ElasticsearchClient使用详解
一、maven依赖
org.springframework.boot spring-boot-starter-web 2.7.10 co.elastic.clients elasticsearch-java 8.12.0 org.elasticsearch.client elasticsearch-rest-client 8.12.0 com.fasterxml.jackson.core jackson-databind 2.15.0 二、连接配置
注意：代码中的es相关信息需要修改为实际的es信息
import co.elastic.clients.elasticsearch.ElasticsearchClient;import co.elastic.clients.json.jackson.JacksonJsonpMapper;import co.elastic.clients.transport.rest_client.RestClientTransport;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;@Configurationpublic class ElasticsearchConfig { @Bean public ElasticsearchClient elasticsearchClient() { // 1. 创建基础认证凭证 final CredentialsProvider credentialsProvider = new BasicCredentialsProvider(); credentialsProvider.setCredentials( AuthScope.ANY, new UsernamePasswordCredentials(\"您的用户名\", \"您的密码\") ); // 2. 配置RestClientBuilder RestClientBuilder builder = RestClient.builder( new HttpHost(\"es集群ip1\", 9200), new HttpHost(\"es集群ip2\", 9200)) .setDefaultHeaders(new Header[]{ // 添加必要的请求头 new BasicHeader(\"Content-Type\", \"application/json\"), new BasicHeader(\"Accept\", \"application/json\") }) .setHttpClientConfigCallback(httpClientBuilder -> { httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider) .addInterceptorLast((HttpResponseInterceptor) (response, context) ->response.addHeader(\"X-Elastic-Product\", \"Elasticsearch\"));// 这部分为了避免旧版本报错（如果es更新到了8.xx，把这个去掉即可） return httpClientBuilder; }) .setRequestConfigCallback(requestConfigBuilder -> requestConfigBuilder.setConnectTimeout(5000) // 连接超时5秒 .setSocketTimeout(60000) // 套接字超时60秒 ); // 配置全局 ObjectMapper，用于序列化/反序列化，如：user_name->userName ObjectMapper mapper = new ObjectMapper().setPropertyNamingStrategy(PropertyNamingStrategies.SNAKE_CASE); return new ElasticsearchClient(new RestClientTransport(builder.build(), new JacksonJsonpMapper(mapper))); }}三、普通分页查询
注意：代码中的es索引需要修改为实际的es索引
import co.elastic.clients.elasticsearch.ElasticsearchClient;import co.elastic.clients.elasticsearch._types.query_dsl.BoolQuery;import co.elastic.clients.elasticsearch._types.query_dsl.Query;import co.elastic.clients.elasticsearch._types.query_dsl.QueryBuilders;import co.elastic.clients.elasticsearch.core.ScrollResponse;import co.elastic.clients.elasticsearch.core.SearchRequest;import co.elastic.clients.elasticsearch.core.SearchResponse;import lombok.extern.slf4j.Slf4j;import org.apache.commons.collections.CollectionUtils;import org.apache.commons.lang3.StringUtils;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import service.ElasticsearchQueryService;import service.bo.UserInfoBO;import java.io.IOException;import java.util.ArrayList;import java.util.List;import java.util.stream.Collectors;@Service(\"elasticsearchQueryService\")@Slf4jpublic class ElasticsearchQueryServiceImpl implements ElasticsearchQueryService { @Autowired private ElasticsearchClient client; /** * 查询ES数据 * @param userInfoBO 查询条件 * @return 匹配的文档列表 */ public List queryUserInfoByES(UserInfoBO userInfoBO) throws IOException { // 构建查询条件 BoolQuery.Builder boolQuery = QueryBuilders.bool(); if (StringUtils.isNotBlank(userInfoBO.getUserName())) { boolQuery.must(Query.of(q -> q .term(t -> t .field(\"user_name\") .value(userInfoBO.getUserName()) ) )); } SearchRequest searchRequest = new SearchRequest.Builder() .index(\"t_user_info\") .query(boolQuery.build()._toQuery()) .from(0) .size(10) .build(); log.info(\"Elasticsearch query request: {}\", searchRequest.toString()); // 2、分页查询 SearchResponse response = client.search( searchRequest, UserInfoBO.class ); // 处理查询结果 return response.hits().hits().stream() .map(hit -> hit.source()) .collect(Collectors.toList()); }}四、游标查询（Scroll Query）
由于es分页查询的total值最大只会返回10000，所以，当查询的数据量大于10000条数据时，需要使用游标查询的方式来进行查询。
import co.elastic.clients.elasticsearch.ElasticsearchClient;import co.elastic.clients.elasticsearch._types.query_dsl.BoolQuery;import co.elastic.clients.elasticsearch._types.query_dsl.Query;import co.elastic.clients.elasticsearch._types.query_dsl.QueryBuilders;import co.elastic.clients.elasticsearch.core.ScrollResponse;import co.elastic.clients.elasticsearch.core.SearchRequest;import co.elastic.clients.elasticsearch.core.SearchResponse;import lombok.extern.slf4j.Slf4j;import org.apache.commons.collections.CollectionUtils;import org.apache.commons.lang3.StringUtils;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import service.ElasticsearchQueryService;import service.bo.UserInfoBO;import java.io.IOException;import java.util.ArrayList;import java.util.List;import java.util.stream.Collectors;@Service(\"elasticsearchQueryService\")@Slf4jpublic class ElasticsearchQueryServiceImpl implements ElasticsearchQueryService { @Autowired private ElasticsearchClient client; /** * 使用游标查询ES数据（适合大数据量分页） * @param userInfoBO 查询条件 * @return 匹配的文档列表 */ public List scrollSearch(UserInfoBO userInfoBO) throws IOException { List result = new ArrayList(); // 1、构建查询条件 BoolQuery.Builder boolQuery = QueryBuilders.bool(); if (userInfoBO.getStatus() != null) { boolQuery.must(Query.of(q -> q .term(t -> t .field(\"status\") .value(userInfoBO.getStatus()) ) )); } SearchRequest searchRequest = new SearchRequest.Builder() .index(\"t_user_info\") .query(boolQuery.build()._toQuery()) .size(5) .scroll(t -> t.time(\"1m\")) .build(); log.info(\"Elasticsearch query request: {}\", searchRequest.toString()); // 2、初始化游标查询 SearchResponse searchResponse = client.search( searchRequest, UserInfoBO.class ); List temp = searchResponse.hits().hits().stream() .map(hit -> hit.source()) .collect(Collectors.toList()); result.addAll(temp); final String scrollId = searchResponse.scrollId(); try { // 3、循环获取后续批次 while (CollectionUtils.isNotEmpty(temp)) { ScrollResponse scrollResponse = client.scroll(s -> s .scrollId(scrollId) .scroll(t -> t.time(\"1m\")), UserInfoBO.class ); temp = scrollResponse.hits().hits().stream() .map(hit -> hit.source()) .collect(Collectors.toList()); result.addAll(temp); } } finally { // 3. 清理游标 if (scrollId != null) { client.clearScroll(c -> c.scrollId(scrollId)); } } return result; }}五、过程中的问题及解决方法

解决方法：配置全局命名策略，在”连接配置“中，增加一下配置：
// 配置全局 ObjectMapper，用于序列化/反序列化时处理驼峰命名问题，如：user_name->userName ObjectMapper mapper = new ObjectMapper().setPropertyNamingStrategy(PropertyNamingStrategies.SNAKE_CASE); return new ElasticsearchClient(new RestClientTransport(builder.build(), new JacksonJsonpMapper(mapper)));问题三：Jackson时间格式处理问题（Caused by: com.fasterxml.jackson.databind.exc.InvalidFormatException: Cannot deserialize value of type `java.util.Date` from String \"2025-04-30 00:00:00\": not a valid representation (error: Failed to parse Date value \'2025-04-30 00:00:00\': Cannot parse date \"2025-04-30 00:00:00\": while it seems to fit format \'yyyy-MM-dd\'T\'HH:mm:ss.SSSX\', parsing fails (leniency? null))）

frames omitted分析：这个异常是jackson在处理json字符串 to Object类型的时候，json字符串中包含类似\"yyyy-MM-dd HH:mm:ss\"或\"yyyy-MM-dd HH:mm\"格式的时间字符串，这种格式是属于国内常用时间格式，jackson默认是不认识的。当你的字符串中一旦出现这种，jackson会直接给你报错。
解决方案：在对应的属性上添加注解@JsonFormat注解，指明时间格式，如：
@JsonFormat(pattern = \"yyyy-MM-dd HH:mm:ss\")private Date createTime;
