      public static boolean isMatchingBean(@NonNull org.springframework.beans.factory.BeanFactory beanFactory, @NonNull String beanName, @Nullable Class<?> beanType)
      Determines whether a given bean registered in the Spring BeanFactory matches by name and type.
      Parameters:
      beanFactory - Spring BeanFactory used to resolve the bean; must not be null.
      beanName - name of the bean.
      beanType - type of the bean.
      Returns:
