Version mismatch in between Elasticsearch Client and Cluster: 7.9.3 - 7.8.0

启动程序的时候报了Version mismatch in between Elasticsearch Client and Cluster: 7.9.3 - 7.8.0的警告
好像查询不成功，请问怎么在依赖中将版本呢将客户端版本降低呢

去改你的pom中继承spring boot的parent 节点的版本

这个可以查看你的集群版本是否与依赖版本是否对应 不对应可以重新以下依赖

        <dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-elasticsearch</artifactId>
            <version>${spring-elasticsearch.version}</version>
        </dependency>
        <dependency>
            <groupId>org.elasticsearch.client</groupId>
            <artifactId>elasticsearch-rest-high-level-client</artifactId>
            <version>${elasticsearch.version}</version>
