I have following queries.
Is it necessary to give "filter" tag in web.xml, if yes than why?
In my application, I have two application context(one for spring security and other for dispatcher-servlet), is it possible for springSecurityConfig.xml to access bean definition which is defined in dispatcher-servlet.xml?
what is the flow of spring-security configuration.Upto my knowledge, i have understood that intercept-url tag intercept the request and check appropriate role using expression language.I am not able to understand how it looks appropriate role in DB via authentication-manager i've provided.
below is my userService bean definition in service.xml
<bean name="userService" class="com.qait.cdl.services.impl.UserServiceImpl">
<property name="userDao" ref="userDao" />
</bean>
below is userService interface
public interface UserService extends UserDetailsService{
}
this UserDetailsService is from springframework
below is UserServiceimpl class
public class UserServiceImpl implements UserService {
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException, DataAccessException {
UserDetails userDetails = null;
if(username != null && !"".equals(username)){
User user = userDao.get(username);
if(user != null){
UserGroupAuthority groupAuthority = userDao.getUserAuthority(user);
if(groupAuthority != null){
Collection<GrantedAuthority> grantedAuthorities = getGrantedAuthorities(groupAuthority.getAuthority());
userDetails = new org.springframework.security.core.userdetails.User(user.getUsername(), user.getPassword(),
true, true, true, true, grantedAuthorities);
}
}
}
return userDetails;
}
#Override
public Collection<GrantedAuthority> getGrantedAuthorities(String authority) {
List<GrantedAuthority> grantedAuthorities = new LinkedList<GrantedAuthority>();
grantedAuthorities.add(new GrantedAuthorityImpl("ROLE_USER"));
return grantedAuthorities;
}
#Override
public UserGroupAuthority getUserAuthority(User user) {
return userDao.getUserAuthority(user);
}
}
Simply the problem is , it is not validating the given intercept-url. Where I am doing mistake?

Activate springSecurityFilterChain in your web.xml. It's an entry point of Spring Security. If springSecurityFilterChain is deactivated then Spring Security will never work.
