How to use custom userDetails in Spring Security

[khobab]

Hi,

I am authentication using custom UserDetailsService and its working fine. My question is, in

publice UserDetails loadUserByUsername

function I am returning org.springframework.security.core.userdetails.User . Now I want to have my custom class that will implement UserDetails Interface and I want to return Instance of that class from function loadUserByUsername.

Reason for this is I want to add extra information in the spring security session. And this is the only possible solution I could think of.

Please tell me how can I do it. Or if there is anything else that i should do to add extra information to session like userId

After hours of searching and experimenting I was able to do it like this.

Make a new service say MyUserService that will implement org.springframework.security.core.userdetails.User DetailsService and has annotation @Service. UserDetailsService only has one method loadUserByUserName. Implementation of this method will be in MyUserService. It will look like this.

@Service public class MyUserService implements UserDetailsService {

@Override
public UserDetails loadUserByUsername(String arg0)
throws UsernameNotFoundException {

MyUser user=new MyUser();
/*get details of user and authorities from database whose username is
arg0 and place them in user instance */
return user;
}

}
MyUser is also a new class that implements org.springframework.security.core.userdetails.User Details and all its methods are implemented inside MyUser class. It will look like this.

public class MyUser implements UserDetails {
private static final long serialVersionUID = 1L;
/*All the variables their getter setters that you wish to store in session. And
implementation of all the methods of UserDetails go here.*/

}
Define a bean like this <bean id="customUserDetailsService" class="org.aurora.timeexpense.service.MyUserServic e"/>
Where org.aurora.timeexpense.service.MyUserService is the path of my defined service that implements UserDetailsService.

4.And Spring Security Configuration will go like this <authentication-manager alias="authenticationManager"> <authentication-provider user-service-ref="customUserDetailsService"> </authentication-provider> </authentication-manager>

You are good to go.
