For the latest stable version, please use Spring Framework 6.2.4!spring-doc.cn

`@SessionAttribute`

See equivalent in the Servlet stackspring-doc.cn

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:spring-doc.cn

Javaspring-doc.cn
Kotlinspring-doc.cn

@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.spring-doc.cn

For temporary storage of model attributes in the session as part of a controller workflow, consider using SessionAttributes, as described in @SessionAttributes.spring-doc.cn
