Почему возникает ошибка Error creating bean with name 'studentRepository' defined in StudentRepository defined in @EnableJpaRepositories?

Question

[abozhov]

Переделываю под hibernate, до этого на jdbc работало, сейчас решил, убрать dao, и добавить это. При запуске ошибка:
Error starting ApplicationContext. To display the condition evaluation report re-run your application with 'debug' enabled.

[Сергей Горностаев]

abozhov, не это. Аннотации на классе StudentsTableApplication покажите.

[abozhov]

Сергей Горностаев,

@SpringBootApplication
@EnableJpaRepositories
public class StudentsTableApplication implements CommandLineRunner {
    private Logger logger = LoggerFactory.getLogger(this.getClass());
    public static void main(String[] args) {
        SpringApplication.run(StudentsTableApplication.class, args);
    }
    @Autowired
    private StudentRepository studentRepository;
    @Override
    public void run(String... args) throws Exception {

    }
}

[сергей кузьмин]

@SpringBootApplication
@EnableJpaRepositories
@EntityScan("ru.bozhov.studentstable.models")
public class StudentsTableApplication {
    public static void main(String[] args) {
        SpringApplication.run(StudentsTableApplication.class, args);
    }

}
