Spring Boot 2.1的Elasticsearch版本

Question

In my Spring Boot ( 2.0.5 ) project I was using Elasticsearch ( 5.6.9 ). However, due to some bugs in testing environment we are moving to Spring boot( 2.1.0 ). When I run the application the following message comes up:

***************************
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

Can someone tell which version of elasticsearch is compatible with Spring Boot 2.1.0? I read through similar questions which were outdated. Compatible versions of Spring boot,elasticsearch and spring data elasticsearch

Answer 1

You can go to Spring Boot project Github repository and check any dependency version:

• In Spring Boot 2.0.x Elasticsearch version is defined as 5.6.16 ( link )
• In Spring Boot 2.1.x Elasticsearch version is defined as 6.4.3 ( link )

Answer 2

Not sure if it's still actual, but the first thing you need to try is to add core Elasticsearch library, because REST client depends on it.

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