`@SessionAttribute`

If you need access to pre-existing session attributes that are managed globally (that is, outside the controller — for example, by a filter) and may or may not be present, you can use the @SessionAttribute annotation on a method parameter, as the following example shows:

Java

@RequestMapping("/")
public String handle(@SessionAttribute User user) { (1)
  // ...
}
