsearchRestTemplate.search(nativeSearchQuery, SubjectInfoEs.class);List<SearchHit<SubjectInfoEs>> searchHits = search.getSearchHits();log.info("searchHits:{}", searchHits);}

3.TestFeignController.java

@RequestMapping("/find")
public void find() {subjectEsService.find();
}

4.测试

2.自定义封装ES

1.环境准备

1.删除上面引入的ES依赖

2.删除application.yml中的ES配置

3.删除原来的文件

4.sun-club-infra 引入原生的ES依赖

<!-- 封装自定义ES -->
<dependency><groupId>org.elasticsearch</groupId><artifactId>elasticsearch</artifactId><version>7.5.2</version>
</dependency>
<dependency><groupId>org.elasticsearch.client</groupId><artifactId>elasticsearch-rest-client</artifactId><version>7.5.2</version>
</dependency>
<dependency><groupId>org.elasticsearch.client</groupId><artifactId>elasticsearch-rest-high-level-client</artifactId><version>7.5.2</version>
</dependency>
<!-- 集合工具类，配合封装自定义ES -->
<dependency><groupId>org.apache.commons</groupId><artifactId>commons-collections4</artifactId><version>4.4</version>
</dependency>

2.自定义封装集群es连接统一管理

1.目录结构

2.EsClusterConfig.java ES的集群配置的实体类

package com.sunxiansheng.subject.infra.basic.es;import lombok.Data;import java.io.Serializable;/*** Description: ES的集群配置的实体类* @Author sun* @Create 2024/6/17 17:08* @Version 1.0*/
@Data
public class EsClusterConfig implements Serializable {/*集群名称*/private String name;/*集群节点*/private String nodes;
}

3.EsConfigProperties.java 读取配置文件的es集群配置

package com.sunxiansheng.subject.infra.basic.es;import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;import java.util.ArrayList;
import java.util.List;/*** Description: 读取配置文件的集群配置* @Author sun* @Create 2024/6/17 17:10* @Version 1.0*/
@Component
@ConfigurationProperties(prefix = "es.cluster") // 这个就相当于将esConfigs对应于配置文件的es.cluster.esConfigs
public class EsConfigProperties {private List<EsClusterConfig> esConfigs = new ArrayList<>();public List<EsClusterConfig> getEsConfigs() {return esConfigs;}public void setEsConfigs(List<EsClusterConfig> esConfigs) {this.esConfigs = esConfigs;}
}

3.编写配置文件

es:cluster:es-configs[0]:name: 98bd89b5ccafnodes: ip:9200

4.EsRestClient.java Es工具类，将每个集群节点对应的某个客户端放到Map

package com.sunxiansheng.subject.infra.basic.es;import lombok.extern.slf4j.Slf4j;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;/*** Description: Es工具类* @Author sun* @Create 2024/6/17 17:43* @Version 1.0*/
@Component
@Slf4j
public class EsRestClient {/*表示某个集群节点对应的某个客户端的mapRestHighLevelClient：是由集群的ip端口数组生成的*/public static Map<String, RestHighLevelClient> clientMap = new HashMap<>();/*获取配置文件中填写的es.cluster.es-configs的集群信息*/@Resourceprivate EsConfigProperties esConfigProperties;/*** @PostConstruct：注解用于标记一个方法，该方法会在依赖注入完成后自动调用* 这里将从配置文件中读取的集群信息封装到map中*/@PostConstructpublic void initialize() {// 获取集群节点的信息List<EsClusterConfig> esConfigs = esConfigProperties.getEsConfigs();esConfigs.forEach(esClusterConfig -> {String name = esClusterConfig.getName();String nodes = esClusterConfig.getNodes();log.info("initialize.esClusterConfig.name:{},nodes:{}", name, nodes);// 将每个集群的ip端口数组转换为RestHighLevelClientRestHighLevelClient restHighLevelClient = initRestClient(esClusterConfig);if (restHighLevelClient != null) {// 如果不为空就放到clientMap中clientMap.put(name, restHighLevelClient);} else {// 如果为空，打印日志log.error("initialize.esClusterConfig.name:{},nodes:{} is null", name, nodes);}});}/*** 通过一个集群节点来初始化该集群节点对应的客户端* @param esClusterConfig* @return*/private RestHighLevelClient initRestClient(EsClusterConfig esClusterConfig) {// 得到该集群节点的IP端口数组String[] ipPortArr = esClusterConfig.getNodes().split(",");// 初始化一个HttpHost的列表List<HttpHost> httpHostList = new ArrayList<>(ipPortArr.length);// 对每一个ip端口进行处理for (String ipPort : ipPortArr) {// 分割ip端口String[] ipPortInfo = ipPort.split(":");// 校验if (ipPortInfo.length == 2) {// 创建一个HttpPost的对象，存放ip和端口HttpHost httpHost = new HttpHost(ipPortInfo[0], NumberUtils.toInt(ipPortInfo[1]));// 放到list中httpHostList.add(httpHost);}}// 创建一个HttpHost的数组，存放HttpHostHttpHost[] httpHosts = new HttpHost[httpHostList.size()];// httpHostList的数据放到这个数组里httpHostList.toArray(httpHosts);// 得到RestClientRestClientBuilder builder = RestClient.builder(httpHosts);// 升级一下RestHighLevelClient restHighLevelClient = new RestHighLevelClient(builder);return restHighLevelClient;}}

7.配置文件和依赖同上
