Answer 1

I think you are doing several things multiple times:

This:

<context:annotation-config/>

already includes this:

<!-- Turn on @Autowired, @PostConstruct etc support -->
<bean class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor" />
<bean class="org.springframework.context.annotation.CommonAnnotationBeanPostProcessor" />

Remove the <bean> definitions and try again, perhaps that’s the reason.

Reference: Annotation-based container configuration

Update: about your new error:

HibernateDaoSupport needs either a HibernateTemplate or a SessionFactory as dependency. You have a SessionFactory, but Spring can’t wire it because by default, Spring doesn’t autowire properties, so you need to either manually wire the property or set <beans default-autowire="byType"> (if you use byName, you will have to change your SessionFactory bean definition to id="sessionFactory")
