session - How to uniquely identify a request in Grails?

Question

The Grails request object is an instance of HttpServletRequest. Is there any way to get a unique id from the request object? My end goal is to store session data specific to a request, so I need a String or number that I can use as a unique identifier.

Answer 1

たぶん、リクエスト属性として一意のIDを追加しますか?

request.setAttribute('UID', Math.random())

Answer 2

フィルタ内で静的ThreadLocalを使用してみませんか？
