Autowire doesn't work on servlets - spring

Question

I can't figure out why Autowired of DAOs classes works fine in Test classes but not in servlets. web.xml file load correctly context configuration as i can see by the log, so the problem must be in my applicationContext file.
This is my servlet:
#Controller
public class TestAutowired extends HttpServlet {
private static final long serialVersionUID = 1L;
#Autowired
private IUserDao uDao;
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
uDao.getUserById(1);
}
}
And this is my ApplicationContext (configuration.xml):
<?xml version="1.0" encoding="UTF-8"?>
<!-- Spring configuration -->
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</bean>

<property name="entityManagerFactory" ref="dbEntityManagerFactory" />
</bean>
<bean class = "org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor" />
</beans>
any hint?

The servlet lifecycle is managed by the container, not Spring.
