When I try to run this code I am getting exception that I have posted. Autowired injection is not happening. What is the problem ?

Answer 1

Take a close look at the Exception, It says
nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

It looks like you are not creating sessionFactory bean. Make sure you have sessionFactory added in you spring configuration

For Example :

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"
     p:dataSource-ref="dataSource"
     p:configLocation="${hibernate.config}"
/>
