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
-
@GetMapping("/") public String handle(@SessionAttribute User user) { // (1) // ... }
-
Using
@SessionAttribute.
-
- Kotlin
-
@GetMapping("/") fun handle(@SessionAttribute user: User): String { // (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.
