How you configure correctly elasticsearch 7.1.1 with spring boot 2.15?

Question

I am using Elasticsearch 7.1.1 with spring-boot 2.1.5. I downloaded Elasticsearch and run it. When I start the spring project I am getting an error. The is "failed to load Elasticsearch nodes : org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are available: [{#transport#-1}{rsi4dYt_RuOBGCdwUH3Cgg}{127.0.0.1}{127.0.0.1:9200}]". How can I runt it correctly

I used these configurations.

spring.elasticsearch.jest.multi-threaded=true
spring.main.allow-bean-definition-overriding=true
spring.data.elasticsearch.cluster-nodes=localhost:9200
spring.data.elasticsearch.repositories.enabled=true
spring.elasticsearch.jest.uris=http://localhost:9200
spring.elasticsearch.jest.connection-timeout=3s
spring.elasticsearch.rest.uris=http://localhost:9200
spring.data.elasticsearch.cluster-name=elasticsearch

and

@Configuration
@EnableElasticsearchRepositories(basePackages = 
"com.example.elasticsearch.repository")
public class ElasticSearchConfiguration {
 @Bean
 public Client client() throws UnknownHostException {
    Settings settings = Settings.builder()
            .put("client.transport.sniff", true)
            .put("cluster.name", "elasticsearch").build();
    @SuppressWarnings("resource")
    TransportClient client = new PreBuiltTransportClient(settings)
            .addTransportAddress(new 
 TransportAddress(InetAddress.getByName("127.0.0.1"), 9200));

    return client;
}

@Bean
public ElasticsearchOperations elasticsearchTemplate() throws 
UnknownHostException {
    return new ElasticsearchTemplate(client());
   }
}

I think were you are getting it wrong is using port = 9200 try to use port = 9300. From connecting to Elastic Search server from your application the port number 9300 is used and not 9200.
