Spring Boot 2.1的Elasticsearch版本

Question

在我的Spring Boot （ 2.0.5 ）项目中，我正在使用Elasticsearch （ 5.6.9 ）。 但是，由于测试环境中的一些错误，我们将转向Spring boot（ 2.1.0 ）。 当我运行该应用程序时，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.

    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

以前的pom.xml文件运行良好：

有人可以说出哪个版本的elasticsearch与Spring Boot 2.1.0兼容吗？ 我通读过时的类似问题。 Spring Boot，elasticsearch和spring数据elasticsearch的兼容版本

Answer 1

您可以转到Spring Boot项目 Github存储库并检查任何依赖版本：

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

Answer 2

不知道它是否仍然是实际的，但是您需要尝试的第一件事是添加核心Elasticsearch库，因为REST客户端依赖它。

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