自动装配存储库时的org.springframework.beans.factory.BeanCreationException

Question

我想通过CrudRepository实现在Controller中进行一些数据库查询，但是我从unknow原因得到了org.springframework.beans.factory.BeanCreationException。我没有使用Repository对象执行任何操作，因此我只在控制器中发布声明部分

控制器类;

@Controller
public class Controller {

    @Autowired
    PersonRepository repo;
    ...

PersonRepository类

@Repository
public interface PersonRepository extends CrudRepository<Person, Long> {

}

调度-servlet.xml中

当然，存储库位于wymysl.database包中。
