Spring failed to bean with name 'customerController'

I'm new to Spring and Spring Data and I have created simple app. However, my app's controller keep failing to autowire the repository even though I have one

CustomerController.java

package controllers;

import persistence.domains.Customer;
import repositories.CustomerService;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping(value = "/customers")
@Service
public class CustomerController {


    private CustomerService customerRepository;


    @Autowired
    public CustomerController(CustomerService customerRepository) {
        this.customerRepository = customerRepository;
    }

    @RequestMapping(method = RequestMethod.GET)
    public List<Customer> getAllCustomers() {
        return customerRepository.findAll();
    }


}

CustomerRepository.java

package persistence.repositories;

import persistence.domains.Customer;

import java.util.List;

import org.springframework.data.repository.CrudRepository;

public interface CustomerRepository extends CrudRepository<Customer,Long> {

    public Customer save(Customer customer);
    public Customer findOneByName(String name);
    public List<Customer> findAll();
}

CustomerService.java

package persistence.repositories;

import persistence.domains.Customer;

import java.util.List;

public interface CustomerService {
    /**
     * Return all customers
     * @return A list of all customers
     */
    public List<Customer> findAll();
}

RepositoryCustomerService.java

package persistence.repositories;

import persistence.domains.Customer;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Component;
import org.springframework.transaction.annotation.Transactional;

@Component
public class RepositoryCustomerService implements CustomerService {
    @Resource
    private CustomerRepository repo;

    @Transactional
    public List<Customer> findAll() {
        return repo.findAll();

    }

}
