创建bean时出错 - 自动布线依赖关系注入失败

我收到此错误

这里是我的客户域

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; 
}

它已经在它的getter和setter方法

这里是我的CustomerRepository

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

下面是我的一些数据

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; 
}

这里InMemoryCustomerRepository是我的CustomerService

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

这里是我的CustomerServiceImpl

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

这里是CustomerController

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

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

发布整个堆栈跟踪。你切断了所有重要的位。 – chrylis

呦你的CustomerRepository接口应该扩展CRUDRepository之类的东西，或者注解@RepositoryDefinition，否则它不会在春天被选中。
