【问题描述】：

在我的 Spring Boot(2.0.5) 项目中，我使用的是 Elasticsearch(5.6.9) .但是，由于测试环境中的一些错误，我们正在迁移到 Spring boot(2.1.0)。当我运行应用程序时，出现以下消息：

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

Description:

An attempt was made to call the method org.elasticsearch.action.admin.indices.mapping.put.PutMappingRequestBuilder.execute()Lorg/elasticsearch/action/ActionFuture; but it does not exist. Its class, org.elasticsearch.action.admin.indices.mapping.put.PutMappingRequestBuilder, is available from the following locations:

    jar:file:/C:/Users/User/.m2/repository/org/elasticsearch/elasticsearch/5.6.9/elasticsearch-5.6.9.jar!/org/elasticsearch/action/admin/indices/mapping/put/PutMappingRequestBuilder.class

It was loaded from the following location:

    file:/C:/Users/User/.m2/repository/org/elasticsearch/elasticsearch/5.6.9/elasticsearch-5.6.9.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of org.elasticsearch.action.admin.indices.mapping.put.PutMappingRequestBuilder

当前 pom.xml 文件

以前的 pom.xml 文件运行良好：

谁能告诉 Spring Boot 2.1.0 哪个版本的 elasticsearch 兼容？我通读了类似的过时问题。 Compatible versions of Spring boot,elasticsearch and spring data elasticsearch

【解决方案1】：

你可以去Spring Boot project Github 仓库查看依赖版本：

在 Spring Boot 2.0.x 中 Elasticsearch 版本定义为 5.6.16 (link)
在 Spring Boot 2.1.x 中 Elasticsearch 版本定义为 6.4.3 (link)

【解决方案2】：

不确定它是否仍然是实际的，但您需要尝试的第一件事是添加核心 Elasticsearch 库，因为 REST 客户端依赖于它。

<dependency>
    <groupId>org.elasticsearch</groupId>
    <artifactId>elasticsearch</artifactId>
    <version>6.7.0</version>
</dependency>
