工程依赖：

1）SpringBoot 2.1.10

2）elasticsearch-rest-high-level-client 7.9.3

查看maven依赖发现实际引入依赖：

org.elasticsearch:elasticsearch:6.4.3
org.elasticsearch.client:elasticsearch-rest-client:6.4.3

排查：

1）进入spring-boot-starter-parent依赖

2）进入spring-boot-dependencies

3) 搜索elastic 发现SpringBoot默认的elasticsearch版本是6.4.3

解决：pom文件指定elasticsearch版本，搞定
