该问题为Springboot 自带的 es版本 和你引入的版本有冲突

查看pom文件，依次点击

 

 

 

 

 

 可以看到Springboot Es默认的版本号

 

 修改pom文件 properties 加入es版本号

    <properties>
        <java.version>1.8</java.version>
        
        <elasticsearch.version>8.6.2</elasticsearch.version>
    </properties>

es 依赖修改为

<dependency>
    <groupId>co.elastic.clients</groupId>
    <artifactId>elasticsearch-java</artifactId>
    <version>8.6.2</version>
</dependency>
