How do we consume REST api with Http basic authentication in spring?

HelloRequestDTO helloRequestDTO=new helloRequestDTO();//should have data
RestTemplate restTemplate = new RestTemplate();

String URL="https://api.test.code";	
StringBuilder buildURIPath = new StringBuilder(URL);
buildURIPath.append("/"+"veify");
buildURIPath.append("/"+transact);
							
logger.info("Request with {} " , buildURIPath);

URI uri = URI.create(buildURIPath.toString());

logger.info("Request URI: {} ",uri);
logger.info("Request Body: {} ",helloRequestDTO);    
	    
HttpHeaders headers = new HttpHeaders();
headers.setBasicAuth(username, password); //Basic Auth
logger.info("U and P: {} , {}",username,password); //username, password


HttpEntity<HelloRequestDTO> httpEntityRequest = new HttpEntity<HelloRequestDTO>(helloRequestDTO,headers);

logger.info("Request entity: {} ",httpEntityRequest);			    

ResponseEntity<HelloResponseDTO> helloResponseDtoEntity = restTemplate.exchange(uri, HttpMethod.POST,httpEntityRequest, HelloResponseDTO.class);

HelloResponseDTO helloResponseDTO = helloResponseDtoEntity.getBody();

logger.info("helloResponseDTO Body: {} ",helloResponseDTO);

logger.info("helloResponse Entity: {} ",helloResponseDtoEntity);					

if(helloResponseDtoEntity.getStatusCode().equals(HttpStatus.CREATED)) {
	
	logger.info("Verify Response Created {} " , HttpStatus.CREATED);
	
	saveResponse(request,status,helloResponseDtoEntity.toString());
	response.setResCode("00");
	response.setResMsg("Success");						
}
else
{
	logger.info("Verify Response Status failed {} " ,helloResponseDtoEntity.getStatusCode());
	status=helloResponseDtoEntity.getStatusCode().toString();
	saveResponse(request,status,helloResponseDtoEntity.toString());
}
