Unable to implement SpringSecurity-Hibernate simplest example - security

Question

I was going through following post Spring login form example and many other post of Spring Security to create a login example but I was not able to prepare any simple example.
I was trying to incorporate solution from this post Spring login form example
but problem is that I want Hibernate session factory to be injected in the UserDAO so that I can write query to get userName from table. #Autowire is not working
so I used
<context:annotation-config />
<context:component-scan
base-package="com.tcs.ceg" />
but now i am getting runtime exception as cannot autowire sessionFactory as no matching bean found.
But a bean with this name I have created in my applicationContext.xml .
Can anyone tell me how can I inject sessionFactory?
my application-security.xml:

#Override
public User getUser(String username) throws DbComparisonException {
String password = "rajesh";
boolean enabled = true;
boolean accountNonExpired = true;
boolean credentialsNonExpired = true;
boolean accountNonLocked = true;
Collection<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
authorities.add(new GrantedAuthorityImpl("admin"));
User user = new User(username, password, enabled,
accountNonExpired, credentialsNonExpired, accountNonLocked, authorities);
return user;
}
}
Please note i havent written following line in UserDaoimpl because sessionFactory is null
sessionFactory.getCurrentSession().createQuery("from User").list();//throws null pointer exception

Answer 1

I think that the sessionFactory attribute of your DAO must be of type LocalSessionFactoryBean.
EDIT :
In your applicationContext.xml file, you have declared this bean :
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource1" />
<property name="configLocation">
<value>classpath:hibernate.cfg.xml</value>
</property>
<property name="configurationClass">
<value>org.hibernate.cfg.AnnotationConfiguration</value>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="current_session_context_class">thread</prop>
<prop key="cache.provider_class">org.hibernate.cache.NoCacheProvider</prop>
</props>
</property>
</bean>
which is a org.springframework.orm.hibernate3.LocalSessionFactoryBean.
Then, in your DAO, sessionFactory is a org.hibernate.SessionFactory.
So I think that Spring is unable to autowire your bean in the DAO since it is not the same type.
