Use ElasticSearch client in non web application with Spring - spring

Question

I'm creating a non web application with Spring that will read data from Kafka and write it in ElasticSearch, i included the following dependency:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-elasticsearch</artifactId>
</dependency>
And the following configuration class:
#Configuration
public class ElasticSearchConfig extends AbstractElasticsearchConfiguration{
#Bean
public RestHighLevelClient elasticsearchClient() {
final ClientConfiguration clientConfiguration = ClientConfiguration.builder().connectedTo("localhost:9200")
.build();
return RestClients.create(clientConfiguration).rest();
}
}
When i execute the following code:
#Override
public void run(String... args) throws Exception {
IndexRequest request = new IndexRequest("test-transactions");
request.id("2");
request.source("{\"name\":\"Sammie\"," + "\"lastname\":\"Goldner\"," + "\"username\":\"hugh.vonrueden\","
+ "\"amount\":9622235.2009}", XContentType.JSON);
client.index(request, RequestOptions.DEFAULT);
}
I get the following exception:
Caused by: java.lang.ClassNotFoundException: org.springframework.http.HttpHeaders
at java.net.URLClassLoader.findClass(URLClassLoader.java:382) ~[na:1.8.0_251]

at java.lang.ClassLoader.loadClass(ClassLoader.java:351) ~[na:1.8.0_251]
... 46 common frames omitted
If i include the following dependency the code works fine:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
But it brings a lot of other functionalities that i don't want in my code, is there any other way to configure spring-boot-starter-data-elasticsearch in a non web application?
Thanks.
