Java – Adding additional details to principal object stored in spring security context

javaspringspring-security

I am using Spring 3.0 and Spring Security 3. I am able to authenticate a user against a database using Spring Security. Using:

SecurityContextHolder.getContext().getAuthentication().getPrincipal()

I am able to retrieve username of the current logged in user. I wish to add additional details like user id and the module accesses to the principal object stored in Spring Security context so that I can retrieve it later. How can I add additional details to the principal object and then how can I retrieve it later on a jsp or java class. Please provide an appropriate code snippet if possible.

Edit: I am using JDBC to access my database.

Thanks in advance.

In order to add more details to the authenticated user. You need to first create your own implementation of the User object which should extend the spring security User object. After that you can add the properties you want to add to the authenticated user. Once this is done you need to return your implementation of the user object in UserDetailService (If you are not using LDAP for authentication). This link provides the details for adding more details to the authenticated user--

Just do it the usual way and then insert it using SecurityContextHolder.setContext() in your test class, for example:

Controller:

Authentication a = SecurityContextHolder.getContext().getAuthentication();

Test:

Authentication authentication = Mockito.mock(Authentication.class);
// Mockito.whens() for your authorization object
SecurityContext securityContext = Mockito.mock(SecurityContext.class);
Mockito.when(securityContext.getAuthentication()).thenReturn(authentication);
SecurityContextHolder.setContext(securityContext);

If you already know for sure that the user is logged in (in your example if /index.html is protected):

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

To first check if the user is logged in, check that the current Authentication is not a AnonymousAuthenticationToken.

Authentication auth = SecurityContextHolder.getContext().getAuthentication();
if (!(auth instanceof AnonymousAuthenticationToken)) {
        // userDetails = auth.getPrincipal()
}
