我显然在这里错过了一些东西。我正在制作一个简单的spring boot应用程序，它包含spring data jpa内陷和面部偏斜错误：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [locassa.domain.repository.PersonRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

我的代码：

应用：

@SpringBootApplication
@ComponentScan(basePackages = {"app.controller", "app.domain"})
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}

控制器：

    PersonService personService;

    @RequestMapping("/")
    public String index() {
        return "Test spring boot";
    }

    @RequestMapping("/person/{id}")
    public Person personById(@PathVariable Long id) {
        return personService.findPerson(id);
    }
}

人员服务：

public interface PersonService {

    Person findPerson(Long id);
}

PersonServiceImpl：

@Service
public class PersonServiceImpl implements PersonService {

    @Autowired
    PersonRepository personRepository;

    public Person findPerson(Long id) {
       return personRepository.findOne(id);
    }
}

PersonRepository（无法自动连线）：

public interface PersonRepository extends CrudRepository<Person, Long> {
}

已在网上搜索。我没发现一件事。有任何想法吗？
