从`TransportClient`Elasticsearch 7开始不推荐使用，将在Elasticsearch 8中将其删除。（[请参阅Elasticsearch文档](https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/transport-client.html)）。`TransportClient`只要使用的Elasticsearch[版本中](https://docs.spring.io/spring-data/elasticsearch/docs/3.2.0.RELEASE/reference/html/#elasticsearch.versions)可用，Spring Data Elasticsearch将支持。
