带有 RestHighLevelClient 的 Elasticsearch Spring 数据

Question

I don't understand the relationship between the High Level REST CLient (which replaces the Transport Client) and Spring Data Elasticsearch.

There are tutorials ( https://www.baeldung.com/spring-data-elasticsearch-tutorial ) showing how to make JPA-style queries with auto-implemented methods like getSomethingById(). They utilize this interface:

public interface ElasticsearchRepository<T, ID extends Serializable> extends ElasticsearchCrudRepository<T, ID> {

But ElasticsearchRepository seems to require a @Configuration -Class with an ElasticsearchTemplate-Bean and that requires the TransportClient. As far as I have tried out, there is no way of replacing it with the High/Low Level Java Rest Clients, no?

So if I want to use the newest official Client, there is no JPA-goodness for me?

Answer 1

在Spring Data ES回购中有一个关于这个问题的公开问题： https ： //jira.spring.io/browse/DATAES-407

Answer 2

spring-data-elasticsearch 3.2.0, now available as M2 contains the code to use the RestClient.

See my answer to this question: What Elasticsearch client does Spring-Data-Elasticsearch use under the hood? for how to set it up

Answer 3

Spring Data Moore has been release including this feature (October 8 2019).This is the main description:

Elasticsearch: High Level REST Client support & non Jackson based entity mapping

If yo need more detail You will be able to have a look to this jira issue:
