How to prevent @SpringBootScanApplications(scanbase="package") avoiding interfaces?

So I was running a Springboot application then I got this error

***************************  APPLICATION FAILED TO START  ***************************    Description:    A component required a bean of type 'sample.ArticledDao' that could not be found.      Action:    Consider defining a bean of type 'sample.ArticledDao' in your configuration.    

Then I checked how SpringBoot scans the files and I saw some of the files are ignored

This is how the path looks ( It's not ideal I know) :

This is the code of my Main class :

@SpringBootApplication(scanBasePackages="sample")  @EnableJpaRepositories("sample")  public class Main {          public static void main(String[] args) throws Exception {          SpringApplication.run(Main.class, args);      }  }  

This is my ArticlesDao class:

public interface ArticledDao {      List<Articles> findAll();        public void deleteArticles(Articles articles);  }  

ArticleSercviceImp class

@Component  public class ArticleSericeImp implements ArticlesServices  {      @Autowired      ArticledDao articleDao;      @Override      public List<Articles> findAll() {          return articleDao.findAll();      }        @Override      public void deleteEmployee(Articles art) {           articleDao.deleteArticles(art);      }    

ArticleRepository:

@Repository  public  class ArticlesRepository implements ArticledDao{        public ArticlesRepository(NamedParameterJdbcTemplate template) {          this.template = template;      }  NamedParameterJdbcTemplate template;        @Override      public List<Articles> findAll() {          return template.query("select * from article", new ArticlesRowMapper());      }        @Override      public void deleteArticles(Articles articles) {          final String sql = "delete from article where articleid=:articleid";          Map<String,Object> map=new HashMap<String,Object>();          map.put("articleid", articles.getId());            template.execute(sql,map,new PreparedStatementCallback<Object>() {              @Override              public Object doInPreparedStatement(PreparedStatement ps)                      throws SQLException, DataAccessException {                  return ps.executeUpdate();              }          });          }            }

I'm new to SpringBoot so I would be very grateful for your help.
