  <p>Can anyone help me understand this. why this <strong>BeanCreationNotAllowedException</strong> ?</p>
  <p><strong>UPDATE 1</strong></p>
  <p>I added the class and created the spring.factories file. But I am not able to start the application.  I am getting the following error.</p>
  <pre><code>***************************
  APPLICATION FAILED TO START
  ***************************
  
  Description:
  
  Parameter 0 of method metricsWebMvcConfigurer in org.springframework.boot.actuate.autoconfigure.metrics.web.servlet.WebMvcMetricsAutoConfiguration required a single bean, but 2 were found:
      - prometheusMeterRegistry: defined by method 'prometheusMeterRegistry' in class path resource [org/springframework/boot/actuate/autoconfigure/metrics/export/prometheus/PrometheusMetricsExportAutoConfiguration.class]
      - consoleLoggingRegistry: defined by method 'consoleLoggingRegistry' in class path resource [io/github/jhipster/config/metric/JHipsterLoggingMetricsExportConfiguration.class]
  
  
  Action:
  
  Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed.
  </code></pre>
  <p>Which bean i should use and how to make it qualified for autowiring?</p>
