Error creating bean, Bean instantiation via factory method failed - spring-boot

Question

am trying to configure elasticsearch in Spring boot but Bean instantiation is failing, Node Builder has been removed from elasticsearch api so am trying to use Settings.Builder but its not helping
below is the code:
import java.io.File;
import java.io.IOException;
import java.net.InetAddress;
import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.common.settings.Settings;
import org.elasticsearch.common.transport.InetSocketTransportAddress;
import org.elasticsearch.transport.client.PreBuiltTransportClient;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.elasticsearch.core.ElasticsearchOperations;
import org.springframework.data.elasticsearch.core.ElasticsearchTemplate;
import org.springframework.data.elasticsearch.repository.config.EnableElasticsearchRepositories;
#Configuration
#EnableElasticsearchRepositories(basePackages = "com.demo.elastic.elasticdemo.repository")
public class ElasticConfiguration {
#SuppressWarnings("resource")
#Bean
public ElasticsearchOperations elasticsearchTemplate() throws IOException {
File tempDir = File.createTempFile("temp-elastic", Long.toString(System.nanoTime()));
System.out.println("Temp directory: "+ tempDir.getAbsolutePath());
Settings.Builder settings = Settings.builder()
//http settings
.put("http.enable", "true")
.put("http.cor.enable", "true")
.put("http.cors.allow-origin", "https?:?/?/localhost(:[0-9]+)?/")
.put("http.port", "9200")
//transport settings
.put("transport.tcp.port", "9300")
.put("network.host", "localhost")
//node settings
.put("node.data", "true")
.put("node.master", "true")
//configuring index
.put("index.number_of_shards", "1")
.put("index.number_of_replicas", "2")
.put("index.refresh_interval", "10s")
.put("index.max_results_window", "100")
//configuring paths
.put("path.logs", new File (tempDir, "logs").getAbsolutePath())
.put("path.data", new File (tempDir, "data").getAbsolutePath())
.put("path.home", tempDir);
//.build();
TransportClient client = new PreBuiltTransportClient(Settings.EMPTY)
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"),9300));
return new ElasticsearchTemplate(client);
}
}
what am i doing wrong.??
error am getting:
