包路径：org.springframework.web.context.request.RequestAttributes
类名称：RequestAttributes

RequestAttributes介绍

[英]Abstraction for accessing attribute objects associated with a request. Supports access to request-scoped attributes as well as to session-scoped attributes, with the optional notion of a "global session".

Can be implemented for any kind of request/session mechanism, in particular for servlet requests.
[中]用于访问与请求关联的属性对象的抽象。通过可选的“全局会话”概念，支持访问请求范围的属性以及会话范围的属性。
可以实现任何类型的请求/会话机制，尤其是servlet请求。
