Unable to connect to Elasticsearch server 6.2.2 from spring application

Elastic Stack Elasticsearch
1

Hello everyone,

I am struggling to connect my webapp based on Spring Framework 4.3.13 (not a springboot app) to an Elasticsearch server 6.2.2.

I've googling al lot but with no result unfortunally.
Here the code I'm executing:

Maven Dependencies:

    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-elasticsearch</artifactId>
        <version>4.0.0.RELEASE</version>
    </dependency>

    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-commons</artifactId>
        <version>2.1.10.RELEASE</version>
    </dependency>

    <!-- https://mvnrepository.com/artifact/org.elasticsearch/elasticsearch -->
    <dependency>
        <groupId>org.elasticsearch</groupId>
        <artifactId>elasticsearch</artifactId>
        <version>6.2.2</version>
    </dependency>

    <dependency>
        <groupId>org.elasticsearch.client</groupId>
        <artifactId>elasticsearch-rest-high-level-client</artifactId>
        <version>6.2.2</version>
    </dependency>
    <dependency>
        <groupId>org.elasticsearch.client</groupId>
        <artifactId>elasticsearch-rest-client</artifactId>
        <version>6.2.2</version>
    </dependency>

The configuration Class:

@Configuration
@EnableElasticsearchRepositories(queryLookupStrategy = QueryLookupStrategy.Key.CREATE_IF_NOT_FOUND,
		basePackages = "com.myapp.repositories")
public class ElasticsearchConfig {
	@Bean
	RestHighLevelClient elasticsearchClient() {
		RestHighLevelClient client = new RestHighLevelClient(RestClient.builder(
				new HttpHost("localhost", 9200, "http")
		));
		return client;
	}
	@Bean
	ElasticsearchRestTemplate elasticsearchTemplate() {
		return new ElasticsearchRestTemplate(elasticsearchClient());
	}
}

The error stack:

Look at the Spring Data Elasticsearch documentation: https://docs.spring.io/spring-data/elasticsearch/docs/current/reference/html/#preface.metadata

You should probably use here Spring Data Elasticsearch 3.1.x or upgrade all which could be even better.
