Spring Security doesn't remember authenticated users - spring-mvc

Question

I am using spring-security with a Spring-MVC application. Currently I am able to login user, password hashing and all is working beautifully. Whenever I need the authenticated person object, I retrieve the name via Spring security, then by accessing database I get the user object. All good till there. Now when I load the application first time, I log in, I close the tab, and I again give the application address, I would like to check if the user is authenticated and redirect. This is where I am having problem. I went through many tutorials on net, and I am almost doing the same. Kindly have a look at what I am doing wrong. Thank you for your time.
Controller :
#RequestMapping(value = "/", method = RequestMethod.GET)
public String listPersons(Model model) {
boolean id = isAuthenticated(); // Here I am calling the function I have written to see if I am logged in
if(id){
return "redirect:/canvas/list";
} else {
model.addAttribute("person", new Person());
model.addAttribute("listPersons", this.personService.listPersons());
model.addAttribute("notices",new Notes());
model.addAttribute("canvases",new Canvas());
return "person";
}
}
isAuthenticatedFunction :
private boolean isAuthenticated(){
Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
if(authentication == null){ return false;}
if(authentication instanceof AnonymousAuthenticationToken) {
return false;
} else {
return true;
}
}

To retrieve logged in user, I am using the method mentioned below, which works like a charm right now.
#Override
public Person getCurrentlyAuthenticatedUser() {
Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
if(authentication == null){
System.out.println("User is not authenticated");
return null;
} else {
Person person = personDAO.findPersonByUsername(authentication.getName());
return person;
}
}
