Elasticsearch Cloud Client Not Working

Hello!
I am trying to connect Elasticsearch using Springboot since last 3 days but no luck at all. I tried to google and find many codes on the elastic search discussion forum, but nothing worked till now. Many code of TransportClient are found but, its already deprecated now. So, tried using RestHighLevelClient.

Please suggest me code that works with Elasticsearch 7.7.

I just need a Client to talk to Elasticsearch from my Spring Boot Application.

Below is the code I am trying

    import org.apache.http.HttpHost;

    import org.apache.http.auth.AuthScope;

    import org.apache.http.auth.UsernamePasswordCredentials;

    import org.apache.http.client.CredentialsProvider;

    import org.apache.http.impl.client.BasicCredentialsProvider;

    import org.elasticsearch.client.RestClient;

    import org.elasticsearch.client.RestClientBuilder;

    import org.elasticsearch.client.RestHighLevelClient;

    import org.springframework.context.annotation.Bean;

    import org.springframework.context.annotation.Configuration;

    import org.springframework.data.elasticsearch.repository.config.EnableElasticsearchRepositories;

    @Configuration

    @EnableElasticsearchRepositories

    public class EsConfig {

    // @Value("${elasticsearch.host}")

    private String host ="https://xxxxxxxxxxxxx.us-east-1.aws.found.io";

    //@Value("${elasticsearch.port}")

    private int  port =9243;

    //@Value("${elasticsearch.username}")

    private String userName = "xxxxxxxx";

    //@Value("${elasticsearch.password}")

    private String password ="xxxxxx";

    @Bean(destroyMethod = "close")

    public RestHighLevelClient restClient() {

    final CredentialsProvider credentialsProvider = new BasicCredentialsProvider();

    credentialsProvider.setCredentials(AuthScope. ANY,

    new UsernamePasswordCredentials(userName, password));

    RestClientBuilder builder = RestClient.builder ( new HttpHost(host, port))

    .setHttpClientConfigCallback(httpClientBuilder -> httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider));

    RestHighLevelClient client = new RestHighLevelClient(builder);

    //System.out.println("============> "+client.indices());

    return client;

    }

     public static void  main(String[] args) {

    EsConfig es = new  EsConfig();

    }

    }

    But, when I start the application I get the below error:

You are using spring data elasticsearch I guess.

Make sure you are using the version 4.0 of spring data elasticsearch.

HTH.

Thank you for your quick response.

I tired to replace the data elasticsearch in maven pom.xml
For, your reference below is the pom.xml

Did everything to make it work, but I don't where and what I am doing wrong.

Thank you

When using springboot with elasticsearch, you need to be explicit with some transitive dependencies as SpringBoot declares a version 6.4...

Basically you can put this in your pom.xml:

<properties>
  <elasticsearch.version>7.7.0<elasticsearch.version>
</properties>

See documentation here: https://docs.spring.io/spring-boot/docs/current/reference/html/howto.html#howto-customize-dependency-versions

What is the output of

mvn dependency:tree

Dear Dadoonet,
Thanks a lot man, you are great!
Highly appreciate your quick and kind response.
[SOLVED] the issue.
