@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
-
Kotlin
@GetMapping("/")
public String handle(@SessionAttribute User user) { (1)
// ...
}
1 | Using @SessionAttribute . |
@GetMapping("/")
fun handle(@SessionAttribute user: User): String { (1)
// ...
}
1 | Using @SessionAttribute . |
For use cases that require adding or removing session attributes, consider injecting
WebSession
into the controller method.
For temporary storage of model attributes in the session as part of a controller
workflow, consider using SessionAttributes
, as described in
@SessionAttributes
.
