Access spring user object

[Darvesh Niz]

HI
I am using default spring security authentication where my user and pasword are defined in application-contextsecurity.xml file. my security concerns are very limited and i am fine with this implementation. i just wanted to check if the user name is xyz i want to dipslay some links. how can i access teh user object i am using right now a static method but not comfortable with ti. is there any cleaner solution. Any advice

 
public static User getCurrentUser() { 
 
    Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal() 
 
    if (principal instanceof MyUserDetails) return ((MyUserDetails) principal).getUser(); 
 
    // principal object is either null or represents anonymous user - 
    // neither of which our domain User object can represent - so return null 
    return null; 
}

Yep that is the only way to get the User Principal object.


But I don't see the need for the instanceof check. If your UserDetails object is of that type, and that is the only User object you have, then you will only get one that is of that type, so no need to do that check.
