Get User details from Session in Spring Security

I am new to Spring MVC and Spring Security. I have performed log-in and registration functionality using Spring security and MVC. I am not able to find any way for session management .

I want to access some user details on all the pages like (email, name,id,role etc). I want to save these to session object so I can get these on any of the page.

I get the following way for session in spring

Authentication auth = SecurityContextHolder.getContext().getAuthentication(); 
auth.getPrincipal();

But from the object returned by this I can get only username and password details.

But I need to access more details of that user.

Please help me to get solution for this. Thanks in advance.

I want to get my model class object to be returned from SecurityContextHolder.getContext().getAuthentication().getDetails(); For this what I need to configure.

Regards, Pranav

You need to make your model class implement the UserDetails interface

class MyUserModel implements UserDetails {
    //All fields and setter/getters

    //All interface methods implementation
}

Then in your spring controller you can do this:

Authentication auth = SecurityContextHolder.getContext().getAuthentication();
Object myUser = (auth != null) ? auth.getPrincipal() :  null;

if (myUser instanceof MyUserModel) {
     MyUserModel user = (MyUserModel) myUser;    
     //get details from model object        
}

You can use this to get the UserDetails (or any implementation with your custom details).

UserDetails userDetails = SecurityContextHolder.getContext().getAuthentication().getDetails();

If there are not available, you can load the user details from the UserDetailsService.

In both cases, I think you have to save them yourself in a session scope bean.
