Ошибка при создании bean-injection автоуведомленных зависимостей

Question

Я просто не могу понять это!

Я получаю эту ошибку

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'customerController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.packt.webstore.service.CustomerService com.packt.webstore.controller.CustomerController.customerService; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'customerServiceImpl': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.packt.webstore.domain.repository.CustomerRepository com.packt.webstore.service.impl.CustomerServiceImpl.customerRepository; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.packt.webstore.domain.repository.CustomerRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

Вот мой домен клиента

public class Customer { 
private String customerId; 
private String name; 
private String address; 
private int noOfOrderMade; 

public Customer(String customerId, String name){ 
    this.customerId = customerId; 
    this.name = name; 
} 

Это методы получения и установки в нем

Вот мой CustomerRepository

public interface CustomerRepository { 
List<Customer> getAllCustomers(); 
} 

Вот мой InMemoryCustomerRepository с некоторыми данными

public class InMemoryCustomerRepository implements CustomerRepository { 
private List<Customer> listOfCustomers = new ArrayList <Customer>(); 

public InMemoryCustomerRepository(){ 
    Customer c1 = new Customer("1", "Ashesh Tuladhar"); 
    c1.setAddress("Ason"); 
    c1.setNoOfOrderMade(5); 

    Customer c2 = new Customer("2", "Ismaran Duwadi"); 
    c2.setAddress("Thankot"); 
    c2.setNoOfOrderMade(10); 

    Customer c3 = new Customer("3", "Siddhartha Bhatta"); 
    c3.setAddress("Hattisar"); 
    c3.setNoOfOrderMade(15); 

    listOfCustomers.add(c1); 
    listOfCustomers.add(c2); 
    listOfCustomers.add(c3); 
} 

public List<Customer> getAllCustomers(){ 
    return listOfCustomers; 
} 

Вот мой CustomerService

public interface CustomerService { 
    List<Customer> getAllCustomers(); 
} 

Вот мой CustomerServiceImpl

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

А вот CustomerController

@Controller 
public class CustomerController { 
    @Autowired 
    private CustomerService customerService; 

    @RequestMapping("/customer") 
    public String list(Model model){ 
     model.addAttribute("customers",customerService.getAllCustomers()); 
     return "customers"; 
    } 
    } 

Answer 1

Yo Интерфейс CustomerRepository должен либо расширять что-то вроде CRUDRepository, либо иметь аннотацию @RepositoryDefinition, иначе он не будет поднят весной.
