org.springframework.beans.factory.UnsatisfiedDependencyException: Ошибка создания компонента с именем studentService

Question

Я запускаю приложение Java Spring без использования Spring Boot и получаю следующую ошибку.

SEVERE: StandardWrapper.Throwable
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'studentService': Unsatisfied dependency expressed through field 'studentRepository'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'studentsystem2.ikubinfo.repository.StudentRepository' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

Это мой rest-servlet.xml

РЕДАКТИРОВАТЬ StudentRepository.java

package studentsystem2.ikubinfo.repository;

import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;

import studentsystem2.ikubinfo.entity.Student;

@Repository
public interface StudentRepository extends CrudRepository<Student, Long> {

}

Я думаю, что базовый пакет не найден для сканирования компонентов, но я не понимаю, почему. Что не так с настройками?
