Amazon OpenSerach - Elastic Search service integration with Spring application (Java, Maven))

I have taken Amazon OpenSerach - Elastic Search service to integrate with our Spring application (Java, Maven)) we are facing issue integrating it as there is no proper documentation on it. I have tried multiple ways to Integrate it. Sometimes there is some build [OSS] issue and if I fix that there is a content issue I need some help.

import io.searchbox.client.JestClientFactory;
import io.searchbox.client.config.HttpClientConfig;

@Configuration
public class ElasticsearchConfig {

    @Value("${elastic.uri}")
    private String elasticHost;
    @Bean
    public RestClient getRestClient() {
        RestClient restClient = RestClient.builder(
                new HttpHost(elasticHost, 9200)).build();
        return restClient;
    }

    @Bean
    public RestHighLevelClient client() {
        ClientConfiguration clientConfiguration
                = ClientConfiguration.builder()
                .connectedTo(elasticHost)
                .build();

        return RestClients.create(clientConfiguration).rest();
    }

    @Bean
    public ElasticsearchOperations elasticsearchTemplate() {
        return new ElasticsearchRestTemplate(client());
    }
    @Bean
    public JestClient jest(){
        JestClientFactory factory = new JestClientFactory();
        factory.setHttpClientConfig(new HttpClientConfig
                .Builder("http://"+elasticHost+":9200")
                .multiThreaded(true)
                //Per default this implementation will create no more than 2 concurrent connections per given route
                // and no more 20 connections in total
                        .build());
        return factory.getObject();
    }

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
        </dependency>

using this dependency gives OSS error and if I specify the version of the Elastic in dependency then it is Content type is missing error
