Elasticsearch 7.17 Java Client Api

Elasticsearch官方建议使用新版的Java Api Client替代原有的Rest客户端，这篇文章会简单讲解

新版api的使用。

The Elasticsearch Java API Client is an entirely new client library that has no relation to the older High Level Rest Client (HLRC). This was a deliberate choice to provide a library that is independent from the Elasticsearch server code and that provides a very consistent and easier to use API for all Elasticsearch features.

首先引入依赖
