[SPRING] 봄 : 누락 된 JPA 메타 모델

봄 : 누락 된 JPA 메타 모델

JPA 리파지토리를 사용하는 간단한 스프링 MVC 프로젝트에서 무엇이 잘못 될지 이해할 수 없습니다. 힌트를 주시겠습니까?

도메인:

package com.test.app;

@Entity
@Table(name = "foo_table")
public class FooDomain {

    @Id
    @Column(name = "id", unique = true, nullable = false)
    private Integer id;

    @Column(name = "text", nullable = false)
    private String text;

    // getters & setters here...

}

저장소

package com.test.app;

@RepositoryDefinition(domainClass=FooDomain.class, idClass=Long.class)
public interface FooRepository extends CrudRepository<FooDomain, Long> {}

제어 장치

@Controller
public class HomeController {

    @Autowired
    private FooRepository fooRepository;

    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String home(Locale locale, Model model) {
        model.addAttribute("rowsNumber", fooRepository.count());
        return "home";
    }

}
