      <dependency><groupId>co.elastic.clients</groupId><artifactId>elasticsearch-java</artifactId><version>8.12.2</version></dependency>

如果出现版本问题，父pom.xml修改依赖声明

      <jakarta-json.version>2.0.1</jakarta-json.version><elasticsearch.version>8.12.2</elasticsearch.version><dependencyManagement><dependencies><dependency><groupId>jakarta.json</groupId><artifactId>jakarta.json-api</artifactId><version>${jakarta-json.version}</version></dependency><dependency><groupId>org.elasticsearch.client</groupId><artifactId>elasticsearch-rest-client</artifactId><version>${elasticsearch.version}</version></dependency></dependencies></dependencyManagement>
