Ao tentar dar o @Autowired no UsuárioDAO, o console me responde dessa forma. Li algumas coisas no forúm, mas não consegui resolver. Alguém poderia me ajudar?

GRAVE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'securityConfiguration': Unsatisfied dependency expressed through field 'usuarioDao'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'br.com.casadocodigo.loja.daos.UsuarioDAO' available: expected at least 1 bean which qualifies as autowire candidate.
