更正应用程序的类路径，使其包含单个兼容版本的org.elasticsearch.client.RestClientBuilder。

Question

An attempt was made to call a method that does not exist. The attempt was made from the following location:

   org.hibernate.search.elasticsearch.client.impl.DefaultElasticsearchClientFactory.createClient(DefaultElasticsearchClientFactory.java:92)

The following method did not exist:

    org.elasticsearch.client.RestClientBuilder.setMaxRetryTimeoutMillis(I)Lorg/elasticsearch/client/RestClientBuilder;

The method's class, org.elasticsearch.client.RestClientBuilder, is available from the following locations:

    jar:file:/home/temp/.gradle/caches/modules-2/files-2.1/org.elasticsearch.client/elasticsearch-rest-client/7.10.2/d0c857275bcec532079cdabb7913e2611c123e70/elasticsearch-rest-client-7.10.2.jar!/org/elasticsearch/client/RestClientBuilder.class

The class hierarchy was loaded from the following locations: 
 
    org.elasticsearch.client.RestClientBuilder: 
        file:/home/temp/.gradle/caches/modules-2/files-2.1/org.elasticsearch.client/elasticsearch-rest-client/7.10.2/d0c857275bcec532079cdabb7913e2611c123e70/elasticsearch-rest-client-7.10.2.jar

Action:

Correct the classpath of your application so that it contains a single, compatible version of org.elasticsearch.client.RestClientBuilder* 

我们需要使用elasticsearch版本7.10.2，目前我们使用的是springboot版本2.3.9

有什么帮助吗？

这是application.yaml文件中弹性搜索7.10.2的正确映射吗？

 hibernate:
    format_sql: true
    search.default:
      elasticsearch:
        dynamic_mapping: true
        index_schema_management_strategy: update
        required_index_status: yellow

elasticsearch-rest-client依赖项( Elasticsearch的低级REST客户端)的版本不必与您实际使用的Elasticsearch服务器版本相匹配。elasticsearch-rest-client 7.16.3将很好地与Elasticsearch服务器7.10.2对话。如果你担心的话，elasticsearch-rest-client 7.16.3是在ASL2.0下授权的。

因此，简而言之:执行Hibernate搜索文档的建议，并升级到最新版本的elasticsearch-rest-client。请参见https://docs.jboss.org/hibernate/search/6.1/reference/en-US/html_single/#gettingstarted-framework-spring-boot-dependency-versions：

Spring在您不知情的情况下自动设置依赖项的版本。虽然这通常是一件好事，但Spring依赖关系有时会有点过时。因此，建议至少对一些关键依赖项覆盖Spring的默认值。

使用Maven，将其添加到POM中：

5.6.5.Final 7.16.3

如果你使用Elasticsearch的高级REST客户端，现在.你在泡菜里。该客户端不再是开源的，并可能导致许可问题。而且它的最后一个开源版本(7.10)可能不适用于elasticsearch-rest-client 7.16.3。因此，如果您确实需要使用高级别REST客户端的7.10或更早版本，那么您将需要使用较早版本的elasticsearch-rest-client和Hibernate搜索。
