MyBastisConfiguration설정시

@Autowired DataSource dataSource;

@Bean

public SqlSessionFactory sqlSessionFactory(DataSource dataSource, ApplicationContext applicationContext) throws Exception{

이렇게 선언하는건랑 

@Bean

public SqlSessionFactory sqlSessionFactory(@Autowired DataSource dataSource, ApplicationContext applicationContext) throws Exception{

강의에서처럼 메소드안에 직접 @Autowired 를 선언하면서 인자로 넣는거랑 차이가 있나요?
