     uris: https://192.168.1.110:30920
     username: elastic
     password: 123456

依赖文件

子pom.xml引入elasticsearch-java依赖

      <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>
