Question

当尝试使用从2.1.8到2.3.4的Spring Boot更新应用程序时，我设法解决了一些错误并成功构建，但是尝试运行主应用程序后，以下错误消息已被终止我

***************************
APPLICATION FAILED TO START
***************************

Description:

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 org.elasticsearch.client.RestClientBuilder, is available from the following locations:

    jar:file:/Users/pei/.m2/repository/org/elasticsearch/client/elasticsearch-rest-client/7.6.2/elasticsearch-rest-client-7.6.2.jar!/org/elasticsearch/client/RestClientBuilder.class

    org.elasticsearch.client.RestClientBuilder: file:/Users/pei/.m2/repository/org/elasticsearch/client/elasticsearch-rest-client/7.6.2/elasticsearch-rest-client-7.6.2.jar


Action:

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

我做了很多研究，包括this SO question和很多与我相似的案例，但是我发现它们最终是不同的。例如，在我的情况下，似乎只有一个位置提供method class ...，而./mvnw dependency:tree -Pwar | grep elasticsearch的结果给出

[INFO] +- org.hibernate:hibernate-search-elasticsearch:jar:5.11.2.Final:compile
[INFO] |  +- org.elasticsearch.client:elasticsearch-rest-client:jar:7.6.2:compile
[INFO] |  +- org.elasticsearch.client:elasticsearch-rest-client-sniffer:jar:5.6.8:compile
[INFO] +- org.elasticsearch.plugin:analysis-icu:jar:5.0.0-alpha5:test
[INFO] +- org.elasticsearch.plugin:analysis-kuromoji:jar:5.0.0-alpha5:test

我假设elasticsearch-rest-client和elasticsearch-rest-client-sniffer是两个不同的依赖项，所以就好像它们没有冲突吗？

编辑：

我添加了@gowridev注释中建议的以下依赖项

<dependency>
    <groupId>org.hibernate.search</groupId>
    <artifactId>hibernate-search-backend-elasticsearch</artifactId>
    <version>6.0.0.Beta3</version>
</dependency>

错误仍然存在，但会稍微改变

Answer 1

事实证明我误解了错误消息。

Correct the classpath of your application so that it contains a single, compatible version of org.hibernate.search.engine.Version

搜索此消息时，其他人大多遇到在不同地方重复依赖的问题。那使我认为我的是同样的原因。不是。

关键不是该版本不是单个，而是它不是兼容。

简单

org.hibernate.search.elasticsearch.client.impl.DefaultElasticsearchClientFactory.createClient()

此方法正在调用

org.elasticsearch.client.RestClientBuilder.setMaxRetryTimeoutMillis()

但是如错误消息所指出，它不存在。

不存在它不是因为它在那里，但是计算机无法找到它。它只是不在那里。 elasticsearch 7.6.2没有这种方法；自elasticsearch 7起已将其删除。

作为解决方案，我将elasticsearch降级为6.8.13，现在一切正常。只需将其添加到pom.xml/<properties>

<elasticsearch.version>6.8.13</elasticsearch.version>

如果有更好/更合适的解决方案，请告诉我。

试图调用一个不存在的方法...纠正类路径
