Spring app shows NoSuchBeanDefinitionException

[Mahmudul Islam]

Hello There, I am new to this forum. It's great to be here.
Anyway. I was practicing Spring framework Annotation Configuration using XML. I have a repository, a service and a main app. There is an implementation of repository (named "customerRepository") and service (named "customerService") and the But the problem is when I ran the main app it shows "NoSuchBeanDefinitionException" exception. But I think I have done all the things right way and service and repository Autowired correctly. But it still not working. Please guide me if I am wrong at any point. I am using java 8, and app configured using maven.
Here is the error:
Exception in thread "main" org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'customerService' available
at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBeanDefinition(DefaultListableBeanFactory.java:687)

at org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:1087)
at Application.main(Application.java:16)

Here is the code:
Implemented classes>>

@Service("customerService")
public class CustomerServiceImpl implements CustomerService {
	@Autowired
	private CustomerRepository customerRepository;
	@Override
	public List<Customer> findAll() {
		return customerRepository.findAll();
	}
}

@Repository("customerRepository")
public class HibernateCustomerRepositoryImpl implements CustomerRepository {
	@Override
	public List<Customer> findAll(){
		List<Customer> customers = new ArrayList<>();		
		Customer customer = new Customer();		
		customer.setFirstName("Cris");
		customer.setLastName("Brown");		
		customers.add(customer);		
		return customers;
	}
}

public class Application {
	public static void main(String[] args) {		
		ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
		CustomerService customerService = applicationContext.getBean("customerService", CustomerService.class);		
		System.out.println(customerService.findAll().get(0).getFirstName());
	}
}
